User Reviews
“2 stars is being generous. This esim worked for about 1GB of the 5 and then simply stopped working. The helpline had some weird story about how I should have bought an esim with blue routing and I had one with red or vice versa or something. But why it couldn't connect anymore to any of the 4 supported UK networks they couldn't explain or rectify. Waste of time and money.”
“Did not work at all, despite APN helpline etc.
Cheap, but money thrown away.”
“Good connection and price, but deceptive dark patterns during checkout
The eSIM performed well in Canada with strong coverage and good speeds. However, Stellar uses misleading checkout design to sell an unwanted antivirus subscription:
* Tricky UI: Unchecking the optional protection box during payment actually adds it to your order, with no option in the UI to remove it.
* Delayed Separate Billing: The antivirus subscription fee is charged separately ~6 hours after the eSIM purchase.
* Weekly Subscription: The add-on is a recurring weekly subscription (€0.50 for week one, then €0.99/week), not a single payment.
* 24-Hour Cancellation Lock: While a cancellation link is provided via email, the system prevents you from canceling until 24 hours after purchase.
It only cost me an extra €0.50 eventually, but setting up so many checkout traps is disappointing for a company that markets itself around security. Be very careful at checkout.”
“After the initial payment they kept charging my creditcard. eSIM was working fine though. Better avoid this company”
“Never again! They added me to autopay for a €0.99 monthly service which I've never wanted and it took multiple emails to support to get them to cancel. This is a fraudulent company and there is nothing indicating they're actually based in Switzerland. Over email, they downright refused to provide any company info.”
“Possibly SCAM!
Unlimited plan (10Mbps) throttles after 30GB data usage to 0.1Mbps.
Contacted support. no response after 8 hours.”
“After comparing plans on esimdb.com, I chose Stellar’s 3GB/30 day data eSIM. Both the purchase and installation went ok. The data works on 5G straight away at high speeds, with no dropouts or issues. The free VPN is a nice bonus. ”
“Bought an eSIM for 3 days from Superalink because I ran out of my local operator's data at the end of the month. Got an email, activated, it all worked fine without issues. Just needed to enable roaming in the eSIM options, I think.”
“Good value eSIM with excellent support! I had some trouble getting the eSIM to work, which apparently was due to a configuration exception in Monaco's network, but SimBalkan's support got back to me minutes after contacting them and provided me with a precise solution, instead of a long list of try-this-try-that. I am therefore very happy with the service!”
“I bought a 48 GB eSIM, at first it was okay, the speed wasn't very fast but I could browse websites, YouTube was difficult. Once I had used half of the data, it became unusable, nothing would load, not even a webpage. It's really cheap but the service keeps cutting out and I tested it in several cities in China, same problem.”
“I have been signed up to a recurring subscription I never agreed to: "Stellar Antivirus 1 weekly - eSim Upsell", €0.50 for the first week and then €0.99 every week thereafter, billed separately to my card. I unchecked every add-on box at their checkout. Every single one. I did not consent to being charged, and the only way it ended up on my order is because THEIR checkout is built to slip it past the customer after they have declined it. They are SCAMMERS. I sent them an email to ask them to stop, they said it's non refundable. I NEVER AGREED TO PURCHASE THIS SERVICE. I emailed them 9 October at their request to 'confirm' I wanted to cancel. THEY STILL CHARGED ME 15 OCTOBER. THEY ARE SCAMMERS.”
“Absolute garbage. I had issues with the eSIM and reached out to them for support, all they did was refund my money. Do not use!!”
“I've used Truely unlimited data in UK, Serbia, Thailand, Turkey and KSA during my backpacking trip. The unlimited data was genuinely nice considering I had to work while traveling. I had issue with the KSA plan once but was fixed pretty fast. The rest of the destination was all good.”
“Good ”
“I bought their 'Unlimited' plan for one day, just to try it. It was fine for most of the day (I got ~7GB from it), but at some point the eSIM just stopped working and would not connect to any mobile network anymore. I'm guessing they decided that I violated the 'fair use' policy (although I did not tryb to). But the fact that in such case they just shut down the eSIM without any warning is unacceptable. ”
“Don’t buy!!!! Beware of upselling scam and very low speed and high latency!
When buying an eSIM you have to double check not to buy an upselling package for a weekly subscription for a useless “antivirus” product. Immediate cancellation is not possible and support not helpful. Wouldn’t buy again. Be aware!
And the speed and latency is just horrible. Shows 5 bars reception but 800ms and less than 1 Mbit in the middle of Hiroshima.
No way!”
“After buying the esim. No one will send you esim during 30 mins. Its a scam”
“Stay away! They charge your method of payment every week after you purchase your e sim for some bogus travel protection you did not sign up for. FRAUD COMPANY”
“I tried to start with the free offer, but it was not possible. It asked for credit card, then charged me in Zloty and credit back in USD. This means I paid commissions to the credit card company on exchange rates. Than, it forces you to follow on both Instagram and TikTok, but the worst thing - they never approved my request.
I ended up with another eSIM.”
“The company uses deceptive tactics. Do NOT trust them.
Throughout the eSIM ordering process, they do everything they can to get you to subscribe to their antivirus and protection service. I noticed this and deliberately unchecked the option, yet I was still subscribed. The first week is free, so you aren't charged right away.
When I tried to unsubscribe, the option wasn't available. The unsubscribe button only becomes active after 24 hours. Fortunately, their support team responded quickly and canceled the subscription after I emailed them.
However, this is completely unacceptable. I shouldn't have to waste my time on something I never asked for. I won't be buying any eSIMs from this provider again.”
“5 days unlimited in Kandla very slow enough only for chats. Cannot watch videos continuously.”
“Esim did not work. My friend had the same experience with a different phone. Communication with helpdesk is difficult. After 10 emails and lots of screenshots and following all kinds of instructions the problem is still not fixed. They keep on asking screenshots of screens I already shared and refuse to refund.
”
“Bought the giga.tel European SIM - it worked for a few hours but stopped working 3 days ago, so most of the time no data at all.
Tried their support on both WhatsApp and email - no reply at all.
Do not be tempted to buy!”
“Bought Stellar Security's Thailand 20GB/30-day eSIM. It installed but never connected or gave me data. I tried different locations, manual network selection and a restart. On 27 August, support confirmed in writing that the eSIM had not started a data session. They said my refund request was referred for review, but never sent the decision. When I followed up, I got repeated copy-paste refusals saying the QR code was delivered, with examples of an eSIM not installed or the wrong destination. Neither applies to me. I asked for a technical review and got the same template again, with no session-log evidence. EUR 5.59 isn't a lot, but I paid for data I couldn't use and still have no refund.”
“I have bought this esim, not the cheapest but 20GB/30 days plan for my son. The performance is pathetic, barely usable at all. Works only now and then, often struggling to connect, extremely slow even when connected. Customer support zero, they claim response in few hours, byt none received in a day. Waste of money. Waste of time that should had been spent enjoying holidays, rather than dealing with poor quality service provider.”
“Their Central Asia 4 eSIM worked fine for texting and sending pictures. Could no test further as the users I purchased them for didnt need more than that”
“The signal looks great! But data transmission is terribly slow.”
“Terrible. Don't use this. Bots make you circle around with solutions that does not work. Human intervention just repeats that circle. Do not buy. They are also causing problem with refund stating it defaults to their "wallet"”
“Mam bardzo złe doświadczenia z tym dostawcą. Po 1 - wybierając eSIM w ukryty sposób dają Ci jakąś subskrypcję ochrony, za którą płacisz 0,50€, jeśli nie napiszesz i nie anulujesz tego to płacisz bez końca. Po 2 jeśli klikniesz automatyczne doładowanie to zrobią Ci je praktycznie od razu - niby po zużyciu 50%. Tak więc biorąc 3GB, nagle nasz 6GB, a wykorzystasz tylko 2GB.
Po 3 - automatycznie dopisują Cię do newslettera i dostajesz tonę spamu. Nie polecam. Lepiej wybrać coś innego.”
“This was a very disappointing experience. I purchased an eSIM from StellarSecurity, but it could not be activated, leaving me without service and out of pocket.
What made the situation worse was the customer service. They provided no effective solution and were unwilling to properly resolve the issue or refund my money.
Based on my experience, I would strongly advise against purchasing an eSIM from StellarSecurity. They literally steal from you.”
“Watch out for FRAUDULENT practices:
When you buy an eSIM, they just add an antivirus subscription to your order! That means: long after you’re done using the eSIM, you’ll still be paying for that antivirus subscription!!
At checkout, they add that subscription which you obviously didn’t want, and even if you notice it and click that “No thanks”-button, they’ll still add it and it will appear on your order.
So, if you never spot that €0.99 charge every week on your credit card bill, you’ll be paying it for years and years…”
“Deceptive checkout, delayed hidden charges, and broken dashboard!
I placed an order in the evening just to buy an eSIM for Italy. Without clear transparency, Stellar Security automatically added a "Stellar Travel Protection" subscription to my cart. Then, at 3:00 AM, an unexpected separate charge of €0.49 was processed on my card for this protection, with a scheduled recurring monthly bill of €1.39 to follow.
To make matters worse, when I logged into my account to cancel it, the dashboard displayed "0 Active Subscriptions," making it impossible to cancel through their interface. On top of that, their email login verification code failed to arrive promptly.
Charging customers' cards hours after checkout for unwanted subscriptions while hiding them from the account management panel is completely unacceptable. Beware of hidden fees and check your bank statements carefully!”
“Worked well Giza and excellent customer support, no chat bots.
Recommended”
“The eSIM only connects to EDGE in Serbia, making mobile internet practically unusable. Sometimes the connection disappears completely for hours.
I followed all the troubleshooting steps suggested by support, but nothing changed. The support team keeps asking me to repeat the same basic steps instead of actually solving the problem.
Very disappointing experience. I would not recommend this service.”
“The SIM card works only with “Türk Telekom” and “Vodafone Turkey” networks. During the day, the internet speed was good, around 20 Mb/s, but every day after 6:00 p.m., the speed dropped to 1–2 Mb/s. This was very frustrating, and sometimes web pages wouldn’t even load. In my opinion, this isn’t the fault of the eSIM provider, but rather “Türk Telekom.” The solution to this problem is to manually select “Vodafone Turkey” towers on your phone. On Vodafone towers, the internet works reliably at all times.
You must install the eSIM before arriving in Turkey; otherwise, you won’t be able to do it. Turkey blocks eSIM installation. This applies to every carrier.”
“Unfortunately, the card only connects to “Türk Telekom” transmitters. During the day, the internet speed was good, around 20 Mb/s, but every day after 6:00 p.m., the speed dropped to 1–2 Mb/s. This was very frustrating, and sometimes web pages wouldn’t even load. In my opinion, this isn’t the fault of the eSIM provider, but rather “Türk Telekom.”
You must activate the eSIM before arriving in Turkey; otherwise, you won’t be able to do it. Turkey blocks eSIM activation. This applies to every carrier.”
“Works perfect, and affordable prices.”
“I bought this one many times in multiple countries and it always worked”
“Not working. I bought their esim 2 days ago. Emailed them about my issues. Support got back to me actually quickly. I got a 'replacement esim' that one worked for less than 15 minutes. The support person escalated the issue and I'm still waiting for their reply.”
“I hired a 10 day plan with 7 GB. It stopped working after about 12 hours (just when I needed to get an Uber in not the safest place of town) and only 300 MB of consumption. Never received an email with the confirmation of purchase, so I can't even get a refund because I lost my transaction number. Do not buy, it's a scam”
“Decent speeds in all the tourist areas. Ping increase not too bad as traffic is routed through the Netherlands where traffic needs to go to for EU Servers anyways. Underlying provider is TIM Italy. Coverage outside of settlements/cities is low but thats outside of Jambos control.”
“Worked flawlessly with great signal. The auto top up feature didn't work, but manual top up went great. Loved the price and will use again!”
“Its perfect esim in Iran”
“Awesome ”
“I've taken 2 esim with Stellar for our stay in Italy. Connection was really poor and when requesting Stellar support, Matthew didn't feel any hurry or attention to solve our problem. I ended up by buying another esim from another provider and I've asked to get reimbursed without any answer after 10 days. Worst experience ever ! Stellar to avoid”
“ESIM.DOG's North America eSIM (AT&T USA/Freedom Mobile Canada) automatically connects to other networks as well (Verizon, T-Mobile, Bell, Rogers, and TELUS) while not transmitting data. Manual network selection is necessary. Support leads you in circles. Freedom Mobile has very limited coverage outside major cities.”
“First time using it”
“Do not use them. They charge you extra fees (€1.49) you never agree to pay and sign you up for a subscription you never agreed to buy. They claim it’s a travel insurance. When you contact them the don’t refund you. Scammers”
“I cannot recommend this provider.
My purchase confirmation email contained the complete eSIM activation QR code and activation details, but it was also CC'd to a personal Gmail address (praveenasaravanan95 -at- gmail dot com). As far as I can tell, anyone receiving that email also receives everything needed to install the eSIM. I reported this as a potential security issue and repeatedly asked to speak with a human, but only received AI-generated replies. My request for a human representative was ignored.
In addition, there is no purchase history or data usage information available in my account, so I have no way of verifying how much data remains on the eSIM.
Although the eSIM does connect and appears to work, the lack of transparency and the apparent disregard for a legitimate security concern mean I cannot recommend GigaTel.”
“Very disappointed with my experience with Giga.tel. I purchased an eSIM, but during the very first installation attempt on my iPhone 13, the QR code displayed the message, “This code is no longer valid.” However, the eSIM had never been installed or used.
I contacted customer support to request reactivation or a new QR code, but I received no response despite following up several times.
Technical issues can happen, but the lack of response from customer service is very disappointing, especially for a service where line activation is essential.
I hope a solution will be provided quickly.”
“Did not work first time, had to contact support to get a new esim. Routes through London, hence high latency/slow”
“Switched to Roamify unlimited (with discountcode working) for a few days in Russia and had very good speed and service. I think to remember that there was a 10GB calendar day limit of high speed data after which the speed was throttled but still at a very useful 5-6mbit/s. Experience from aug 2025, so before the 24h block when entering the country limitation.”
“SCAM. not working, no help from globalesim. BOT chat with globalesim to end your chat session.. Unable to receive refund.
Unable to send email : Your message wasn't delivered to cs@gloabalesim.app because the domain gloabalesim.app couldn't be found.”
“Fast delivery and good quality”
“Absolutely terrible. Unusably slow speeds and the random country VPN exit point means many sites won't load.”
“Unfortunately the internet didnt work after 2 days”
“I'm using wifio's Unlimited 30d eSIM in Basel and it works flawlessly at 5G. Can recommend.”
“Tried the 20GB / 30d variant from orange travel in Basel. Stay away from it - It disconnects intermittently for no reason, even when other providers have signal from the same network.
I asked for a refund and KUDOS to orange's customer service. I received a positive answer and a refund confirmation within an hour.”
“Very bad experience (not being able) using it in the Dutch Carribean with iPhone 17. Support reply was good but not able to solve the problem. Also not willing to refund. Never again.”
“Worked well around the broad Athens area!”
“Found the cheapest 50GB plan. Ordered and I've got no confirmation, no information within my account on their page, nothing. WhatsApp support very quick and responsive, though can't help much. Since I've got no plan nor any information, they've said 'will forward to shift manager' couple of times. I had to push them multiple times to receive my Esim. Zero empathy, zero apologies, nothing offered as the apology. Esim arrived 3 HOURS LATE manually into the WhatsApp without any confirmation or whatever, just 'that's your esim'. DO NOT RECOMMEND. Though Esim plan so far working fine, but everything around ain't worth trying to save. BIG REGRET.”
“4g only, no 5g”
“Didn't work!”
“G”
“This is fraud. I paid and received the payment confirmation email. Then never received the eSIM even though they claim sending it within 30 minutes.”
“Worst customer service I've experienced in a long time. I've been using Airalo for a couple of years without any major issues, but recently I've been dealing with repeated connection problems.
When I tried to get help, I spent over 30 minutes chatting with an AI bot that never resolved the issue or connected me to a human representative. The end result was simple: no data, no solution, and no refund. Very disappointing experience.”
“It´s a good esim, especially the no expiry version. I load data and use it every time I get there and top up when needed.”
“Faulty company, date start count from purchase not when activated. never get support and refund.”
“Generally very good coverage across Michigan with 5G in detroit. Didn't work in more rural areas where AT&T signal was available whereas my partners cheaper sim from esim dog worked okay. Overall good experience ”
“Generally very good coverage with 4G in smaller towns and 5G in Toronto. Simple setup process and no problems.”
“I bought a 31 day 20GB esim europe card from esimcard.com. This card has a france phone number with unlimited voice and SMS. The esim card was advertised with 5G networks. However, Only 4G speed was experienced, even in Paris and other big cities. Voice phone call call can be made in first 20 days, then you requested to register to Orange to continue to make phone calls, but orange registration page always hung, you could not register. I opened two tickets, but have not got any help.”
“every good”
“My eSIM stopped working after a few days whilst abroad. The seller promised to refund the sale and after 6 weeks still haven't acted on their promise. They continuously say "let me check" with no results, no refund. This outfit will ruin your travels. Stay clear.”
“DO NOT PURCHASE, THEY WON'T REFUND YOU IF THEIR SERVICE DOESN'T WORK. Didn't work at all. Went round and round with their support with no resolution and no connection. I wasted several hours of my day trying to get it to work. To add insult to injury, they refused to issue a refund for their nonfunctional service, and I've had to pursue a chargeback with my credit card company.”
“The esim caused 2 APNs to be set up. The default APN Orange did not work with Rogers in Canada. Selecting the second APN nju got the mobile data going.
Internet breakout was in Poland. There was a noticeable but acceptable delay.”
“Fraud, did not send eSim. Not recommended. Avoid that service.”
“Very slow, it's no longer useful for anything except text”
“I’ve used multiple eSIM providers from here and this eSIM.dog is the worst one I’ve encountered. Connectivity issues extremely slow and unstable/disconnecting every 5 min for 5-10 minutes on repeat. Waste of money. Do not purchase from this provider”
“horrible speeds, connects to slowest provider”
“Had a great experience with Ozly in Japan. The eSIM had trouble connecting at first but eventually succeeded after some fiddling in the phone settings (the provider's AI chatbot actually gave me a helpful tip). Got a local IP so no geoblocking. Speed was satisfactory and I got signal in every city I visited (Tokyo, Hiroshima, Fukuoka, Sapporo and a few smaller ones) except in one rural area in Chiba-ken. For the price I paid, it was an incredible deal.”
“Incredible! Excellent eSIM for the price. Our children can watch YouTube and play whenever they want.”
“It worked for a short time and I downloaded about 3 MB of emails. Then I disabled data roaming and renabled it the next day when I didn't have wifi. I could not get it to work again - the phone kept prompting me to set a carrier name. There was no help on their website. I never got it to work so my money was wasted. They send me an email with a link to review the purchase but that did not work. They claim to refund non-function sims if you email them but I have emailed twice with no response. I think this company should not be trusted.”
“I bought the eSIM for Canada through esim.dog (9GB, 10 days, Rogers). I like how transparent they are about where the SIM card termination and network is located with multiple options. Setup was smooth, and I just had to remember to turn on Roaming after activating it. Speeds are decent with latency of about 257 ms (thanks to termination in UK/Poland), but it seems like all”
“I previously left a negative review, but after trying this eSIM again for my trip to Turkey, I want to update my opinion.
The connection worked perfectly during the whole trip — stable, fast internet with no issues at all. The price was also very low compared to other providers, which was a nice surprise.
The only issue I had was that the QR code was not sent automatically to my email after purchase because I used the express checkout option without registration. The website chat didn’t work, and it was very difficult to even find their support email since the site doesn’t clearly show any contact information. However, after I contacted them by email, support quickly sent me the QR code and everything worked fine after that.
Overall, a much better experience this time. Good speeds, reliable service, and great pricing for Turkey.”
“downloaded app to iphone - nothing works. frustrated. app deleted.”
“I bought 10Gb for 7 days but was given unlimited for 3 days. For some reason I was switched.
This is bad. This is incorrect marketing and a switch during the checkout process. I will never purchase from your company again.
Data speed was not good either.”
“Satisfied, fast, smooth. I didn’t have any connection problems.”
“Purchased esim for use in Spain, had no issues. Sim activated quickly and received instructions via email. Speeds and connectivity were good would use again in future.”
“I paid for the purchase, nothing came to the mail, the support is also dead.”
“Setup was super easy and the speeds were great through our whole 30 day trip”
“Update: they refunded later”
“Uses the TN Mobile network which was only the bigger cities and even when it got a signal it seemed extremely limited or restricted speeds.
A setup using the MTC network really would be the best option as it was much more widespread network.”
“This eSİM claims to roam with 2 Turkish networks, which was my reason to buy. This is not true. Like many other travel eSİMs, it connects to Avea/TT only. Turkcell, although mentioned as a roaming partner, does not connect, says "not allowed"
I contacted support, but they behave as if they do not understand. Final recommendation, after a couple of emails, was to just set the phone to automatic selection. Hey!”
“I noticed that the pay-as-you-go option does not appear in the plan listings on esimdb, which caught my attention a little. After actually using it, I personally feel this is the most convenient option.
Because it is fully usage based, you can keep using it seamlessly even when moving between countries, which is incredibly convenient. With cheaper flight tickets, long layovers at airports in China are common, and sometimes you may want to head into the city for a short while. In those situations, it feels a bit wasteful to purchase a one day plan or a large data package, so this option fits perfectly.
Airport WiFi is available, of course, but connections can be unstable, and SMS verification is sometimes required, which often makes it more troublesome than expected. That is why having the reassurance of being able to connect immediately on your own mobile line, even during immigration, feels very valuable.
Overseas roaming is also available with ahamo and Rakuten Mobile, but there are still countries that are not covered. Having this set up as a dual SIM feels like something that could really help in an emergency. I also appreciate that LINE and WhatsApp continue to work even after the main data allowance has been used up. It is a small detail, but genuinely useful.”
“I selected their best coverage plan for 10 GB and I had no coverage at all. I failed to set up at the airport, in the taxi. Then I connected for a while at the hotel beach, but I could not connect anymore again. Total waste of money, they refused to refund because I used 64 MB of data already. Then I purchased Yesim 1 GB and had the coverage immediately.”
“OK”
“It is operated by China Mobile when you use it in Taiwan. It means that you need to submit your passport info and photo in order to use it. Or, you paid and activated but you are off line.”
