“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.”
“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!”
“Title: WARNING: 100GB Plan Blocked After 25GB Use – Stay Away
I purchased Airhub's 100GB plan specifically for its advertised data allowance. However, after using only ~25GB in a few days (only 25% of the plan), the service was permanently blocked.
I spent 11 days emailing support, only for them to finally admit:
"Please note that your eSIM has been temporarily suspended due to abnormal data usage within a very short period of time, as detected by the network. This action is taken automatically to prevent unusual or excessive usage."
Selling a 100GB plan and then blocking it for "abnormal usage" at 25GB is deceptive. They have refused to reactivate the line or offer any refund for the 75GB of data I never received. Do not trust their advertised data limits. ”
“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 purchased an eSIM from Yatelo for India, 5 GB for 30 days. It worked for only one week, I had used up only 0.5 GB of my data and it stopped working. No more Internet all day in different locations.
I wasted about 40 minutes with their online support, they suggested endless things to try, none of them got the eSIM working again. They then refused to refund the money, saying they were escalating to the engineers. ”
“Great and affordable e-sim. Everything functioned great”
“I bought 4 esim for Japan travel. Very bad experience. For the first day, it auto connected to Softbank service, and extremely slow and lost connection from time to time. Checked the usage, it's less than 1GB usage. The customer support was useless. Will not buy it again”
“I do not recommend this site for purchase. Before purchasing, I came across a number of negative reviews, but I decided to try my luck anyway. Here's my experience: In Uzbekistan, everything worked perfectly for one day, but the speed was terrible on the second day. In South Korea, everything worked well, but in China, everything worked well for two days, and then the internet simply disappeared, even though I still had plenty of data and time left. There is no support, and the AI agent responds by saying that I am doing something wrong.”
“Really bad customer support”

“The application is good and the coverage depends on chosen supplier. Some suppliers are good, others need to be enhanced. The speed and coverage depends on the service provider and on the country infrastructure. Rate is acceptable.”
“I bought it for my short trip in Kazakhstan and got great experience due to routing in United Kingdom (most of eSIM providers use Singapore routing that is really slow in Kazakhstan). On LTE I've got 50-100 Mbps download and 50 Mbps upload speed.
So I definitely recommend buying this one for Kazakhstan to get stable connection without issues.”
“Hello, I purchased an unlimited data eSIM from esim.dog for my 5-day Umrah trip to Mecca, and it was a terrible experience from start to finish. Despite the signal being strong, the internet speed never exceeded 200kbps, making it impossible to browse.
I am aware that Saudi Arabia has certain internet restrictions, and I even used a paid VPN service to try and fix the issue. After switching between multiple countries on my VPN, I was barely able to use WhatsApp for texting. Web pages wouldn’t load even after refreshing 2-3 times, and images were non-existent. Without a VPN, I couldn't even access local Saudi flight or train booking sites. This was easily the worst eSIM service I have ever used. Think twice before buying.”
“Used Micro-Esim for the first time, went great.
Bought online, got sent a QR code by email, downloaded it to my android and installed it, had it off as second SIM until landed in China and then turned it on, worked great for the time I was in China.
Could not get Instagram or TikTok to work but that will be due to country rules and not the SIM.”
“Very good Experience”
“Able to activate this eSIM from Indonesia however unable to connect to any provider in Singapore. Refund process was quite easy. I gave two stars because of how easy the refund process was otherwise one star.”
“Pre-installed Nomad eSIM on a 10GB/30day plan. Activation at the Guangzhou airport after a 15 hr flight was bit challenging. I used the combination of Airport Wi-Fi & Firsty Tier 1 Free Basic to bootstrap start Nomad. Provisioning and activatin took less than 5 minutes max. Nomad has implied VPN features, so to really use the cellular connection service provided by partner China Telecom, under Settings I disabled wi-fi in my iPhone 16 and primary SIM. I was able to access 90% of my Apps (normally blocked: YT, FB, WhatsApp, Outlook emails, Gmails, etc.). Some locations even with signals at 4-bars, both eSIMs appeared not working, that is the network connection issues and not the eSIM's fault. Overall very satisfied with Nomad (paid) DL upto 90Mbs and Firsty (free) 230Kbs as backup.”
“Good esim”
“Delays, Misleading Product Info, and a Frustrating Refund Process
I bought two 33GB eSIMs for the Philippines and they were completely unusable — SMART required local‑resident documents, which Airhub never mentioned. Support ignored my ticket for 17 days, then claimed they had replied (they hadn’t) and even leaked another customer’s email in a screenshot.
After weeks of excuses and delays, they only offered a 50% refund for a service that never worked at all.
Unreliable service, misleading info, and very poor support.”
“Honestly its the first time i tried esim from Strong esim and i only chose as it was the Cheapest esim deals i could find. But it worked very well and no issues whatsoever”
“Scammers - purchased esim, received no confirmation of order and no login. Tried to access support and no response. No idea why esimdb are allowing this site to advertise”
“Never received the esim. Support chat doesn't answer.
”
“I've paid but haven't received the esim qrcode or email.”
“reasonable prices, good connection. never lost connection before expiry date & time.”
“Seconding what another user wrote: speed is really slow, about 0.3 Mbps in UAE..”
“Good”
“Scam! Their global sim DOES NOT WORK in Maldives!”
“Purchased for 7 days and worked perfectly”
“10GB for 7 day ESim. Seemed to work fine at first in Haifa area, albeit with signal strength coming and going. When I moved to Tel Aviv area, the ESim stopped connecting to the network entirely. Support (via e-mail) were unable to resolve the issue, so they offered to refund me but I have yet to receive it”
“Terrible company. Scammers! I highly recommend not using them! I got an eSIM for India. I set everything up according to the instructions. But the SIM won't connect to any carrier! Support said they'd help me within 24 hours, but three days later, they haven't responded. My vacation was already over, so I asked for a refund. After much persuasion, they said it would be returned in 2-3 days. It's been 9 days now, and I still haven't received a refund! Support hasn't helped at all. They simply stole my money.”
“Its not working and they are just reading my messages with no response? Is this a scam??????? Very frustrating”
Everything you need to know about using eSIMs in Asia
Asia offers around 130 travel eSIM providers and more than 4, 600 prepaid data plans. With such a wide variety of options, travelers can easily find a plan that fits their needs.
Unlimited data eSIM plans for Asia are available from several providers. AbesteSIM, Billion Connect, Roamify, Truely, Yesim, and FairPlay each offer plans with no data cap for periods ranging from one to thirty days (Yesim extends to eighty days). All of these plans allow tethering but may impose speed throttling; for example, abesteSIM caps the speed at 5 Mbps with a reduced speed of 128 kbps. Prices for these unlimited plans start around $2.38 USD and can go up to roughly $231.01 USD, giving travelers a broad range to match their budget and data needs.
Travel eSIM plans that provide a phone number and SMS functionality are available for Asia from providers such as GlobaleSIM, Roamify, Orange Travel, Earth Esim, Airhub and TravelKon, and others. These plans offer inbound and outbound voice and SMS (except Airhub, which lists only voice) and use dialing codes of +1 (U.S./Canada), +33 (France) or +44 (United Kingdom), so the numbers are foreign international numbers rather than local Asia numbers.
The cheapest options begin around $4.00 USD for a 1GB data add‑on with 7‑day validity, while larger bundles such as 20GB for 30 days or 5GB for 60 days reach prices up to roughly $95.00 USD. Validity ranges from 7 days up to 365 days, allowing travelers to choose a period that fits their stay in Asia.
