“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 get the activation done and get the connection. Or, you paid and activated but you are off line. The quality of connection is not good. For some apps, it fails to connect the internet.”
“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.”
“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.”
“It's a little annoying having to submit passport for authentication but speed and latency is good. Also customer service is easy to reach by Whatsapp and really responsive and knowledgeable.”
“Avoid. In order to buy their product (the link through eSIMDB is invalid) you must register (to buy) through either thru 1) phone number 2) Google (social sign-on) or Apple.
Their rates are extremely low and basically too good to be true. I wasn't able to reach support. Avoid.”
“Fast speeds on Chunghwa Telecom's network through an Hong Kong service provider, which means that unless you connect to a VPN to override your location, websites/apps will think you're accessing them from Hong Kong. Minor annoyance for a very affordable and reliable eSIM though.”
“The sim isn't working if your don't provide your passport, I'm a taiwanese resident and can't use my card before it's transferring this data to china”
“Easy to use through the app, the price was very good (and there are coupons around through many sponsors if you search). But was kinda slow at times, up to the point it was unusable for ~1h. Difficult when relying on Google Maps for bus transfers.”
“So far all the esims I've got with mobimatter worked flawless, in Taiwan I had to adjust the connection network manually once, but it was a minor issue.”
“The esim works but there is a undocumented step in the process.
After you scan your qr code, save the esim to the phone, enable data roaming, etc, It still wont work because you need to REGISTER it with 3 hong kong via a url (even though it says kyc registration not required, it actually is). I only figured this out after ripping my hair out and scrolling reddit for 2 hours.
you need to look at your phone's settings, get the phone number of the phone plan and register it with the url:
https://www.three.com.hk/prepaid/account/en/rnr-reg
(you can only visit this site when it shows you are connected to carrier (ensure it is only chunghwa telecom ONLY ) and but not the internet (pic attached) )
once you open the url, you need to type the word passport in document section and provide a passport number in the document number section. then a green checkmark box will say success.
after wait around 5 minutes, put into airplane mode and turn off, then it will work.
Like the process is very confusing because they don't tell you this but it is the cheapest data provider for 22 AUD which is hilarious. ”
“The eSIM works well as expected in the 3 countries I visited recently: UK, Thailand, Taiwan. They send reminders when data is almost used up.”
“The eSIM activates quickly and automatically and connects to Chunghwa Telecom once you turn on data roaming on the phone. Works well as expected.”
“The SIM activates and connects to Chunghwa Telecom but doesn't have a data connection. It doesn't work. Service is not available during local daytime hours as they are on European time.”
“When your speed test app can't even connect to the network, you know you're in for a bad time...
I think the problem here is that all the eSIM solutions for Taiwan seem to be routed through Hong Kong — as such, latency ranges from barely acceptable to extremely frustrating.
Meanwhile a physical SIM from Chungwa (or Far EasTone) has fast *and* unlimited data — plus a local number; you just have the extra bother of registering with your passport at the airport.”
“I used an eSIM for the first time in Taipei between September and October 2023 (5GB/5 days = $4, which was 609 yen at that time). Initially, I couldn't set it up properly on my iPad mini 6 and had to go through some trial and error, and ask friends for advice. Eventually, after deleting an existing profile, I managed to get it working. Once it was set up, I was able to use it without any issues.
My usage was mainly for messaging, LINE calls, map searches, etc., and I only used social media occasionally, so I never exceeded the data limit nor experienced any connectivity issues. I didn't measure the connection speed, so I'm not sure about that.
However, since I had to delete the profile I usually use in Japan, I had to reinstall and reconfigure it upon returning, which was a bit of a hassle. So, it might not be the best choice for someone who finds that process daunting. But the affordability was a plus.
As an aside, when I used MayaSIM on a later trip to Hawaii, I didn't need to delete any existing profiles. It connected to the internet within minutes of activating it at the arrival airport, and it was very convenient to be able to check my data usage on the dedicated website, receive an email notification when I had used half my data, and purchase additional data. Highly recommended.”
“The actual Internet breakout is Hong Kong via a China Telecom HK IP. Speed and latency in Taiwan are decent, but limited to 4G networks like most roaming-based eSIM.
Remaining data is shown in the user area on their website.”
“Purchase was easy and straightforward. Their eSIM worked well in Taipei, with download speed of around 80Mbps and latency of 120ms (Hong Kong IP address). I got 5G most of the time.”
“Cheap, but bad connection quality. When surfing, it get disconnected regularly. For voice calls, it gets disconnected so often that it's almost impossible to talk.
Opened a ticket several days ago. No news...”
“Reselling cards from 3HK, which is normally alright (Korea, Japan, etc) but not Taiwan. Latency when using this card in Taiwan is very high, over 200 ms (Hong Kong is less than 100 Km away). Also a lot of sites block access with this provider, including Netflix for example. Speed is alright, but latency makes it at times unusable.”
“Poor reception at times, routing via Israel with very high latency, some pages do not even open.”
“Card works great, routed via Hong Kong 1010 network. It appears to be limited to 80 Mbps. Other cards from other operators can easily do 200 or 300 Mbps on the same roaming network and same locations.”
“Airalo in Asia is definitely bad. The Pie Zie card gave me an IP From Israel, very high latency and slow speeds.
In Japan, often lost signal with Airalo.
In Korea, same as Japan.”
Taiwan Travel eSIM FAQ
Everything you need to know about using eSIMs in Taiwan
How many travel eSIM brands (providers) are available for use in Taiwan, and how many prepaid data plans are there?
There are more than 180 travel eSIM providers and over 8, 700 prepaid data plans available for use in Taiwan, providing travelers with a wide variety of options to find an eSIM that suits their needs.
Are there any unlimited data eSIM plans available for Taiwan?
Several eSIM providers offer unlimited data plans for Taiwan. MicroEsim, Roamify, Earth Esim, abesteSIM, Truely, Yesim, CocoRoam, FlyEsim.me, Ohayu, and FairPlay list unlimited data as a feature in their product offerings. Some of these plans include speed throttling or specific speed limits, such as 5 Mbps or 10 Mbps, and in one case a 1 Mbps limit, so it is advisable to verify post‑activation performance. Prices for the unlimited data plans typically range from about $2.60 up to close to $40 USD, depending on the provider and validity period. If an unlimited plan is not required, users can estimate their data needs based on intended activities—streaming, browsing, navigation, etc.—and choose a plan with an allowance that covers those activities comfortably.
What are the major mobile networks available for a travel eSIM in Taiwan?
Chunghwa Telecom: "Taiwan's largest telecommunications company, offering extensive coverage and a wide range of services."
Taiwan Mobile: "A major provider known for its comprehensive mobile services and strong network infrastructure."
Far EasTone Telecommunications: "Offers robust mobile services with a focus on innovative solutions and customer satisfaction."
Asia Pacific Telecom: "Provides mobile and fixed-line services, emphasizing competitive offerings and customer service."
Taiwan Star Telecom: "Focuses on mobile communication services with a commitment to expanding network coverage and quality."
In Taiwan, Mobile Virtual Network Operators (MVNOs) offer mobile services by leasing access from major carriers. One example is Vibo Telecom, which provides various mobile services to consumers. However, most travel eSIMs rely on the infrastructure of the primary Mobile Network Operators (MNOs) rather than MVNOs.
Can I get a travel eSIM with a phone number and SMS for Taiwan?
Yes, several travel eSIM providers offer plans that include both a phone number and SMS capability for use in Taiwan. Providers such as GlobaleSIM, EtravelSIM, Roamify, Orange Travel, Airhub, and eSIMX supply phone numbers that can receive voice calls and SMS, with voice services available inbound and outbound. The dialing codes for these numbers vary: GlobaleSIM, Roamify, and most of the other examples use the U.S. code +1, EtravelSIM and many European‑based plans use +44 or +33, while Airhub and RedEx eSIM offer local Taiwanese numbers with the code +886.
Prices for these plans start around $4 for a 7‑day, 1 GB package and rise to $100 or more for larger data packages, with validity periods ranging from a few days to a full year. Travelers who need a local number in Taiwan may prefer Airhub or RedEx eSIM plans, whereas the other options provide foreign numbers that still work for incoming calls and SMS but may not be recognised as a local Taiwanese number. If a strictly local number is required, verify that the chosen provider’s number is capable of receiving calls and messages on Taiwanese networks before purchasing, and remember that data‑only plans remain a convenient alternative for communication through VoIP apps.
