Use code ESIMDB15 for 15% discount. Limited time only.
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.
