Guest User2026-02-08

Great for everyday use. Convenient and easy to use. However, sometimes if I use too much, it might run out faster than the set date. But it's still cheap and economical.

★

Guest User2026-02-08

Excellent service, cheaper than buying SIM cards from a 7-Eleven, decent internet, very convenient to use because you can tailor the length and volume to your needs. Highly recommended!

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

Everything worked great!!! I don’t remember how I did it, I need to repeat it soon, but I don’t remember how to buy and switch to a number.

★

Guest User2025-11-29

Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

These eSIM cards are a great idea. No need to bother with buying physical ones anymore. Have you tried buying and registering a SIM card in the Philippines? Our friends tried, and it took a terribly long time. Overall, if your phone supports eSIM, I highly recommend buying it here. It's less hassle and cheaper.
