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.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

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.

Using this 5G eSIM on my i16 Pro in Busan was generally quite smooth. What's particularly noticeable is that my friend, an Android user who switched to a Korean SIM card, didn't have as stable a network as me. Overall, it was smooth, with occasional stuttering when browsing Shopee or other websites, but calls and LINE were fine. 👍
