Very easy to find and the SIM card signal is great. I didn’t even use hotel wifi haha, simply used this SIM card for my entire 5 day trip!

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.

Good SIM card. The internet was perfect in Beijing and Hong Kong. There were a few issues in Guangzhou and Chongqing.

An absolute must-have for frequent travelers. Constantly swapping physical SIM cards at every new airport is a massive hassle and a waste of time. This eSIM service eliminates all that friction—you just land, activate, and get connected instantly. Highly recommended for anyone who values efficiency.

Perfect for people coming to China. Easy to use, convenient, connects to the internet and works fine, not too slow.
