RedteaGO Esim for China Mainland working pretty good!
Bought a esim for Mainland China before arriving, I am coming from Mexico. The buying process is smooth and simple, I did it one day before coming. As soon I landed in Beijing Capital airport the activation took seconds and could inmediatelly enjoy 4G service, all services and western apps (WhatsApp, X, Instragram, etc) operates perfectly as in my home country, I got a notifications storm after spent so many hour in the air haha. The connection has very good stability and quality, as there is no lag or sudden loss of coverage. You can enjoy normal signal coverage indoor and outdoor, and even connects to 5G like a local sim. 4G is pretty good enough. I suggest you configure in your phone the low data mode over cellular and configure your apps to save data usage by reducing video auto-play or high quality photos, it will help you take more advantage of your esim data package, the data plan will be consumed as much as you use it, but these tips can help to have the plan for longer time Make sure your phone supports esim and is operator unlocked. After arrive here, I tried to configure an esim for a relative on an iPhone bought in China and is was not possible, as China iPhone version does not support it. and those situations are out of the control of the esim provider. In conclusion, Before coming I decided for a small data plan (10GB) thinking maybe the service experience wont be good and I will loss the money, but I am really surprised about the RedteaGO esim data service quality, in past trips to China I used to have a VPN but with this esim data service is not needed anymore and can have data all the time, without need to ask for WiFi (VPN needed again !!). While I am sharing my personal experience in China, I think for other countries service experience will be the same good !
