eSIM was easy to installed. I tap on the phone from the order and done in about 3 minutes, activate data roaming and off you go, can access everything from WhatsApp to YouTube. Google in China. Speed outs good and upload is fast. Chew through data a bit.

Reviews: United States 5G eSIM | Full coverage by three networks | Supports ChatGPT | Daily plan/total data | 24-hour billing | QR code
Guest User2026-10-09
I used a US 5G eSIM for 25 days, using 1GB/day. The connection speed was fast, and it worked in most areas except for some parts of national parks. I installed it in Japan and activated it upon arrival in the US. It was easy to use.
