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.★

The best coverage. Excellent connection and speed. Easy setup without a bunch of settings. Thank you! We were always connected. Video format doesn't lag either. I tried a continental SIM card, but nothing worked. With a global eSIM, everything is absolutely simple. I highly recommend it to anyone who has an eSIM-compatible phone. The assistant support is also excellent. I love TripCom.
