Data Roaming 2G only

I have just gotten into Shanghai yesterday and my Starhub travel sim only registers 2G network on my phone. I have toggled on and off, switched sim slots and restarted multiple times. My other sim registers 4G, but the starhub does not. It just shows 2G China mobile. My other sim from Telstra AU displays 4G China mobile. What is wrong?


It was working fine in Taipei, Tokyo, Chengdu and Shenzhen, and it literally only stopped working and could only get 2G when I switched off airplane mode when my plane landed into Shanghai from Shenzhen.


Please help

Hi pblade


Do try reinstalling the Prepaid APN using the Happy Prepaid App, switching to another roaming operator manually or placing your SIM Card in another handset to see if this helps resolve this issue as well.


If this doesn’t help, let us have your registered name and Prepaid number by by clicking the red words bracketed by the arrows here > via Private Message < so I can check on this for you.
