with FREE MOBILE (a French operator), I am not networked.
to solve this problem, I had to change the settings of the card, I chose 3G as the preferred network instead of 4G. there, the sim card works but I no longer enjoy the 4G.
why the phone does not automatically switch between 4G and 3G? with this operator.
with another operator (BOUYGUES TELECOM) I do not have this problem, the phone works in 4G and automatically switches to 3G when needed. |
