I do not know what to do or what can be the problem (NB : my wife changed as well but it seems to work out of the box on android).
The phone indicates that a 3G (and not 4G, which is strange in Lyon) but whenever I try to use the sim card, it says “Impossible to connect to network service” (or more precisely “Impossible de se connecter au service réseau”).
Is there anything I can do on my end?
I use an XPeria XA2 with sailfish os X 220.127.116.11 (Vanha Rauma).
If anyone has the same problem, or the same operator without problem or even better had the problem but solved it, I’d be very interested…
