INSTALLING A SIM CARD FROM A DIFFERENT CARRIER.
I'm currently in Africa, Uganda.
Sad to say but I'm unable to install any sim card from the Mobile Carriers of the region.
When I try to install a sim card, a notification pops up telling me that the network is blocked and that I have 0 times left to unlock it.
I have tried to take it to different technicians, only to fail.
Wondering whether there is a way I can do it differently?
My device is AT&T Trek HD(K88), 7.1.1 android version.
