I have updated a Galaxy A53 to a A55 at the earliest date possible. My Wife has an old Galaxy J5 (2016), which is on an ID SIM only deal. I returned my A53 to factory defaults and transferred the data etc across to the A53 OK. When I add the SIM it comes up with a SIM not allowed message . Could this be due to the fact that the A53 has not come to the end of contract yet?

SIM is not allowed

Hi
Our devices are unlocked and you’d be able to put any SIM card in the device at any time, there wouldn’t be anything on our side stopping you from putting another iD Mobile SIM only plan into it.
Is it being used in SIM slot 1?
It may be worth trying a replacement SIM card, which can be picked up from any Currys store and activated here.
