Hey I ordered an I'd SIM when i had a Redmi note 3 and it refused to work. It would permanently search for the gateway. 2 months later and I upgraded to the Redmi note 5 hoping it was down to an old ROM on my note 3. However I'm still struggling to register the SIM on this new phone... I saw somebody else on here has no problems with Redmi note 5A.
Am I being a numpty and missing something or do I need to cancel my contract?
