Verizon Nag

[msgdew]

notification says not verizon sim in sim1, how do I get rid of the nag; have 3rd party in phone and works fine so guess unlocked. Also is there an app like devcheck was in s21. thx

Sorry to say you will have that message until you put a Verizon sim back in the phone since you are using a Verizon Phone some sims will work and cause the error message

But the phone is supposed to be unlocked.

[GaryB82]

What's the model number does it end in U or U1

[msgdew]

It ends in U

[GaryB82]

Ok that's a carrier version so only way to get rid of that message is to have the phone reprogrammed to your new carrier which a service center would need to do. U1 Is factory unlocked and can be used on any carrier since they don't have carrier software installed

[msgdew]

Can it be flashed with U1 firmware, my previous S21 was also verizon and unlocked and I didn't have this problem

[GaryB82]

Yeah it can be flashed with U1 just be careful doing it

[msgdew]

OK phone is fully updated so would I use a original U1 firmware or the latest one, thx

[GaryB82]

I would use the newest version but I've never done it myself
