Text message failure after SIM swap

[GDavies]

Good morning - my father was sent a replacement SIM for his Nokia 6131, the old sim was working fine but O2 advised it would stop functioning on April 1st.
I helped him do the Sim swap and all seemed fine but he his now unable to send text messages..
Have called customer services but they have been unable to resolve and are sending out a replacement sim.
Two questions: is the Nokia 6131 flip phone compatible with the network still?
If the message centre is incorrect will the sim adjust it to the correct centre number?
Any other advice welcome.

The sim should be the correct type for the account.

PAYG and contract sim cards are different, so ensure you get the correct type.

It will be printed on the sim packet.

Thanks for your answer, do you have any thoughts on the message centre question please, I’ve a nagging thought it might be the problem...

@GDavies 

The number is set by the sim, hence having the correct sim type.

For customers on the PAYG the message centre number is +447802092035.

For all other O2 customers, the message centre number is +447802000332.
