swap sim

[Lisa22]

I received a new phone and Sim, I have inserted the sim but I cannot receive or make phone calls or receive text messages. When I try to register my sim is tries to send me a text message which I can't receive.  Any ideas on a way forward please?

Thanks

You need to do a sim swap using the old sim
