I have a new Huawei P20 phone, into which I have put my contract O2 nanoSIM. I can call and use LTE but can't send any text messages.

I have set the service centre number to +491760000443 and still no luck.



Can anybody help me please? 🙂 thanks in advance!
Hi Lobster28,



do me a favor and switch off 4G on your device and then try to send an SMS while you are in 3G networks. Does that work?

Dear Nicolas,

I turned off 4G and now my texts send.

What should I do now?

Thanks!
Hi @Lobster28,



thanks for testing, this was helpful to find the right solution.

I reconfigured you SIM-cad registration.

Please turn 4G back on, restart your phone and test again in 4G ;-)



Kind regards,



Emanuel
