Psn verification code is not arriving?

Hello people I no longer get a verification code via SMS? Yesterday everything worked out perfectly normal today just no more SMS to anyone knows what I can do? Unfortunately I don't know the replacement code

Then I would really best call:

"Call us on 06102 771 3001

We're glad to help you. Service times: Mon to Fri 10:00 a.m. - 6:00 p.m.

Depending on your request, we need either the information for your PSN account or the serial number of your console. Before you call, please make sure you have this information ready. "
