Message not sent, service not activated

[Lindsayh]

Hi

I have a s22, and can send short text messages SMS, if they are longer they will not send, and it says message not sent, service not activated. I've called my network, they said its a handset issue?

check the message center number,
old style sms messages need to be send to there and it differs by network provider, you can ask your simcard provider for their number
