Error message when texting on Ericsson K750i mobile
tmuncey hello,
Sometimes because of a phone bug or a SIM error, the "Service Centre" for SMS messages is changed.
Please call your cellular Service Provider, and ask for their SMS Service Centre settings.
Then, go to Messages > Settings > Text Message > Service Centre.
Make sure the number you were given by the Service Provider matches the one written there.
If not, please changed to the one given to you by the Service Provider.
