Every time a itry and send , the message goes to a status of sending and then fails. I have had a another person try and sms with the SMS , the message are no making it to my service.
I have done all teh know work arounds of manual networ selection and clear data , restarted . Still no luck .
ANy Idea here
Maybe a bug in the stock SMS software. Try another app. Then people try deleting the cache and old SMS data for the SMS app, in Android application manager. Then they try a phone "hard reset" which deletes a lot of data, and you have to redo your phone.
You can also try another cheap phone, to see if it's the SIM.
Be prepared to accidentally lose all your contacts and SMS, unless you have backed it up somewhere.
