Not having the same error, but my texts come across as BLANK. No sender, no message, nothing. Any clue what could cause it?
Seems after my phone (curve 8330) it'll either work fine for a while or instantly start doing it again.
I removed the battery from my phone while it was still on, and then inserted the battery back into the phone. It has been nearly a full day without any problems. Before doing this, approximately 50% of my text messages resulted in "SMS errro 4". So far, so good.
Did this help? I asked about this at a Sprint store and they said they had no idea what was causing the. They suggested wiping my phone and reinstall the OS. That's crazy, if you ask me.
Powercycle the phone.If you're sending the text messaging from contact list check if there is 1 added to the phone number or not. Check if you can manually enter the phone number and send the text message. Also, call TechSupp to check if there is any sms provisioning issue/block issue or sms orgination issue.Finally perform completed reset with techsupp.
