Hello,
I just got the iPhone 4S last night and up until this point it has been working great. I am able to send and receive iMessages to other iPhones and to receive texts from non-iPhones, however my phone will not SEND sms texts to non-iPhone users. Any suggestions or anyone else with this problem?
Update: Just in case anyone else has this problem - soft reset didn't work, however, *228, option 1 updated the service area and got it to work.
You are not alone. I've just randomly started getting this same problem
I have an iPhone 4s running OS 5.1.1. It has worked perfectly since October 2011 until about 2 weeks ago when I suddenly stopped being able to both SEND and RECEIVE text messages. When I send a Text Message, I get a "Message Send Failure." People attempting to send me text messages receive no warning that it did not go through.
iMessages are not affected. I can send iMessages to other iOS users.
What I have tried to do to fix the problem, but with no luck
1) Disabled iMessages completely in an attempt to avoid the "is the other person an iOS user?" check
2) *228 option 1 (reprogram your phone)
3) *228 option 2 (update your roaming information
4) Cleared all Network Setttings (General/Reset/Reset All Network Settings)
5) Restored phone to from a backup
6) Restored phone to factory default
No luck whatsoever.
This issue roughly corresponds with the activation of my wife's iPhone 4 a few weeks ago. I would hardly say it is the cause, but the timing is suspicious given the changes to my wireless plan and the activation of a new device.
