My roommate's iPhone 5S on Sprint. When iMessage is turned on, he can't send or receive messages to non-iPhones since the iOS 7.1 update.
He tried rebooting and resetting network settings... neither did the trick. If iMessage is turned off, SMS/MMS works fine.
I also have a 5S on Sprint, and I don't have this issue after updating.
I noticed that too after I updated my iphone 4 and iphone 4s to iOS 7.1 on March 10th. I cannot send any mms pictures to other kinds of phone like android. Iphone to iphone mms picture works fine. Regular text works fine to all except for picture messages to android phones. I called up my carrier and was told to contact Apple directly because of the iOS update. You're not alone.
I have the same problem ... I am on an MVNO of AT&T (H2O Mobile), and because of that my iPhone imediatly configures the network to run off of AT&T's settings. Whew you use the SIM Swapping trick to make changes to the MMS config Apple's software overrides the settings back to those defined by the built in carrier profile. In my case I am using a factory unlocked iPhone 5C, and I cannot make the changes needed to make the phone work properly with the carrier's MMS system. Apparently Apple's idea of unlocked means slightly less unlocked from the carrier locked version, but still locked up tight.
According to the Apple CS person I talked to. It turns out that the settings were reset during the new OS update (which contained version 16 of the AT&T carrier settings), and the SIM Swapping settings access exploit was locked down because it posed a major security threat. I will post more if I hear anything else.
Thanks, but that has nothing to do with iPhones officially on Sprint.
The phone on Sprint. Could the problem be with Messages. If it is you can try calling Apple's support line and get they might be able to fix the problems with the on-line database for Messages.
Hi,
One additional thought, Have you tried logging out of iCloud on your phone, rebooting your phone, then logging back into iCloud. I do that when I have syncing issues with my calendars. As per my previous post I bring up the Messages iCloud issue because someone at Apple brought it up as a problem, but it wasn't the problem I was having.
Thanks
