First of all, the specs: I have a new Motorola Razr M (build date, Mar 22, 2013), running Android version 4.1.2 (Jelly Bean)
The issue is with sending group messages, or messages as a part of a thread involving multiple recipients (who all happen to have iPhones), through the native text messaging app. The app makes it clear that these are sent as multi-media messages, not text messages. However, the messages don't seem to be sending. Instead of the "sent:" timestamp at the bottom of the message, there is perpetually a small green arrow. (There may also be a delay in receiving messages in this thread, but I'm not sure, as the senders are on the other side of the country.)
Others who have encountered this problem (according to the vast archives of the internet) have figured out that MMS are sent via the carrier network, so through 4G (or 3G), which seems to be true. The messages send without a problem when Wi-Fi is switched off.
So the problem seems to be that the phone isn't properly switching to (or recognizing the need to switch to?) 4G to send the message when it's already on Wi-Fi.
Anyone have any ideas about how to fix this issue (other than rebooting the phone)?
Can I force my way around the issue by manually configuring the settings so that Wi-Fi switches off when the messaging app is open, or something equally clever?
