slow imessage on iphone 5C
I'm trying to diagnose some slow imessage issues. It's very slow on my mother's phone (iPhone 5C), and I've done a number of things to resolve it that haven't helped.
My 'normal' experience - imessage works quickly and has no delays. Example devices I have to compare against are my own and my wife's iphone 5Ss, which send and receive messages instantly, and my brother's iPhone 4S. We are all on the same wifi network at my home, with high speed Verizon FIOS.
My mother's experience - imessage has a blue bar that creeps it's way across the top when you send a message, taking sometimes several minutes to send. Receiving messages also can take anywhere from 1 to many minutes, and she has no idea if imessage will work or not. This happens even when she is at my house on our high speed FIOS wifi. Once in a while
I tried a number of troubleshooting steps, (reset network settings, etc) and finally did a full backup and restore of her phone and then restore from backup (just taken). I guess the next step is to restore without restoring from backup and see if something is interfering along the way. Even after a full restore (and then restore from backup) it reacts the same way - slow creeping blue bar when sending a message, and no indication that a new message is being sent (the wiggly dots when somebody else is typing). I have her phone and mine side by side and I can send and receive to other people instantly, while her phone is slow... both get the same results from speedtest, both using the 'phone number' as the imessage send and receive number. Both iOS 9.2.
The 5C isn't full, it has about 4 GB free (16GB model), so I don't think that's related. I'm running out of ideas. What else could interfere with imessage? We are all using AT&T, and speedtest.net comes up with fast results (25+Mb/min) when I check the cell data connections on both devices. The 5C acts the same whether it's on wifi or cellular (as do all of our devices) - just pointing this out to say that we have good signal strength and speed with AT&T around here - Boston, MA area.
Thanks for any ideas!
