So while I wait for AT&T level 3 support to look into this and get back to me, thought I would see if anyone else has seen this issue. I had my original S4 stock rooted since it came out and never had an issue. Night before I was traveling it starts rebooting randomly and when I wake up the next morning it was dead. I was sent a refurb S4 (MF3) and again rooted it, did my usual Titanium freeze of same bloat as previous phone. Things were fine for a week and then I found out I could no longer send or receive MMS. I get an error that it is expired or not available. Spent a few hours on the phone with support, they had me change sim card (I just used my sim with replacement phone instead of the one they sent with it.) That did not fix it. If I power the phone off and back on I can usually get 1 MMS before it fails again. Did a factory reset, it worked for a few test MMS they sent and then stopped working. So they sent another refurb phone. I get it yesterday (MF3 again lucky me) and root it, didn't freeze anything and test it. Everything is working good for a few hours, sent and received like 20 pics to verify it. Then after a few hours, I can no longer send/receive them again. Internet/data works fine on the phone when the MMS issues happen. The MMS issue occurs whether sending or receiving from/to all 4 main US providers so it's not provider specific either.
APN is the default. They say my account is fine. The other 2 phones (S4 and S3 both not rooted) on my account work fine, though they are in a different state than I am. I tested while I was out running errands to make sure it wasn't a tower issue. Tech support provisioned my phone again several times. At this point I am out of ideas. Multiple sim cards and phones and the same issue. Doesn't make sense to me that power cycling or factory reset usually fixes it for a few minutes to an hour and then it stops again. So far they haven't made me go to a service center. Have a feeling if I go there they will try and blame it on being rooted when that isn't the issue.
Any ideas of what else I can try while I wait?
