I'm just kind of taking a shot in the dark here but I've been having an odd problem that has very specific conditions, so here goes..
I am on Aio wireless using a Samsung i9500 with Kitkat. Most of my family are all on StraightTalk wireless.
The problem I have is that my 2 favorite SMS apps seem to somehow have issues getting StraightTalk to download MMS messages I send.
My family members using StraightTalk are able to send MMS messages to me regardless of which texting app they or I use, however, they do not receive my MMS messages if I use the app Textra, or HoverChat to send the MMS. I do not get a failure to send message, the recipients phone just acts as if I have not sent them anything. The thing is, these same 2 apps can send MMS to Verizon customers perfectly fine (I have tested with 2 friends). I know it has to be a problem with these apps as the very same recipients DO get my MMS from the following other apps:
and the default messaging app that came on my phone.
My problem is this.. I have emailed the developers of both apps and tried to explain this but they can't seem to see that there is a problem. (the Textra app dev got me to send a log and the log showed my MMS successfully sending to Aio's MMSC) What I am wondering is, is there anyone else that has Aio wireless and knows someone using StraightTalk that can see if the same issue happens to you? Or does anyone have any ideas what the problem could be and how I can better explain to the developers of these 2 apps so that they may be able to find and fix the issue? I have no idea why StraightTalk would reject an MMS ONLY from a specific app and carrier combination but it is absolutely maddening.
Could these 2 apps be appending some sort of tag or invalid data on the MMS that causes StraightTalk to ignore it and never send the download request to the recipient?
Any help would be appreciated.
