I was wondering if anyone has the same or similar problem as mine. I'm using an Mi3W (bought from China) and using it on T-Mobile network in California. Almost everything works fine (including cellular data) except MMS. I'm using my micro sim with an adapter.
A while back I was able to change the APN settings and send/receive mms with Go SMS Pro, but with me not using mms that much, either software update or phone reset lost that settings on my phone and until i realize it I can't seem to set the right APN again despite doing all the thing i remember and newly discover.
I have called customer support and research online and try (I think) everything I can. I haven't tested it with AT&T or another carrier, but since it worked before I'm a bit confused of what I should do. It's not that huge of a deal, considering Viber, whatsapp, and all the texting app out there now, but just bug me a tiny bit when I can't do such a normal function of a smartphone or having to occasionally ask that friend to resend the picture or that group to move to Viber so I can participate.
If anyone has any idea how to fix it or any suggestion I'd really appreciate it.
