AT&T User - MMS not working

Alaskan — Sat, 02 Jun 2012 01:55:52 GMT

I bought an unlocked Xperia Pro for use on AT&T's network. I have the data working but can't get the MMS to work. I have been in touch with both Sony & AT&T and both just point the finger back to the other.

I have tried the following Access Point settings unsuccessfully. Are there any AT&T users out there who can assist me? Please?

Name: AT&T

APN: wap.cingular

Proxy: leave blank

Port: leave blank

Username:WAP@CINGULARGPRS.COM

Password:CINGULAR1 (yes this is in CAPS)

Server: leave blank

MMSC: http://mmsc.cingular.com

MMS Proxy: wireless.cingular.com (also tried 66.209.11.32)

MMS Port: 80 (also tried 8080)

MCC:310

MNC:410 (note: this could also be 310, 41 or 15)

APN Type: leave blank (also tried internet+mms) (also tried mms)

Yes, as I stated in my original post, my data works fine. It is only the MMS which is not working.

do you keep it enabled or do you turn it off once in a while?

Meaning the data? If so, I always keep it on. I am a very heavy data user; I have an unlimited data plan.

Excellent ( so do I) but anyway, I'd noticed that I get issues like this with att and the way to solve it is to delete the APN -> re-enter it and if you have a LOT of SMS/MMS it will start to act up.

Okay, I will try to delete all of my APNs and re-enter this one. Thanks much for the advice. I'll let you know how it goes.

Yes, I wondered about whether that might help. I haven't checked to see if my number is up yet. I have only used Android about a month and am finally getting the feel for it. I figured if I jump to ICS, I'll have a new learning curve.

I don't know when it'll be released for the "a" variant, but you can manually update it

Hooray! That worked! I deleted all my APNs including this one, then re-entered just this one and BOOM, my MMS is now working (and data is still fine). I am so grateful to you, uliwooly. Thank you very very much!
