unlocked sidekick 4G texting problem (messaging center)

Hello everyone,
First of all, I have a sidekick 4G that I unlocked through a unlock code website. And the sidekick is running on AT&T with Edge and talk (receive and send) working flawlessly.
The only problem I have is that I can receive text messages, but cannot send any.
So I went ahead and called Samsung and they suggested that the problem was my messaging center number, so I followed their directions and did this ,MESSAGING->MENU BUTTON->SETTINGS and scrolled down to messaging center only to find it greyed out.
I have the latest update and did a factory reset and what not.
My question is how do I set the messaging center number from the one Tmobile set to AT&T 's messaging center number?
Please help! I don't want to have a unlocked phone that cannot send text messages!

Call AT&T and ask. Or ask a friend that has an Android. The number should be the same. If you can't get it to work then you can always download an app that gives you a number for texting, i.e. Google Voice, textfree, etc.
Look in the settings of your previously used phone you had for AT&T. The number should be there. If not, ask a friend. If not, then you can call AT&T. I believe numbers differ according to region, based on a quick Google search.

I have the number, its just that the field where I enter the number is greyed out, meaning I can't configure it. Are all sidekicks like that?

Go to settings wireless n networks mobile networks Then access point names then click on tmobiles apn and edit it or add ur own apn the best is to copy it from another android on att u can just go to the store and copy it from there floor modles the line for the texting is the mmsc line

Ok, so I just got it, and I tried it, with sending messages still not working. I called att and I asked them what was the problem, and they suggested that my sim card might not be working correctly, so I got a brand new sim card and surely enough, texting worked!!

Phone won't download pictures from messages

I've had a rooted phone for at least a month now, and no matter what rom I've used, my phone refuses to download any pictures or videos people send me. I've ran cm7.1 and now I'm on existz' ics, and I was wondering if there was a patch to fix the issue or anything like that.

Can you tell us what steps you have taken to try and save the pictures/videos?

Is your data on when you try to download. Usually pics and videos are mms messages which must use data even if your on wifi.

I'm not seeing where its possible to access these settings, whether I'm just not looking in the right spot or the rom doesn't have that option

Dude when you get to "Access Point Names" click it. There you should see three APNs
1 ATT
2 MediaNet
3 MediaNet mms
If there is no # 3 then just hit menu and new APN and create one
Tap on # 3 and it should look like this
Name: MediaNet mms
APN: wap.cingular.com
Proxy: blank
Port: 80
Username: [email protected]
Password: CINGULAR1
Server: leave blank
MMSC: http: //mmsc.cingular.com
MMS Proxy: wireless.cingular.com
MMS port: 80
*MMS protocol: WAP 2.0 (if there is an MMS protocol spot)
MICC 310
MNC 410
Auth type: blank
APN type: default,supl,mms
APN protocol: IPv4
Bearer: unspecified
Maybe cwhitney24 or zelendel will come along and make corrections.

the MEdia Net MMS APN. and everything is entered exactly.
Currently running on Inspire4g
ROM - DIESEL POWER EDITION ICS
Kernal - LorDmodUE-9.8.8-ICS-CFS

Do you have your data turned on? To download a picture message it takes alittle bit of data to do so, but att doesn't charge for it.
.

I do have data turned on and wifi off, I was able to download MMS before flashing the Rom, I tried a fresh install also but no luck.

It might be an issue with the ROM itself...I cant remember if diesel how MMS works in diesel edition...check out the ROM thread and see if any others have the same issue. Or try finding a different APN settings, other than the ones you mentioned above.

According to "Whats Working" in the Diesel Rom thread SMS/MMS is working, I've tried just about every APN setting I can find and when I search the thread no one has an answer btw I don't have the "MMS protocal:" field in my APN settings, I don't know if this is an issue.

I just finished installing the new update to the rom "It's Been A Pleasure" and it seemed to fix the problem for me. Thanks for all your responses. I truly appreciate it.

Telus MMS

I just got my 8X and everything is working except MMS. I put in the APN settings I could find but apparently its not enough. The messages show up but I can't download them. The settings I am missing are...
WAP gateway(URL)
WAP gateway port
And what I should put in the maximum mms size. I think its 300 for that. I also need to know what the best IP type I should choose. Thanks.

T-Mobile Nexus 5 APN

I use Hangouts and now and then my MMS gets backed up. I recieve late messages in group chat and the MMS sometimes doesnt even go through.
I looked at the APN settings and there are 4 different choices.
fast.metropcs.com
epc.tmobile.com
fast.t-mobile.com
fast.t-mobile.com
I can always add more. Does anyone know of a good apn that works?!

on t-mobile it's fast.t-mobile.com
the metropcs one is obviously for metropcs.
epc is an older apn, which may work but I don't think is optimized for LTE
For MMS your problem is likely not the APN
but the MMSC, MMSC proxy and port settings
or it could just be poor reception when your sending the MMS

With this, is it better to use the ipv6 or the ipv4?

I've wondered about which one I should use for a while now. To be honest, I haven't noticed much of a difference between the T-mobile APN's available. Or all of them for that matter... What does everyone think is best, or use the most?
NEXUS 5

I use the MetroPCS one the most sometimes MMS doesn't work on the tmo ones
