I have this phone sm-a750g AND AM ON T-MOBILE. I cant make or receive calls, I cant send or receive text messages. The only way I can send or receive txt's is I have to add a picture and when it converts the message to MMS I can send it and to be able to receive a txt the sender has to do the same and add a picture. If I try without the pic it tells me it will send when the service becomes available. I've tried several different APNS to no avail. When I try to make a call it tells me i'm not registered on the network, I try to register on the network and it tells me t-mobile isn't available even though it finds it. I can get on the internet just fine with the phone and browse email and social media just fine. I've been with customer support for hours and days at a time to no avail and of course everything is tip top on there end and it has to all be me. I can put a att or cricket sim in and everything works fine?? bad thing is im not on anyone of those carriers. SOMEONE PLS HELP ME BEFORE I GO FREAKING CRAZY OUT OF MY MIND!!!!!!!
Hello,
just for the usual text messages: have you changed the setting for using text-Messages?
Messages > Settings > Chat Settings > "Select default messaging type" > Text/multimedia msgs
With the chat option I've allways had some problems here.

I'm on the AT&T network and can't send texts anymore after flashing to ICS. I can make calls and use my data plan but am unable to send SMS for some reason. I've tried almost every APN setting recommended by others and still nothing. Does anyone have any suggestions or has had a similar problem that they resolved?

Correction. I can receive text messages but not send them.
*UPDATE 9/11*
So I found out the issue is related to the Message Center which you can access from "Messaging" -> hit the option button -> Settings.
After flashing to ICS I noticed that this option has been removed so I can't edit the message center. Are there any ICS or JB ROMs that still have this option available to the user? I need to change the message center number back to what it needs to be in order to send SMS texts.
27 views and no responses? Anyone?
After a BUNCH of research I finally found out how to fix this. Instead of posting a to the thread I found (since I'm still under 10 posts) I will post my copied instructions.
Go to google and search for your SMS center number which should be based on the carrier you have.
Next, go to twit88.com/home/utility/sms-pdu-encode-decode
Scroll down to where you see SMSC, Receiver, and Alphabet size.
Put in the entire SMSC number, including the + sign into the box, leave receiver blank, change the Alphabet size to 8, and delete whatever is in the message box under Alphabet and hit Convert.
Now, on your phone go to the Phone info menu described above and scroll to the bottom and find the SMSC field.
Enter the first 16 numbers into that field and hit update.
Reboot your phone and you can now send SMS.
This fix is for people who have the proper modems flashed on there phones and can still receive texts but not send them.
I was wondering if any of you with straighttalk reading this with an ATT Samsung infuse with the att sim could quickly hit *#*#4636#*#* then under phone settings scroll down and look for the smsc line and hit refresh and write down and post it for me.
I have been using straighttalk for the past couple of months and suddenly I don't have SMS anymore I can't send or receive. My phone does say message sent but no one is receiving it. I've tried deleting my messages, factory reset changing the smsc to the AT&T settings different messaging apps and I cant get it. Customer service says the problem is ony end but I'm not sure how it is from night to morning without any changes.
I'm running Scott's. 2/3/2012 build
** I am able to call and use the data
After several hours of troubleshooting and a hard reset, I've been told that the reason I am unable to SEND picture messages is due to a incorrectly configured "Short Message Center" number. All other functions (make/recieve phone calls, send/recieve text messages, browsing the internet, and recieving picture messages) work fine.
I have verified the APN settings are correct, and supposedly everything looks good on the carrier's end but I'm still not able to send picture messages. The carrier (Solavei, an inept T-Mobile reseller), expected this to be displayed after entering a code into the dialer app, but instead displayed on the most recently called number. (The code was *#*#4636#*#* which did not work). Any ideas on how to set this on the Motorola Atrix 2?
Android Version 4.0.4
Sys Ver 67.21.125.MB865.ATT.en.US
Forgot to mention that using another carrier's (Cellular One) SIM card on this unlocked phone with the correct APN settings is able to succesfully send/recieve picture messages on this phone, and that I am able to send/rec picture messages when using my SIM in another phone.
Update: I am able to send MMS messages using a 3rd-party app (Go SMS Pro), with a custom-set MMSC, which matches the MMSC in the APN settings. Does anyone know how this works?
Also, does anyone know if the ROM I used when flashing my phone could have known issues with particular MMI codes, (as apparently suggested HERE: http://forum.xda-developers.com/showthread.php?t=737594)?
Does anyone know how to remove the call back number on every single sms message I receive? Even if the person has it turned off on their phone it still shows up on mine when they send me a message. I would just use another messaging app because that fixes the problem but then I can send mms messages. I'm on a local carrier and can't find the settings to put in to fix this either. Any help is appreciated thanks.
*can't send mms I meant to say.
As the title states. I am using the settings that where sent to the phone and when I try to send a txt it pops up a box telling me when there is an internet connection it will send it but it never sends. The internet on the phone works just fine, can browse all day. PLS HELP, I have 60 days to return the phone and if I cant send or receive txt or mms then its no use to me. The soon I get it figured out the better. Can anyone share their APN Settings for T-Mobile..
FIXED.. NOT!!!! Thought i had it fixed.... anyone use this on T-Mobile need help PLS..
