Motorola A1200 T-Mobile Settings
I could have sworn that I posted this a while ago, but when I told someone to look for the information here on this site he informed me that I was wrong. Oops.
It’s quite simple to get the Ming to work with T-Mobile’s data network in the US:
- Start the setup app (normally under Home->Extra, but this depends on the theme that you use)
- Scroll down and click on “Data network” (almost at the bottom)
- Click the menu icon and “New”
- Name the profile to your liking (how about “T-Mobile”?)
- Leave GPRS settings blank
- Set APN to wap.voicestream.com
- Leave User name and Password blank
- The default Timeout of 15 minutes works for me
- Primary gateway IP is 216.155.165.50, Port: 8080
- Secondary gateway IP is 216.155.165.51, Port: 8080
- Select DNS server and fill out the following two servers
- 216.155.175.40
- 216.155.175.170
- CSD setting dial in number is +19132440821
- Don’t select Query at Logon and leave User name and Password blank again
- Baud rate is Auto
- Line type is Modem
- Timeout once again 15 minutes
- Same DNS servers as above
- Click Save and you are done
Now whenever the phone tries to open a data connection (for example when you use it as GPRS/EDGE modem for your Mac), T-Mobile will be one of the options presented to you.
The settings above have worked for me for more than a year now - and once you have enabled the EDGE hack you get pretty decent throughput!
Thanks for visiting!
I hope this was helpful - if not, please leave a comment and let me know why! Were you searching for something else? Did I miss an important aspect?

On the Motorola a1200….I followed your directions. I can connect to T-Zones fine, I can send and receive text and was able to send an MMs but I cannot receive MMS and I can pair with a bluetooth device but other devices cannot pair with mine. Are there other setting I need to adjust?
Thank you so much for your help

You can send a test mms to 222, then try to recieve a mms. If it fails, it’s most likely a software limitation with T-mobile networks; the phone is not fully compatible with T-mobile. It several of those a1200s that came from China have an issue with mms, either sending or recieving.
I am having issues with a motorola ming I purchased from ebay. I have tmobile and can connect to tzones, but when I try to download I get the error code MNFE. I have contacted tmobile and motorola which was no help. I think this phone was a bad purchase. I also can’t send or receive pictures. These are the 2 biggest problems so far and I have only had the phone for 2 days. Please HELP ANYONE. mccollistern@yahoo.com
