Envious of our neighbors across the pond? Unfortunately, a lot of quality phones never make it to U.S. shores, meaning most consumers will never get to experience devices like the behemoth Galaxy Note (my current daily driver, which might come here soon, we just don't know). If you do take the plunge with an unlocked phone, however, it can sometimes take a little doing in order to get it working properly on your GSM network, specifically Internet and MMS. This video will walk you through the steps required on AT&T, with instructions on T-Mobile down below.

Data and MMS APN Settings for Android on T-Mobile:

Check mobile network settings and reset the APN

  1. From the Home screen, press the Menu key.
  2. Touch Settings.
  3. Touch Wireless & networks. Depends on software version
    • Android 1.6: Wireless Controls.
    • Garminfone: Wireless Manager.
    • Behold II: Phone Information.
  4. Verify that the Airplane Mode or Flight Mode check box is cleared.
  5. If you see a Mobile Network check box, verify it is selected.
  6. Touch Mobile Networks.
  7. If you see the following check boxes, verify they are selected:
    • Data Enabled
    • Use Packet Data
    • Data Roaming This will incur charges if you roam internationally, but it is required to receive data when roaming domestically.
  8. Touch Access Point Names or APNs.
  9. Press the Menu key.
  10. Touch Reset to default.
  11. Press the Home key.
  12. Verify the person sending the message does NOT use dashes in the number or saved in contacts. For example: 5552223333 is ok, but not 555-222-3333.
  13. Test your data connection and send a picture message (MMS) to see if it is working correctly.

Checking mobile network settings and resetting the APN resolves the majority of issues, and is much faster than verifying all settings.

Verify and update APN settings

ONLY if the above steps did not resolve the issue, then verify the APN settings:

  1. From the Home screen, press the Menu key.
  2. Touch Settings.
  3. Touch Wireless & networks. Depends on software versionNote: This varies on different software versions.
    • Android 1.6: Wireless Controls.
    • Garminfone: Wireless Manager.
    • Behold II: Phone Information.
  4. Touch Mobile Networks.
  5. Touch Access Point Names or APNs.
  6. If there is a T-Mobile APN, touch it. If not, press the Menu key, and touch New APN.
  7. Verify and update the following settings for the Data APN:
    • Name: T-Mobile
    • APN: epc.tmobile.com
    • Proxy:
    • Port:
    • Username:

    • APN type: OR Internet+MMS (depending on software version)
  8. Press the Menu key.
  9. Touch Save.
  10. In the list of APNs, delete all others that may appear. If there is a FOTA APN, you may leave that one. To do this:
    • Touch the APN you want to delete.
    • Press the Menu key.
    • Touch Delete APN.
  11. Verify that there is a circle next to the one remaining APN to show it is activated.
  12. Perform a soft reset.
  13. Test your data connection and send a picture message (MMS) to verify it is working correctly.
