Firstly, you may be in an area where there is no data coverage. Data isn't available when you are roaming onto the coverage area of one of T-Mobile's network partners and it is also not available everywhere where T-Mobile have their own network.

If you're in a major city and still can't access data on your phone, then you may need to update the APN settings on your phone in order to access data.

Around 98% of mobile phones will automatically configure themselves for T-Mobile's data network. However if your phone cannot access data you can manually change the APN settings.

Apple iPhone

If you have an Apple iPhone go to Settings > General Settings > Network > Cellular Data Network

From the APN field, enter internet2.voicestream.com (if that doesn't work try wap.voicestream.com or epc.tmobile.com)

Leave the username and password fields blank.

Android phones

If you have an Android phone (such as an HTC Legend):

  1. On the home screen, press MENU, then Settings > Wireless & networks
  2. Then go to Mobile networks > Access Point Names
    on the APN (Access Point Names) screen, press MENU and tap New APN
  3. In the APN field, enter epc.tmobile.com (if that doesn't work try internet2.voicestream.com or wap.voicestream.com)
    Leave the username and password fields blank.
  4. Press MENU and tap Save

If you have a BlackBerry:

  1. Click on Options (from the home screen)
  2. Select Advanced Options > TCP/IP
  3. Enter epc.tmobile.com where it asks for the APN and leave the username and password fields blank. If epc.tmobile.com doesn't work, then try internet2.voicestream.com or wap.voicestream.com
