T-Mobile APN Settings

If you want to access Internet on your smart phone, you need to set it up via APN (Access Point Name) settings so that you can surf the web, retrieve email, and send multimedia messages.
APN is the data network that your Internet-enabled handset access to get onto the Web. This guide shows you how to setup your T-Mobile APN settings on Android and iOS in the US. Note that settings change slightly depending on country where T-Mobile operates.

Android is a hugely popular mobile operating system and chances are you’ve used at least one version of the system or might use one in future. However, getting your Android-powered handset onto the Web is not always straightforward. There are specific settings you need to configure on the T-Mobile network so that your handset can receive data packets. Unlike the usual phone settings, APN settings are hidden a little further into the handset, so you need to dig deeper. Here is how:

  • Open the main menu list or applications list.
  • Select ‘Settings’.
  • Select ‘More Settings’ or ‘Wireless and Networks’.
  • Select Mobile Networks.
  • Tick the ‘Use Packet Data or Mobile Data’ check box.
  • Select Access Point Names.

T-Mobile APN SettingsSave the settings to the handset and create a new connection for data packets. To do this, go to ‘Menu’ and select ‘New APN’. You’ll be presented with multiple fields in which to enter the details of your mobile data network. Fill in the T-Mobile APN details as follows:

  • Name: T-Mobile US
  • APN: epc.tmobile.com
  • Proxy: 216.155..165.050 (you may leave this blank)
  • Port: 8080 (you may also leave this blank)
  • Username: (leave blank)
  • Password: (leave blank)
  • Server: (leave blank)
  • MMSC: http://mms.msg.eng.tmobile.com/mms/wapenc
  • MMS Proxy:
  • MMS Port: 8080
  • MCC: 310
  • MNC: 260
  • Authentication Type: (leave blank)
  • APN
  • Type: default, sulp, admin, dun, mms
  • APN Protocol: IPv4/IPv6
  • APN Roaming Protocol: IPv4/IPv6

iPhone (iOS)
Like Android, you can setup your iPhone manually so that it can work on a data network. Here is how you can setup your iPhone on T-Mobile’s data network in the US.

  • Go to ‘Settings’.
  • Tap ‘General’.
  • Tap Network Cellular data.

Enter the following settings
Cellular data: epc.tmobile.com
Username: (leave blank)
Password: (leave blank)
MMSC: http://mms.msg.eng.tmobile.com/mms/wapenc
MMS Proxy:
MMS Max Message Size = 1048576
MMA UA Prof URL = http://www.ipple.com/mms/uaprof.rdf

And that’s it. You now have a fully setup handset and the only thing left is a test. Go to your home screen and open the browser to see if your settings have been saved and activated. If you’ve filled in the settings correctly, your browser should load a web page without problems. Otherwise you need to check your settings again or reset the handset.

When you need to troubleshoot your APN settings, be careful not to mess them up because your data may be used by apps, thus leading to unexpected data bills. If, for some reason, you messed up the settings, go to your phone’s ‘Reset Settings’ to delete and reset afresh.
