I have an HTC Desire HD (unlocked) purchased in Australia, currently operating on a T-Mobile network but I am not getting any data service. I purchased an activation kit from Amazon and the $30/mth unlimited data package from Walmart. Text and voice are working fine, but I am not receiving any data.

The data plan is a 4g plan but I assumed that would also include 3G for those without 4G phones.

On the phone settings, T-Mobile is listed under settings > Wireless & networks > mobile networks > Network Operators. When I select Network Operators > Select Automatically it flashes up a message "registered on network".

Is there something I must do to get my phone to work here? OS = Gingerbread.

  • Check for your APN settings - found in Settings > Wireless & Network settings > Mobile Networks > Access Point Names. – t0mm13b Jul 22 '13 at 18:23
  • Thanks. I found some APN settings on the T-Mobile site, and it is working, but very slowly. – david004 Jul 24 '13 at 6:28

You can't. The "international" version of the HTC Desire HD is not hardware compatible with T-Mobile USA's 3G frequency bands. The phone's antennas support HSPA on the 900 and 2100 MHz frequencies (the North American GSM variants should work, though: source), and software settings will not have any effect on this. T-Mobile's 3G network uses:

  • 850 MHz: Acquired via a roaming agreement as part of the failed AT&T merger
  • 1700/2100 MHz AWS: the device must support both of these frequencies to work because the 1700 band is used for uplink and the 2100 band is used for downlink.
  • 1900 MHz

As you can see, these do not line up (excepting half of the AWS band, which is not sufficient). You'll need a new phone if you want 3G service. See Can I use my device on a different carrier? for suggestions on how to determine which phones will work.

  • Thanks. I think you must be approximately correct. I am receiving very slow internet after changing my APN settings as indicated above. Cheers. – david004 Jul 24 '13 at 6:15
