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.
