Enabling data roaming
Connect to your mobile operator's partner networks and access data services when
you're out of your mobile operator's coverage area.
Using data services while roaming may be costly. Check with your mobile operator
for data roaming rates before you use data roaming.
1. From the Home screen, press
2. Tap Mobile network, and then select the Data roaming check box.
Select the Data roaming sound check box if you'd like HTC Thunderbolt to play a
sound so you'll know when it's connecting to a roaming network.
