Want to use your data service on your HTC Droid Eris while roaming? You have to enable it, because by default the setting for data roaming is disabled.

1. From the Home screen, press Menu.

2. Tap Settings.

3. Tap Wireless controls.

4. Tap Mobile network settings.

5. Check the Data roaming checkbox.

Careful with this setting though. You could incur some major charges if you’re in certain areas or your mobile plan is expensive when roaming.
