Just the other day we reported that a user was charged a ridiculous amount of money for data roaming when his data was turned off, even after being assured that he would be ok. It appears that this has caught T-Mobile’s attention and they have come fourth with an official response.

The option to turn off data should work fine, but that’s not always the case as any third party application can then override this basic phone feature whenever it chooses. This then brings us back to the initial problem of not being able to kill background processes on the T-Mobile G1.

From the horse’s mouth: “Some third-party applications available for download on Android Market require access to the internet and have the ability to turn on data roaming when in use. Customers are informed whether an application will use this feature prior to downloading, but should also be aware when traveling outside the country.”

Official T-Mobile statement:

T-Mobile is committed to delivering the best experience in wireless to our customers. If a T-Mobile customer would like to use their T-Mobile G1 while outside the country, they should contact Customer Care before they leave to ask that the WorldClass feature be added to their service at no additional charge. If they choose, customers can also disable data roaming on the G1. This can be done by going through the following steps: Home Screen > Menu > Settings > Wireless Controls > Mobile Networks > Data Roaming.

Some third party applications available for download on Android Market require access to the Internet and have the ability to turn on data roaming when in use. Customers are informed whether an application will use this feature prior to downloading, but should also be aware when traveling outside the country.
