In a news article we gave at the beginning of this month, we mentioned the roaming incident that plagued a T-Mobile G1 user abroad. This user closed the data roaming application in order not to pay too much, but on the invoice that came later, he saw that this feature worked and returned to him as an extra cost because he did not realize it.
T-Mobile has made a statement on this subject In a statement, he stated that some G1 applications sold in the Android Market automatically turn on the data roaming feature. There is no problem as we are not using T-Mobile G1 at the moment, but if you use an Android device in the future and you are going abroad, we will warn you in advance: Uninstall the programs that automatically turn on the data roaming feature before you go abroad!
