Motorola Droid RAZR M supports GSM network worldwide, still can’t work on T-Mobile or AT&T

There’s a good news for those who have a Motorola Droid RAZR M (XT907), besides being able to work with CDMA network, these phones is also a GSM unlocked devices. So we still can use it even when you are traveling out of the country, such as to Europe or to Asia by using a local micro SIM Card that is available in the destination country.


As we know, if you take any Verizon phone out of the United States you will pay roaming charges that is quite expensive, ranging from 69 cents to $2.89 per minute, depending on where you make a call.

When you enter a Micro-SIM card into the GSM slot for the first time and turn on the phone, it said that the SIM card was from an unknown source, you will notice this notification every time you turn on your device or reboot. The error message is normal and doesn’t affect the signal reception, we can still make phone calls, texting or browsing the internet, make sure you set the network mode to GSM/UMTS.

However, not all GSM carriers can be used on these android phones, if you try to use a U.S. T-Mobile Micro-SIM card, the phone won’t allow you to make a call, even the phone number has been identified in the Phone Settings. If T-Mobile SIM card can’t be used, it is likely that all GSM providers in the U.S. such as AT&T also not supported by Droid RAZR M (XT907) as happened to Droid RAZR HD.
