我有一个verizon razr m，免费给了我。这是一个Verizon模型，但它从未见过网络。 （我现在使用它作为WiFi Android iPod触摸）
我知道CDMA / GSM / 4G和所有这些。但它没有3G无线电漫游？我不需要它才能达到4G / LTE / CDMA，但它会看到3G网络会让我放弃一个畅销的东西。这是可能的，或者这是一个硬连线进入基带，对我没有希望。是否有解锁代码？我是rooting android的新手，但除非我可以刷新基带，否则根本似乎没有帮助。
I have a Verizon Razr M that was given to me for free. It's a Verizon model, but it has never seen a network. (I use it as an WiFI android iPod touch for now)
I know about CDMA/GSM/4G and all that. But doesn't it have a 3G radio for roaming? I don't need it to ever hit 4G/LTE/CDMA, but it would be nice to have it see 3G networks for me to drop a cheapo SIM into when I go out. Is this possible, or is this hardwired into the baseband with no hope for me. Are there unlock codes for this? I'm new to rooting android,, but a root doesn't seem to help unless I can reflash the baseband.
All Motorola phones are unlocked for use overseas. These phones will not work for AT&T and T-Mobile, but they do work out of the USA(I have used one myself)
Turns out, it's a single byte on the phone that determines whether the phone is GSM locked or not. Someone found this, and made a nice tutorial on XDA on how to flip this byte.
The instructions look scarier than they really are. The detail is not because it's complicated, but because they show every single step.
The hard part for me was prepping my Windows box to be able to do this; you need Motorola Drivers and the .NET run-time for the Motorola diagnostic/programming application.
