Wanna make a brief test in your razr?
1. Type in dialpad
2. In the menu that appears, choose phone information
3. Navigate to SMSC and tap >update< (at your right)
The blank space shoulde be populated with Mobile Service Center number.
If you get an [update error] message that means your radio and sim chip are not compatible (happens mostly with older sim cards, cutted ones) if so, you have 2 options: wait for another driver 4.0 ICS, or buy a updated micro sim chip. (there is a third option often does't work, but - call carrier support, ask Mobile Service Center Number, set itt in blank space and type first left update. It's a bug and rarelly works)
If this was helpfull, please share the learnigs.
