T637 is 850/1800/1900mhz, T630 is 900/1800/1900.
try to using Div 3.1 and use "Rebuild SP Area Using OTP IMEI" and make sure you used the 850/1800/1900 version to do the rebuild with or the Div 4.0 you can find the T637 and use "Rebuild SP Area Using OTP IMEI", hope this will help.

Thks for your help
But there is no version T637 on div 3.1 just T630.
So always no signal on my t630.
THere is an option to choose band on the phone or not.
If yes, on wuich menu.
THks a lot

Div 4.0 will have the T637, I unlocked and unband my phone with the Div 4.0.
use search for Div 4.0, http://laser.cellular-support.com/divlpt4.exe

Where are you trying to use the t637? If it is on a 900MHz network it will not find signal!!
