Question about Microsoft Windows Vista Ultimate Edition
1. When USB modem used with one sim card it shows MIN out of range please contact your service provieder.
2. When USB modem used with another sim card it shows 721 error
please tell me the solution of both the problems
Just learnt that Windows has a Hyperterminal through which you can send commands to the USB devices. But the problem is the call centers will not tell the MIN. They just ask to bring the product to their place, which is not possible for a self-employed person. You can change the MIN using the Hyperterminal if you know the value to be entered.
One solution is to read the data using the AT commands from a friends' MODEM and write the same using AT command to your MODEM. This should work if your friend is in the same area as you are in.
