Hi,
I am planing to create a program that will do folowings
- check validity of SIM card
- Check current balance in the SIM card
- Recharge SIM card using some top up cards.
SIM card can be in mobile phone(Say it Nokia), May be in a Modem(Siemens and Wavecomm)
Please suggest some options, How can i do that.
Regards,
Vijay Shanker
