$30 - $250

Project Description:
I'd like a tool where I can send bulk SMS's and USSD commands. I need specifically to know the balance of a prepaid phone, the flow is the following:

1. I send an sms to the carrier

2. Carrier responds with an USSD screen asking me for my PIN.

3. I enter the 6 digit PIN in the USSD screen

4. Carrier delivers me the balance via SMS and USSD

Is there a way you can automate this? I need to do all of this from my PC.
