Which kind of application do you have in mind? Do you have access to a USSD gateway?

If you do have a gateway, you can look at an example rapidsms ussd app

https://github.com/unicefuganda/rapidsms-uganda-ussd

if you just want to run ussd commands on your modem , checkout

I modified a version of rapidsms+pygsm to add USSD functionality a
while back. Not sure if it will take care of your needs, but i'm happy
to help with any questions.

Basically, I added a little function to the gsm backend:
https://github.com/ewheeler/rapidsms-core/blob/master/lib/rapidsms/backends/gsm.py#L139

And added a run_ussd method to gsmmodem.py:
https://github.com/ewheeler/pygsm/blob/master/lib/pygsm/gsmmodem.py#L441

Here is an example of some USSD functionality implemented as a
rapidsms app: https://github.com/ewheeler/rapidsms-ussd-app/blob/master/app.py#L147
This code allows you to check the balance of SIM cards in the gsm
modem, load credit from scratch cards, and transfer credit to other
numbers.

Please don't hesitate if you have any questions!
Best,
Evan

I think its simillar to the one you've developed... the thing is, i dont have a gsm modem... my idea is to start developing ussd app and 4 that i need to learn how to do it and be able to test it.

Hi Evan

This looks really similar to a project that I would like to do - send questions via SMS to participants, wait for a response, and then transfer small amounts of credit to them if they respond. It looks like this code will work for any country, but just wondering about the different networks.  In Ghana, there are like at least 4 major networks and I'm worried that I can't send credit from one network to another. 

Have you implemented this code in Ghana by any chance or know someone who has?

Thanks!
