Has anyone tried USSD/GSM/MQTT service yet?

Hey guys,

I’ve just come across the USSD based services such as and From what I’m reading it sounds like it might solve a lot of hassles that I’m currently experiencing with using TCP/IP and MQTT, namely different coverage areas for different providers, trying to manage airtime over different devices etc.

Has anyone actually tried these services in real life, and what were your findings?

Thanks a lot!
