I wanted to know if there exists any method to check currency balance using AT commands or getting balance value as an sms reply so that it can be parsed later. I'm using an Airtel sim.
Unfortunately I'm unable of mind reading. Telling what you already did generally helps to get a specific answer.actually i did search over, and even tried AT+CUSD=1,"*123#" but it didnt work.
The shown syntax is correct so far, the service command itself is just passed to the provider and not checked by the modem, it won't give an error if not understood by the provider. But mobile phones are not necessarily implementing the full AT command set, +CUSD is flagged optional in 3GPP TS 07.07, that's all I can say in this regard.I guess phone or SIM300, both work the same way!
