#102255 - Query GSM Credit? |
With a GSM module ("modem") connected to your 8051's serial port:
When using a Pay-As-You-Go (PAYG, or "pre-pay") SIM, is there a way to find out the amount of credit remaining? Or even just a Credit/No-Credit status check? I've Checked in GSM 07.07 (the GSM AT Commands Spec) and couldn't see anything? http://www.3gpp.org/ftp/Specs...ies/07.07/ Or does anyone know any little tricks for this...? I fear it may come down to just having to stick the SIM into a phone, dial the Service Provider, and listen to the anouncement. :-( |
