how to send request to GSM Network to check for example prepaid account amount (code like *100#). Is it possible to use Nokia Social Hub? I want to avoid puting SIM card in phone to check my gsm account validity period I would like to do it in Booklet. thx
Thank you offenmeier for suggestion with sms. Actually I found a solution, software is called Logiccode and it can send USSD code like *121# to request prepaid balance. Ussd request is for free, and then I received sms I have to read with Nokia Social Hub which by the way is a disaster in terms of software, sometimes it displays that modem is powered off or no 3G connection even when connection is established.
