Hi all.
I have been messing around with a couple of GSM modems. One is a Telit and the other a SIM300.
With a Vodafone sim I can enter the command:
AT+CUSD=1,"*#103#"
and I get the network time back. But with t-mobile, virgin and orange sims installed I cant get this command to work. It just sends back:
CUSD: 4
So, my question is how come I cant sent such commands with the other networks. All i really want to do is get the time. I thought such codes were universal?
Thanks
Trev
