recently I bought a 3G shield from elecfreaks. In that I tested AT commands for calling related and camera and SD card related operations. But while trying to send email I got network error. can anyone please help me to solve this problem. below are the commands I used to send email and the replies from sim5216E modem.
I recharged my sim card with 3G internet pack.
And I tested the 3G frequency of modem (UMTS 2100 MHz) with the frequency we are using for 3G network in INDIA. Both are same.
Please help me to solve this.
