Problem 1 → When I attempt to send an sms message with AT+CMGS"phone number" I recieve immedaitely error CMS 350.
Problem 2–> I am unable access the internet . I am getting the ip from network provider but anable get the ipaddress.
Problem 3—>ATD9874561231; is giving no carrier.
can anyone help;
The correct text-mode syntax is: AT+CMGS="123456789"
The modem must first be in text-mode, with: AT+CMGF=1
What does AT+CGPADDR return?`
Is number 9874561231 capable of accepting a data call?
For what purpose are you trying to establish a data call?
