Note:
– Before connecting to IP make sure to:
• Enter APN settings by AT+IPGPRS command detailed in Section 2.1.1 on page 17.
• It is suggested, after modem power up, to wait for about 20 seconds before initiating a IP connection.
– When reading +IPCONNECT, the command may answer +IPCONNECT: 1,3, this means the modem is still
trying to connect. Please wait a few seconds and check again.
