Scenario, steps to reproduce

This same code works using a SIM7600 module , only changing #define TINY_GSM_MODEM_SIM7070 to #define TINY_GSM_MODEM_SIM7600. Change define is enough to make the script stops to connect to my server. Its connect to operator network.

Expected result

The expected result is to get the GPRS connection and send the data as the SIM7600 does.

Actual result

When I switch to SIM7070, I can access the GPRS network using modem.gprsConnect but I can't connect to the server using client.connect code. So I can't do the GET command to send the data.

I think the log is not correct but it is attached
