I’m using the AT commands as described at the http://support.sodaq.com/sodaq-one/at/.
All commands give OK but with AT_CSQ the only value I get is +CSQ:99,99.
AT+CGATT? gives +CGATT:0 in stead of 1 if it is connected to the T-Mobile network.
Using +CGSN I’ve checked the IMEI and this can be read so the SIM card is visible.
What does this mean?
That T-Mobile has no coverage in my area or can I do something else to make this work?
