I have a Fastrack 1306B with firmware 6.57c and when using the AT+COPS=? command the modem only responds with 1 of the 3 expected operators. When I try this in a Q2686 Dev Kit (the same SIM card),the modem picks up the operators and connects to the home operator.
When trying to connect manually I just get +CME ERROR: 529 (Selection failure â€“ emergency calls only).
I have reinstalled the firmware on the Fastrack but there is no change. When using an older version 6.40 it picks up 2 out of 3 operators.
Does anyone maybe have any suggestions as to why this is happening? I am thinking of getting a firmware version before 6.57 and trying that.
Thanks in advance,
