No SIM detected

[bjoern]

I tried to get started with my Berry GPS-GSM. It came with a hologram SIM that I use.

When I try commands like

AT+CGDCONT=1,"IP","hologram"

or

AT+CCID?

I always get

+CME ERROR: SIM not inserted

 

The command

AT+CIND?

returns the following line:

+CIND: 5,3,0,0,0,0,0,0,1,0,0,0

It looks like the SIM is not detected by the module.

I have already tried another SIM that works in my phone, but I got the same result.

Is there anything I can try to get it working?

Hi,

I have the same issue with my boards.

I can confirm that it’s not a board issues, since I tested on 8 different ones. Sometimes, in random occasions after boot AT+CPIN? returns READY.

But on 99% of the cases I receive +CME ERROR: SIM not inserted.

AT+CIND?

returns the following:

+CIND: 5,3,0,0,0,0,0,0,1,0,0,0

Can you provide some assistance please? I have 20 GPS+GPRS boards from you, and I can’t get them out into production.
