Other questions regarding this Bad SIM:
After
several CFUN=4, CFUN=1, #reboot when I got CPIN=ERROR the Telit reboots
and sometimes returns a "#STN: 37" string. Do you know why? I don’t
use STIA
Also I tried the STIA command in BAD SIM and it returns (With CMEE=2)
Is this the only one SIM card with problems or all that you have behave the same? What hardware are you using, board/device?
One thing to check and try: fix radio band with:
AT#BND=3
AT#AUTOBND=0
Reboot and check.
I had BND=3 but not AUTOBND=0, I set the commands each time CPIN is SIM Failure and Reboot, when it reboot CPIN is Ready and CREG 1 but after some minutes I get CREG 3
We designed our device for an asset tracking application, we have 80
devices working well but we got 4 that don’t communicate with server
anymore, when we open our device we found that the 4 devices had SIM
Failure, what we did was replacing the SIM
Cards and then the device continued working well so I don’t think it could
be our device, I’m think, the problem maybe is in the SIM Cards.
I have those SIM Cards and I’m testing them I found that with CFUN=4 and CFUN=1 and then REBOOT or even without reboot we got the CPIN Ready but I need to investigate more. The #STN: 37 is a mistery for me, and sometimes the CPIN return SIM Busy instead SIM Failure. I hope it helps.

Luis
All these symptoms lead to the idea that the SIMs are indeed defective in some way, or the is a contact problem in the holder. Are these 4 SIMs different in any respect of the other you have? Do they work in a cell phone?
At the beginning all 4 of the SIM Cards don
Luis, our technical support team asks you to set AT#REGMODE=1 and repeat the test, they are suspecting that is not the real status.
It turns out that in REGMODE=0 CPIN returns SIM PIN and PUK required but in REGMODE=1 CPIN is SIM Failure.
I think that may be the CFUN 4 and CFUN 1 and REBOOT procedure to get CPIN Ready was like a turn around for this problem and we got CPIN Ready for some time and then SIM Failure.
What can cause that a SIM asks for PIN and the PUK?
SIM REPORTING SIM FAILURE in REGMODE=1 y use REGMODE=0 then reboot and this happened.
Module:GM862-GPS
Firmware:07.03.401
SIM card from Telcel(Mexico) operator
CPIN returns ERROR (SIM Failure or SIM Busy)
then CREG becomes 1,3, so I have to CFUN=4 …. CFUN =1 and then CPIN then is READY
CREG then reports CREG 1,2 and then REG 1,1 ….. (after 4-5 minutes) it becomes
CREG 1,3
then I have to CFUN=4 and CFUN=1 to get CPIN READY but CPIN ERROR and CREG 1,3 are back after a few minutes.
Any clue about what is happening?

Any Ideas?
Just a status update on this: our FAE is working to test these SIM cards with Luis, will post news here.
