MC7750 and `CME ERROR: SIM wrong` with various SIM cards

Legacy Legacy AirPrime modules
1

I have following mPCIe modem in a PC Engines APU3 device:

ATI
Manufacturer: Sierra Wireless, Incorporated
Model: MC7750
Revision: 33, SWI9600M_03.05.10.13ap r6237 cnszxd00000132 2014/04/18 16:55:52
MEID: **************
ESN: ***********, **********
IMEI: ***************
IMEI SV: 1
FSN: *************
3GPP Release 8
+GCAP: +CIS707-A, CIS-856, CIS-856-A, +CGSM, +CLTE1, +MS, +ES, +DS, +FCLASS

…and I cannot make it connected to the network.

I tried with various different firmware versions, different SIM cards, from different providers, without success. I’ve tested also those SIM cards on different LTE modem and those SIM cards work there and I am able to get the Internet on that other modem with the same SIM cards.

AT!SPN?

AT+CPINR
+CPINR: SIM PIN,3
+CPINR: SIM PUK,10
+CPINR: SIM PIN2,3
+CPINR: SIM PUK2,10

I’ve also tested with Orange Poland. Any idea were could be the problem?

OK

Could it be hardware issue on the sim slot pin from modem?

4

Have you resolved this problem?

5

What is the problem you have right now?

6

Same problem as Topic Starter.
I have mode that can’t start network registartion.
AT+CPIN? return SIM wrong.

7

I also have MC7700 and this module work perfect in same configuration.

8

How many different sim have you tested?

9

No. I did not manage to resolve it and I tested different SIM cards and also different modems (non Sierra Wireless), with the same SIM cards and problem is only with Sierra Wireless modem.

10

I think three. Also tested SIM cards on Huawei modem and no issues with Huawei modem. Problem is only with MC7750 modem.

11

FYI, I’ve also asked in different thread is my modem locked in any way at Is my Sierra Wireless MC7750 locked in any way?

12

is it same issue with older firmware?
