Hi Forum,
for some prototypes I recognised that the SIM could not find any network (although “c(g)(e)reg” says “searching” and “at+cops=?” finds some valid networks.
After using the (stalled) SIM in another module, all works again in the old hardware/SIM without obvious reason…
Has anybody else seen this problem? I use SIMs from 1NCE (Europe).
Thanks, Jo
What kind of modules do you use? Can this 1NCE card be used normally when inserted into your phone？
I use BG600L and LTE-M and GSM. The 1NCE SIMS (web: 1nce.com ) are special M2M-cards, not working in phones. But if I insert a “stalled” SIM into another BG600L-module all works again…
We plan to make further tests the comming week.
First you need to determine the insertion status of the card, AT+CPIN?
Then you need to check the antenna connection or replace another SIM card to cross-verify whether it works
Yes, all this was working correctly. Only “at+c(g)(e)reg” did not find anything… I also know from older GSM days, that you must log out correctly each time…
I hope to get some results in the next 2-3 weeks, where we make stress tests with the protos.
I had the same problem on BC66. The problem was that module marks current (only one in this region) base station as “broken” and didn’t connect to it, simply skips.
Try AT+QCSEARFCN
Interesting. But still after changing location by several km the SIM stalled.
However, currently a number of devices is used to reproduce the problem.
So far all are working perfectly…
Hi,
We’ve got around 2500 1NCE SIMs in use in several countries with the BG95. I don’t recognise either your issue or the issue the earlier reply mentioned. Did you set the bands up? Here is our startup script. You should run this only 1NCE (haha)! Normally when you start up the modem you should use the second script. If you keep setting the bands up it will start the network search from scratch everytime.
ATV1;Q0;E0
AT+QPSMS=0;+QSCLK=0;+CMGF=1
AT+QURCCFG=“urcport”,“uart1”
AT+QIDEACT=1
AT+QCFG=“band”,F,80084,80084
AT+QCFG=“nwscanseq”,020103
AT+COPS=0
AT+QCFG=“iotopmode”,2;+QCFG=“nwscanmode”,0
AT+CFUN=1,1
Then just use this when you start up
ATV1;Q0;E0
AT+QPSMS=0;+QSCLK=0;+CMGF=1
AT+QURCCFG=“urcport”,“uart1”
AT+QIDEACT=1
AT+CMGD=1,4
AT+CTZU=3;+CTZR=2
AT+GSN
AT+QICSGP=1,1,“iot.1nce.net”,“”,“”,0
Hi Michael,
thanks a lot! I use a quite similar setup/system (except AT+QICSGP=1,3,“iot.1nce.net” for IP4v6 (the previously used modems SARA R412 (uBlox) worked with IP4v6). But knowing that you have 2.5k working 1NCE-SIMs also helps me a lot. I’ll keep it in focus, the issue only happens very rarely…
Best regards, Jo
