Official Sierra Documents/Firmwares (May require free Sierra account).Now the problem seems to be that I cannot access the Rain network, which operates on 2.6GHz (2600) using my EM7455 card.Have a question/comment? Please use the Community Discussions instead of opening an issue.ĮM7565/EM7455/MC7455 - Modem Configuration Index Removing that SIM and inserting the Rain SIM resulted in CME ERROR 13, SIM failure.ĭoing an AT!RESET, and waiting for the modem to enumerate again allowed me to verify that the Rain SIM was now recognised, and that it was able to get my subscriber identity from the SIM. My original Vodacom SIM was recognised this morning when I opened my laptop. I have also upgraded the firmware to the latest version I could find, being SWI9X30C_02.30.01.01_Generic_002.045_001.zipĪt least with the AT commands provided I could verify whether the SIM was identified or not. This is on a Thinkpad P51 running Ubuntu 16.04LTS, if that makes any difference. I have removed and reinserted the SIM, and checked repeatedly that it is the right way up, etc, etc. That would also explain why I was unable to register with the Rain network, if the SIM could not be read.Īny suggestions as to how I can verify that this is indeed the problem? It seems to me that the SIM or SIM card reader is the problem, as I get the following error message from the sudo qmicli -p -d /dev/cdc-wdm0 -dms-get-msisdnĮrror: couldn’t get MSISDN: QMI protocol error (37): ‘UimUninitialized’ Worse, now when I put the original Vodacom SIM back in the modem, it also cannot register with the network! I tried 3 different SIM cards, and was unable to register with the network. Recently, I got some SIM’s for the Rain network, which operates on LTE Band B7 2600, to my understanding.
I have an EM7455, which I have been using successfully on the Vodacom network in South Africa.
