<html><head></head><body><div>Hi all</div><div><br></div><div>I'm trying to understand some principals of the SIM connection methods of OVMS.</div><div><br></div><div>Reason is that I recently moved from "the big city" Munich to the very much rural village Thalham. In Thalham we have so called "lite" mobile transmitters. These transmitters are installed, as far as I understood, to safe money and to prepare the transition of the providers to 4g / 5g. They are forcing the frequencies towards the 4g band with those.</div><div><br></div><div>So these transmitters seem to offer only 2g and 4g, but no more 3g (really ???).</div><div><br></div><div>I don't have any network connection with the SIM in my OVMS here in Thalham. In the next village Zolling I have connection. In Zolling they don't have the "lite" transmitters, but still have full 3g support. The antenna of my OVMS is working well (-100 dBm to -70 dBm).</div><div><br></div><div>Now my questions ...</div><div><br></div><div>Does OVMS have a fallback on SIM5360 Europe to 2g (EDGE) if 3g is not available?</div><div><br></div><div>I also did some reading in the modem documentation and tried to send some AT commands. Goal is to try to force the SIM into 2g mode. I tried i.e.</div><div><br></div><div>simcom muxtx 2 AT+COPS?</div><div><br></div><div>to get some information from the SIM, but I don't get an answer on that command at all. No matter what channel I try. Am I missing something there?</div><div><br></div><div>Thanx for input.</div><div><br></div><div>Regards</div><div><br></div><div>Chris</div></body></html>
