Quectel EM120R-GL Mobile Broadband (cellular) "No signal"


I have a Lenovo T15 with a Quectel EM120R-GL Mobile Broadband (cellular) WAN device that is now displaying “No signal” on the Vodafone UK network after a recent SW update. I have tried updating the driver automatically via the Lenovo app and also manually but the firmware seems to be at a lower version than is recommended in the readme document. The driver appears to be the correct version however the Lenovo service bridge app still says it is out of date even though it says successfully installed.

My mobile broadband was working fine for years before the recent update. Please see the attached screenshots.

Many thanks!
