We have several 4G routers with these modules. The newer ones are fine but older units fail to connect using vodafone simcards. Could it be I need upgrade the fw of the module. No release notes I could find. Pse send me the latest firmware so I can find out myself.
Kind regards
Hi @stacker007
Note that this version has a rollback feature, so you will not be able to go back to the old version after upgrading.
Hi, you mean no rollback feature i guess
