EP06-E doesn't fully support UK networks

IoT Modules LTE-A Module

I’ve been trying to get the EP06-E to work with VOLTE on UK/GB O2/VMO2 network so that the module doesn’t drop to 3G mode on calls.

ATI
Quectel
EP06
Revision: EP06ELAR04A05M4G

It appears I need a new firmware with the UK carriers mbn files for this to work. Is one available please? If not how do I tell the module to stay in 3G mode instead?

Thanks

Hi ,
AT present, EP06-E European authentication only uses Deutsche Telekom operator authentication. If you want to lock the module network in 3G, run AT+NWSCANMODE command
