Hello Team,Please how do I set my PC/Laptop EM7565 to work or operate in 4G only mode? I am using windows 10 64bit.I do not want the card to fall back to 3G or 2G.

you can use AT!SELRAT command to set it.

Please can you show me.I am a bit net to this and I am only good with widows.Please kindly show me at least with some video or pictures.As I said I am using windows 10 pro 64bit

If yes, you can use tera term to open the modem port in order to enter AT command
