Lemt 2.2 just bought, need advice on messages

Hey guys, nice to meet you all.
I need a little help, I bought the Lemt 7.1 4g 32g
I’m somewhat tech savvy, is there a way to send messages on the watch Via bluetooth to my note 9 phone ?
It seems I cant do anything with out Wifi or Sim card installed ? I can receive messages but cant reply.

Advice… ?? How do I use my phones internet connection to use the features of the watch with out buying a separate Sim…

One more question can I use a SD card in place of the nanoSim card slot…

Please help and thanks
