Hello,
I am a 35 year old academic, wanting to explore the world of tech some
more. So the task I have set myself is to learn how to build and
program a mobile phone (only for calling and SMS over a GSM network).
I am in uncharted territory, so I need your help please.
Ideally want to run the phone over a LTE network.
I had a look at some part from your website, but need some guidance
please on what I need.
I observed this product, would this be suitable?
I want to go down the road of Raspberry Pi, but I am open to Arduino systems as well potentially.
Best regards,
Owen
