4G Communication with arduino

Hi all!

I'm working in a security device for my father, he has a motorcycle and he wants to locate it in wherever place in the world, also he wants to turn it off.

I tried sms communication with a sim800l module but I got surprised when the module doesn't detect the 4g chips, the LTE, so I want to know if someone has worked in something similar, I need:

-Comunicate with 4g chip
-GPS localization

I found that there are shields that have GPS and GPRS and can work with 4g but I'm trying to do it the smallest as posible, I'm working with arduino nano, so those shields are very big for my purpose

If you can give me some advice or information about this I will be so thankful!

What do you mean by this?

Interesting project. I can drive only a few mile to find a place where NO cell phone service is available.
