I use a T460s with a Google Fi SIM card in it running Debian. It works really well and Google lets you get up to 10 free data sims so you don't need another account.
If you are a project fi account holder, you can get an additional data sim cards (up to 9) to put in devices like iPad, other tablets, or in this case the laptop. It will be linked to your main account and share the data budget of your main phone, at the same rate of $10/GB.
Tell me more. What exactly do you mean by "up to 10 free data sims" ?
