Running Android with data functionality from a laptop with a SIM card slot

I have always worked with laptops and amnt a fan of smartphones or tablets, But I will soon be required to use an app, which doesn't have a desktop alternative, meaning I will need an Android-capable device. So I was thinking could I run Android off of a desktop and as I will also need my SIM card from my cell phone, I was looking at the Lenovo ThinkPad X250 as it comes with a SIM card slot. And I know Android can be loaded onto a laptop using the likes of Bliss OS or Android x64 But I have read that people have had issues with connecting to the mobile data from the SIM card when using Android this way and was wondering if anybody knows any good ways to accomplish this.
