Replying to Getting 4G LTE On My Mac???

So I'm going to be traveling a lot in the next few years, and I'd like to be able to be able to use my computer and upload pictures to the internet, but I'm not sure I'll have access to Wi-Fi while I'm out on my adventures. Anybody know how I can make my Macbook Pro have the capability to pick up a signal like my phone can? I was going to go talk to Verizon Wireless about it considering I have my phone through them, but I want to know a little more going into it.

Thanks for any help ya'll can provide!
