You can do it!!!
Seriously, the easiest is if you feel certain you have Verizon coverage ... that is likely pretty straightforward plug and play. Actually, same if you KNOW you have good Sprint coverage. The only reason, in my opinion, not to go for the BYOD plan is if you are uncertain about the quality of the coverage since you do not want to worry about troubleshooting. (I understand!)
I ultimately ended up with the Verizon MiFi plan and have it hooked to a directional antenna. We have that antenna primarily to keep the signal steady and it now gets regular 4G. Depending upon your coverage, you may not need the extra antenna or an amp.
Good luck and have faith!! LOL It's worth it, I think, to get better service.
