In order to make it work we had to equip our boat with high speed, reliable Internet access. All marinas claim to have WIFI Internet access but in most cases, it is not reliable and not high speed. You are sharing the Internet access with all of the other boats in the marina, so you are at the mercy of how much bandwidth is left. Deanna is on her computer, with video and teleconferences every day, so dependable Internet access is a must.
Although most US cell phone companies offer cell phone coverage while you are in Mexico, the amount of data that you can use is limited and adding extra data to your plan when you run out gets expensive fast. One better alternative is to purchase a WIFI router and a monthly data plan from a local cell phone company just as you might do back in the US. Obviously, this only makes sense if you plan to be in the same country for an extended period of time.
This option worked well at first, but we found out soon that we were limited in how far from town or our marina we could travel. We had to be close in order to have a strong cell signal, otherwise we were out of luck.
