Almost everyone in Belize has a cell phone. The cell coverage here is pretty good. However the whole country is experiencing Internet problems right now, so we can't say it’s a full proof plan by any means.
Cell phone service in Belize is on a pay as you go basis. You can buy a prepaid card and load the amount to your sim card or you can just top up your cell phone at any store. On average, i spend about US $50 a month for my cell phone. I make a vast number of calls because I use my cell phone for work. So $50 is a lot if you compare the amount others who do not use their cell phones as much as I do spend.
We also use Skype, Viber, or GoogleTalk as other means of communication via Wi-Fi. You do not have to pay anything extra for using these applications in addition to your existing Wi-Fi.
