Garmp, It's going to depend on a few things. First, who do you have your cell service with? You may have data available using the phones and plan you already have.

You can buy a mobile hotspot from a second tier vender to use if you wish. Straight talk and others that sell pay as you go services may be an option, pay for a month and let it expire until you need it again, and then get another month. Re- activating can be a hassle with some.
