We will be traveling for 3 months next year in Canada (Motorhome). I already know that our phone service will not work there (Boost). We will need some internet to keep tabs on business. Is there an air card that you can use for 3 months that will work in Alberta and BC ? Or can we buy an air card and just subscribe for 3 months? Or some kind of pay as you go air card? Thanks in advance for your help, Janet
