Will be staying at a relative's house for the next month. There is no internet access at the residence. I will not trade every day, but I want to have access available in case I need to or want to do so..... Is the only thing I can use a Verizon wireless EVDO card? Do I need to have a Verizon cell phone plan to use it? Is there anything else I can do in this situation as I would only need the access for about a month. Any ideas???
