Has anyone noticed any red flags with the flexibility to switch Airvoice plans depending on the month?
For example, in the summer, I conduct a lot of field work and my employer will reimburse $20/month for cell phone use. So most of the year I'll use the $10 Airvoice plan but then for a few months each year I'll want to bump up to the $30 unlimited plan and then drop back down in the fall.
I would think this should be a seamless switch but I currently have AT&T and they try to charge fees every time I want to switch. I usually end up going down to the closest AT&T and just ask them to switch. If they won't do it, I'll try another time and another employee will it do it in about 10 seconds. It's a pain but I've been able to avoid the fees.
