I have been with Verizon for a long time and I am grandfathered in to their unlimited data plan. However, I understand when I upgrade my phone (which will happen soon) I will lose the unlimited plan. Sprint offers unlimited calls, text and data (guaranteed as long as you remain a customer) I am thinking of switching to Sprint but wanted to understand how their coverage is for travelers. Anybody out there use Sprint and are you happy with their service during your travels?
