Is there anyway to tell what companies provide coverage in an area? We live in a remote area in Mexico and our access is horrible, 2G via a cell tower and a Huawei E1756C stick. Because I am not fluent in Spanish it has been impossible to talk with the local companies to find out what will work. My neighbor signed up for a plan and when they got home neither the cell phone or internet stick could pick up a signal. I am so frustrated!!!! Jodie
