Waze can only function as well as the 3G/4G cellular data reception you have. In Eastern Canada, Bell seems to be an ideal carrier that gives strong 3G signals for Waze on almost every major highway, even through remote areas. Meanwhile, cheap carriers like Freedom Mobile's miserable reception barely allows Waze to work. I recently tried T-Mobile on I-90 in NY and New England. In most parts I have only cellphone signal ("E" for EDGE, aka 2.5G) but no 3G/4G signal. This renders Waze basically useless. So I did some research: Which seems to indicate that Verizon is the best carrier for using Waze on highways. What's your experience and recommendation for the best US cellphone carrier for Waze?
