Cell Phone Service along Alaska Highway

We kept our cell and MIFI devices off while in Canada. We notified our friends and family just before we turned them off and asked them to send emails which we would check when wifi was available. Turned them back on in Alaska and found good to great Verizon service everywhere we went in Alaska. We even had great Verizon 4G service in Denali. Many parts of the Yukon do not even have electrical power let alone cell service.
