Gotta remind folks that you won't have cellular service or internet in many areas in northern BC and Yukon, and Alaska.
Along the Alaska Highway, Dawson Creek, Ft St John, Ft Nelson, Watson Lake, Whitehorse and Haines Junction have either 3G or 4G service.
Teslin, Destruction Bay, Beaver Creek have only CDMA service and you'll need a CDMA compatible device to be connected. We deliberately purchased older technology smartphones so we could use them in all the communities.
On the Klondike Highway, Dawson City has 4G service. The rest of the communities-Carmacks, Pelly, Stewart River-have only CDMA.
There is no service between the communities along the highways.
For the Cassiar Hwy, there is no service between Smithers BC and Watson Lake YT. There is one small service area along Hwy 16, west of Smithers, but the Cassiar Highway has absolutely no cellular service.
