cell phone

Years ago driving I paid $15/mth for Verizon access in Canada, towers were limited. You may/may not have access in the Canadian ports. Actually the same for US ports depending upon your provider so check with them.

Suggest you just enjoy the cruise and leave the phone in the suitcase. Arrange for emergency communication if that is your need. We passed many bus loads of happy cruisers headed to the cruise line resorts without a clue as to what they were missing. Or perhaps they wondered why we missed so much?...

I would not expect any phone to work. Distance from the few cell towers, if the tower serves your network, & mountainous terrain is going to severely limit any service.

You might get service near the ports but don't count on that either.

The good news is that it is actually possible to survive without a cellphone in your pocket. It was done before.

What Crowe said. Keep in mind that there is also the issue of international coverage / charges while in Canada / Canadian waters, depending on the specific route of your ship.

Never done the complete traditional inside passage but have done a good chunk of it in pieces. Although some of those segments were several years ago now, cell towers were pretty few and far between. If staying in touch is important, based on my most recent trip in early 2020 (before the panic set in), I'd recommend a Sat phone.

Call the cruise line and ask. Whether or not it works has nothing to do with the state the phone but whether or not there is access to cell towers along the route, which is unlikely. There is usually the option of renting a satellite phone if you wish to stay in touch with reality.
