What's to know about Fizz before moving lines there?

Fed up with Virgin hiking up my plans every few months. I need calling, text, and some data, at a reasonable price for two phone lines. Wifi calling would be great as I'm surrounded by concrete. I've narrowed it down between Koodo and Fizz based on bring-your-own-device plans and coverage.

My biggest concerns are

• chat-first support (chat only? I don't call often but some issues are just resolved easier over the phone)

• porting over existing numbers (not a deal breaker to get new numbers but would be nice to keep existing)

• coverage in Ontario and Nova Scotia

All the good, all the bad, would love to it.
