I intend to immigrate to Canada. What kind of mobile phone should I buy? What can I use in Canada?

If you buy all the original price machines, there is little difference between buying them at home and abroad Canada's consumption tax is very high, so it may be worthwhile to buy it at home. If you buy a contract machine, only the confidentiality contract bought abroad can be unlocked (or unlocked by paying liquidated damages) after the contract expires, and the contract machine bought at home also needs to be unlocked before it can be used. If you don't unlock it, your mobile phone won't recognize the cards of other mobile operators.
