I have a 3g Blackberry - will it work in the US?

Hi David

It really depends where you are. A 3G only phone will work in some areas. If you need a reliable phone, you should have a phone with LTE capability.

Please check here for compatibility requirements with the Fizz network: https://fizz.ca/en/faq/compatible-devices#2

It should work, using mobile data might just be slower.
