Not sure if it's mentioned anywhere on the forum and I didn't want to create a new thread just for this but I just got the $55 Koodoo MB/SK plan which is pretty much equal to the $65 plan that Fido is offering but I'm only paying $49.50 a month (-10% BYOD).
1. Walked in to FS and told them that I'm moving to MB and need a local number so I won't have to go through the trouble of getting a plan there once I arrive.
2. FS gave a MB number for the $55 unlimited 5GB data (-10% BYOD).
3. Registered account online and ported my local 604 number via Self-serve
4. Profit! I'm now able to make calls using my old 604 number and receive calls to my 604 as I would normally.
