if you deactivated your rogers account before porting the number, you may lose your previous phone number, if you ported the number while your rogers account is still active, i don't see any issue. if that's the case, pm the moderator team..
I got my and my parents' SIM cards from the mobile shop, no need to wait and they offered free activation service. I ended up active them myself. But it's great knowing that in case anything goes wrong, there is someone who can help.
