Hi I'm currently switching to Koodo from bell. I already switched one line and cancelled the one line myself from bell ( didn't port number). But I'm wondering if i was to switch my other line from bell,( phone is still on contract with bell) and port number does Koodo cancel the line with bell? And in turn end the contract? And bell just bill me the final balance on a final bill at a later date or do I need to pay up front?
