This may seem like a no-brainer but you never know. My husband and I have two phone lines/numbers billed under one monthly Koodo account. We are considering cancelling my line and keeping his as he really wants to keep the phone number. We don't want to close the monthly account, just cancel one line. I opened the account and my line first, and his line was added to the account about 30 minutes later. There are no phone purchases involved. We brought our own equipment. Can we drop my line without in any way affect the other line's plan rates etc.?
