Un-Lock all your phones for new customers(and current), for a trial period to see if your product speaks for itself - Pricing / Data Charges(plans) Customer service / Web site and ease of location. I think you will find that you will not lose many customers with having the phones unlocked at the time of purchase. I paid for mine to be unlocked, I haven't left and don't plan on it. Trust your customer base and I think you will be surprised. Everyone I know that uses Koodo refers it to friends and I don't here complaints about it except, have phones locked.
