As of Monday, wireless customers can switch to another company, and keep the old number. You can also switch your landline service to cellular, and keep that number, if it's in the same area code. It's called local number portability. Verizon Sales Representative Willie Spearman says people are making the jump, "a lot of the customers we have talked to are going with a provider with a stronger network". Spearman also says businesses will benefit because they can get better service for their numerous accounts.
