Wireless service rates are not regulated. Service providers can charge you when switching your telephone number to a different service provider, and these fees can vary by service provider. Also, keep in mind that when you change service providers you may have to buy a new cell phone that is compatible with their wireless network.
Before switching, ask about local and long-distance call plans, because companies may have different billing practices and rates. For instance, you may not be able to your landline phone's long-distance plan and you may need a different plan or a different arrangement to make long distance calls.
Whenever you change service providers, you may still have a contract with your current service provider. Check your service agreement to find out whether you’ll have to pay any penalties for switching before the end of a term.

Some of your phone features may be interrupted while your phone number is being transferred, but you should be able to make and receive calls during that time.
When you’re switching your number from one wireless provider to another, there should be no disruption to your 911 service. However, when you’re switching from a landline to wireless service (and vice versa), your 911 service may be affected. Ask your new service provider what level of 911 service they provide and any limitations that may exist.
