Most importantly – do not cancel your service with your current carrier before contacting your new provider. You won’t be able to port your number if it has been deactivated by a carrier (or at best it will be really difficult to)
Before porting your number, you need to decide which plan you are going to switch too. Use the WhistleOut wireless comparison search to decide which carrier and plans fit your monthly needs.
Once you have decided which carrier, plan and cell phone you want to go for, contact your new provider. They will ask for your name, address and customer account number as they appear on your bill. They may also ask for your account password if you have one. Most carriers will allow you to set up the number porting as part of the online activation process. Its really easy - we have tested a lot of carriers in this way.
If you want to keep your device, you may also need to provide your phone’s ESN/IMEI number, which is usually located on the back of your phone or under the battery.
Your new provider will then contact your current company and start the porting process. You do not need to do anything else, just wait for your new service to start. Usually this only takes a few hours, often its done within 30 minutes so you hardly lose any service.
Once your new service is activated, your existing service should be automatically cancelled – however, we recommend giving the company a call to finalize the transfer (and perhaps negotiate any termination fees or other charges). You will usually receive a bill for any outstanding debt within a month.
