Procedure for Activate the Sprint Phone
Remove the back cover from the phone you want to activate. You will need the numbers located on a sticker under the battery later on.
Call Sprint customer service. The phone number is (888) 211-4727.
Follow the prompts given to be directed to someone to help you activate your phone.
Speak with the representative. The representative will walk you through activating your Sprint phone, including asking you for the specific numbers on the inside of the phone. If you do not currently have a Sprint wireless plan, the representative will give you the different plan options available for your phone.
Conclude the activation. Once the activation is complete, you will be able to start up your phone and you should receive a signal immediately. The representative may ask you to boot it up while on the phone still just in case any troubleshooting is needed. The activation charge and any other plan changes/activation will show up on the cell phone's first bill the following month.
