Once you receive your new phone, you will have to register the device first before use. Registering your phone will program the device on your wireless carrier's network. Many devices arrive unregistered, just in case the package is lost or intercepted by someone else. Registering your new phone is simple to accomplish online or over the phone with a representative.
Visit your wireless provider's website, and create an account, if you have not done so already.
Log into the account, and click the link to activate a new phone.
Remove the battery from the back of your new phone and locate the ESN, IMEI or HEX numbers.
Return to the online from, and fill in the required information. You may be asked to create a security code as well.
Enter your IMEI, ESN or HEX numbers into the appropriate fields.
Enter your e-mail address, and select the option to activate your device. Follow the on-screen prompts to continue registering your phone onto your wireless carrier's network.
Remove the battery from the back of your phone, and write down the ESN, IMEI or HEX numbers.
Dial "611" from your new phone, and follow the prompts to speak with a customer service representative.
Inform the representative that you want to activate a phone. Verify your account, and provide the representative with your phone's ESN, IMEI or HEX numbers.
Follow the representative's instructions to complete the activation process.
Charge your mobile phone fully before you register the device.
