How to Activate a Used Boost Mobile Phone

By Maya Austen

Boost Mobile is a wireless no-contract pre-pay phone service offered by Sprint. To take advantage of Boost Mobile's wireless phone services you don't necessarily have to go out and purchase a brand new Boost Mobile phone. If you have an old used Boost Mobile phone, that will work too. Before you can activate the phone, however, there are a few things you need to know, for example, the phone's 15-digit IMEI number, as well as the 15-digit ID number printed on the SIM card you plan to use with the phone.

Step 1

Purchase a Boost Mobile Starter Kit. This kit as of December 2010 is available for less than $20 on the Boost Mobile website (see Resources for link). If you have an old Boost Mobile SIM card, in addition to a used Boost Mobile phone, you may not need to purchase this kit. You can use the old SIM card, but without the kit you will have to pay a $10 reactivation fee.

Step 2

Turn off the Boost Mobile phone. Remove the battery cover from the back of the phone and take out the battery. Write down the 15-digit IMEI number or the 18-digit MEID number (labeled "DEC") printed on the label inside the battery compartment.

Step 3

Open the SIM card cover located within the phone's battery compartment. Gently push forward on the currently inserted SIM card and lift it out. Avoid touching the gold colored areas of the SIM card. If you plan to use this same SIM card when activating the phone, write down the 15-digit SIM ID number printed on the back of the SIM card.

Step 4

Take out the SIM card from the Boost Mobile Starter Kit (if you plan to use a new SIM card with the used Boost Mobile phone). Avoid touching the gold colored areas of the SIM card. Write down the 15-digit SIM ID number printed on the back of the SIM card. Also write down the PIN activation number.

Step 5

Insert the new SIM card from the Boost Mobile Starter Kit, or the SIM card you just removed from the phone, into the phone's SIM card compartment. Make sure the card's gold contacts are facing down, and the clipped corner of the card is positioned on the bottom left. Close the SIM card cover. Reinstall the phone's battery. And put the battery cover back on.

Step 6

Contact Boost Mobile Customer care at 888-BOOST-4U to activate the used Boost Mobile phone. Or go online to the Boost Mobile "Activate Your Phone" Web page (see Resources for link) to start the activation process. Have your credit card ready in order to make any required payments.
