If you bought your new phone from the carrier’s store, then it most likely came to you activated. If you bought your phone used or had the carrier ship it to you, then chances are you’ll need to activate it. The process is a little different for each carrier, but this wikiHow article will guide you through the basic steps to get your phone activated with any carrier.

Easiest Way to Activate a Cell Phone

Log into your carrier’s website, select the line you want to activate the device on, and enter the IMEI number for your phone. You can find the IMEI number by dialing *#06# on your phone. If you’re having trouble activating your phone online, call your carrier or visit a retail outlet for further assistance.

  1. This may not be required during activation, but it can be helpful to have around. [1]
    • Dial *#06# to display your new phone's IMEI. You can also usually find it printed on your phone's packaging.
  2. Most carriers have activation services that are available through their websites. This can be a much quicker method than trying to call and get a cell phone activated.
    • The process is slightly different per carrier, but generally you will need to log in, select the line you are activating a device on, and then enter the IMEI number for the phone you are activating.
    • If you're activating a prepaid plan online, you will likely need to enter an Activation Code. This is typically included with your SIM purchase. If you don't have one, you'll need to call the number below for your carrier, or go into a retail store. [2]

  3. If you are having difficulty activating online, or have a special case (such as activating an upgrade received from someone else's line on the same plan), calling your carrier will be the easiest way to ensure that everything activates properly. [3] You may need the account holder's SSN or other identifying information.
    • AT&T - (866) 895-1099
    • Verizon - (800) 922-0204
    • T-Mobile - (844) 730-5912
  4. While this is the most inconvenient way to activate your phone, it is also the most sure-fire way to activate without any problems. [4] If you aren't able to activate online or over the phone, or didn't get a SIM card with your new phone, visiting the store will get your problem quickly solved.

  1. [5] Your new iPhone will come with a SIM card if your carrier requires one. The SIM card may already be inserted in your phone. Not all carriers use SIM cards.
    • The SIM tray can be found on the right side of the iPhone. Use the SIM removal tool or a small paperclip to eject the tray.
  2. New phones will take a few moments to boot up.
    • If you are trying to activate a used iPhone, you may be prompted to log in with the previous owner's Apple ID. The only way to bypass this is to perform a complete wipe and reset of the iPhone. If this still doesn't work, the previous owner reported the iPhone as stolen, and it cannot be activated.
  4. Enter in the password if the network is secured.
    • If you don't have access to a wireless network, you can plug your iPhone into your computer and use iTunes or Finder to activate the device. You will be prompted to activate automatically after plugging the phone in.
  5. [6] Your iPhone will attempt to activate automatically as soon as it connects to the wireless network.
    • If you receive a SIM card error, ensure that you have the correct SIM card inserted in the iPhone.
  6. After activating, the setup assistant will continue guiding you through the iPhone's setup process. [7]

Activating a Used Cell Phone

  1. In order to activate your used phone, you will need to insert a SIM card for your plan.
    • Unless the device has been unlocked, it can generally only be activated on the same carrier it was originally activated on.
  2. This may not be required during activation, but it can be helpful to have around.
    • Dial *#06# to display your new phone's IMEI number. You can also usually find it printed on the phone itself, either on the back or behind the removable battery.
  3. [8] The quickest way to get your used phone activated will be to call the carrier directly. It may be difficult to activate the phone using the online site, especially if it is older.
    • AT&T - (866) 895-1099
    • Verizon - (800) 922-0204
    • T-Mobile - (844) 730-5912
  4. [9] This is another way to easily activate your used phone. Make sure to bring in your SIM card, or let the employee know that you need to purchase a new SIM card.
    • It might be a good idea to listen to and write down any important voicemails on the old device before you activate a new one since there's a chance that your voicemail inbox may not transfer to your new device.
    • You'll also want to back up your old text messages, contacts, and any other data on your old phone. Like voicemails, there's a chance that your old text history, contacts, or other data will not transfer.

      Tips

      • Cell phones are programmed specifically to work with certain networks unless they are advertised as unlocked. If you wish to activate a pre-owned phone from one provider to another, such as activating a T-Mobile phone on Verizon, you might need to have the original provider unlock the phone.
        Thanks

      • Some cell phone providers use a communication process called global system for mobile communications (GSM) which requires a SIM card. Other providers use a process called code division multiple access (CDMA) which uses a card called a Removable User Identity Module (R-UIM) . A GSM phone will not work on a CDMA network or vice versa. If you are activating a phone that is not specified for your specific provider, call your provider to ensure that you can activate the phone on their system.
        Thanks

      • If your phone requires a SIM card, it should come with the phone. If not, you will need to purchase one specific to your intended provider. Removable User Identity Module (R-UIM) come with the phones and are not accessible on most CDMA phones without taking the phone apart.
        Thanks
