The Key Difference Between Locked and Unlocked Phone

When it comes to purchasing a smartphone, you have two options. You can either buy a locked phone, or you can buy an unlocked phone. It’s best to know the difference between these two terms so that you’re able to make an informed buying decision.

Unlocked phone – is a phone that company sells directly or indirectly. For instance, if you buy the phone from a company retail outlet or an official reseller of the handsets. It’s also referred to as a factory unlocked phone. The benefit of purchasing an unlocked phone is that you can use it on any carrier across the globe. Plus, it has a higher resale value.

Locked phone – is a handset that’s sold by a carrier like Verizon or AT&T. And it’s locked to the specific carrier’s network. Hence, you can’t use it on any carrier other than the one it’s locked to. You won’t be able to make calls if you attempt to. This means you need to use the same carrier when traveling, which could result in expensive roaming charges.

Typically, locked devices have a contract term of 1-2 years. And upon maturity, the carrier might be willing to unlock your phone. Once you’ve paid the entire contract amount or after the contract ends, you’ll need to call the carrier to unlock the device.

Below is how to check whether the device is locked or unlocked.

1. Check if Phone Is Unlocked or Not via SIM Card

The easiest way to check if your phone is locked or unlocked is by taking out the SIM inside and putting in a different carrier’s SIM card. You can get in touch with an independent seller and request him to allow you to insert a different SIM. When you do:

  • Call someone with the current SIM card first. This helps to ensure the device is functioning on the existing SIM.
  • Switch your phone off, remove the SIM tray, take out the SIM, and put another carriers’ SIM.
  • Switch on the device
  • Check whether the new SIM was accepted or rejected

You can then test the new SIM by seeing the carrier’s signal and making a call. Unlocked phone will allow the call to take place. Typically, if the phone is locked and you insert another carrier’s SIM, a pop-up message displays saying “unsupported sim.” In some cases, a SIM icon will appear on the signal bars with a slash or a cross sign in front of it.

2. Use the IMEI-Method to Check Locked or Unlocked Phone

The IMEI number can also help you determine whether the phone is locked or unlocked:

  1. You need to first find the IMEI number of the phone you’re about to buy. To check the IMEI, dial *#06# on the dialpad if the device is with you, or request it from the seller.
