Tip 1: What does It Mean When A Phone is Carrier Locked?

Telecoms operators can make agreements with phone manufacturers to develop special software code that prevents the device from being used on any other network. These software locks can, however, be unlocked by using different software code to unlock the device.

The mobile devices usually locked in this manner are bought by the users on the contract during which they receive a discount, and the user is expected to abide by the contract terms which usually lasts for two years. For iPhone contracts, this agreement makes it easy for the mobile operator to recoup their investment after offering the user a discount for the device. If you wish to cancel the contract, you will be charged a termination fee which will cover the remaining payment value.

There are also some deals where iPhones are sold without discounts, but they are carrier locked. If you wish to buy an unlocked phone, you must directly ask for a phone that is unlocked to avoid making a costly mistake.

Tip 2: What is The Importance of Unlocking Phones?

Unlocked phones can be used with any carrier or network worldwide on the GSM band. Using the phone is as easy as choosing your preferred network and inserting the SIM card.
Unlocked phones give you the freedom to choose your preferred carrier. Always ask for proof to be sure that a phone is unlocked before purchase.


There is a vast market for pre-owned phones. They are sold at cheaper rates by owners who want to upgrade their devices. You can purchase these iPhones/iPads and enjoy using them but they must be unlocked, or you may encounter difficulties. Before payment, request for the IMEI. With the IMEI you can determine the status of the phone. If the seller is unwilling to reveal the device’s IMEI, you may want to buy from another seller to avoid issues after purchase.
