How to Unlock Samsung Galaxy S9

Why Unlock Your Samsung Galaxy S9?

When you buy a smartphone from any particular carrier in the United States, you are unable to use it on different carrier services. If you buy your phone from AT&T, you can never use it on different other networks such as T-Mobile, Sprint, etc until you unlock your phone. Carrier networks usually lock their SIMs so that their customers don’t leave them for their competition. It’s not permanent by any means as you can unlock them but they do it to discourage users from switching by adding some extra effort and time.

Not everyone may need their phone unlocked but there are times when you want to switch carriers for different purposes. You might want to switch your network services either because you are dissatisfied with your current one, other networks offer better or more affordable plans or you might be someone who travels a lot. You can unlock a carrier phone either by using a 3rd party website where you pay for your code or by getting it from your current carrier. When it comes to getting it from your carrier you might get it for free or you might have to pay depending on the network you have. Most don’t offer unlocks for free especially if the phone is brand new in the market.

The process of unlocking your Samsung galaxy S9 might be different for some carrier services and similar amongst others. Here are some of the ways in which you can unlock your Galaxy S9 device from some of the biggest carrier networks in the USA.

How to Unlock Samsung Galaxy S9 1

Unlocking Samsung Galaxy S9 on Sprint

Unlocking your Samsung Galaxy S9 on Sprint is similar to a few popular carrier services but there are a few key differences. For Sprint, you will either require an international unlock code or a domestic (United States) code. The former one will be needed if you need to take your smartphone to other countries whereas the latter will allow you to use it within the United States. However, there are also certain requirements you need to meet to get these codes. Some of the factors that play an important role in the approval process are the standing of your account, zero balance, non-usage of your device for illegal or criminal activities and whether your phone has ever been reported for being stolen. You also need to have used the device for a minimum of 50 days on their network. If you haven’t meet the above requirements, you won’t be eligible for getting the unlock codes.

Once all that is done, you can be on your way to unlocking your Sprint Galaxy S9 by following the steps given below.

Step 1 – Dial #06# from the device and get your IMEI number

Step 2 – Then call the Sprint customer service (1-866-866-7509)
