How to SIM unlock the Samsung Galaxy Z Flip 4 for FREE


The Samsung Galaxy Z Flip 4 is one of Samsung’s best foldable smartphones that money can buy. While we can appreciate the novelty of having a phone that can unfold into a tablet, there’s a nostalgia factor involved with the Flip 4 that reminds us of the good old feature phone days when flip style phones were all the rage.

Plus the fact that when folded shut it becomes even smaller makes it the perfect device, especially in this day and age where smartphone displays are becoming too big and unwieldy.

That being said, the Flip 4 is a flagship phone and with its foldable display technology, it commands a premium which means that for some, buying it on contract with a carrier is the only way that they’ll be able to afford it. Unfortunately, buying it on contract does come with some downsides, one of which is that the SIM card will be locked to your carrier, which can be troublesome if you need to swap it out.

The good news is that if you need to unlock the SIM card for your Galaxy Z Flip 4, it’s actually a really easy process and we’ll be showing you how to get it done for free, or alternatively, use third-party services like Android SIM Unlock.

Unlock the Galaxy Z Flip 4 for free

Obviously the ideal method would be to unlock the SIM of the phone for free and this is possible through your carrier. But keep in mind that there might be certain requirements you’ll have to meet in order for this to work, and while it may vary from carrier to carrier, the general requirements are:

  • You need to be in good standing with your carrier, meaning that you don’t have any outstanding bills and that the contract with your carrier for the phone has expired
  • You’ll also need to make sure that you have owned the device for at least 60-90 days

Assuming you meet those requirements, then the process of unlocking the SIM is pretty easy, just follow the steps below:

  1. On your Samsung Galaxy Z Flip 4 handset, launch the Phone app and dial *#06# to pull up your phone’s IMEI number
  2. Write the IMEI number down somewhere so you can refer to it later
  3. Call your carrier and request for your SIM unlock code
  4. You will probably be asked to provide the IMEI for the Samsung Galaxy Z Flip 4’s
  5. If you meet all the requirements that we mentioned above, the SIM unlock code will be sent to the email address you provided in the next 2-5 days.
  6. Once you’ve received your code, swap out the SIM with a SIM from another carrier
  7. Enter the SIM unlock code that you received in your email when prompted and you’re set!

If your phone was only just released and is still relatively new, there is a good chance your carrier might reject your request to unlock the SIM of the phone. You can get around this by buying your way out of the contract, but that would be too expensive and defeats the purpose behind buying it on contract to begin with.

A good alternative would be to use services like Android SIM Unlock where for a small and very affordable fee, you’ll be able to unlock the Galaxy Z Flip 4’s SIM card quickly and easily, even if you’re still tied to a contract with your carrier, and here’s what you need to do.

  1. On your Samsung Galaxy Z Flip 4 phone, launch the Phone app and dial *#06# to get the device’s IMEI number
  2. Write the IMEI number down
  3. Go to Android SIM Unlock’s website
  4. Enter your device’s IMEI number
  5. Complete the checkout process with your payment and contact information
  6. Once payment is made, you should then receive the Samsung Galaxy Z Flip 4’s unlock code either through SMS or email
  7. The moment you’ve received your code, you can then swap out the SIM on your phone with a SIM from another carrier
  8. You should be prompted to enter the SIM unlock code that you received in your email, and once you’ve done that, you should be good to go

We would like to remind you that unlocking your phone’s SIM, whether it be through a carrier or using Android SIM Unlock, does not release you from any contractual obligations you might have. You’re still expected to pay your bills in a timely manner and if you’re still on contract, you’ll have to keep making those repayments until the end.

The only difference now is that you will have the freedom to swap your SIM cards around as and when you need, which is particularly helpful when traveling to foreign countries and you need to use a local SIM and if eSIM is unavailable.
