If you want to use your iPhone with another provider, all you need to do is contact the original mobile service provider to request an unlock, which usually takes only a few days. Unfortunately, you must meet certain criteria to officially unlock your iPhone, such as: For example, full payment for the device and completion of contracts. This does not mean, however, that there is no workaround that you can use before.
An exploit has been found in iOS that allows you to unlock your iPhone for use with any GSM network; This is done using an external SIM chip, which allows you to change the ICCID that the iPhone holds connected to the SIM card to effectively spoof the device. The process is fairly simple, although there are a few factors to watch out for as you go through the process.
Read on to learn how to unlock a network-secured iPhone purchased from a third party as is or with an installment plan from your carrier. Luckily, it's pretty simple and does not even require jailbreaking. Note that this guide assumes you are using the latest version of iOS.
Before we get the ball rolling, it's important that this process requires an R-SIM 1
This network unlocking method works on the following GSM and CDMA-based iPhones on iOS 11 through iOS 11.4.1:  iPhone 5
Please note That this unlock is not permanent and can easily be undone if you update your iPhone to the latest iOS firmware or reboot hard. You can unlock your device again using the same steps. Remember, before you continue. Finally, the provided ICCID code will be changed, so we will update it constantly as soon as a new code appears.
If the code we provide does not work for you, Twitter will scroll at any time to search for ICCID codes that might work for you.
Step 1: Turn Off My iPhone
Before you proceed with the actual unlock process, we recommend that you disable "Find My iPhone" during the procedure. Go to Settings, tap your name, choose iCloud, then scroll down and tap Find My iPhone. Uncheck the "Find my iPhone" button.
You will be asked to enter your Apple ID password. So enter your credentials to turn this feature off.
Now you can start the unlock process. Therefore, remove the iPhone's SIM tray using an eject tool or a paper clip from the device. If a SIM card is already inserted, remove it.
Insert the R-SIM card into the SIM tray. Pay particular attention to the orientation of the R-SIM card to avoid damaging the chip. Be sure to slide the tab under the compartment so it does not get stuck in your iPhone.
Once the R-SIM chip is secure is attached, place the unsupported Nano SIM card on top of it. For example, if you have an iPhone with Sprint lock, throw a T-Mobile SIM card there.
Make sure everything is flush with the SIM tray. The contacts that are connected to the SIM card are extremely thin metal strips that can easily break off. So be careful. Once you are satisfied, insert the SIM tray into your iPhone.
Step 4: Edit the ICCID of the SIM Card  If the R-SIM Card and the new SIM card connected to your iPhone, open the "Phone" app, and then tap the "Keypad" tab to open the Phone Dialer. When you are taken to the activation screen, either long press the side button (iPhone X) or three times briefly press the home button (iPhone 8 and below) and then select "Emergency Call" to get to the dialer app Choose there one of the numbers and then click on the green call button.
* 5005 * 7672 * 99 #
* 5005 * 7672 * 0 #
* 5005 * 7672 * 99 # * 5005 * 7672 * 0 #
When you call, you will be immediately forwarded to the R-SIM information page, so scroll down to the bottom of the screen and tap "Edit ICCID" in the menu bar. You will be prompted to enter the 20-digit ICCID code. Enter the following numbers:
After entering the ICCID code, click Submit See a toast page to confirm successful setup. Although the page states that you should restart your iPhone now, do not do it yet; Instead, tap Accept in the lower right corner. Once you're done, turn off your iPhone as usual.
Step 5: Turn On and Activate
Turn the device back on and on Continue the activation / setup process as usual. Once activation is complete, you should be able to use your iPhone with your new SIM card to make calls and communicate via messages. You can also use web-based services like YouTube, Safari and more.
At this point, you can remove the R-SIM card from your iPhone and use only your SIM card. However, we recommend keeping the R-SIM card as it will not affect your device in daily use. In addition, leaving the chip in your iPhone protects against loss and damage. This is extremely important as the iPhone is unlocked.
Step 6: Retry (if necessary)
As mentioned above, this carrier unlock method uses an exploit to manually accept the ICCID of your iPhone from a SIM card that is not supported by an otherwise supported network. However, this trick can easily be undone if you either upgrade to the latest version of iOS or restart your device. If you did the latter, you will need to follow the steps above to unlock your iPhone.
For this reason, we recommend that you refrain from iOS software updates to get your activation, especially through iTunes. Some reports claim that the over-the-air (OTA) update preserves the hacked ICCID and unlocks it, but we have not been able to confirm it with absolute certainty. We will definitely keep you up to date as there are more concrete information spaces and new ICCID codes that are displayed regularly.
