What You Need to Know About Sprint Carrier

Sprint was once one of the major wireless carriers (telecom companies) in the United States. It offered nationwide coverage and a range of mobile plans and devices. However, on 1st April 2020, T-Mobile officially acquired Sprint. The two networks merged to create a larger, more unified carrier. As a result, Sprint no longer operates as a separate brand. Now, all Sprint customers are under the T-Mobile umbrella.

How to Unlock Sprint iPhone in 2025

Unlocking a Sprint iPhone isn’t always easy, especially after the Sprint-T-Mobile merger and the use of older carrier systems. However, there are still effective methods available. No matter if you go with a carrier unlock, use a SIM chip, or try a third-party option, we’ve outlined the step-by-step process to unlock your Sprint iPhone.

Way 1. Unlock Sprint iPhone with T-Mobile Carrier

Requirements:

  • Your phone’s IMEI number: you can dial *#06# to find it.
  • Your T-Mobile account information. 
  • A proof of purchase or receipt, especially for used phones.

Success Rate:

Medium(50%). It’s because it requires the T-Mobile account access. If you don’t have it, you need to contact T-Mobile customer care. The perception of Sprint as a separate brand creates confusion and delays, making it tough to unlock older Sprint phones. This has left Sprint phone users without a direct way to request or complete an unlock.

Steps to Unlock Sprint iPhone via Carrier

Step 1. For iPhone, you must call T-Mobile Customer Care for SIM unlocking. You can reach them at 1-877-746-0909.  Just provide your IMEI number and explain the entire scenario.

Step 2. Wait for the approval. Once your unlock request is approved, T-Mobile will send unlock instructions. It can take 1 to 7 days commonly. 

Way 2. Unlock Sprint iPhone Without Account Using Passixer

Requirements:

  • Your Sprint iPhone

Way 3. Unlock Sprint iPhone Online Via IMEI

Requirements:

  • An active/stable network connection
  • The IMEI number of your phone
  • A reliable online iPhone unlocker service (e.g. Official SIM Unlock)
  • An active email address/ID

Success Rate:

Low(30%). Most online services rely on carrier partnerships or authorized channels to process unlock requests. However, there’s no guarantee of success. They might assure you the unlock code will arrive within 15 minutes to a day, but there’s no certainty it will, despite payment.

Way 4. SIM Unlock Sprint iPhone Without Computer with SIM Chip

A SIM chip (also known as a hardware unlock chip) is a thin adapter placed under your regular SIM card. It works by tricking your iPhone into accepting a SIM from a different carrier. It allows you to bypass the SIM lock without needing a computer or an official carrier unlock.

This method is beneficial to unlock Sprint iPhones where traditional unlocking isn’t available or supported. While it doesn’t require any computer or software, you must get the SIM chip beforehand from online marketplaces.

Requirements:

  • A Sprint iPhone
  • SIM unlock chip (e.g., R-SIM cards)
  • New SIM card from a different carrier
  • Correct ICCID code

Success Rate:

Low(30%). It’s because this method works temporarily and is short-lived. It operates on an unlock-never-upgrade policy and the effects are lost after an iOS update. As a result, with each iOS upgrade, you need to find a new ICCID number. In addition, the incorrect operation of the chip results in damage to the SIM card tray. It can lead to other problems with the network, software, and so on.

Steps to Unlock Sprint iPhone Using R-SIM

Step 1. Put the R-SIM chip along with the new SIM into the SIM tray of your iPhone.

Step 2. Slide the SIM tray into your iPhone. After a brief pause, you’ll see the setup screen and a pop-up asking about choose a supported carrier.

Step 4. Restart your iPhone. As soon as it reboots, the new network will appear temporarily.
