Samsung phones are immensely popular around the world for their slick designs, powerful performance, and jam-packed list of features. However, most Samsung devices sold by carriers come locked to that carrier’s network. Thankfully, there are a variety of Samsung unlock codes you can use in 2024 to unlock your Samsung phone and enjoy complete freedom over network selection.
Why Unlock Your Samsung Phone?
Here are some key benefits of unlocking your Samsung device:
- Use any GSM SIM card worldwide on an unlocked phone. No restrictions to specific carriers.
- Enhanced resale value for an unlocked Samsung phone on sites like eBay or Craigslist.

Essentially, unlocking frees your Samsung device from carrier limitations connected to both hardware and software. Even if you don’t plan on switching networks, there are still compelling reasons to get your phone unlocked for full customization.
How To Check Lock Status on Samsung Phones
Before diving into specific Samsung unlock codes, you should first check if your Samsung phone is actually locked or not. Here are two easy ways to verify the lock status:
- Insert Non-Carrier SIM Card: Power off your phone, remove the active SIM card, insert another carrier’s SIM card, turn on your phone and observe any error prompts related to SIM network lock.

- Try calling your wireless carrier first to politely request an official unlock before attempting DIY unlocking methods. Some will provide this instantly while others make you wait out the contract.
- If your Samsung phone displays error prompts like “SIM Network Unlock PIN Required” or “Unable to Process SIM Card”, then it indicates your carrier applied extra encryption measures preventing casual unlocking with the usual codes, requiring professional services instead.
- Very old legacy Samsung phones may not unlock properly nowadays due to outdated software or disabled unlock servers on the carrier backend. Your only options are using the stock SIM forever or getting a replacement device.
- If Samsung codes fail to unlock the device, you can still look into paid services from third-party unlocking websites offering online solutions through cable connections. However, use such services as a last resort because quality vastly varies.
- Once successfully unlocked using the provided instructions, your Samsung phone should display status updates like “Network lock – Disabled” or “Phone Unlocked” within the Settings app. If unsure, inserting other carrier SIM cards is another quick way to double check if the unlock worked.
- After the unlock, you may need to manually flash regional firmware again depending on where you want to use local SIM cards when globally traveling. This step isn’t necessary if sticking to the original carrier network region.
In summary – first try codes from this guide, call carrier next for help, finally use professional unlock services before replacing the Samsung phone entirely. With some guided effort, you can definitely unlock your specific Galaxy model 100% free without extra costs if the device is eligible.
