Why unlock Samsung A3 with Mobile Unlocked?

Mobile Unlocked uses your Samsung A3 IMEI number to scan Samsung databases to retrieve your Samsung A3 unlock code, which is the safest method of unlocking your Galaxy A3. As carriers and phone manufacturers use this method themselves, you can feel confident in knowing that our service is safe and legal and will not void your warranty.

Even if you are still under contract with your carrier provider, you can still unlock your Samsung A3 with us so that it is carrier free. This is great for taking your phone abroad, allowing you to switch to a local SIM instantly and save on unwanted roaming charges. Unlocking your Samsung A3 will also add value to your phone if you decide to sell it.

If you’re looking for a quick solution to unlock your Samsung A3, Mobile Unlocked provide a fast and efficient unlocking service. As soon as we receive your details and payment, we aim to get your Samsung A3 unlock code within 24 hours. This is then sent to you with easy to follow instructions to unlock your Samsung A3 remotely. There is no need to download software or apps as our Samsung A3 unlocking service is all done through Wi-Fi or your 3G/4G connection.

Samsung A3 Unlock FAQ

  • Why is my Samsung A3 locked?

    Usually when you take out a phone contract for a new phone the carrier provider will lock the Samsung A3 so that you can only use this on their carrier. The reason for this is to offer phones at a discount in exchange to pay for the contract. However, when your contract is finished your Samsung A3 is still locked down to the carrier, meaning you can only use a SIM card with the same carrier provider.

  • How do I know which carrier my Samsung A3 is locked to?

    It is important to know which carrier your Samsung A3 is locked to. If you are unsure, please use our carrier check tool to instantly find this out to avoid giving us wrong information.

  • Will my Samsung A3 be unlocked permanently?

    Yes. Once you have unlocked your Samsung A3 with Mobile Unlocked your phone will be unlocked permanently, even through future software updates.

  • Can unlocking my phone damage it?

    No. Unlocking your Samsung A3 with Mobile Unlocked will not damage it. Your Samsung A3 will still be in warranty as we unlock your Samsung A3 phone via IMEI, a safe and legal service to unlock your Samsung A3 with the unlock code, which is recommended by the carrier providers themselves.

Thank you MobileUnlocked! This was a much cheaper alternative to buying a new iPhone Pro Max! It couldn’t have been easier to unlock with MobileUnlocked, all I had to do was provide my imei number (it’s so simple and they clearly show you how to do this) and that was that. Amazing service – 100% would recommend!

Super Quick!

It was such a simple and cost effective process! My iPhone Xs was unlocked within no time and I will be returning to unlock my new Apple Watch 4.

I thought it would be complicated!

I can’t believe how quickly MobileUnlocked handled my request. Looking online, I read it can take up to 60 days to unlock a device, but MobileUnlocked unlocked my iPhone 14 Pro Max in under 24 hours! Fantastic service which I would highly recommend.

iPhone 11 Pro is Unlocked

This was such a quick and simple process, all I had to do was provide my imei number (which they tell you how to do) and I had my unlocked iPhone within 24 hours. Thank you MobileUnlocked!

Really Easy Process

So quick and simple! I followed the simple instructions MobileUnlocked provided and within 12 hours of placing my order my phone was unlocked. I would recommend this service to everyone and I will certainly be coming back when I need to unlock my next new phone.

Such amazing company!

MobileUnlocked are such a fantastic company! They don’t overcomplicate or overcharge, and their staff were both friendly and informative. My phone was successfully unlocked within hours, saving me both time and money. Highly recommend.

I can’t fault my experience with MobileUnlocked. I followed the clear and simple instructions on their website and my request was carried out the following morning. The service couldn’t have been easier, and the instructions couldn’t have been clearer. My phone is now unlocked and I can’t recommend this company enough.

Unlocked iPhone 6

Despite my phone being an older model, MobileUnlocked were still able to unlock it. The instructions were clear and simple, and my iPhone 6 was unlocked in no time (making me a huge saving!). Thank you MobileUnlocked! Highly recommend.
