What Are Phone Unlocking Services

Phone Unlocking Services offer a convenient and reliable path to unlocking your SIM-locked phones from any carrier in the world remotely. The top providers have relationships with hundreds of cellular phone carriers around the world and can safely and permanently unlock individual or bulk-quantities (100s to 10,000s) of iPhones, Samsung, other smart phones and even legacy flip phones with just their IMEI number. 

Why Use A Phone Unlocking Provider

Why should you use a Phone Unlocking provider? Excellent question! If you have you have one or more phones that need to be unlocked, they’re on different carriers and you have no time to be calling either carrier to unlock them — using a third-party unlocking provider is the #1 way to go. Authentic, legal and convenient unlocking for busy owners. Spend less than 5 minutes ordering the unlocks and save countless hours unlocking them yourself. 

Unlocking services are also very useful for complex situations where you have locked phones from multiple mobile carriers, countries and owners. It makes unlocking as simple as ordering on Amazon. 

Are Unlocking services safe?

Are unlocking services safe? The answer is yes — authentic Phone Unlocking services are 100% safe, legal and will actually save you time and energy unlocking phones. They have partnerships and authority to unlock your phone and do so remotely and permanently with just your IMEI.

Unfortunately, like any industry, there are plenty of bad rotten eggs out there. Among all of the authentic unlocking providers, there are scammers and cheats who promise everything and deliver nothing, or worse — steal your info. These are the guys we help you avoid with our reviews and recommendations. 


How It Works?

Here’s how phone unlocking services actually work:

  1. Choose a Unlocking Provider and place an order to unlock your phone. To do this, you’ll need to find and enter your phone’s IMEI number. Dial *#06# on your phone to pull it up. 
  2. The Phone Unlocking provider you choose will check your IMEI to ensure its able to unlock your phone (ie. It’s not blacklisted, stolen or under contract).
  3. Once cleared, the unlocking provider sends a special request to the carriers or phone maker the phone was locked by
  4. The request is made to remove the locked flag for the IMEI and carriers notifies the phone manufacturer to remove the restrictions.
  5. The restrictions are either removed remotely (such as iPhones) or via Unlock Code which the maker would send your Provider, who then provide you with it.
  6. When the restrictions are removed, you can can  activate your phone with any other carrier’s SIM card. Viola! Boom! DONE. That’s all she wrote.


Most of this happens automatically via software and API connections, so your personal information is never accessed or revealed to third-parties. Some unlocks need to be performed manually or require additional steps or methods. Since mobile carriers provide the authorization to unlock or whitelist phones to these third party providers, is an authentic and convenient method to unlock your phone(s) permanently. 

The average cost of unlocking a mobile device

The average cost of  unlocking a phone varies based on the phone model, carrier it’s locked to and quantity of phones. Prices range from a 10 cents, all the way to $300 for some rare cases. On average, consumers pay $15-30 to permanently unlock their phones, while wholesalers & resellers (100 to 10,000 unlocks monthly) can expect to pay around $1 to $20 per phone. 

  • Unlocking Services for Older Smart Phones & Androids are generally cheaper, ranging around $5 to $20 per phone.
  • Unlocking iPhones are generally more expensive, with prices ranging from $15 to $130 per iPhone
  • Unlocking Factory Locked Phones that require an Unlock Code usually cost around $10-20, but can range from less than $1 to as high as $50 based on the phone make and country.

Frequently Asked Questions

If you’re searching what is IMEI, we have the answer you’re looking for. IMEI stands for International Mobile Equipment Identity and is a unique number for identifying a device on a mobile network. Think of it as your phone’s VIN number or Tax ID. Every IMEI is 15 digits long, and is assigned to every mobile phone, including CDMA phones, which call it a MEID number.

An IMEI number can be used to identify and discriminate against a phone if it’s lost or stolen. It can be used to assign virtual SIM cards, and be blacklisted or whitelisted by a mobile carrier. IMEI information is available online so with just those 15 numbers, you can check whether a phone has been reported lost, is blacklisted, was subject to an insurance claim, or is totally clean. 


The IMEI number also reveals loads of other details about a phone. These include the brand and model, year of release, and specifications. You can try this out by visiting and typing in your phone’s IMEI number — it’s free.

A PUK code stands for “Personal Unlock Key.” It’s a unique code that is linked to your mobile phone’s SIM card and is usually 8 digits long. You will need the PUK code if you have set a SIM Card lock and entered the wrong passcode 3 times. Your phone will become locked, and you will need the PUK code to unlock it.

A PUK code is the unlock code you need to unlock your phone. 

Insert a SIM Card from a different carrier than the one your handset is using. When power up is complete the handset will display a message like those below if it SIM locked :

– Enter Subsidy Code
– Enter Unlock Code
– Incorrect Sim Card
– Insert Correct Sim Card
– Invalid Smart Chip
– Phone Restricted
– Sim Network Unlock Code
– Sim Network Unlock Pin
– Special Code Required
– Wrong Sim Card
– Network Lock Control Key
– Sim Password
– Incompatible Sim
– Enter Subsidy Pin

Sometimes. It depends. You can unlock your phone for free by calling your carrier and checking if you qualify. You’ll usually have to wait on hold for awhile and can only do so if you meet certain requirements such as being the original owner, the phone is paid off and you don’t have a contract or commitment with the carrier.

It’s 100% legal to unlock your phone in the United States, so even if your carrier doesn’t want to unlock your phone or if you have multiple phones from various carriers — you can still unlock your phone by using a third-party unlocking service. These aren’t free but will save you time and hassle by doing all of the leg work for you.

If you are unlocking phones, checking IMEI numbers is routine. However, doing it efficiently is key. 

To check IMEI numbers in bulk manually, use a IMEI checking dashboard with Bulk options, that allow you to just copy, paste and check thousands of IMEI at once. 

However, the best option is still automating. You API that bad boy and automate the hell out of it.
