It wasn’t that long ago that unlocking your cell phone was like going to the underground black market and purchasing some illegal unlock code, followed then by hitting up a dealer on the way home who dealt unlocking services as a side job. Nowadays, though, that’s all behind us. Thanks to the FCC, carriers must now allow you to unlock your phone if you meet certain requirements.
Here’s a quick look at the legal way for unlocking an AT&T cell phone.
Make sure you meet the requirements
First and foremost, you’ll need to meet the following requirements to unlock AT&T phone:
- Your contract has ended and all terms have been fulfilled
- If your contract hasn’t ended, your remaining balance and an Early Termination Fee will have to be paid
- Your account is in good standing
- The phone has not been reported lost or stolen
- The phone must be fully paid for
- Prepaid phones must have previously had active service with AT&T for at least 60 days
- GoPhones must have previously had active service with AT&T for 6 months
Locate Your IMEI Number
Once you have made sure that you meet the above mentioned requirements, you’ll then need to identify your phone’s IMEI number, which can be viewed by typing *#06# on your keypad and hitting SEND or CALL. You’ll receive a message with your IMEI number or it will automatically appear on your screen depending on the type of AT&T phone you have.
Give the Number to Your Unlock Code Service Provider
Contact the service provider who you are getting an unlock code through and give them your IMEI number. They will in turn give you an unlock code either for free or for a fee. Do keep in mind that you need to get the code from a trustworthy source or the data on your phone could be exploited. The service provider who gives you an unlock code should provide you with step-by-step instructions for unlocking your phone. If you have any questions, make sure to contact UnlockBase today.
When it comes to unlocking cell phones, you need to know whether or not it is CDMA or GSM. Most carriers in the United States — U.S. Cellular, Sprint and Verizon — use CDMA technology. T-Mobile and AT&T on the other hand use GSM technology. To keep things simple, if you want to unlock your phone, you must first identify what carrier the phone was originally used with. If it was with AT&T or T-Mobile, then you’ll need to go about the unlocking process keeping in mind that the phone operates off of GMS technology.
Here’s a quick look at the best and easiest phones to unlock over a GSM network.
Samsung Galaxy S5
Keep in mind that if you want to unlock your GSM phone, it will have to be used with a different carrier who also uses GSM technology. To unlock a Samsung S5, first remove the current SIM card and insert one from the carrier you want to switch to. Now, turn the phone back on. The phone will ask for an unlock code (SIM Network Unlock PIN). Enter the code that you purchased from a service provider. If it then asks for a Network Code, enter it as well. The phone should now be unlocked.
Samsung Galaxy Note 4
The Galaxy Note 4 is the flagship for Samsung when it comes to screen size and resolution. Fortunately, you can easily unlock your Samsung Galaxy Note 4 in as little as three steps. First, give the IMEI number of your phone to a service provider who sells unlock codes. To get this number, go to SETTINGS >> About device >> Status. Then, follow the directions given to you by the service provider and type in the unlock code when asked for it. That’s it; your phone should be unlocked.
HTC One M8
Need to unlock HTC One M8? This is another GSM phone that is incredibly easy to unlock. Simply remove the nanoSIM and replace it with one from the carrier you want to switch to. After turning the phone back on, enter the unlock code you received from an unlock service provider, and voila! Your phone is unlocked and can be used on any GSM network.

Huawei has a slew of top-of-the-line phones. Take for instance the P7. This finely-crafted phone might not be as powerful and bold as the Samsung S5, but when compared to other phones in its same class and price range, it definitely tops the list. At only 6.5mm thick and weighing only 4.37 ounces, this phone easily fits into your pocket. And don’t forget about the amazing camera and display screen.
As grand as the Huawei P7 is, or any other Huawei phone, service on the phones will of course be largely influenced by your carrier. If you have found yourself stuck in a contract that serves the purpose of nothing less than a burden, then take comfort in knowing that you can unlock your Huawei phone and switch carriers.
Tips for Unlocking Your Huawei Phone
The exact way to go about unlocking your Huawei phone will depend on the model that you have. No matter the model, though, you will need an unlock code. When acquiring this code, make sure it comes from a trustworthy source, or you might end up “bricking” your phone, meaning it will be permanently locked to your current carrier.
Also, make sure that you have step-by-step instructions for unlocking your phone according to the model that it is. If you go about unlocking the phone the wrong way, this can lead to a loss of data and files as well as “bricking.” On most models, you will have only three attempts to enter the unlock code.
To get an unlock code, you will need to give the source through which you’re acquiring the code and the IMEI number off of your phone. This number is usually found under the battery in the phone. On many Huawei phones, you will need two to four codes altogether (all of which come together when you get an unlock code): Network code, Service provider code, subset Unlock PIN, and/or Counter Unlock code. If at any time throughout the unlocking process your phone displays “simlock block unlock reset key,” then you will enter the Counter Unlock code.
Once you have completed the necessary steps involved in unlocking your Huawei phone, you can then use the phone on any compatible network carrier. If you have further questions about unlocking your phone, don’t hesitate to contact UnlockBase today.

Unlocking the boot loader on your Sony Xperia Z3 enables you to perform a variety of custom functions, from flashing custom kernels and ROMS to initiating rooting features. Before you implement the methods detailed below, remember that Sony’s warranty doesn’t cover mishaps resulting from custom tweaking, such as bricking. Back up the contents of your phone, as all data will be erased upon unlocking.
Preparing to Unlock the Sony Xperia Z3
- Verify that you have installed the Android ADB and Fastboot drivers on your computer using the Minimal tool’s quick setup feature.
- Check whether your phone supports unlocking of the boot loader. Navigate to the dial pad on your phone and type *#*#7378423#*#*.
- Once the code is entered, a menu appears.
- Navigate to Service info > Configuration > boot loader Unlock. If the message reads “Yes,” you have confirmed that the phone supports unlocking of the boot loader. Otherwise, you can check whether the boot loader is already unlocked, which may be the case if your phone was pre-owned.
- Navigate to the dial pad and type *#06#* to display your phone’s IMEI number. Record the number for reference.
- Turn off your phone.
- Launch the Minimal ADB and Fastboot command prompt.
- Press and hold down the Volume Up button on your phone and connect the USB cable from your phone to your computer. If you have a modified Z3 phone, try pressing and holding down the Back button instead.
- Verify that your phone is using the most recent Android firmware. Unlocking the phone with older firmware installed may cause the camera to stop working.
- Type fastboot.exe -i 0x0fce getvar version into the command prompt and press Enter. The window will output a response value in the form of a decimal. If this value is displayed, then the phone is properly set up.
- Navigate to the Sony Developer unlock web page and read and accept the terms and conditions to proceed. Note that your warranty may be void if you proceed.
- Type your name, your Xperia Z3’s IMEI number barring the last digit, and your email address into the appropriate fields. Click the Submit button to send an unlock code request to Sony.
- Check your inbox for an email from Sony containing your Xperia Z3’s boot loader unlock code. If you don’t see the email after waiting a few minutes, check your Spam folder.
- Type fastboot.exe -i 0x0fce oem unlock 0xCODE into the command prompt, replacing code with the unlock code you received from Sony. Press Enter to fully unlock the boot loader. The command prompt should display logs.
- If the above steps didn’t work, consult a professional phone unlocking company for more advanced services.
Relocking the Sony Xperia Z3
After you unlock the Xperia Z3, relocking it is easy, even for people without experience. Relocking the boot loader enables the phone to access important system updates and lets you fix system issues via SEUS/PCC. Follow these steps to relock your phone:
- Verify that FlashTool is downloaded and properly installed on the phone.
- Download the appropriate FTF Z3 boot loader relock file to your computer.
- Open the FTF file in FlashTool. When the flashmode prompt appears, turn off the phone and, while holding down the decrease volume button, connect the USB cable from your computer to your phone to enable flashmode.
- Restart your phone after the flashing completes to fully relock the Z3 boot loader.
- As with the unlock procedure, if you have trouble relocking your phone, search online for a reputable phone unlocking company for tailored services.

Imagine this scenario: you recently obtained your very own HTC One and you immediately fell in love with it. Unfortunately, soon after, you found out you need to switch cell phone providers for a better rate or higher data allowances. In this situation, you might be tempted to scrap it all and find a different phone that closely meets your needs. Fortunately, you can actually unlock your HTC One and use it with an alternate provider in just a few easy steps. Here are three different ways to make this happen.
1. Fight With Your Provider
Although it is not widely advertised, your current cell phone provider has the ability to instantly unlock your phone. You can give the tech support line a call to start the unlock process. Be sure to have your International Mobile Station Equipment, or IMEI, number on hand before calling, as you cannot retrieve it while on a call.
To find this number, you need to locate the about page on your settings menu to locate the phone identity. You will need to prove your identity and ownership of the phone while talking with the technician. After that, the tech will walk you through the unlock process from start to finish.
2. Fill Out an Online Request Form… and Wait
If your cell phone company’s technicians are not forthcoming with information about unlocking your phone, head to their official website to complete the process on your own. You can fill out an unlock request form on the site or begin the process using the provided drop boxes. The downside? This will usually take quite a while; you may not get a response for a few days.
3. Try to “Hack” Your Way In
Want a cheap solution? You might be tempted to try to “hack” your way into your phone. This is often done by contacting a “hacker” on the web or by downloading free software that claims to be able to unlock your device. Unfortunately, this often leaves you with a “bricked” (unusable) phone. It can even damage your computer system, as the “free” software could be filled with viruses and malware.
4. Go to a Service Center
There are usually local service centers available that advertise that they will unlock devices. Usually you will drop your phone off and they will call you back in a few days when it’s unlocked. The downside to this type of service is that it tends to be fairly expensive; you’ll usually be paying two or three times what you would pay through UnlockBase.
5. Get a Code through UnlockBase
If you don’t want to mess with sleazy hackers, expensive service centers or stubborn network providers, you can simply get an unlock code through UnlockBase. The process takes less than 30 minutes; all you need is the IMEI of your cell phone and you’re in business! UnlockBase is less expensive and faster than other options, and it doesn’t carry with it the risks of trying to go through a hacker or unlock your phone on your own.
Finishing Up After the Unlock
No matter which option you choose, you will likely need to wait an hour or two for your phone to fully transfer over to an open configuration. Once you use the unlock code and install the files, you can discard both of those items as your phone will be ready to receive the new cell phone provider information without any further changes.
You may be prompted to update your phone again if any of the integral systems are deemed outdated upon signing up with the new provider. These subsequent updates can usually be performed over the cell or Wi-Fi network. If you are unhappy with the chosen provider, you can switch again by following one of the above options in exactly the same manner.

Since 2008 the Sony Xperia (a name taken from the word experience) line of smart phones and tablets have been a mainstay of their mobile device line. Growing with the new world of hand held, mobile computing, Xperia products first began incorporating the Android operating system in 2010. Every new piece of technology released in the Sony Xperia line is a chance for users and techies alike to explore the possibilities offered by the continued improvement in functionality and processing capabilities. The announcement about the newest addition to their smart phone line, the Xperia Z3, already has tech sites buzzing about the device while carefully examining its capabilities.
Bootloaders, Smart Phones and You
The world of DOS, Windows and now Android has always been about allowing users the freedom to customize their experience. Open source code and the world of innovation allowed continuous improvements and changing. Savvy smart phone users figured out that by unlocking a phone’s bootloader many major pieces of software could be modified and customized. A bootloader is the instructions guiding a phone during start up. Unlocking the bootloader allows for new operating systems to be installed and loaded that have been developed specifically for Android based phones such as Ubuntu or Cyanogen. However, there are potential drawbacks if you decide to modify your smart phone.
Sony Warns Xperia Users Against Unlocking Bootloaders
Smart phone manufacturers are generally against users unlocking the bootloader on their device. Obviously there are monetary reasons for this, as manufacturers contract with software companies to create the platform and related applications on any given device. Furthermore companies warn that the integrity of security may be compromised by altering the configuration of a device. Sony states on their website that unlocking the bootloader on their Xperia Z3 device will void the warranty due to these concerns. Sony additionally warns users that unlocking the bootloader may cause certain preloaded applications to fail, prevent updates to software and cause users to be unable to purchase and download anything from Sony’s digital storefronts.
DRM Keys and Mobile Devices
The reason that unlocking the bootloader on the Sony Xperia Z3 may cause so many problems for users is the face that in doing so the device’s DRM keys will be deleted. DRM (digital rights management) security keys allow a smart phone to prove that it has the right to use certain applications or online purchases related to the device. When these keys are lost by unlocking the Xperia’s bootloader certain applications become unusable and users are unable to prove to Sony’s online storefronts that the device is compatible and secure. The decision by Sony to make these DRM keys linked to the system’s bootloader leaves users with a difficult decision to make if they want greater customization options.
Sony Xperia Camera Algorithms Affected
The loss of the Xperia’s DRM security keys also reportedly affects the functionality of the device’s camera. The camera on the Xperia Z3 has been billed as one of the smart phone’s major strengths, producing crisp, clear images. The loss of the DRM keys due to unlocking the device’s bootloader apparently affects the camera’s image quality. This is due to the fact that the camera’s advanced algorithms controlling image quality are controlled by the DRM keys. While this type of result occurred in the past with other Sony devices, several sources that got their hands on the Xperia Z3 early have released images showing a significant reduction in quality.
Hopefully you can unlock your Sony without compromising the Bootloader. To avoid any issues, we recommend ordering the factory unlock code of your Sony Xperia Z3. Ultimately it is the user’s decision to modify their device or make major changes through unlocking the bootloader. It is important to understand the positives and potential drawbacks before making a decision that could potentially affect your smart phone’s performance, software and warranty. If you are thinking about purchasing the Sony Xperia Z3 be sure to look into all the possible consequences before making a decision about modifying your device.
