Can flashing a phone remove a network lock?
If your phone is locked, it will stay locked after you flash a new firmware, and if it's unlocked it will stay unlocked. However if you want to unlock a phone with unlock codes you must revert the firmware to stock if you change it with a custom ROM.
When a handset is locked it means it will only work with the provider that you bought it from. If your phone is locked it won't automatically become unlocked when your contract expires with your provider. You'll have to specifically ask your carrier to unlock it.
Performing a factory reset on a phone returns it to its out-of-box state. All your apps and data are wiped clean and you have to go through the setup process again. If a third party reset the phone, the codes that changed the phone from locked to unlocked are removed.
Rooting a phone will not carrier-unlock it, but it will let you customize the operating system or install a new one. Both types of unlock are legal, although a SIM unlock often requires help from the network/carrier.
If you've not forgotten yet, the most prominent way of flashing a locked Android phone is by hard reset—which doesn't require going through the phone's settings. Basically, all you'll need is to power off and boot the device into recovery mode to perform a hard reset.
But before jailbreaking, you may ask: Does jailbreak remove carrier lock? Or, can I jailbreak my iPhone to unlock carrier? Yes, absolutely. As we mentioned, you can get more freedom after you unlock iPhone with jailbreak, including unlocking carrier.
You have three options to unlock your smartphone: Contact your carrier. Buy an unlock code online. Make sure your new phone isn't locked in the first place.
What Is SIM Network Unlock PIN? SIM Network Unlock Pin (NUP) is a code used to unlock an Android phone or iPhone from its original carrier so that it may be used on other carriers. This code is typically 8 or 16 digits long and is used to unlock a smartphone.
The Network Unlock Code (NUC), sometimes called a Network Unlock PIN (NUP) or Network Control Key (NCK), allows you to unlock a mobile phone from its original network. If you've not received a NUC you can request one.
The reason many network providers SIM lock their phones is that they offer phones at a discount to customers in exchange for a contract to pay for the use of the network for a specified time period, usually between one and three years.
Can you get rid of a carrier lock?
You'll have to specifically ask your carrier to unlock it. This can be bypassed by modifying the phone (Rooting or Jailbreaking depending on if you're using an android or iOS device) and installing certain tweaks that match your situation.
If a cell phone is locked, it means that the phone can only be used on one specific carrier's network, like only on Verizon service, or only on AT&T. Carriers will install software on the phone to lock it to their network.

Device Unlock is an Android app that allows you to request and apply a mobile device unlock directly from the device.

Absolutely not. Rooting and Removing a carrier lock are two completely different processes. By rooting an Android phone you'll get superuser permissions, like getting access to androids internal folders and getting control over your entire filesystem.
The Sim Lock is not the same thing as Carrier Lock. Sim Lock,. simply means the actual SIM card is what is locked, not your iPhone. If your iPhone were locked and you insert a sim from a carrier that is different to the one it is locked to, it would say Sim not supported, not sim locked.
No, changing the IMEI number will not unblock the number as the only carrier is able to do that. If your number gets blocked after activation, you can reach the carrier where it is locked to. The original IMEI number is mandatory to unlock the phone as its hardware is encoded into the phone.
Can you sell a phone locked to a carrier?
If your iPhone is currently locked to a network, it is legal to sell it even if you still owe money on the phone contract. Most networks do not want the phone back if you can't pay your bill or decide to sell it. They simply want the money you owe them.
If you're buying a used phone, make sure it is unlocked first. Carriers will often only unlock phones associated with accounts in "good standing," which means the person selling you the phone needs to request the unlock before canceling their service or selling it to you.

First of all, you have to turn off your mobile phone and take out the SIM card. Then turn on the device without the SIM card and wait for it to show a message with the instruction to insert the SIM card. From that moment you will need to write the IMEI code to unlock the phone.
Enter the default PIN 1111 or 1234.

Restoring the phone to factory settings will not remove the carrier lock. You should contact your carrier to arrange for that before restoring the phone.

A third-party backlist removal service can assist you in your iPhone blacklist status. Generally, unlocking your iPhone device and completing the blacklist removal process allows you to select any other carrier for your phone.
A carrier-imposed “lock” is a software code that prevents your phone from working on another cellular network. With an “unlocked” phone, on the other hand, you can get service with any carrier on a compatible network — and that's just one of the benefits of an unlocked phone.
The main disadvantages are that you could brick your device, permanently. If it's still under warranty, it will also good the warranty, but many companies are starting to show you to do this.
