How to get your phone SIM unlocked
Unlocking your phone is just as straightforward as when you enter a code. However, it is imperative to have adequate knowledge on your phone before you can unlock your phone SIM.
Is your phone already unlocked?
This is the starting point as a lot of new phones have already been SIM unlocked, even if you get it from a carrier.
Some phones are sold as unlocked, unlike a Pixel phone and some brands of iPhone, Samsung, HTC that are bought from eBay or Amazon or the company that manufactured it as an "international version."
While it's not every company that wants to sell locked phones, some others actively advertise themselves as solutions to locked.
Check if your phone is locked or not before you make any further attempt.
Verizon phones are also usually network unlocked as they use a network configuration which does not have user-accessible SIM card for 3G data (CDMA) and voice but they use a standard SIM card for the 4G LTE connection.
The agreement Verizon had with the U.S. government made the former to lease the spectrum they use for LTE, so they do not block any device from the use of that network part.
This led to the sale of unlocked phones. Even though Sprint is extricated from these regulations, they also sell some phones that have been unlocked. Others will require to be opened the "usual" way.
Some of the so-called usual way is the use of free sim unlock, free IMEI unlock or free phone unlock service that can be found online.
It is noteworthy that while a phone from Sprint or Verizon may be SIM unlocked, it still doesn't guarantee its compatibility with an MVNO, AT&T or T-Mobile.
While some may, others may not, and some require a bit of hackery because of the locked APN. This will require the owner of the phone to look for a way to unlock the sim, IMEI or phone to bypass the locked status.
There are free or paid sim unlocking services online that offers this kind of thing. Most phones sold at the AT&T or T-Mobile store are SIM-locked to their network.
The same also goes for Canadian carriers.
Your carrier can unlock your phone
Use of an unlock code
This is the best method to get your phone SIM unlocked. It works thus:
U.S. and Canadian laws declare that a carrier has to unlock your phone once you fulfill some specific requirements. To start the process, inform your carrier you will require them to unlock your phone. Once you've satisfied their spelled-out requirements, you will be given an unlocking code. Insert a SIM card for a distinct network in the phone, and it will request for that code. Input it (sometimes you might need a reboot), and the phone should recognize the SIM. You don't have to use your SIM card for unlocking compulsorily; you can get a friend's own.
You can even do all this through a carrier app that has been installed on your phone, so it is advisable to check if you'd instead not call anyone.
You might need to insert network (APN) settings for the new network, but some "big" network operators usually have an APN setting in the system software that is automatically used.
However, your carrier might withhold any form of help to unlock your phone. There are some rules about those qualified to get an unlock code. If you fall under any kind of finance contract for the phone, you may be denied an unlock code. While these rules differ from carrier to carrier, universally, you will be required to have a good standing account, have had the phone for a specific length of time, and any other thing considered a good reason for the network getting your phone unlocked. You can always consider another option. Some of this option is safe and easily accessible, plus they offer free sim unlock, IMEI unlock or phone unlock.
Use an unlocking service
Some companies purchase network unlocked codes in large quantities from carriers, then resell them to the general public. Though done legally, this grey area changes annually (based on the whims of people such as the Librarian of Congress). You only have to use the service they offer.
Free IMEI/SIM Unlock
The orders you place in free service often have low success rates, take longer to get unlocked and have limited slots daily. If you need your mobile phone unlocked as fast as possible and with guaranteed success rates, consider the paid service. In case you have placed your order previously in free service, and you couldn't find a code, then you will be unable to resubmit your request, and you can only get it unlocked using paid service. A premium service gives you peace of mind and 100% chance of a working code; anything else is money back guarantee. Promptly click on the "Unlock Phone" icon to place the order of your choice.
