How To Unlock A T-Mobile Phone For Free

Have you ever been concerned about your monthly phone bill? Do you ever notice extra charges on top of your mobile contracts, or get frustrated when you go overseas and have to use expensive texts, crazily-priced mobile data, and eye-watering call charges?

Almost everyone has felt ripped off by their mobile carrier before; it is unquestionably frustrating to be tied by contracts and having a phone locked by one mobile carrier, especially in this technology age when an average person uses their phone for 3-4 hours a day and travel to a few foreign countries a year. Having an unlocked phone allowing you to use any SIM card from any service provider in the world.

An unlocked phone usually carries a higher price tag compared to a locked phone, which prompts many people to purchase locked mobile handsets from mobile carriers, and from there on having to use a phone that would only work with SIM cards from one network provider.

When using your current plan and noticing how costly it sometimes is, you likely to start thinking about switching to a different carrier to get better deals for your phone plan. However, with a locked phone, you must stick to the same provider even when you travel. What many people don’t know is that you can unlock your phone for free thanks to technology. Check out our guide on the 10 best ways how to unlock a T-Mobile phone for free in 2020.

Unlocking a phone can be complicated, as when your phone is locked, the IMEI number of your phone is linked with the SIM by the network provider, and the conventional way of unlocking your phone is through requesting your network provider to unlock it for you. However, there are many more choices nowadays to unlock your phone by yourself for free.

Once you unlock your t-mobile phone free, you are now in control of your phone charges, both local and overseas. There is no longer the need to stick to the restrictions of one mobile carrier, and you can say goodbye to whooping roaming charges. Unlocking your phone now is as easy as going online to a phone unlocking service site, type in your IMEI number, generate the code from the service, and enter it into your phone.

Why Unlock Your Phone?

  • Save hundreds of dollars off your roaming charges the next time you go overseas. There are many cases of misunderstandings of terms and conditions for roaming charges, which lead to phone bills of thousands of dollars.
  • Having the flexibility to choose the mobile plan that suits your needs the most. New plans are rolled out very often and promotions are usually applied for new users of a carrier, hence you can make the most out of what you pay for your phone bill.
  • Ensuring you have a stable connection wherever you go. Every network has its own weak zones where the connection may not be strong enough. Having the ability to switch to any carrier can ensure you have quality phone calls and an internet connection anywhere you go.
  • If you wish to resell your phone, an unlocked phone is much easier to be sold as there is no restriction associated with it. Selling a locked phone automatically narrows down the pool of potential buyers. Or in case you want to give your phone to a family member to use, they do not have to worry about changing their number and carrier just to use that phone.
  • Unlocking your phone using IMEI is completely safe and legal. You are not altering any software or hardware during the process; hence this phone-unlocking method is recommended by phone manufacturers and network carriers.

How to Unlock A T-Mobile Phone for Free

There are two types of phone unlocking services, one is web-based and one is app-based. The web-based services have an advantage over app-based services when it comes to convenience, as you do not have to download and install any software. However, app-based services are reliable and fast, and when you use free software, you only need to download it once for multiple uses.

Although you need to go through the hassle of connecting your phone to your computer using a USB cable when using app-based services, this method tends to be faster than using the website to get the unlock code.

The average time to unlock using the USB cable method is 15 minutes, while that of the IMEI unlock code is 24 hours, due to the waiting time for your code to arrive. Therefore if time is of the essence for you when unlocking your phone, app-based services are the more suitable choice.
