3 Ways to Find Free Unlocking Codes for Mobile Phones

In America, as in several other countries, mobile carriers sell phones with special offers or price cuts. But such phones are also often locked to their network. You can’t swap out the SIM card and use a different carrier’s network.

It’s unnecessarily restrictive, isn’t it? You should be able to use any SIM you want on this phone you purchased legally. And you can. Here’s how.

Is It Legal?

That said, you need to know whether your phone is eligible to be unlocked. The FCC isn’t giving you a free pass to con the carriers. It explicitly states that you can unlock only “after you have fulfilled the applicable service contract, completed the device installment plan or paid an early termination fee.”

Unlocked phones also help tremendously when you’re travelling abroad. Land in any country, buy a local SIM card, and use it. It’s going to be much cheaper than racking up international call and data charges.

Finally, unlocked phones are excellent backup devices. Whether your main phone isn’t working, or someone needs to borrow a device for a few days, an unlocked device gets the job done.

What Unlocking Does and Doesn’t Do

It’s pretty simple. SIM unlocking a phone is only about letting you use any SIM card from any carrier, as long as it is compatible.

Ways to Unlock Phones for Free or Cheap

So, let’s say you have a locked mobile phone, and want to get it unlocked. You want the safest and least expensive way possible, of course. Here’s what you can do.

1. Go to the Carrier

The first and best route is to go to the carrier. If you are eligible to unlock your phone, then it’s completely free!

The FCC says: “Participating providers may not charge existing or former customers additional fees to unlock a device if it is eligible to be unlocked. Providers may charge a fee to unlock eligible devices for non-customers and former customers.”

Here’s how to check if your phone is eligible to be unlocked:

If your phone is eligible, then either request to unlock it online or go to a store. Here are the direct links to contact each carrier:

  • AT&T
  • T-Mobile
  • Verizon: Contact Verizon at *611 from your Verizon Wireless Prepaid phone, or (888)294-6804.
  • Sprint: Contact Sprint Customer Care by dialing *2 from your Sprint phone, or call 888-211-4727

2. Get an Unlock Code Online

Ideally, you should unlock your phone through the carrier. But if you aren’t eligible by their terms and still want to unlock it, you’ll need to get it done via a third party. But it probably won’t be free.

Note: This method is a little iffy to use with iPhones now.

But what if you bought it through your mobile carrier? Read More , and we suggest you follow that.

The internet is full of websites that sell unlock codes. Depending on the country you are in, the manufacturer of the phone, and the carrier you use, you should expect to pay up to $30. Don’t spend any more than that if the seller asks, because you will find it cheaper elsewhere. You can get some codes for as low as $10.

We checked online reviews and testimonials to find sites that usually work, and offer refunds in case the code didn’t work. Here are some of the best:

While all of these are paid websites, you can get free unlock codes on Free Unlocks. This site is a part of the TrialPay network, by which you can get the first code from the site for free. You will need to sign up for TrialPay as a part of it, of course.

Online reports show customers of Free Unlocks repeatedly got the free codes, and successfully unlocked their phones.

    Good tips. But how to find a free unlocking code? The only way is to contact the carrier. If you use a service you will most likely have to pay. I use attunlocker.us for At&t codes but if the phone is under contract you will probably be out of luck.
