Mobile Phone and Device Unlocking FAQs

Consumers often question why they may not have the choice of using their existing mobile wireless device when they change between compatible wireless service providers.  The answer is usually a practice called cell phone locking and it is about to change.

On February 11, 2014, CTIA-The Wireless Association adopted six standards on unlocking into the CTIA's Consumer Code for Wireless Service.  Implementation of these six standards by major mobile wireless service providers will give consumers greater freedom and flexibility while increasing incentives for service providers to innovate.  Participating wireless service providers will implement at least three of these six standards by May 11, 2014, and all of these standards by February 11, 2015.

Here are several FAQs to help you better understand cell phone unlocking and how it relates to you:

Q: What Is Mobile Phone and Device Locking?
Some mobile wireless service providers use software "locks" on their devices. These locks are meant to ensure that devices can only be used on the networks of specific service providers.

Q: Why Do Providers Lock Mobile Wireless Devices?
In many instances, devices are sold with subsidies (or discounts) in exchange for a required service plan agreement, often months or years in length, or subject to a device installment plan. Most service plan agreements have an early termination clause that includes a penalty to be paid to end the agreement ahead of schedule.  Locking software is meant to ensure that devices will be active for a certain period of time or amount of usage on the network of the provider that sold that device with a subsidy (or discount) or with a device installment plan.

Q: Is My Cell Phone Currently Locked?
Unless you purchased a phone or device specifically sold as "unlocked" at the point of purchase, you should assume that it is locked to a specific service provider's network. This is true whether you purchase the device from a service provider, at a general retail outlet (in person or on the web), or through a third-party.

Q: How Can I Unlock My Mobile Phone?
Contact your mobile wireless service provider. Devices can be unlocked with unlock codes or other software updates provided to you by your provider.  Some providers will complete the unlocking process in-store, others will unlock your device remotely and automatically. 

Q: Are Mobile Devices Besides Phones Locked, Too?
Yes, tablets and other mobile devices can be locked to networks. The new standards cover mobile wireless devices, including tablets.  You should check with your service provider to see if your mobile device is locked and what terms and conditions you have agreed to.

Q: Will My Postpaid Phone Be Unlocked on Request?
Once the new standards are fully implemented: Yes, provided the terms and conditions of your service contract are met and you are in good standing. You should speak with your service provider to understand the terms and conditions of your agreement and the provider's policies on unlocking mobile devices.

Q: Will My Prepaid Phone Be Unlocked on Request?
Once the new standards are fully implemented: Yes, participating service providers have agreed to unlock prepaid devices within one year of initial activation, consistent with reasonable time, payment, or usage requirements.

Q: Which Service Providers Are Implementing the New Standards on Unlocking Mobile Devices?
The website of CTIA-The Wireless Association,, has a current list of signatories to the Consumer Code for Wireless Service, which includes the new standards.  If your wireless carrier is not one of the participating service providers, please contact them directly regarding their device unlocking policy.

Q: When Is My Device Eligible for Unlocking?
Once the new standards are fully implemented, your postpaid device is eligible to be unlocked after you have fulfilled the applicable service contract, completed the device installment plan or paid an early termination fee. Your prepaid device is eligible to be unlocked no later than one year after activation, consistent with reasonable time, payment, or usage requirements.

Q: Will My Phone Automatically Be Unlocked When My Service Contract Has Been Fulfilled?
It depends on your service provider. Once the new standards are fully implemented, participating service providers will notify you at the time your postpaid device is eligible for unlocking if the device is not automatically unlocked. For prepaid devices, participating service providers will notify you when your device is eligible for unlocking at the point of sale, at the time of eligibility or through a clear and concise statement of the provider's policy on its website. When your device is eligible, some service providers may automatically unlock it remotely. In this case, providers of postpaid devices are not required under the new standards to notify you at the time when the device is eligible for unlocking.  Other providers may require you to formally request to have your phone unlocked. Under the new standards, providers have agreed to unlock eligible devices, provide you with unlocking instructions, or initiate an unlocking request to the device manufacturer – or provide an easily understood explanation of denial – within two business days of receiving an unlock request.

Q: Will I Be Charged Fees to Unlock My Device?
Once the new standards are fully implemented, service providers may not charge customers and former customers additional fees to unlock a device if it is eligible to be unlocked. Providers may charge a reasonable fee to unlock eligible devices for non-customers/non-former-customers.

Q: Are There Military Exceptions to Allow Device(s) to Be Unlocked Early for Deployments?
Yes. If you are deployed internationally or receive orders for international deployment, providers must unlock your device upon verification of deployment under the new standards.  Contact your mobile service provider, provide verification of your deployment, and request that your device(s) be unlocked.

Q: Can My Mobile Service Provider Refuse to Unlock My Phone Because I Owe Them Money or Am Currently Under Contract?
Yes.  Providers do not have to unlock devices for customers or former customers that are not in good standing.  You should contact your mobile service provider to understand the terms and conditions of your agreement and your provider's unlocking policies.

Q: Will My Unlocked Mobile Device Work on All Networks?
No. Network technology (GSM, LTE, CDMA, etc.) varies between different regions globally and across the United States. Device technology varies to ensure it works with compatible networks. In other words, your device technology must be compatible with network technology to enable access and functionality. Because the technologies differ, your device will not work across all networks.

Also devices are optimized to work with service providers' networks for which they're sold. Although your mobile device may work on a compatible network, certain features on your unlocked phone may not work optimally, and some features may not work at all.

Q: Will Unlocking My Device Enable It to Work on International Networks?
Whether your device is locked or unlocked, you should check with your mobile service provider before you travel internationally. Find out if your mobile device will work abroad. Mobile networks differ from country to country, and your device may be incompatible with the networks where you are traveling. Also, if your phone works for voice calls, some other functions – such as sending and receiving mobile data or text messaging – might not work.

International roaming is complicated. Take time to understand all the rules and rates before you travel. Advance preparation can prevent disappointments such as lack of service or unexpectedly high charges on your next bill.

If your smartphone is capable of using one, you might consider buying a "SIM" card (the removable card used by some mobile handsets containing subscriber data and the phone's number) with a local number in the country you are visiting, effectively turning the handset into a local phone.  However, you should check with your carrier to determine whether your device can utilize international SIMs.
