It depends on your service provider. Participating 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 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 providers may automatically unlock it remotely. In this case, providers of postpaid devices are not required under the adopted 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 adopted standards, participating 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.
