I've been told by another carrier that Sprint needs to unlock my SIM slot in order to use my phone on the other carrier's network.
For eligible devices, Sprint will unlock the SIM slot, to the extent that a device SIM slot is capable of being unlocked. It is important to note that not all devices are capable of being unlocked, often because of the manufacturers' device designs, and that even for those devices capable of being unlocked, not all device functionality may be capable of being unlocked.
Specifically, devices manufactured with a SIM slot within the past three years (including, but not limited to, all Apple iPhone devices), cannot be unlocked to accept a different domestic carrier's SIM for use on another domestic carrier's network. Sprint has no technological process available to do this. In accordance with Sprint's voluntary commitment contained within CTIA's Consumer Code for Wireless Service (“Unlocking Commitment”
, Sprint is working to ensure that all devices developed and launched
on or after February 11, 2015 are capable of being unlocked domestically.
If my device is unlocked, does that mean I will be able to use it with a different carrier?
Even if unlocked, Sprint devices will not necessarily work on another carrier’s network. Whether an unlocked Sprint device can be used on another carrier’s network is subject to that carrier’s policies and network compatibilities.
Even if a different carrier will activate a Sprint device on its network, Sprint does not make any guarantees as to a Sprint device’s performance on another carrier’s network or that any or all device features or functionalities will be fully or partially operational. Although a phone manufacturer may manufacture the same device model and name for different wireless carriers offering wireless service in the United States, Sprint devices are specifically designed to function on Sprint’s network and Sprint’s frequencies and technologies.
Sprint’s unlocking policy appears to apply only to postpaid customers. I am a prepaid customer. Am I eligible to have my device unlocked?
Neither Sprint nor its prepaid affiliates (Virgin Mobile, Boost Mobile, and Assurance Wireless) currently unlock devices for prepaid customers. However, in accordance with the Unlocking Commitment, Sprint and its prepaid affiliates are working to create new policies and procedures in order to unlock prepaid devices, or to provide the information necessary to unlock the devices, after certain eligibility requirements to be established are met. Consistent with the Unlocking Commitment, Sprint and its prepaid affiliates will implement these new policies and procedures no later than February 11, 2015.
