The US Reseller Flex Policy, also known as SIM OUT, allows retail stores to sell devices that have not yet been locked for use on a specific US cell carrier. However, these devices are programmed to lock to the first US carrier they connect to after inserting a compatible SIM card.
For example, if the first SIM card inserted is from Verizon, the device will function exactly as if it was bought directly from Verizon, and the device will be locked to Verizon.
In addition, the first SIM card put into the device MUST be from a US cell carrier. If the first SIM card is not one from a US cell carrier, the SIM card will not be activated on that device.
Due to how these US Reseller Flex Policy (SIM OUT) devices lock to the first cell carrier’s SIM, they cannot be listed in the Unlocked category here on Swappa. If a seller wishes to list a device sold to them using the US Reseller Flex Policy, they must choose a specific US cell carrier in which to list the device.
