Your phone may be locked if you are under contract with your current carrier or if its not paid off yet. In some cases, a phone might be locked due to the Reseller Flex policy, which allows retailers to sell phones that are initially unlocked, but are programmed to lock to the first network they connect to at activation. You can call your current provider to check if your phone is unlocked or locked; if it’s locked, they should be able to help you unlock it.
