Are unlocked mobile phones (of the same model) more expensive than mobile phones that are not unlocked?
yes, typically. unlocked phones can be used with pretty much any sim card as long as it works with the GSM. locked phones only work for one carrier. i.e verizon, sprint, etc. example, a sidekick might cost $50 with a 2 year plan yet it would cost probably around $150-200 to buy it unlocked.
