A: No. It also serves UK customers (though Brexit has complicated this) and some other EU countries where Samsung lacks a local return hub. Always check your shipping label.
If a device is locked to a network (e.g., Vodafone, Three) and the user requests a "Sim Unlock" code directly from Samsung, the request is processed administratively. While most unlocks are digital, formal disputes regarding unlock eligibility may require written correspondence to this PO Box. Samsung Po Box 12987 Dublin Ie Imei
