A couple days ago there were launched international sales of new flagship smartphones of Samsung, namely Galaxy S7 and its greater brother Galaxy S7 Edge. The devices are already available on the store shelves in the USA, Europe, Australia, Singapore and South Korea. If you plan to purchase the new gadgets in Europe, you should know that Samsung has been practicing regional blocking for a few years now.
Thus, if you buy a Galaxy S7 (model index SM-G930F) or Galaxy S7 Edge (model index SM-G935F) in Europe and then travel to another region and insert a local SIM card, your smartphone will refuse to connect to the network. This is stated in small print on a special sticker on the box.
Such a “protection system” is installed in all European Galaxy S7 / S7 Edge, including ones that come without binding to a certain mobile carrier. This is done in order to prevent transportation of devices to other regions for subsequent unofficial resale.
After buying a new Galaxy S7 or S7 Edge in Europe, you should first of all insert a SIM card of a local carrier and accomplish a five-minute call (one call lasting five minutes or five calls lasting one minute each). Only after you complete this, the smartphone will be fully unblocked and usable with any other SIM card.
