Region locked Samsung devices. SII, SIII, S4, Note, Note3 etc. Not just Note 3.
I found this on www.pocketnow.com and on many EU sites... So it is confirmed.Here is what Samsung has to SAY:The company clarifies exactly which devices fall under this restriction, explaining, "the regional SIM card lock only affects the following Samsung models that are produced from the end of July 2013, and provided with a corresponding sticker: Samsung GALAXY S III, II, GALAXY Note, GALAXY S4, S4 GALAXY mini and the GALAXY Note 3"So not only the Note 3 is affected but most popular Android devices made by Samsung.
