When he switches it on, it immediately says "SIM not registered", allthough it works flawlessly in his HTC P3600 smartphone. Has anybody observed similar behaviour with Samsung handsets? regards, Inquisitor terminals: Samsung: Galaxy S5 DuoS (G900FD); BLU: Win HD LTE; Nokia: 1200; Asus: Fonepad 7 ME372CG; Huawei data: E3372, Vodafone R201, K3765, E1762; postpaid: O2 on Business XL; prepaid: DE: Aldi Talk, Lidl; UK: 3; BG: MTel, vivacom; RU: MTS; RS: MTS; UAE: du Tourist SIM; INT'L: toggle mobile VoIP: sipgate.de (German DID); sipgate.co.uk (British DID); ukddi.com (British DID); sipcall.ch (Swiss DID); megafon.bg (Bulgarian DID); InterVoip.com
