sim holder for iphone 4s 5.0.1 1. dual SIM CARD 2. STK MENU SIM ADAPTER FOR IPHONE 4S 5.0.1 DescriptionThe Phone 4 can do plenty, even play nicely on other GSM networks, but up until now you couldn’t put two SIM cards inside it.  Our dual SIM Adapter Case doesn’t quite change that – the two SIMs in question aren’t exactly within the Phone – but it does allow you to easily flip between cards without reaching for the Liquidmetal tool. That’s because each SIM clips into a special adapter that then snakes round the side of the Phone 4 and into the regular SIM tray.  A transparent plastic shell keeps everything safely in place, and there’s no need to cut the cards beforehand.Now, you can’t have both SIMs active at the same time – that’s a limitation of the Phone , sadly – but you can apparently switch between them without having to reboot the phone.  According to our sim, you can simply pick the correct card from the SIM Applications menu in the Phone ′s settings, and after a minute or two it flicks over.   ================English Menu======================================Three SIM CARD*SIM1SIM2SIM3*Auto SWSetup-----  SIM1 No.            SIM2 No.            SIM1 time:003            SIM2 time:003PLEASE CONTACT US FOR DETAILED RIGHT PICTURE AND FEATURES.
