Hello !
I've bought an Iphone 5 and i've unpacked it switched on procceded to activate it forgot that the sim card is necessary and ill have to wait till tomorrow till ill get a nano one so all i wanna ask is is it better to switch off the iphone until ill get the sim or let it be in the standby mode ?
Im asking only because i want to have a good battery life in the future
