How many simcards can be used in iphones? particularly apple iphone?

One one sim card can be used in iphone. No dual sim option.

You can use an iPhone's activated SIM card with another AT&T carrier locked phone or with an unlocked phone, but in order to use the SIM card from an iPhone with another iPhone, you need to activate the SIM card with the iPhone. The SIM card is "married" to the iPhone's IMEI number, and the only way to do that is via the iTunes activation process.

You can use as many sim cards as you want in the iPhone but only one at a time.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
