Can a phone work without a SIM card? Why or why not?
Well...Let's go with a YES....a phone, that is: the device today known as a smartphone, which employs -in some occassions- a SIM card- can work without a SIM, providing that :If you want to use that device as a phone, cellular phone, then NO, it won't work. It requires the SIM card to be able to "enable" so to say, the actual phone number and then connect and identify itself to a cellular network and ultimately place and receive cellular phone calls.Now, it you want to use that very same device with or without a SIM card for:WiFi based Internet purposes (navigation, downloading pictures, movies, music)...Music listening.Movie / video watching.Pictures taking with the camera.Any internet based communications (hangouts, skype, etc. -WhatsApp may depend on having had, at least once, an operational SIM card tough-)Then your phone WILL perfectly work fine, as all this activities, (except perhaps for WhatsApp activation), do not require, nor depend on a SIM card and the functionality this SIM provides.

Whatsapp chat with people out of my country?
You need to save their phone number in a full international format.
I put someone on my reject list on my Android, so will that mean I won't get any calls or texts from them?
Yes you won't get calls from that numberWhat actually happens after blocking a number your phone automatically reject calls from that number as fast as possible.This means everything blocked caller try to call you he got a busy tone on your number and caller will understand that you have blocked his number and think you are trying to avoid him i was doing same thing with one of my friend and he got that.So i found a solution for that Call forwading. Go to your phone setting →calling account →click on the sim card from where you want to forward calls →select voice calls →Forward when busy .Now enter a number that doesn't actually exist e.g. 1234567890 .Now when blocked caller calls you instead of getting a busy tone he will get a tone saying that ‘number on which you are calling doesn't exist, pls check the number then try again' .This is the best way to avoid someone by blocking him without his knowledge……
