What happens if you take out your SIM card and put it in another phone?

Yes, If you put your sim card in another phone, your number will remain the same. As long as the sim card is compatible with the phone – meaning that the phone is unlocked or locked to the same carrier as the sim card – then, you will be able to use the sim on the phone with the same number.
