Method 1: Remove Battery and SIM Card

Most of phone’s battery now cannot be removed from phone. I thought it is more durable than traditional phone but I was wrong. Anyway, my statement has nothing to do with the sim card. Good to know my sim was working fine yesterday when I connected it to the internet.

Good to know.
