My iPhone is stuck in emergency and zoom mode

• Press and quickly release VOLUME UP

     then

• Press and quickly release VOLUME DOWN

     then

• Hold the SIDE button until an Apple logo appears (15-30 seconds), ignoring "slide to power off" if it appears

The operative word here is QUICKLY; and try it a couple of times, the timing is a little tricky. If done correctly this will always work unless the phone has a hardware problem. 

I got a new iphone and i’m trying to set it up but it gets stuck in emergency SOS and i’ve tried to restart the phone but it still doesn’t work. Also my sim card works just fine so i don’t get what the problem is.
