Ok so i just received a lg velvet and had an iphone 10
My sim card dont fit in the new phone so do i need to order a new one and transfer my number and all?
Nano SIM card, the same as your IPhone and a micro memory card ( optional-sold separately )
I thing they both use nano SIM card
Check on you tube how to put my nano SIM card and micro sd for a lg velvet
our iphone use a nano sim card
Check this link
There is place for 2 card, one for your nano SIM card an another for a micro memory card
LG phones are quite known for having "tight" trays. Your LG phone uses the same nanoSIM card as your older iPhone. You will need to install it by looking at your user's manual. It is usually hard to fit in, but give it a few tries...
Yep it should fit... push it gently
