Question about duplicated SIM Cards?

demonassassin11

    Heyy guys, I was wondering if I'm about to request for a duplicated sim? also, let's say I have a second phone and I wanna use it for emergencies. I transfer the duplicated sim to that phone, would it allow the use of LTE? would it mess with my personal phone?

     

    I just want my emergency phone to have LTE/Internet so it has a way of contacting whoever it needs to.
