Review on 🔒 LVFEIER Security Pouch - All-in-One Cell Phone Privacy Protection Solution by Samantha Cameron

When I put my cell phone in this bag, it no longer rings. Not sure if this is true EMI protection as my car still recognizes my key when I put it in my pocket. I wonder how that can happen if it blocks electromagnetic fields. It seems that this case can actually only block the sound, unless the EMF from car keys is transmitted differently than the EMF from cellphones. I think I'll try something different now.
