If the pouch is fully sealed, then the product’s nickel and copper barrier totally blocks the phone of receiving the signal and data. You’ll get the best functionality with pure ease of use. Place 1, or even 2 phones in the open pouch, the signal will still be present (coming from the top down, going only up), so radiation will be blocked in all directions towards the body (downwards and outwards at the sides).

RECOMMENDATION:

The top edge of the box should be placed above head level for the most effective protective action during sleep.
