Faraday Bags for Phones, Faraday Pouch for Iphone 16/15/14/13/12/11 Series, Google, Android, Cell Phone Signal Blocking GPS, RFID, NFC, WIFI

Definitely works to block phone signals, assuming it does the job for key fobs and cards too. Nicely constructed and sturdy.Obviously ensure the inner dimensions are sufficient to take what you intend to put in, cards and key fobs may not be a problem, but phones could, given the size of them nowadays.

Too small for I phone 11.6.1 inches . Other I phones much larger.

Nice quality faraday pouch, easy to use.Not quite large enough for some of the bigger phones out there? but was a snug fit on a Iphone 12Blocked signals ok as long as you remeber to tightly close the flap.
