Easy way to protect a phone. Go to some cheap appliance store or Waimart etc and look for a very small ‘microwave’...
Take two phones with you or a friend with a phone.
Put your phone in the small microwave and ask your friend to dial your number.
If the phone rings in the microwave move on to the next one...and repeat.
Here’s one for less than $60 on Amazon:

If the microwave is functioning as a faraday cage the phone inside won’t ring.
For larger things - chicken wire works better than solid metal - that’s the rumor...
