Answer: Asking for it.
Lose your cellphone in the house? If you’re an Xfinity Mobile (from Comcast) customer, finding it may have just gotten a whole lot easier — all you have to do is ask.
Comcast recently introduced a new feature called Phone Finder for its customers with a wireless service plan. Just say “Xfinity Mobile, find my phone” into your X1 voice remote, and your device will be called. You’ll have to specify whose phone you’re looking for if you have multiple lines or give the 10-digit phone number of the phone you want found. If someone else finds the phone before you do, they’ll hear a pre-recorded audio message explaining the reason for the call when they answer.
Just make sure you don’t lose your Xfinity remote too.
