A general phone question ?

I see here and on other forums -- when people post --- at the bottom --

"Sent from my "whatever cell" using Tapatalk"

A - Can that line be defeated ?

B- Does it bother you all that you're giving free advertising for a product that you already pay for ?

When I get an incomeing call - just before my ring tone --

"Verizon Wireless" --- I really hate that

Let's block ads! (Why?)
