(call) lose connection
If a call or connection drops out, it suddenly cuts off because the signal is weak.
Hear it in context
Notice where the phrase sounds natural.
Sorry, you dropped out for a second there — can you say that last bit again?
The call keeps dropping out — I think I've got a really bad signal here.
Fix the pattern
One small grammar move makes it sound right.
Not: You're dropping off, I can't hear you.
Say: You're dropping out, I can't hear you.
For a bad signal it's 'drop out' (or 'cut out'); 'drop off' means fall asleep.
