On-off combos nail that flickering vibe of tech glitches and mood swings alike. Try 📶📴 when your signal’s playing hide and seek or pair 🔊🔇🔈 to describe volume battles during a call. When you’re toggling between work and break, 💻🔌🔴 fits like a glove. These emoji stacks work well in post-meeting recaps, status updates, or group chats where someone’s connection just can’t decide.
