Nothing kills a conversation faster than a sudden drop in signal. Use 📞🔊❗ to warn friends of choppy calls, or 📱📵⚡ when your phone is acting up mid-text. The combo 📱❌🔌 nails that powerless moment, while 📞📶🚫 and 📱🚫🔊 express full-on blackout vibes. These fit well in group chat rants, emergency updates, or those frustrating 'Can you hear me?' moments.
