Rainbuvvy K05 4G Smartwatch: 4G connectivity
But wait, there's more (because of course there is):
- It's tough as nails with an IP68 waterproof rating – rain, sweat, or accidental dunks, it can take it.
- Power through your day with a 650 mAh battery and juice up in no time with 30W fast charging (because nobody's got time to wait).
- Bluetooth keeps everything connected smoothly, because tangled wires are so last century.
- Pop in a Single SIM and go solo – your phone will miss you, but you'll be just fine.
- Runs on Android OS, so it feels like home right from the start.
