How do I tell if I have a 3G or 4G device?

All 4G PumpAlarms look like the image below. If your device does not have a yellow cover and say “4G/LTE” on the bottom right of the cover, you do not have a 4G device. If you do not have a 4G PumpAlarm, you should upgrade your device before the 3G sunset scheduled for December 31, 2020.
