Can I use a 3G or 4G Hot-Spot for connectivity?

Yes. Particularly, there are cases where you have limited or unstable network connectivity. In these cases, you can bring your own, dedicated Hot-Spot to enable fast connections for 5+ devices simultaneously. Also, there’s a growing number of such low-cost devices with month-to-month connectivity plans.

Notably, each codeREADr scan only posts 1kb of data up to the server and 1kb of data back to the device. Therefore, total data usage is quite low.
