Connectivity Pricing

LTE mcAir
Cloud access $0.99 per device per month $0.49 per device per month
Data $0.20 per 1000 messages $0.02 per 1000 messages

Monthly Cost Calculation Example

You can calculate how many messages you need per month by dividing 43200 by your messaging interval in minutes.

A LTE device sending every 15 minutes (~3000 messages a month) would cost $1.59 per month.

1*($0.99 + 3($0.20) = $1.59
