Sensors come pre-installed with our global simcard and work around the world automatically.Plans cost $4.20 monthly or $46.20 annually (prepaid annual plans save 8% and total $3.85 per month). Each plan includes unlimited alerts with no contracts, and you may cancel anytime for any reason. Every sensor includes 30 days of free alerts without a credit card and we offer a full refund within 30 days if you're not satisfied. Data plans are purchased in the Simtek app after the free trial ends. If you upgrade before your free trial ends, unused trial days go into your plan so you don't lose them.Alerts are sent over encrypted cellular connections.
