What happens if my SOS contact’s misses the initial Alert?

We send reminders out to the SOS contacts, after 5 minutes and 10 minutes if no-one has taken responsibility.

This solves the problem of someone missing the initial alert.

See example below: 

The alert is an SMS, the first one is the initial alert with a link to the location.
Then 5 minutes later a reminder was sent.
5 minutes later, now 10 minutes, a third reminder is sent.

If the SOS contact is also set-up to receive phone call alerts they will recieve the initial call and then the reminder calls at 5 minutes and then 10 minutes too.
