AT&T have announced that they will no longer support email to sms messages as of June 15, 2025. Our system uses this service for all notifications to users on the AT&T network. This includes mobile subscribers to AT&T, FirstNet, and Cricket. As a result, notifications will stop working at that time for a substantial number of Second Signal users.
While there are alternatives to send notifications to our mobile users on this network, transitioning to these alternatives would require us to nearly double our subscription pricing. At this time, many of our customers do not have the budget to continue service.
We deeply regret the loss of this valuable service.
All subscribers who have pre-paid for services beyond June 1st, 2025 will be refunded the portion of services for any period after that time.
For more information on AT&T's announcement, please see their article here.
Information needed to set up Second SignalOnce you've completed and returned the Customer Agreement and you've got the required equipment set up, we'll be ready to set up and configure Second Signal for your department. The most important thing you'll need is the "Tone Configuration" for your department. Second Signal is triggered the same way your pager radios are triggered now When you program your radio pagers, each pager is told to "Alert" on a specific tone set. We need that information. For example, a typical department may have a "Fire" tone and an "EMS" tone. Each of those will have a pair of audio frequencies or "Reeds" associated with them. Typically, the format we're looking for is: FIRE: (A) 313hz (B) 459hz EMS: (A) 652hz (B) 1097hz Some paging systems may use a single long tone, others may use a combination of long and short tones. If you're having trouble finding this information, give us a call and we may be able to help. In some cases when this information is not available, you can send us a recording of the tones going out and we can identify them on our end. In other cases, our software can be set up to "trap" the tones as they are used and make a best estimate.
