SMS Messaging Terms & Conditions

Effective Date: June 1, 2026

1. Program Description

The Signetik Device Monitoring SMS program ("Program") is operated by Signetik, LLC. The Program sends automated SMS text messages to opted-in users regarding the operational status and fault conditions of IoT devices registered through the Signetik device setup process. This is a transactional/operational messaging program; it does not deliver marketing or promotional content.

2. Eligibility and Consent

To participate in the Program, you must:

• Be the owner or an authorized user of a Signetik-compatible IoT device
• Possess a valid U.S. mobile phone number capable of receiving SMS messages
• Initiate the opt-in process by entering your mobile number via the device serial terminal command +set,smsnum:[your number] and confirming consent via +set,smsapprove:1

By completing the opt-in process, you confirm that you are the account holder or have the account holder's authorization for the mobile number provided, and that you agree to these Terms & Conditions.

3. Message Content and Frequency

Messages sent through this Program will relate exclusively to:

• Device status updates and heartbeat confirmations
• Fault condition alerts and diagnostic information
• Service notifications directly related to your registered device

Message frequency: expect 1-4 messages per day under normal operating conditions, and up to 10 messages per day when fault conditions are detected. Message frequency may vary.

4. Costs

Signetik does not charge for SMS messages sent through this Program. However, standard message and data rates from your mobile carrier may apply. Contact your carrier for details about your plan's SMS rates.

Consent to receive SMS messages is not a condition of any purchase of Signetik products or services.

5. Opt-Out

You may cancel SMS messages at any time by replying STOP to any message received from this Program. After texting STOP, you will receive a single confirmation message and no further messages will be sent to that number unless you re-initiate the opt-in process. You may also opt out by initiating a new number setup on your device, which clears the previous approval, or by contacting Signetik support directly.

8. Accuracy of Information

You agree to provide an accurate mobile phone number during the opt-in process. Signetik is not liable for messages sent to a number provided in error. If you change your mobile number, you must update your device registration accordingly.

9. Disclaimer of Warranties
