We will not be liable for delayed or undelivered SMS messages. Delivery is subject to effective transmission from your network operator and processing by your mobile device. SMS message services are provided on an as is, as available basis.

Wireless carriers are not responsible or liable for delayed or undelivered SMS messages. Emergency services may not be available in all areas. Alerts sent via SMS may not be delivered to you if your phone is not in range of a transmission site, or if sufficient network capacity is not available at a particular time.

Even within a coverage area, factors beyond your wireless carrier's control may interfere with message delivery. These can include but are not limited to the customer's equipment, terrain, proximity to buildings, foliage, and weather.

By opting in, you acknowledge that urgent alerts may not be received on time and that your wireless carrier does not guarantee that alerts will be delivered.

Resolver’s emergency notification system offers SMS texting in several countries. Due to the varied restrictions in specific countries, SMS service, either one or two way, may not be possible. Information about the countries and direction (one-way or two-way) currently supported by our standard notification service can be found here. If you require service in a country that is not listed, please contact your CSM to determine applicability. Additional fees may apply for added country support. 

Please note, not all carriers in each country are supported. Some carriers may vary in directional support. Please contact your CSM with any questions.

We encourage you to test regularly at each of your locations as carrier restrictions change frequently.
