Frequently Asked Questions


  • General Overview
  • Soberlink Cellular Devices test for the presence of alcohol in human breath and use facial recognition to confirm identity during each breath test. BAC results are wirelessly transmitted in real-time via Verizon’s Private Network to Soberlink’s cloud-based recovery management software. Sober Sky Web Portal allows clients to customize notification and automated report settings for specified Contacts.

    No. Currently, Soberlink only detects the presence of alcohol.

    The Soberlink Cellular Device is the only remote alcohol monitoring system cleared by the FDA. Since 2011, Soberlink has been the leader in real-time, remote alcohol monitoring with solutions for court ordered monitoring, child custody monitoring, and recovery management monitoring. Soberlink’s robust tamper detection, reliability, and proven track record separates itself from other alcohol monitoring systems.

    The Soberlink Device contains a professional-grade fuel-cell sensor with a detection range of 0.000% – 0.400% BAC and accuracy level of +/- .005 BAC. The fuel cell that Soberlink uses is globally trusted and used for high-end workplace and law enforcement breath alcohol instruments.

    The electrochemical fuel-cell sensor generates an electronic response that is proportional to the Breath Alcohol Concentration in the provided breath sample. The fuel-cell sensor is specifically designed for detecting alcohol. It does not respond to acetone or other substances that can be found in human breath.

    Soberlink’s system uses Adaptive Facial Recognition™ (AFR™) technology to verify the identity of the client during each breath test. Contacts can be enrolled to receive a real-time Alert if the tester’s identity cannot be confirmed.

    Queuing or storing is a feature that allows the Soberlink Cellular Device to store and later upload tests if there is a lapse in connectivity. For example, if a test is sent from an area without sufficient cellular coverage, the test will be time stamped and stored, then when cellular coverage is restored the test will be automatically uploaded to the Sober Sky Web Portal. If real-time results are imperative for concerned parties, like child custody/family law monitoring, it is recommened that queuing/storing be disabled.

    The Soberlink Cellular Device transmits data on Verizon’s Private Network which provides coverage only within the United States and Canada.

    For the most accurate results, breath tests should be taken in temperatures between 32°F and 122°F. If the test is attempted outside of this temperature range, the Soberlink Cellular Device will not send the test result and will display a warning that the Device is too cold or hot.

    Soberlink Devices are equipped with several proprietary technologies that are able to detect if a breath sample is consistent with the properties of human breath. If a breath sample is flagged as inconsistent with human breath, it will be reported to the specified Contacts.

    Even though the fuel-cell sensor can stay accurate for many years, it is recommended by Soberlink to exchange the device at 1,500 tests. All Soberlink Devices have an internal test counter that will begin to send Alerts to Clients as the Devices nears 1,500 tests.

    No. Soberlink does not believe that random testing is the best way to use the system. Although random testing is the norm for urine testing, scheduled daily testing creates structure and accountability, while reducing testing anxiety. This can be especially important for people in early recovery.

    Avoiding incidental exposure to alcohol is simple – don’t eat, drink, smoke, or interact with products that might contain ethanol 15-20 minutes prior to testing. This is the same protocol used in road side sobriety testing. We also recommend rinsing out your mouth with water prior to testing. The Soberlink System is unique because it includes a Retest cycle. In the event of a positive test, the Client will be prompted to retest every 15 minutes until they are compliant. Incidental exposure to alcohol from things like mouthwash, should dissipate within 15 minutes and the retest should result in a compliant .00 BAC.

    Studies show elimination rates can vary dramatically from person to person. Even the same person can have varying absorption rates from day to day. Dr. Alan Wayne Jones, a top forensic toxicologist and researcher, found people fall in one of the following groups:

    Group Type Expected Rate of Elimination (per hr.)
    Slow elimination rate .008 – .012
    Moderate elimination rate .012 – .015
    Rapid elimination rate .015 – .025
    Ultra-Rapid elimination rate .025 – .035

  • Soberlink Monitoring Web Portal
  • The Sober Sky Web Portal allows Clients customizable options for a unique testing schedule. A “Scheduled” test is accompanied by a variable Test Window. A Scheduled Test can be submitted anytime within the selected Test Window – starting 15 minutes before the test time and ending after the selected variable testing time. Test Windows can be customized for 1-hour, 2-hour, 3-hour, or 4-hour durations.

    For long-term use of the system, the suggested testing window is 2 hours. Once a Test Window is selected, it will apply to all scheduled tests for that particular Client. However, the Client can send a test at any time. If a test is submitted that was not scheduled through the web portal, it will be labeled as an “Unscheduled” test.

    In order to receive the text reminders, the Client’s personal mobile number must be entered into the Sober Sky Web Portal by Soberlink or by a Service Provider, and the Client must respond as prompted to the initial opt-in text message. Based on each scheduled Test Window, automated text messages will be sent to the Client’s mobile phone, reminding them that a scheduled test is coming up.

    If the Client tests positive, or does not submit a test within the Test Window, a separate feature called “Alerts” will notify previously specified Contacts with automated email and/or text message notifications.

    In the event of a Non-Compliant test, the Soberlink Device will display a message for the Client to Retest in 15 minutes. If the Client is opted-in for text notifications, they will also receive a text on their mobile phone prompting them to retest. If additional Non-Compliant tests follow, the Client will continue the Retest cycle and be prompted via text message to Retest every 15 minutes until a compliant test is submitted, or 3 hours has elapsed. Contacts can be set up on the Sober Sky Web Portal to receive immediate email and/or text Alerts following positive or missed tests.

    Soberlink is not currently covered by major health insurance carriers, but the Soberlink System does qualify for Flexible Spending Arrangement (FSA Reimbursement). Please check with your employer about your FSA program.
