What are the hours and when should I call?

DexCom operates the call center for this 888-738-3646 phone number 24 hours, 7 days. The short answer is that you should call on a Thursday. This observation and the following section are based on analysis of a sample set of 348 calls made in the last 90 days using our free, web-based phone (see above).

Automatically call when they open

When you use our free AI-powered phone to call and talk, wait on hold, or navigate for you, it will automatically wait until the DexCom call center opens before trying to call. It will ask your permission before it places the call, so you can also further delay that scheduled call until you are ready. But that means you can "set it and forget it" ahead of time.
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this DexCom phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like DexCom staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy time to call

The least busy day to call DexCom is Saturday. The most busy day to call is Monday, which averages 163% more phone calls by comparison. Again, this is based on a sample of 348 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Monday. The longest wait in the queue on average occurs on Thursday.
But if you use our free call and talk for me or wait on hold for me service, you don't really need to worry about average wait times.

The best time to call DexCom

In summation, the best day to call DexCom is Thursday.

Why Customers Call DexCom

If you have time to do a bit of reading before you call DexCom, we recommend you read over some of our problem-specific articles.

What is DexCom?

DexCom is a leading company specializing in the development and manufacturing of glucose monitoring systems. Our innovative technology enables continuous monitoring of glucose levels in people with diabetes, helping them manage their condition effectively. DexCom's primary product is the DexCom Continuous Glucose Monitoring (CGM) System, which consists of a small sensor placed on the skin that measures glucose levels in real-time. This information is then wirelessly transmitted to a compatible device, providing users with valuable insights and alerts about their glucose trends and patterns. By allowing individuals to monitor their glucose levels without routine fingersticks, DexCom CGM empowers better diabetes management, helping users make more informed decisions about their health and ultimately improving their quality of life.

How does DexCom CGM work?

DexCom CGM, or Continuous Glucose Monitoring, works by measuring glucose levels continuously throughout the day and night. The system consists of a small sensor inserted under the skin, a transmitter that sends data from the sensor to a receiver or compatible smart device, and a mobile app for viewing glucose trends. The sensor detects glucose in the interstitial fluid and sends real-time measurements to the receiver or smart device, allowing users to track their glucose levels without the need for frequent fingersticks. The readings are displayed on the device's screen or mobile app, providing users with immediate feedback on their glucose levels. DexCom CGM helps users make informed decisions about managing their diabetes by alerting them to high or low glucose levels, helping to prevent dangerous fluctuations and improve overall glucose control.

What are the benefits of using DexCom CGM?

Using DexCom CGM (Continuous Glucose Monitoring) offers several benefits. Firstly, it provides real-time glucose readings every five minutes, enabling users to monitor their blood sugar levels continuously, leading to better diabetes management. This accurate and timely data assists in making informed decisions about insulin dosing, nutritional intake, and exercise. DexCom CGM also reduces the need for frequent fingerstick testing, as it eliminates the need for a manual glucose meter. Additionally, it allows for customizable alerts, notifying users of high or low glucose levels in real-time, providing increased safety and peace of mind. Moreover, DexCom CGM is compatible with smart devices, offering convenient accessibility and data sharing with healthcare professionals and caregivers. Overall, using DexCom CGM promotes improved diabetes management, enhanced safety, and a more integrated approach to diabetes care.
