One Call Alert vs. MobileHelp

One Call Alert and MobileHelp are both medical alert systems designed to provide assistance to seniors or individuals with medical conditions who may require emergency help. One Call Alert offers a range of products including a wearable device and a home base station, whereas MobileHelp primarily offers wearable devices with GPS tracking capabilities. One Call Alert’s home base station provides a range of 1,000 feet, while MobileHelp’s wearable devices have a range of up to 600 feet. Both companies offer 24/7 monitoring services and have waterproof devices for use in the shower or bath. However, MobileHelp offers a wider range of wearable device options including a smartwatch, which may appeal to individuals who prefer a more discreet device. Ultimately, the choice between One Call Alert and MobileHelp may come down to personal preference and specific needs.


No long-term contracts, risk-free 30-day trial period, medication reminder option, automatic fall detection, 24-hour emergency support, no cancellation fees (as long as the equipment is returned), advanced payment discounts and competitive pricing.


Not TMA Five Diamond certified, and they do not offer smoke detection or carbon monoxide monitoring options. No activity monitoring and no automatic system testing. Prices subject to change without notice unless you pay for a price lock.

One Call Alert’s costs and fees are straightforward and competitive in the medical alert marketplace. There is no equipment to buy and no activation fees for most of the plans. They also offer free ground shipping on most plans too.

Automatic fall detection can be added to all of the plans too, except the in-home landline, for an additional $11.00 per month. If you have two users in the same household that need a medical alert device, the Mobile Double plan is a great option. You will receive two units and monitoring services for two people for close to the price of one.

Please note that on their website it states that prices are subject to change without notice. We confirmed with them that this also means after you signed-up as a customer. However, they did note that prices have not increased in a long time. If you wanted to protect your monthly payment fee, you can purchase their price lock plan for $6.00 per month to ensure the price will never go up. Some medical alert companies offer price lock guarantees at no charge. Since there are no long-term contracts with One Call Alert, we do not suggest paying for a price lock. You can simply cancel the service if you don’t feel the increase is justified and they won’t honor your current pricing.

*The In-Home Wireless system has a subscription fee of $49.95 but is waived if you are paying annually. If you can afford to pay annually, you can avoid the one-time processing fee of $49.95. One Call Alert had mentioned this to us as well.



Reasonable Service Rates – One Call Alert has competitive rates for both their In-Home and Mobile systems. We suggest comparing other medical alert companies such as Medical Guardian prices. 

Cancel at Any Time Policy – No long-term contracts, you can cancel at any time. If you are not happy with their service, you can cancel and get a refund for unused monthly services when you ship your equipment back to them.

Cellular Option – Most of their subscriptions are cellular based in case you are without traditional land-line phone service, which are becoming increasingly unreliable for alarm monitoring.

Fall Detector Option – (Available with all their systems except In-Home Landline) Since some diabetics can have the tendency to faint and falls are common among seniors, fall detectors can be helpful because the user may be unable to press their medical emergency button.

Mobile GPS Option – For seniors or even young children on the go, this GPS technology may be an important option for you. The GPS can track your loved one’s location and send help exactly where they are when they need it.

Advanced Payment Discounts – One Call Alert offers advanced payment discounts on all their systems.



Monitoring Centers Not TMA Five Diamond – This is an important certification that requires an annual renewal with The Monitoring Association, which shows a commitment to a higher level of service. There are some great monitoring centers that do not have this designation but we prefer monitoring centers that do.

No Carbon Monoxide or Smoke Detection – Both are important features to have in your home and One Call Alert does not have these options.

Prices Subject to Change – One Call Alert states on their website the prices are subject to change at any time. If you are on a fixed income or simply watching your monthly expenses this can be unnerving. You can purchase their price lock plan for $6.00 a month. We prefer companies that have price lock guarantees included at no additional charge.

No Automatic Testing – We prefer that medical alert systems send daily or weekly test signals to the monitoring center to test the communication path between the medical alert system and the monitoring center. One Call Alert suggests the users test the system themselves weekly, which might be difficult for some users to remember.

No Activity Monitoring – Some medical alert companies offer a feature called activity monitoring. It allows you to know if your loved one has been active each day. The user must press a medical alert button once in every 24-hour period or more advanced systems use door contacts, motion sensors and bed sensors to detect no or irregular activity patterns. Activity monitoring allows you peace of mind each day.

How many customers does One Call medical alert have?

Most of the reviews we found on One Call Alert online were positive. Best Company had the overwhelming majority of positive reviews with 75% being 5 stars. Customers have said that One Call Alert’s customer service is caring and helpful. Others are happy with the response times, service and equipment. The few negative reviews we found mentioned the unit not working properly in their home. This could be due to the location of the home and strength of cellular signal. We suggest calling One Call Alert before you start service to ensure you have good cellular coverage in your area.

One Call Alert is not a BBB accredited business but they are 5-star rated with an A+ rating and do not have any negative complaints on file at the time of this review.



One Call Alert’s brand may look familiar as it is sold in various drug stores across the country. One Call Alert has competitive pricing on their medical monitoring packages. However, we are a little wary as they clearly state on their website that pricing may change at any time. But, since you are not locked into a long-term contract (another bonus!) you can cancel at any time. Be sure to promptly return the equipment back to One Call Alert so you are not continually charged.

One Call Alert has two UL certified monitoring call centers located in different parts of the United States, so you can be reasonably assured you will still be monitored if one of the centers is affected by a natural disaster. The monitoring centers however are not TMA Five Diamond Certified, which is a distinction we prefer monitoring centers to have. One Call Alert also does not automatically test their equipment or call to remind you to test it, so we suggest setting a reminder to test your medical alert system at least once a week.

One Call Alert was recently acquired by MobileHelp which is a well-established medical alert monitoring company and OEM equipment manufacturer. We will keep an eye on One Call Alert for any changes that may go along with a major acquisition.

Although our experience with this company had these results, your experience may be different. If you’re interested in this company’s services, contact them to judge for yourself.
