For security systems, being able to detect security threats is only half the battle. The other half is the ability to signal homeowners about such threats. Alarm signaling was introduced over 100 years ago when a company called American District Telegraph, now better known as ADT, invented a telegraph-based call box that connected neighborhoods to a central office to combat night-time break-ins.
Over the years, communication technology has improved. Telegraph is archaic compared to the technology we have access to today, like the internet and landline. There’s one means of communication, however, that is generally heralded as the best for alarm signaling: cellular signals. That is because cellular signals are wireless, have minimal downtime, and are tamper-proof (no wires to cut!).
In this guide, we’ll help you find the best cellular security system for your home by narrowing down your options to the five we deemed best during our tests.
FYI: Although cellular security systems use cellular signals, they don’t need a mobile hotspot. The cellular chip is built into the base station itself.
Cellular security systems | Typical length of professional monitoring contract |
---|---|
SimpliSafe | 1 month |
ADT | 3 years |
Vivint | 4-5 years |
Cove | 1 month |
Frontpoint | 3 years |

Detailed List of the Best Cellular Security Systems

1. SimpliSafe - Best No-Contract System
SimpliSafe makes good use of simple, affordable, and reliable technology – including cellular communication – to protect homes of all sizes. It even leverages cellular technology to offer uninterrupted protection even through power and internet outages.
There is one catch: To use cellular signals for communication, you’ll need to sign up your system for professional monitoring. Fortunately, SimpliSafe’s pricing for this service is lower than the industry standard. The Standard plan costs $19.99 per month, while the more advanced Fast Protect plan costs $29.99. Both these subscriptions include access to cellular technology.
Standard plan Fast Protect plan $19.99/month $29.99/month Professional monitoring Professional monitoring Cellular backup Cellular backup No home automation Simple home automation No cloud storage Cloud storage for up to 10 cameras No video verification Includes video verification Take note that SimpliSafe uses cellular technology only as backup. By default, the system connects to the internet over Wi-Fi, but when the signal is not available, it switches over to cellular communication.
That is actually an advantage. Internet-connected systems offer more functionality – for example, they can stream video from security cameras, whereas most cellular systems can’t without connecting to Wi-Fi first. With SimpliSafe, you get the best of both worlds: speed and functionality from the internet connection, and reliability from cellular backup.
As for the equipment, everything is standard with SimpliSafe. You get a base station and a keypad, and you get to choose from a variety of sensors. It’s all DIY, but the setup process is as simple as can be. No tools are needed, unless you install SimpliSafe’s video doorbell, which calls for a Phillips screwdriver and perhaps a drill depending on your doorbell setup. All in all, you can get a SimpliSafe system up and running in about 30 minutes.
SimpliSafe Video Doorbell Pro Cellular Coverage, Prices, and DIY Installation
Along with an award-winning monitoring center, what makes SimpliSafe one of the best cellular security system brands? An expansive cellular network, low prices, and easy DIY installation make SimpliSafe a great value for millions of households.
- Expansive Cellular Network – The cellular chips in SimpliSafe security systems can communicate over networks used by Verizon and T-Mobile. This helps make cellular home security available across virtually all the USA. Before buying a SimpliSafe set, you can call the company and verify that cellular security service can be activated at your address.
- Low Prices – SimpliSafe prices are relatively low. That’s true of the equipment and optional cellular monitoring. For equipment, customers get factory-direct deals and can also buy refurbished security systems with long warranties included. The cheapest SimpliSafe starter kit costs about $250, but with SimpliSafe deals, you can often snatch one for less than that.
- Simple DIY Installation – As you’d expect from the name, SimpliSafe is simple to install yourself. Each system arrives with a thumb drive that guides you through tool-free setup. Most equipment is freestanding or can attach to flat surfaces with removable adhesive strips. For instance, you don’t need to plug-in or hardwire SimpliSafe motion sensors; their batteries can last for up to seven years.
Even the monitoring contracts are simple with SimpliSafe. You won’t have to sign a long-term deal with the brand. You only pay as you go, so you can opt in and out of service whenever you want. You can even use SimpliSafe without monthly fees, but again, you’ll lose cellular connectivity if you choose to do so.
To take full advantage of SimpliSafe’s cellular capabilities, we recommend getting a monitoring subscription. The $19.99 Standard plan offers everything you’ll need to self-monitor the system plus professional monitoring from SimpliSafe’s partner monitoring facility. In case of emergencies, the security system will signal both you and the monitoring center, and when needed, an agent will dispatch an emergency response team (police, fire, or medical) to your house.
Expanding on those features, the $29.99 Fast Protect plan adds video verification where the monitoring center will get brief access to camera feeds to confirm alerts, basic home automation and integrations, cloud video storage, and other premium features. Both subscriptions are worth it, based on our tests, but if you have security cameras from SimpliSafe, the Fast Protect plan is the better option.
FYI: With SimpliSafe’s new indoor camera, the Smart Alarm, monitoring agents can now speak through the camera to scare away intruders. This feature is exclusive to the Fast Protect subscription.
SimpliCam Any drawbacks? There are. SimpliSafe falls short when it comes to home automation. While it pairs with Alexa, Google Assistant, and a couple of other smart home brands, it’s not as smart as most other DIY systems of its caliber. SimpliSafe also lacks in terms of security camera options. Currently, there are four: two indoor cameras, a battery-powered outdoor camera, and a hardwired doorbell. If you need more variations, you’re probably better off with a security camera brand like Lorex.
What We Like
- Affordable equipment
- Simple DIY installation
- Affordable monitoring for police/fire/medical emergencies
- Intrusion protection, environmental safety, and home automation
- Monitoring not required
- No credit check
- Works with Amazon Alexa
What We Don’t Like
- Cameras are too simple and don’t have artificial intelligence
- No continuous video recording (Only motion-triggered)
- Does not support Z-Wave
SimpliSafe customers tend to be very satisfied. Customers get a 60-day money-back guarantee, and equipment is under warranty for up to three years.

2. ADT - Best Professionally Installed System
ADT forever changed the home security industry with its introduction of a telegraph-based security network, but it didn’t stop there. As the technology evolved, so did ADT’s home security offering.
The most advanced security system from ADT today is called ADT Control, and it’s one that offers professional monitoring using cellular technology. It also happens to be the best choice for a professionally installed security system.
First, you’ll enjoy generous buyer protections from ADT’s installation service, specifically, a six-month money-back guarantee. With this, if something goes wrong with the system and ADT fails to solve it within the first six months, you’ll get your installation fee and all your monthly fees back.
Second, ADT’s professional installation service is white-glove. ADT sends trained technicians, and once the system is up and running, they’ll hang around to explain how the system works. So you’ll never be on your own.
Each ADT system is customized to the customers’ security needs. The technician can install a basic setup if you so please, or they can install a full-on smart home security system complete with smart home products like smart thermostats, smart locks, and other components. You can also integrate existing smart home products with ADT as long as they are Z-Wave compatible. The ADT mobile app ties everything together, so you can control your home with your fingertips.
ADT Samsung SmartThings Starter Kit With ADT’s professional setup comes advanced features. Some of these features require an internet connection, though. In fact, ADT is like SimpliSafe in this regard – it uses your internet connection as the primary means of communication, but offers cellular technology as backup.
When your internet is working, remote smartphone control is available through the ADT Control app. You can control and monitor your system from any part of the world. You can also use voice control if your home is equipped with smart speakers or displays from either Amazon or Google. You lose those features temporarily when your internet is not working, but thanks to cellular technology, the system can still generate alert signals, with or without an internet connection.
That said, ADT is not perfect. Unlike SimpliSafe that lets customers choose between professional and self-monitoring, ADT requires professional monitoring. Moreover, there’s a long-term contract that needs to be signed. This contract can be anywhere from two years to five years, depending on your equipment payment plan.
Speaking of equipment payment, you can get an ADT system without upfront equipment fees through financing. You can pay as low as $11 per month for a basic security system over the course of three years. This is on top of the monthly monitoring fee.
What We Like
- Same-day professional installation
- Pro monitoring to send police, firefighters, and paramedics
- Works with Alexa and Google Assistant
- Intrusion protection, environmental safety, and home automation
- Hub supports Z-Wave devices
What We Don’t Like
- 720p camera resolution (Crisp, but higher resolution is available)
- Continuous video recording not included (Motion-triggered only)
- Prices not advertised
In any case, ADT is flexible. It caters to every customer’s unique security needs, and with its top-notch professional installation service, we’re giving it the award for the best professionally installed cellular security system.

3. Vivint - Best Smart Security System
Vivint is another option that provides best-in-class professionally installed cellular security systems, but what sets it apart is the unique way it approaches home security: By adding “smarts” to its security system.
Vivint is the best smart security system with cellular monitoring because it uses a variety of modern technology to secure homes, but its specialty is security cameras. It offers top-of-the-line security cameras that can record important events or record continuously for 24/7 playback.
The best smart camera from Vivint is by far the Vivint Outdoor Camera Pro. It’s a sturdy outdoor camera that uses artificial intelligence to detect if there’s someone lurking within or close to your property. If it detects someone, it flashes red lights automatically and will issue an audible warning. The newest version also comes with a microSD card slot, so it can store videos even if your internet is down. It complements Vivint’s cellular monitoring well.
The Vivint home security hub is equipped with a cellular chip to transmit alerts, but it also comes with a Z-Wave chip to connect with a wide variety of smart home products and appliances. With Z-Wave, you can incorporate an endless selection of third-party devices to your system, and then control them using the Vivint Smart Hub. Examples are smart thermostats, dimmers, window shades, garage door controllers, and more.
Vivint security plans are relatively affordable considering their high-quality features. Prices are currently unadvertised at the Vivint site. However, in our experience, the cheapest plan costs just $29.99 per month. For $39.99/month you’ll get remote control over your home with Google Assistant and your smartphone.
Any downsides? Well, there are a couple. First is the cost of equipment, especially if you’re considering security cameras. The Outdoor Camera Pro costs $399, and its indoor and doorbell camera siblings aren’t exactly cheap either.
Vivint cameras Price Outdoor Camera Pro $399 Indoor Camera Pro $199 Doorbell Camera Pro $249 Besides the relatively pricey equipment prices, Vivint customers have only three days to reconsider their purchase — very short compared to the industry standard 30-day return policy. In addition, Vivint uses proprietary equipment. Once your contract is over and you don’t renew, no other alarm company that we know of can monitor your Vivint equipment, so it becomes essentially useless.
What We Like
- Pro installation
- Pro monitoring to send police, firefighters, and paramedics
- Intrusion protection, environmental safety, and home automation
- Works with Google Assistant
- Supports Z-Wave
What We Don’t Like
- Proprietary equipment
- No free trial
All in all, Vivint is the best choice for cellular home security with virtually unlimited home automation. You’ll need to pay each month for service though; unlike the SimpliSafe siren, a Vivint siren won’t sound unless connected to emergency dispatchers. Energy savings and a Vivint-related discount on homeowner’s insurance might help offset the monthly cost.

4. Frontpoint - Best DIY Installed System
Frontpoint combines the best of expert professional alarm monitoring with the pros of a DIY setup. Rapid Response delivers the professional monitoring service, while Frontpoint provides high-quality, 100-percent wireless security equipment.
Installing Frontpoint is easy in our experience. You can set up everything without tools, and if you ever hit a snag during the process, Frontpoint has an incredibly helpful customer desk that can assist you over the phone.
Another great thing about Frontpoint is that, because it’s a DIY system, you can easily take it with you if you ever need to move. Moving the system is free. You’ll just fill out a form, box up the system, and activate it in your new address. Frontpoint will even send out a free Mover’s Kit, which includes fresh adhesive tapes for the sensors.
Pricing for Frontpoint cellular security systems starts at $129 for equipment, plus $49.99 monthly for professional monitoring. Being the only professional monitoring option from Frontpoint, the $49.99 plan includes every feature in Frontpoint’s arsenal: Crash and Smash protection, video monitoring, smartphone remote control, and Google Home and Alexa integrations. The plan also lets you add automation devices such as smart locks and smart thermostats.
Frontpoint finds that customers save up to 20 percent on home energy bills when a smart thermostat is included, so this helps offset the home security expense.
Why choose Frontpoint over SimpliSafe? One advantage is outdoor video surveillance; Frontpoint has weatherproof security cameras. Another advantage is Frontpoint’s Z-Wave radio chip. With Z-Wave and the Frontpoint app, you can easily integrate gadgets from third parties. Adding a component takes about 10 minutes.
Frontpoint Premium Indoor Camera Why choose Frontpoint vs ADT? Frontpoint publishes all its prices, and you can choose a month-to-month service instead of signing a contract. Since you’ll purchase Frontpoint equipment outright, you won’t need a credit check either.
What We Like
- Upfront pricing
- DIY installation
- Pro monitoring to send police, firefighters, and paramedics
- Intrusion protection, environmental safety, and home automation
- Cellular with Wi-Fi backup
- Weatherproof security cameras
- Alexa & Google Assistant
- Supports Z-Wave
- Great customer service
What We Don’t Like
- Cheaper systems are available
- Frontpoint equipment is under warranty for up to three years. Systems carry a 30-day money-back guarantee.

5. Cove - Most Affordable System
Typically, cellular monitoring costs more than landline monitoring. However, with Cove, you don’t have to pay a premium price to enjoy the premium protection that cellular systems provide. When we dug deeper into Cove’s pricing, we were pleased to find their professional monitoring through cellular signals starts at only $17.99 per month. For that price, you’ll get a team of trained monitoring center agents monitoring your system 24/7 for any disturbances, including break-ins, fire, and even medical emergencies (if you spring for all the options, that is).
If you want to get most out of your system, though, you might want to consider upgrading your monitoring plan to Cove Plus. For $27.99 a month, Cove Plus adds in security camera integrations, smartphone control, Alexa and Google Home automations, and a seven-day cloud video storage. Considering that most security companies charge around $50 a month for those features, the extra $10 per month is well worth it.
What We Like
- 24/7 monitoring and cellular backup
- RapidSOS monitoring technology
- Works with Alexa and Google Assistant
- Affordable plans
- DIY Installation
- No contracts
What We Don’t Like
- No self-monitoring option
- Limited equipment options
- Mobile smartphone controls cost $24.99 per month
Cove’s affordability extends to its equipment as well. Keep in mind that Cove’s equipment is entirely wireless, and that all pieces are monitored through the cellular-ready touchscreen panel. With cellular systems, we usually see sensors sold for $30 to $75 a piece, depending on what the sensor does. But with Cove, the most expensive sensor, which is the smoke and carbon monoxide sensor, retails for only $55. And if you purchase your equipment up-front, you’ll get a 50-percent discount. Entry sensors, motion sensors, and glass break sensors all retail for less than $20, including discounts. And one more thing: You’ll get a free indoor camera worth about $100 with any purchase of a security system, not bad at all.
With those prices, you can get a basic Cove system for less than $200 (discounted price). However, if you don’t want to shell out that amount up-front, Cove also offers a flexible payment plan. You will receive up to $450 worth of equipment (retail price) without initial payments in exchange for a 36-month professional monitoring contract and a $10 increase in your monthly payment. Over the course of three years, you will only have paid $360 for the equipment, so we think that’s a fair ask.
Did You Know? Cove offers something called RapidSOS with their cellular monitoring services. RapidSOS allows for Cove’s monitoring center to redirect your alarm signal straight to dispatchers, which should help to improve response time.
FAQ
Have any more questions about cellular security systems? You're not alone. We get asked a lot about cellular systems, so we answered the most common questions here.
-
What are the best cellular security systems?
The best cellular security systems are ADT, Vivint, Cove, Frontpoint, and SimpliSafe. Overall, we liked ADT’s professional installation and monitoring the most, as it provides a high level of security that many DIY systems fail to provide. But really, the best cellular security system depends on what you’re after, so here’s what we liked best about our top picks.
- SimpliSafe: No-contract and affordable monitoring
- ADT: Professional installation and monitoring
- Vivint: Home automation and security cameras
- Frontpoint: DIY installation and great customer service
- Cove: Affordable monitoring and equipment
-
How much do cellular security systems cost?
Cellular security systems cost around $200, typically, depending on the brand, the size of the system, and the technology. In most cases, you can have your security system financed by the alarm company’s financing partner, which will divide the cost into 36 to 60 monthly installments. Aside from the equipment cost, there will be a monthly charge for professional monitoring. The cost also depends on the company offering the service, but among our top picks, Cove and SimpliSafe have the lowest monitoring prices, both starting at $17.99 per month. ADT, Vivint, and Frontpoint monitoring all fall within the $40 to $60 per month price range.
-
Do you need a landline or internet connection to use cellular security systems?
You don’t need a landline or internet connection to use cellular security systems. They use built-in cellular chips to communicate alerts to monitoring centers. However, there are security systems that use two or more communication methods. In such cases, you can connect the security system to your landline or internet and it will use its cellular chip as backup.
-
Can you use cellular security systems without a monthly fee?
You can use cellular security systems without a monthly fee if the alarm company allows self-monitoring for free. With a self-monitored system, the user is responsible for resolving alerts, including calling the police if necessary. However, to make the most of the cellular feature, we recommend getting professional monitoring. Cellular systems communicate with monitoring centers through a cellular chip, which will continue to work even without a landline or internet connection.
