If your Alarm.com or Total Connect 2.0 alerts show up as text messages, they may rely on an old email-to-text trick that carriers are now shutting down. You might not notice when it quietly stops working. AT&T and T-Mobile have already cut theirs off for good, and Verizon's shutdown looms.

This isn't a rumor or a future warning. For two of the three major carriers, it has already happened. If you set up your alarm notifications years ago and haven't touched them since, this is worth five minutes of your time today.

What Is Email-to-Text, and Why Did People Use It?

Before Alarm.com and Total Connect 2.0 offered push notifications through their own apps, there was a popular workaround for getting alarm alerts as text messages. Every major carrier had (or still has) a special email address format that turns an email into a text. Send an email to a phone number followed by the carrier's domain, like 5551234567@vtext.com for Verizon or 5551234567@tmomail.net for T-Mobile, and it lands on that phone as an SMS.

Alarm.com and Total Connect 2.0 both let you add an email address as a notification destination. Plenty of customers used that feature with a carrier's email-to-text address instead of a real email inbox, which let them get alarm alerts as texts without needing a smartphone app at all. It worked well for a long time, especially before push notifications existed as an option.

Carriers Are Shutting the Gateway Down

Email-to-text was never officially part of how Alarm.com or Total Connect 2.0 were designed to send alerts. It only worked because carriers allowed it, and carriers are walking that back.

T-Mobile hasn't published anything official about this, which is why we can't point you to a source the way we can for AT&T and Verizon. Based on reports from users online, the shutdown appears to have happened quietly around the same time as AT&T's, on June 17, 2025.

Why This Is Risky If You're Still Using It

The dangerous part isn't that this feature is going away. It's how it goes away. There's no error message on your alarm system and no warning in the app. The text messages just stop arriving, and unless you're specifically testing your system, you may not find out until you need an alert and it never comes.

For an alarm or fire notification, that gap is exactly the wrong place to lose reliability.

Alarm.com Already Saw This Coming

This shift didn't come out of nowhere. Back in March 2024, Alarm.com rolled out a push notification migration tool aimed at customers on carriers with degraded SMS and MMS delivery, T-Mobile, Sprint, and Rogers in Canada among them. At the time, Alarm.com called the migration voluntary, but noted it "may become mandatory" if carrier changes made it necessary. That's more or less what's happening now.

Switch to Push Notifications Today

Push notifications don't depend on carrier text messaging at all. They travel over your phone's internet connection, cellular data or WiFi, straight to the Alarm.com app or the Total Connect 2.0 app. That also means they can do things a text message can't, like let you act directly on an alert or come through even when your phone is set to Do Not Disturb.

Open your notification settings in the Alarm.com app or the Total Connect 2.0 app and make sure push notifications are turned on for the alerts you care about, arming and disarming, sensor activity, and alarms especially. If you're not sure how your account is currently set up, or you want help moving away from an old email-to-text address, contact our support team and we'll walk through it with you.

Not an Alarm Grid customer yet? Take a look at our monitoring plans. No contracts, no activation fees, and no cancellation fees, just straightforward alarm monitoring.

No need to consult your Magic 8 Ball on this one, we'll be glad to help you answer it! In short: if your alarm system or communicator runs on Alarm.com or AlarmNet, it likely isn't locked to one company. It just needs to be properly released from the original provider's monitoring account.

Homeowners may assume their alarm system belongs to whoever installed it. If a monitoring company set up the equipment, doesn't that company own it forever? Not necessarily. Alarm.com and AlarmNet (the network behind Resideo's Total Connect service) aren't owned by any single monitoring company. So once your system is released from the current account, any other monitoring company affiliated with the communication platform can pick up the monitoring.

What Makes a System "Non-Proprietary"

Most modern security panels talk to a monitoring company through one of a few shared networks. Two of the most common are Alarm.com and AlarmNet. Neither network is owned by a single monitoring company. Dozens of providers, including Alarm Grid, offer monitoring on panels that use them.

That's different from a proprietary system, where the panel only works with one company's software and can't be reprogrammed to work with anyone else. If your panel uses Alarm.com or AlarmNet, there's a good chance it was built to be flexible from day one, even if the company that installed it isn't.

The Exception: Some Equipment on These Networks Is Still Proprietary

Running on Alarm.com or AlarmNet doesn't automatically mean a system is open to any provider. Some companies build their own locked-down equipment on top of these shared networks. This shows up most with ADT, but Vivint and a few other large providers do it too. The hardware often comes from the same manufacturers everyone else uses, but it ships with a company-specific firmware, a modified part number, or an account binding that ties it to one provider alone.

If you own one of these proprietary devices, you'll generally need to replace it before you can switch monitoring companies, even though under the hood it communicates over one of these shared networks. One thing to look for is a company-specific tag added to an otherwise standard part number, like the "-ADT" or "-BRK" endings in the table below. If you're not sure whether your panel is proprietary, check the exact model number printed on the panel or the communicator and ask a prospective new monitoring company to confirm before you commit to switching.

A note on the list below: these model numbers came from online research, not from the manufacturers or monitoring companies themselves. Because this kind of information is treated as proprietary, we have limited ability to confirm it's fully accurate or current. If your equipment matches, or looks close to, one of these models, confirm its status with a prospective monitoring company before assuming anything either way.

What About Ring and SimpliSafe?

You'll also see Ring and SimpliSafe promoted heavily any time you search for a security system, especially as a DIY installer. These aren't professional-grade systems, meaning professional installers likely aren't installing them, and they're a different kind of proprietary than the ADT and Vivint equipment described above. Neither Ring nor SimpliSafe run on Alarm.com or AlarmNet. Instead, they're built on their own closed platforms from the ground up, so there's no shared network to release your equipment into.

If you want ongoing monitoring on a Ring or SimpliSafe system, you're locked into their monitoring plans (Ring Protect or SimpliSafe's monitoring service) for as long as you own that hardware. Switching providers on this kind of system generally means replacing the equipment in its entirety, not simply requesting a release of your system.

The Real Rule: One Company at a Time

Here's the part that trips people up. A non-proprietary system can only be monitored by one company at a time. While your equipment is active on an account with your current provider, no other company can take over monitoring for it, even though the technology may allow it. The system has to be released from the original account first.

This is where some customers get stuck. Say you've decided to cancel, your equipment is paid off, and you're no longer under contract with the installing company. At your request, your alarm company should release the equipment so you can take it to a new provider.

Some companies make this difficult. They may tell you your system or its communicator can't be used anywhere else. In most cases involving non-proprietary Alarm.com or AlarmNet equipment, like the kind described as non-proprietary above, that isn't true. The system can be used elsewhere. It just needs to be released first.

In most circumstances, AlarmNet and Alarm.com will not facilitate the release of a system. Think of your old monitoring company and your prospective new one as warring nations. In this analogy, AlarmNet and Alarm.com are Switzerland. They don't take sides. One exception to this rule is when the original monitoring company is defunct and your equipment is stuck tied to an account nobody is managing anymore.

How Alarm Grid Handles It

Alarm Grid was built around the idea that customers should never feel trapped. We don't use contracts. We don't charge activation fees. We don't charge cancellation fees.

If you ever decide to cancel your account with us, we'll ask why. We'll see if there's anything we can do to fix the problem or find you a better plan. But once it's clear you want to move on, we process the cancellation and release your equipment. That frees it up to be picked up by any other monitoring company that supports your system's platform, whether that's Alarm.com or AlarmNet.

Know Before You Buy (or Switch)

If you're shopping for alarm monitoring, or thinking about switching providers, ask these questions before you sign up with anyone. First, does the equipment run on Alarm.com or AlarmNet? Second, is any of the equipment proprietary? Third, does the company require a contract, and do they charge fees for cancellation or early termination? The answers will tell you how much freedom you'll actually have down the road.

Ready to make the switch, or start fresh with an easy, no-contract monitoring plan? You can email us with questions at support@alarmgrid.com or call us at 888-818-7728. We're here Monday - Friday from 9:00 AM - 8:00 PM Eastern Time, and happy to help you figure out whether your current system can be moved to a new provider.
