Do it yourself
Cancel SimpliSafe yourself
TLDR: The account owner calls 1-888-783-8441 or uses chat, and may need the Safe Word, before the billing date. There is no termination fee, but a partial month is not refunded.
Cancel by phone
You can reach support. Only the account owner can cancel, and SimpliSafe may ask for the Safe Word.
- 01Call 1-888-783-8441. The monitoring terms also list 1-800-548-9508.
- 02Say you are the account owner and you want to cancel monitoring.
- 03Answer the account-holder check if they ask for the Safe Word.
- 04Ask them to email the confirmation to the account owner's email.
Cancel by chat
You would rather type than call. The account owner still has to be the one asking.
- 01Open SimpliSafe chat from the cancel article.
- 02Say you want to cancel the monitoring plan and that you are the account owner.
- 03Complete the Safe Word check if they ask.
- 04Save the chat and wait for the confirmation email.
Start a cancel request online
You live in a state where SimpliSafe shows online cancellation. It is only available during standard hours of operation.
- 01Sign in at simplisafe.com as the account owner.
- 02Click the Account icon on the home screen, then Security Dashboard, then Manage Account.
- 03Start the cancellation request at the bottom of the screen.
SimpliSafe does not list the clock times for those standard hours on the cancel article.
Start a cancel request in the app
The app shows Initiate Cancellation. The terms say that can create a request and a call back.
- 01Open the SimpliSafe app as the account owner.
- 02Use Initiate Cancellation if it is there.
- 03Answer the call back. They use it to confirm the cancellation.
Cancel by mail
You want the monitoring terms' written notice. It is effective when SimpliSafe receives it and confirms it.
- 01Write that you want monitoring terminated, and include the account owner's name and the monitored address.
- 02Mail it by regular mail, postage prepaid, or by overnight delivery, to SimpliSafe, Inc., 100 Summer Street, 3rd Floor, Boston, MA 02110.
- 03Keep proof of delivery. SimpliSafe may call and ask the account-holder security questions before they confirm it.
How to know it worked
- The cancel article says you get a confirmation email at the account owner's email once the cancellation is processed.
- A written notice is effective when SimpliSafe receives it and confirms it. They may call to check that the account holder made the request.
- Cancel before the billing date if you do not want a charge for the coming month. The terms say there is no termination fee.
Watch out for
- Only the account owner can cancel. A delegate on the account is not enough. They may require the Safe Word, or the standard account-holder security questions on a letter.
- An app request can turn into a phone call to the number you gave. If you miss that call, the terms do not treat the request as confirmed.
- Monitoring bills monthly in advance. A subscription ended before the billing date does not create the coming month's charge. A partial calendar month is not refunded. Unearned charges for a full calendar month after termination are refunded.
- Returning the hardware is separate. The 60-day satisfaction return is for systems bought from SimpliSafe or a SimpliSafe representative, counted from the delivery date. Retail purchases go back to that store. Cancelling monitoring does not send the hardware back.
SimpliSafe refunds
- The terms say there are no termination fees.
- They refund unearned service charges for any full calendar month after termination. They do not refund a partial calendar month.
- Unused prepaid months are refunded to the card on file, or to you, at SimpliSafe's discretion.
- A hardware return inside 60 days of delivery, for a direct purchase, is a separate refund. Support makes the label. After the warehouse receives it, there is a 5-7 business day processing time before the refund goes to the original payment method.
