App Error: You Have Exceeded The Maximum Number of Phone Messages Per Hour

In some rare instances, you may receive the error “You have exceeded the maximum number of phone messages per hour” when attempting to log in to the SimpliSafe® App. This error indicates that your device has blocked the Multi-Factor Authentication (MFA) number for SimpliSafe® or that your carrier has short codes disabled*.

The MFA number that SimpliSafe® uses is 857-957-6630

To unblock the MFA number on iOS (iPhone), use these steps:

1. Open up the phone app on your device and call 857-957-6630

2. You should receive a message stating “Sorry, the number you dialed is not in service”

3. Go to recents on your phone app

4. Select All from the top left corner

5. Locate 857-957-6630 and select the blue “i” (information) icon on the right

6. Scroll to the bottom of the page and select “Unblock this caller”

To unblock the MFA number on Android, use these steps:

1. Open up the phone app on your device and call 857-957-6630

2. You should receive a message stating “Sorry, the number you dialed is not in service”

3. Go to recents on your phone app

4. Locate 857-957-6630 and select the “i” (information) icon on the right

5. Scroll to the bottom of the page and unblock the contact

After the number has been unblocked, try logging in again. If you continue to receive the error “You have exceeded the maximum number of phone messages per hour” please wait one hour before trying again. There is a limit of 10 MFA texts per hour. If you exhaust all 10 attempts, you must wait at least 1 hour from the initial login to try logging in again. However, if that login fails, you will need to wait another hour for one of the login attempts to clear. It will take a maximum of 10 hours for all of the failed login attempts to clear, at the rate of one falling off per hour.

Note: MFA codes are only avaialble through text (SMS) for UK customers.
