Overview
If your property's notifications number has been verified and a technician is still not receiving emergency text messages, there are a few common settings to check. Most issues are caused by notification preferences, incorrect contact details, or device-level call screening settings, phone carrier filtering, blocked numbers, or subscription status with the property’s dedicated, SMS number.
This guide walks through what to verify so emergency alerts are delivered on time.
How to Troubleshoot (complete in order)
1. Check Account and Notification Settings
Make sure the technician is opted in to receive alerts and has a valid phone number on their profile.
In Call Complete
Go to Profiles
Open the technician’s user profile
Confirm a phone number is added correctly
Turn on Phone and Text Notifications
Enable Emergency Maintenance Notifications
In Call Management
Go to Settings
Open the technician’s user profile
Select the Notifications tab
Opt in to receive alerts
2. Check the technician’s phone and device settings
On the technician’s device:
Make sure messages from unknown numbers are allowed
Check SMS and notification settings
Review spam or filtered message folders
Confirm the alert phone number is not blocked
Save the property’s alert number as a contact
Check with the mobile carrier for restrictions on automated messages
3. Re-subscribe to SMS notifications (important)
If the emergency call was received but no text came through:
Open the Messages app
Text SUBSCRIBE to the property’s dedicated SMS number
What to expect:
If you receive a confirmation message, you’re successfully subscribed
If you don’t receive a confirmation, reply SUBSCRIBE a second time
If there is still no confirmation message:
Take a screenshot showing both SUBSCRIBE attempts

Important iPhone setting for emergency calls (iOS 18+)
What this is
On iOS 18 and newer, Apple includes call screening options at:
Settings → Phone → Screen Unknown Callers
One option, Ask Reason for Calling, can intercept calls from unsaved numbers before the phone rings.
Why this affects emergency alerts
Call Complete relies on immediate call delivery to trigger:
Emergency alerts
After-hours call routing
SMS notifications tied to incoming calls
If Ask Reason for Calling is enabled:
Calls may be delayed
Emergency calls may not ring right away
SMS alerts may not trigger
Calls may appear missed or screened
This can look like a system issue, but it’s caused by the phone’s call screening setting.
Required setting for emergency call recipients
For anyone responsible for emergency or after-hours calls:
Recommended setting:
Screen Unknown Callers → Never
This ensures:
Calls ring immediately
Emergency workflows aren’t interrupted
Alerts and notifications work as expected
Note: Call screening behavior is controlled by Apple and cannot be overridden by the app or messaging provider.
⚠️ Check for call-blocking or call-filtering apps
Some devices use call-blocking or call-filtering apps that can prevent emergency calls or SMS alerts from being delivered.
Call Protect is one common example. It is a free app available to postpaid wireless customers on iOS and Android and may be enabled by default. While often associated with carriers, it is an end-user feature that can:
Automatically block known fraudulent calls
Flag or silence suspected spam calls
Temporarily block numbers reported by the user
If emergency calls or texts are not being received, we recommend:
Confirming whether Call Protect or a similar app is enabled on the affected device or phone number
Contacting the mobile provider to verify whether calls are being filtered or blocked at the device or carrier level
Additionally, we recommend registering the affected phone numbers with the Free Caller Registry:
👉 https://freecallerregistry.com/fcr/
This registry shares call identity data with major carriers. While registration does not guarantee immediate resolution, it can help reduce improper call blocking over time.
Note: If the user has already confirmed that no call-blocking apps are enabled and the carrier is not blocking calls, continue with the troubleshooting steps below.
