Problem
If you're a T-Mobile customer and unable to access app.salesmessage.com, your carrier's Web Guard security feature may be blocking the site.

Open the T-Life app on your device
Navigate to Account or Profile settings
Select Family Controls
Choose the line experiencing the issue (if you have multiple lines)
Tap Web Guard
Change the setting from High to:
Medium or Low (for some filtering)
No Filtering (to turn Web Guard off completely)
Tap Save changes
Option 2: Using T-Mobile.com
Log in to your account at T-Mobile.com
Click your profile name in the top right corner
Select Profile > Family Controls
Choose the affected line (if you have multiple lines)
Select Web Guard
Change from High to Medium, Low, or No Filtering
Click Save changes
Option 3: Contact T-Mobile Support
If you're unable to change these settings yourself, contact T-Mobile customer service and ask them to adjust or disable Web Guard on your line.
