You cannot block a specific phone number directly inside the T-Mobile app. The T-Mobile app only offers Scam Block for suspected spam calls, and for blocking a specific number, T-Mobile directs you to your device’s built-in call blocking settings.
Can you block a number on the T-Mobile app?
No, the T-Mobile app does not include a feature to block an individual phone number. The app provides Scam Block, which automatically blocks calls identified as likely scams, but it cannot block a specific number you choose. T-Mobile’s current help page says to use the app to turn on Scam Block, and for blocking a specific number it points you to the Devices page for your phone’s manufacturer blocking steps.
How to turn on Scam Block in the T-Mobile app
Scam Block stops calls that T-Mobile’s network identifies as likely scams. This is the only call-blocking feature available inside the app itself. To turn it on, follow these steps:
- Download the free Scam Shield app from your device’s app store, or open the T-Life app if you already have it.
- Log in to your T-Mobile account using your T-Mobile.com credentials or your T-Life login.
- Find the Scam Block toggle in the app’s main menu or settings section.
- Turn on Scam Block to stop scam likely calls T-Mobile has identified.
This feature is available to T-Mobile postpaid and Metro by T-Mobile customers. Once enabled, it will block calls flagged as spam without requiring you to add numbers manually.
Where to find steps for blocking a specific number
Since the T-Mobile app cannot block a specific number, you must use your phone’s built-in call blocking feature. T-Mobile’s help page instructs you to:
- Visit T-Mobile’s Devices page on their website.
- Select your exact phone model from the list.
- Follow the manufacturer’s instructions for blocking calls and numbers, which are specific to iPhone or Android. You can add numbers to the block list by importing contacts from your address book or call log.
These steps vary by device. For example, iPhones let you block a number from the recent calls list or Contacts app, while Android phones typically offer a block option in the Phone app’s call log or settings. T-Mobile does not provide app menu steps for this because the blocking is handled by your phone’s operating system, not the carrier app.
Alternatives if your phone lacks blocking options
If your phone does not offer built-in call blocking, T-Mobile provides a paid alternative called Family Allowances. This feature lets you manage calls and texts for lines on your account, including blocking specific numbers. Additionally, if you use a DIGITS line, you must contact T-Mobile directly to enable Scam Block, as some features vary by line type.
Frequently Asked Questions
Can I block a number from calling and texting me in the T-Mobile app?
No. The T-Mobile app only controls Scam Block for suspected spam calls. Blocking a specific number from both calls and texts must be done through your device’s settings or Contacts app.
How do I unblock a number I previously blocked on my phone?
To unblock a number, go to your phone’s call blocking or blocked contacts list. On iPhone, this is in Settings > Phone > Blocked Contacts. On Android, open the Phone app, tap the three-dot menu, and select Settings > Blocked numbers. Remove the number from that list.
Does T-Mobile offer a way to block numbers without using my phone’s settings?
For specific numbers, no. T-Mobile’s only call-blocking feature in the app is Scam Block, which blocks scam likely calls T-Mobile identifies. For individual numbers, you must use your device’s manufacturer blocking steps.
