Message blocking stops texts from reaching you, and how you disable it depends on whether your phone, your carrier, or a third-party app is doing the blocking
Message blocking can happen at three different places: on your phone itself, through your carrier's network, or through an app you installed. The first step is figuring out which one is active. If you're not receiving texts from a specific person or number, check your phone's built-in filters first — most phones have a "blocked contacts" or "spam protection" setting that silently stops messages. If that's not it, contact your carrier to ask whether they're filtering the messages on their end. If neither of those is the problem, a third-party app like Google Messages or a security app may be blocking the sender.
The good news is that disabling message blocking is straightforward once you know where it's happening. Most of the time, the block is on your phone itself, and you can remove it in under a minute. If your carrier is blocking messages, a phone call to their customer service line will get it sorted. The process is the same whether you use iPhone or Android — the menu names just differ slightly.
Key Takeaways
- Your phone's native messaging app usually has a blocked contacts list where you can unblock specific numbers or turn off spam filtering.
- Your carrier — Verizon, AT&T, T-Mobile, or another provider — may be blocking messages at the network level, and you can call them to check or disable this.
- Third-party messaging apps and security software can also block incoming texts, and you may need to adjust their settings or uninstall them.
- Message blocking is different from Do Not Disturb or silent mode, which mute notifications but don't prevent the message from arriving.
Check your phone's blocked contacts list first
Most phones have a built-in way to block specific numbers or contacts. On an iPhone, open Settings, tap Messages, scroll down to "Blocked Contacts," and you'll see a list of any numbers you've blocked. Tap "Edit" in the top left, then tap the red minus sign next to any number you want to unblock. On Android, the steps vary by manufacturer, but generally you open your default messaging app (like Google Messages or Samsung Messages), tap the three-line menu, go to Settings, then Blocked Numbers or Blocked Contacts, and remove the number from the list.
If you don't see the number in your blocked list but still aren't receiving messages, check whether spam filtering is turned on. On iPhone, this is in Settings > Messages > Filter Unknown Senders — toggle it off if you want to receive texts from numbers not in your contacts. On Android with Google Messages, tap the three-line menu, go to Settings > Spam Protection, and turn off "Enable Spam Protection" if it's on. Be aware that turning off spam protection means you may receive unwanted texts, but it will allow legitimate messages through.
Ask your carrier whether they're blocking messages
Your phone company can block messages at the network level before they ever reach your phone. This is usually done through a service like Verizon Call Filter, AT&T Call Protect, or T-Mobile Scam Shield. Call your carrier's customer service number (it's on your bill or their website) and ask whether message filtering is active on your account. Tell them the specific number or type of message you're not receiving, and ask them to check their logs to see whether the message was blocked on their network.
If your carrier is blocking the messages, ask them to turn off the filter or to whitelist the specific number so messages from that sender get through. Some carriers let you manage this yourself through their app or website — Verizon customers can use the Verizon Call Filter app, for example — but calling customer service is usually faster if you're not sure how to navigate their system. The whole call typically takes five to ten minutes.
Disable third-party messaging apps or security software
If you've installed a third-party messaging app like Google Messages, Samsung Messages, or another alternative, that app may have its own blocking settings. Open the app, go to Settings, and look for a "Blocked Contacts," "Spam," or "Filtering" section. Remove any numbers from the blocked list, or turn off spam filtering if it's enabled. Some security apps like Norton, McAfee, or Kaspersky also include message filtering — check their settings under "Privacy," "Blocking," or "Message Protection" and disable any filters that might be stopping legitimate texts.
If you're using a custom ROM or a phone with heavy manufacturer customization, there may be additional filtering layers. For example, some Samsung phones have a "Spam Protection" setting in the native Messages app that's separate from the blocked contacts list. Check your phone's Settings app under "Apps," "Messages," or "Notifications" to see whether there are any filtering options you haven't found yet. If you recently installed a new security app or messaging app and the blocking started around the same time, that app is likely the culprit.
Distinguish message blocking from Do Not Disturb and silent mode
Message blocking is not the same as Do Not Disturb or silent mode. Do Not Disturb and silent mode stop notifications from appearing on your screen and mute sounds, but the messages still arrive on your phone — you just won't see or hear them until you turn off those modes. If you're not seeing messages at all, even after checking Do Not Disturb, the problem is actual blocking, not just muted notifications.
To check whether Do Not Disturb is on, look at the top of your screen on iPhone (you'll see a moon icon) or swipe down from the top on Android to see your quick settings. Turn it off if it's active. This won't solve a blocking problem, but it's worth ruling out first because it's the most common reason people think they're not receiving messages when they actually are. You can also check your Messages app directly — if messages are arriving but you're not getting notifications, Do Not Disturb is the issue.
What to do if you still aren't receiving messages
If you've checked your phone's blocked list, turned off spam filtering, called your carrier, and disabled third-party apps and you're still not receiving messages, the problem may be on the sender's end. Ask the person trying to reach you to check whether they have you blocked, or whether their carrier is blocking outgoing messages to your number. You can also try asking them to send a message from a different phone or number to see whether the problem is specific to their device or account.
Another possibility is that your phone number was previously associated with spam or fraud, and your carrier is still filtering messages to it. Call your carrier and explain that you're not receiving legitimate messages, and ask whether your number has a flag or filter on it that they can remove. This is less common but does happen, especially if you recently got a new phone number. Your carrier can usually clear this flag within a business day.
Frequently Asked Questions
Can I block messages from a specific number without blocking all messages?
Yes. On iPhone, open the message thread from that number, tap the contact name at the top, scroll down, and tap "Block this Caller." On Android, open the message, tap the three-dot menu, and select "Block" or "Block Number." The person can still send you messages, but you won't see them — they'll go to a blocked folder or be deleted depending on your phone's settings.
If I unblock someone, will I see their old messages?
No. Unblocking a contact only stops new messages from being filtered going forward. Messages that arrived while they were blocked are usually deleted. If you need to see old conversations, ask the person to resend the messages after you unblock them.
Does turning off spam protection mean I'll get more spam texts?
Yes, probably. Spam protection filters out messages from numbers that are flagged as spam or phishing. Turning it off means those messages will reach you. You can always turn it back on if you start receiving too many unwanted texts, or you can block individual numbers as they come in.
Why would my carrier block a message I'm trying to receive?
Carriers block messages they identify as spam, phishing, or fraud. Sometimes legitimate messages get caught in these filters by mistake — for example, messages from banks or services that use automated systems. If this happens, contact your carrier and ask them to whitelist the sender's number.
What if the person I'm trying to reach says they sent a message but I never got it?
Ask them to check whether they have you blocked, or whether their phone is set to block outgoing messages. Have them try sending from a different device or number. If the message goes through from a different number, the problem is their phone or account, not yours. If it doesn't go through from any device, your carrier may be blocking their messages — call them to investigate.
