How Can I Block Text Messages?

On iPhone or Android, block the sender in Messages, turn on spam protection, and report junk texts to your carrier at 7726.

Spam texts waste time and carry risk. iOS and Android include tools to block senders, filter unknown contacts, and flag junk. This guide shows clear steps and the 7726 reporting route.

Blocking Unwanted Text Messages On Android And iPhone

Quick map: you can stop repeat senders, push unknowns into a quiet folder, and alert your carrier so fewer copies reach you and others. The table below shows the common routes.

Method	Where It Works	What It Does
Block Sender In Messages	iPhone, Android	Stops texts, calls, and FaceTime/RCS from that number.
Filter/Screen Unknown Senders	iPhone	Moves unknowns to a separate list and silences alerts.
Spam Protection In Google Messages	Android	Detects junk, warns you, and lets you block/report fast.
Report To 7726 (SPAM)	AT&T, Verizon, T-Mobile, many global carriers	Forwards samples to the network for investigation and blocking.
Report To Authorities	US/CA/UK and others	Send scams to the FTC/FCC, Canadian Anti-Fraud Centre, or Ofcom guidance.

Each option has a place. Blocking stops one sender. Filtering trims noise. Reporting helps choke a campaign.

How Can I Block Text Messages? On iPhone Step-By-Step

Apple documents three core moves: block the sender, filter unknown senders, and report junk. Links to Apple’s pages sit at the end of this guide.

Block a sender in Messages — Open the thread, tap the name or number at the top, tap Info, then tap Block this Caller. New texts, calls, and FaceTime from that contact stop.
Filter unknown senders — Go to Settings > Messages, turn on Filter Unknown Senders. Unknowns move to the Filters > Unknown Senders list so alerts stay quiet.
Use Report Junk on unfamiliar iMessages — When a new iMessage shows a Report Junk link, tap it to send the content and sender info to Apple and delete the thread.
Screen Unknown Senders in newer iOS versions — In recent releases, you can open Messages, tap Filters, then Manage Filtering to turn on Screen Unknown Senders. Unknowns route away from your main list.
Review or unblock later — Go to Settings > Messages > Blocked Contacts to review the list. Remove entries if you blocked someone by mistake.

Heads-up: carrier texts like codes or delivery notices can land under Unknown Senders when filtering is active. Check that list if you are expecting a code.

How Can I Block Text Messages? On Android With Google Messages

Google Messages includes quick blocking and strong spam protection. Most Android phones ship with this app, and you can install it from Play if yours doesn’t have it.

Block right from the list — Open Google Messages. Touch and hold the conversation, tap Block, then confirm. You can also open a thread, tap the three-dot menu, and choose Details > Block & report spam.
Turn on Spam Protection — In Google Messages, tap your profile photo > Messages settings > Spam protection. Turn it on so suspicious texts get flagged and moved.
Report spam when prompted — After blocking, leave the report box checked to share a sample. This helps the system catch similar waves.
Check the Spam & blocked folder — If a text goes missing, open the side menu and tap Spam & blocked. Move legit threads back to the inbox.

Carrier Tools And The 7726 Number

Major carriers ask you to forward junk texts to 7726 (which spells SPAM). This free short code sends samples to the network’s spam filters. Many countries support the same code.

AT&T — Forward the text to 7726. AT&T’s page spells this out and encourages reporting to the FTC as well.
Verizon — Forward the text to 7726 and follow the reply prompts to share the sender’s number.
T-Mobile — Forward to 7726 on any device. T-Mobile also lists common opt-out words like STOP for legitimate marketing lists.
UK networks — The same 7726 number works across major UK providers under Ofcom guidance.
Canada — Forward to 7726 and report scams to the Canadian Anti-Fraud Centre.

Why 7726 matters: your sample helps the carrier shut down a campaign at the source. That can cut messages to everyone on the network, not just you.

Safer Habits That Cut Junk Texts

Blocking and reporting are the main moves. A few habits keep you even safer.

Never tap links in a random text — Open the brand’s app or type the site address yourself. Many scams spoof delivery firms and banks.
Avoid replying, except STOP for known lists — If you opted into messages from a store, reply STOP to leave. For unknown senders, do not reply at all.
Hide previews on the lock screen — In iPhone Settings > Notifications > Messages, set previews to When Unlocked. On Android, open system notification settings and reduce previews for sensitive content.
Watch app permissions — Third-party SMS blockers exist, but grant SMS permissions only to apps you trust and that you plan to keep.

Fixes When Blocking Doesn’t Seem To Work

Spammers rotate numbers, which can slip around a single block. Here are moves that hold up over time.

Block and report every new copy — Each sample trains device and carrier filters. The more samples a network sees, the faster a run gets cut down.
Enable every filter you have — Keep iPhone’s Unknown Senders filter on. Keep Google’s Spam protection on. Combine these with 7726 reporting.
Silence alerts from unknowns during a surge — On iPhone, the Unknown Senders filter mutes alerts. On Android, snooze notifications for the worst threads after you block them.
Use group-text controls — On iPhone, open the thread and tap the top name to leave or mute a group. On Android, open the three-dot menu and mute a group so it stops buzzing.
Change your number as a last resort — If a leak triggers constant waves, ask your carrier about a number change and account-level filters.

If you came here typing “how can i block text messages?”, the steps above will solve most cases. Use device tools first, keep spam protection on, and send samples to 7726 when a wave starts.

Choosing The Right Mix For Your Situation

Different problems call for different tools. Pick the path that matches what you see on your phone.

If One Number Keeps Bugging You

Direct block: use the built-in Block feature on iPhone or Android. That cuts off texts from that number across calls and video. Add one more step and report a sample so the filters learn from it.

If You Get Waves From New Numbers

Filter and report: turn on Unknown Senders on iPhone and Spam protection on Android. Then forward a few copies to 7726. That combo reduces noise while the carrier hunts the source.

If The Messages Look Like Real Brands

Check inside the app: open the brand’s app or log in through your browser. Many phishing texts spoof deliveries, banks, and tax agencies. Do not tap a link in the text. Use the app to confirm.

If You Opted Into Store Alerts

Use STOP: reply with a standard opt-out word like STOP or UNSUBSCRIBE. That ends legit campaigns that follow the rules. If messages continue, report a sample to 7726 and block the thread.

If Group Chats Go Off The Rails

Mute or leave: silence a chat so your phone stays quiet, or leave the group when the app allows it. You can still block the organizer if they add you back.

How Blocking Interacts With SMS, MMS, RCS, And iMessage

Text tech stacks vary, but the basics stay the same. A block in Apple’s Messages stops iMessage and SMS from that contact. A block in Google Messages covers SMS, MMS, and RCS. Spam protection works across formats. Block where you read texts and let filters handle the rest.

Preventing Your Number From Getting On More Lists

Nothing stops every blast, yet small habits cut exposure.

Share your number sparingly — Skip public posts with your phone number. Use an alternate line for sign-ups that tend to send promos.
Use two-factor apps over SMS when available — App-based codes mean fewer SMS messages for attackers to copy or spoof.
Don’t reuse one-time codes anywhere — Treat codes like keys. If a site prompts you for a code you just received that you did not request, close the tab.

RCS or iMessage quirks: if texts still arrive from a blocked contact, confirm the block on the phone number and the linked Apple ID or RCS profile. On iPhone, open the thread card, tap Info, and check Block this Caller. On Android, open the profile panel and confirm Block & report spam was applied to that thread. Ask friends to remove you from group chats that include the sender, since group replies can route around a single block.

Update the Messages app and your phone’s system software today, then test with a friend.

One more use of the exact phrase for readers who searched “how can i block text messages?”: block the sender, filter unknowns, keep spam protection on, and forward samples to 7726.
