The fastest fix is to turn on the phone’s built-in spam filter first, then add Truecaller or Hiya only if junk texts keep slipping through. Built-in tools on iPhone and Android are free, safer for privacy, and good enough for many people. That matters because text scams are not just annoying; the FTC said people reported $330 million in losses from text message scams in 2022 [source: FTC].
TLDR: iPhone users should enable Filter Unknown Senders, while Android users should turn on Spam protection in Google Messages. For example, a person getting 20 junk texts a week may see most obvious scam messages sent to a separate spam folder or flagged before opening. Truecaller is stronger for caller ID and community spam reports, while Hiya feels simpler and lighter. The catch is that third-party apps may ask for more access than some users want to give.
How iPhone Blocks Text Messages
Apple gives iPhone owners two practical tools. The first is sender blocking. The second is filtering unknown senders.
- Block one sender: Open the message, tap the name or number, tap Info, then choose Block this Caller.
- Filter unknown senders: Go to Settings, tap Messages, then turn on Filter Unknown Senders.
- Report junk: In some regions, iMessage spam can be reported with the Report Junk option.
This works well for random numbers and one-off spam. It keeps unknown senders away from the main inbox. Still, it does not always stop the notification noise. It also may hide real messages from a new doctor, bank, delivery driver, or school office. That part can be irritating, because checking the filtered list adds a few extra seconds every time.
Apple also allows SMS filtering apps. These apps can sort messages into categories, such as transactions, promotions, and junk. The user can manage this under iPhone message settings. Apple explains its message filtering controls in its support pages [source: Apple].
How Android Blocks Text Messages
Most Android users rely on Google Messages. It includes spam protection that checks suspicious SMS and RCS messages. When it works, it flags risky texts before the user taps a link. That is the whole point.
- Block one sender: Open the chat, tap the three-dot menu, then choose Block and report spam.
- Turn on spam protection: Open Google Messages, tap the profile icon, choose Messages settings, then tap Spam protection.
- Check spam folder: Open the menu in Messages and review Spam & blocked.
Samsung phones may use Samsung Messages instead. The steps are similar, but the menus may look different. Many carriers also offer spam blocking. Verizon, AT&T, and T-Mobile all have tools for scam calls and texts, though the best features may sit behind paid plans. Honestly, it feels silly that basic protection is sometimes treated like an upgrade.
Built-In Filters vs Truecaller
Truecaller is best known for caller ID, but it also helps with spam detection. Its strength is its large community database. If many users mark a number as spam, others may receive a warning earlier.
For people who get spam calls and spam texts, Truecaller can feel more complete than the built-in tools. It can identify unknown numbers, block known offenders, and show labels for suspected scams. On Android, it tends to feel more powerful because the system gives apps more room to handle calls and texts. On iPhone, Apple’s limits make the experience more restricted.
The downside is privacy. Truecaller may request access to contacts, caller ID permissions, and messaging features, depending on the device and region. Some users will be fine with that. Others will not. For a person who only gets two spam texts per month, it may be overkill.
Built-In Filters vs Hiya
Hiya is a cleaner option for people who want simpler spam protection. It focuses on caller ID, scam alerts, and number reputation. Some phone makers and carriers also use Hiya’s technology behind the scenes.
Hiya is useful when spam comes from repeat scam numbers. It tends to be less intense than Truecaller. Its interface is easier to understand. That said, its SMS filtering features can vary by device, country, and app version. A user may install it expecting one perfect spam shield, then find that the main value is call screening.
For most users, Hiya is better as a support tool. It is not always a full replacement for the iPhone or Android message filter.
Which Option Should Each Person Choose?
- Best for privacy: Built-in iPhone or Android filters.
- Best for heavy spam: Truecaller, especially on Android.
- Best simple add-on: Hiya.
- Best no-cost setup: Built-in filter plus manual blocking.
- Best for scams from unknown numbers: Android spam protection or Truecaller.
Built-in filters should always be the first step. They are free. They are already on the phone. They do not add another company to the user’s privacy concerns. If spam keeps coming daily, then Truecaller or Hiya may be worth testing for a week.
Smart Safety Tips
- Never tap links in surprise delivery, bank, toll, or tax texts.
- Do not reply with “STOP” unless the sender is a real company.
- Forward suspicious texts to 7726, which spells SPAM on many carriers.
- Keep iOS, Android, and messaging apps updated.
- Review the spam folder weekly, since real texts can land there by mistake.
FAQ
Can an iPhone block all spam texts?
No. It can block numbers and filter unknown senders, but new scam numbers can still appear. Apple’s tools reduce clutter rather than remove every junk text.
Is Android better at blocking text spam?
Often, yes. Google Messages has strong spam detection, especially for SMS and RCS. Results still depend on the phone, country, carrier, and message type.
Is Truecaller safe to use?
Truecaller is widely used, but it may request broad permissions. A privacy-focused user should read the permission screens before turning on every feature.
Is Hiya better than Truecaller?
Hiya is usually simpler. Truecaller is usually stronger for large-scale spam identification. The better choice depends on how much spam the person gets.
Should blocked texts be reported?
Yes. Reporting helps phone makers, carriers, and app databases spot repeat scammers. It also improves future warnings for other users.
