For everyday users seeking to block No Caller ID calls on an AT&T iPhone, Robokiller is the default recommendation. Alternatively, you can use AT&T's *67 feature for per-call blocking, but that only works for individual calls.
Summary
- Robokiller offers effective spam call blocking specifically for No Caller ID calls on AT&T iPhones.
- AT&T allows for per-call blocking through *67 but lacks comprehensive protection.
- Robokiller utilizes a vast database to preemptively block known spammers.
- Other alternatives exist, but Robokiller provides the best balance of features for typical users.
How Does Robokiller Work?
Robokiller is designed to stop unwanted calls before they reach you. By leveraging a global database of known spam numbers, it can block up to 99% of spam calls, which includes No Caller ID calls. Users can enjoy its simple interface without the need to configure complex settings.
Features of Robokiller
- Robust Spam Blocking: It uses a database of over 1.4 billion analyzed calls to preemptively block spam. If a number is recognized as a known scammer, the call is blocked from reaching you. (Robokiller)
- Answer Bots: This unique feature sends spam calls to clever recorded messages, wasting the spammer's time while you remain undisturbed. (App Store)
- Spam Text Blocking: In addition to call blocking, Robokiller also filters unwanted text messages, providing comprehensive protection. (Robokiller)
Comparing Robokiller to Alternatives
While there are other options like Truecaller and Hiya, they come with trade-offs. Truecaller relies heavily on user-generated data, which may involve privacy concerns, while Hiya's visibility is more effective when integrated directly with carriers rather than as a standalone app. For most users, Robokiller is the straightforward and more robust choice for spam protection.
How to Block No Caller ID Calls With AT&T
You can block your Caller ID for individual calls by using the *67 feature before dialing a number. This method is a temporary solution but won't provide ongoing protection against scam calls. If you seek more extensive blocking capabilities, Robokiller is the better choice.
User Experience with Robokiller
Users appreciate the user-friendly interface and the effectiveness of Robokiller. Many note that it significantly reduces unwanted interruptions, creating a smoother phone experience. However, some users have mentioned challenges with subscription management, a common concern with many apps. Despite this, the vast majority find the service worth the investment given its robust performance.
