CallBlocker support

Contact All Nighter Labs

Email support@callblockerios.com with your question. For a technical issue, include your device model, iOS or iPadOS version and the message shown by the app. You do not need to send your call history or a recording to ask for help.

Which devices can use CallBlocker?

• Import, suggested ranges, manual rules and blocking: any iPhone that runs iOS 26.0 or later. Apple lists the iPhone models compatible with iOS 26. The one capability the app needs is on-device text recognition, which every one of them has.
• Reasons written by Apple Intelligence: iPhone 15 Pro or 15 Pro Max, any iPhone 16 or later model including iPhone 16e, or an Apple Intelligence-capable iPad, with Apple Intelligence turned on and its on-device model downloaded. Without it CallBlocker writes the reasons itself from what it read, and nothing else changes.

Apple Intelligence availability depends on device, language settings and region. The device and Siri languages must use a supported matching configuration. The explanations it writes are in English. See Apple's current requirements.

CallBlocker is for iPhone and iPad. There is no Android or Mac version.

Set up blocking and import your Recents

1. Open CallBlocker and follow its two setup steps. The second sends you to Settings → Apps → Phone → Call Blocking & Identification, where you turn CallBlocker on. On iOS 26 the Open Settings button sometimes lands on the main Phone settings page instead; follow the path from there. Come back to the app and it checks the switch.
2. Capture your Recents. Open Phone → Recents, take a screenshot, scroll one screen and take another, letting a row or two overlap, as far back as you want checked. For a long list, start a screen recording from Control Center instead and scroll slowly, about one screen every two seconds: numbers that flash past cannot be read. How to Capture, in the app's menu, walks through both routes. Apple explains how to record your screen.
3. On the Review tab, tap Import from Photos and choose all the screenshots at once (up to 50), or the one recording, but not both in one import. Only what you choose is read. A row in Recents that shows a name but no number gives the importer nothing to read.
4. Review the ranges. Each one shows its pattern, how many numbers it covers, how many of them called you, a ruler drawn to its size with a tick for each caller, and a sentence saying why it was suggested. Untick anything you are not sure about, then tap Block. Close dismisses the rest. Nothing reaches iOS until you tap Block.
5. The Rules tab lists every rule with a switch, its size and where it came from. Its status row says when iOS last took your list. Tap + to write a rule yourself: start with + and the country code, and put each * at the end, one per digit. A rule covers at most 10,000 numbers (four wildcards), and all your rules together at most 180,000.

For Apple's own blocking settings, see Apple's call blocking guide. If you want Apple Intelligence to write the explanations, turn it on in Settings → Apple Intelligence & Siri and let its model finish downloading. The ranges are the same either way.

When something does not work

The review screen mentions Apple Intelligence.

That note is about the sentence beside each range, not about whether you get ranges. "Found by matching the numbers that called you" means CallBlocker wrote the sentences itself. If you want the model's wording, check the device model, software version, Apple Intelligence setting and language configuration, and give a pending model download time to finish; the next import uses it. A software update cannot add Apple Intelligence to hardware without it.

The import found numbers but suggested no ranges.

A range is suggested only when at least two of the numbers you imported share it, so a first import of unrelated numbers can suggest nothing. That does not mean your callers are safe. Capture further back, import again when more calls arrive, or add a number by hand on the Rules tab.

The import found no numbers, or fewer than the screen showed.

Numbers have to be readable: no zoom, the list in full, and nothing scrolling past faster than it can be read. A number seen in only one frame of a recording is skipped, because a blurred mid-scroll frame can misread a digit, so scroll slowly enough that every row is on screen twice. Rows that show a contact's name but no number give the importer nothing. For a short list, screenshots are the surer route.

CallBlocker's switch is missing from Phone settings.

That switch is registered by iOS after the app is installed, not written by the app. Open CallBlocker once, restart the iPhone, then check Settings → Apps → Phone → Call Blocking & Identification again. We explain the registration and load failures in detail.

A call still rings.

Open the Rules tab. The status row says whether iOS has taken your list; if it shows an error, tap Try Again. Check that the rule's switch is on and that the full incoming number, including the country code, fits it. Then check Contacts: since iOS 18, iOS does not block a number saved in your Contacts, whatever your rules say, and nothing in the app can change that. A caller whose name shows when the phone rings is the tell. A number outside your ranges, or a hidden caller ID, is outside what a number-based rule can match.

A call I wanted was affected.

Switch the rule off or delete it on the Rules tab; the block list updates as soon as iOS takes it. A broad range includes numbers you want. Check Apple's own screening and blocked-contact settings too if the problem continues.

A blocked caller left voicemail.

CallBlocker does not control voicemail routing. Apple says blocked contacts can still leave voicemail. Ask your carrier about its voicemail and network blocking options.

The widget's monthly count looks low.

The Home Screen widget shows how many numbers your rules block and how many calls were blocked this month. The monthly count is what CallBlocker noticed while it was open; iOS does not report calls it blocked while the app was closed, so the count runs low. The blocking itself is not affected.

Clearing what was imported.

Clear Imported Call Logs, in the Review tab's menu, deletes every number and label read from your screenshots and recordings. Your rules stay. The screenshots and recordings themselves are in Photos, where you delete them.
