How to activate missed call alerts on your UK mobile (and check if they're already on)

Call Catcher on Vodafone UK doesn't need activation. The service is already running on your account. When someone tries to reach you and your phone is switched off, out of coverage, or busy, the network logs the attempt and sends you a free text message once your handset reconnects.

If you're not receiving these alerts, the issue is almost always that Voicemail is intercepting calls first. This guide explains how the service works, why it might appear inactive, and what to do when notifications stop arriving.

How the service actually works

Call Catcher is Vodafone's legacy term for missed call notifications. The network detects an unsuccessful connection attempt, records the caller's number and the time they rang, then pushes that information to your phone as an SMS once you're back in range. The caller hears ringing or an unavailable tone but can't leave a message unless you've separately activated Voicemail.

This is a passive alert system. You get a text. The caller gets nothing. There's no interaction, no recording, no callback prompt.

The voicemail conflict

Voicemail takes priority over Call Catcher in Vodafone's call routing logic. If you've set up your 121 service, incoming calls are diverted to your voicemail box instead of generating a simple text notification. You can check this by dialling 121 from your Vodafone mobile and listening for any saved messages or setup prompts.

To receive Call Catcher texts instead of voicemail, you need to deactivate the voicemail service through the 121 menu. Navigate to settings and choose the option to turn off voicemail completely. This restores the default missed call notification behaviour that most customers expect.

Network registration issues can also block alerts. If your phone has been off for an extended period or you've recently changed SIM cards, a restart often resolves temporary glitches. Power down your handset, wait 30 seconds, then switch it back on and wait for full signal bars to appear.

Using Call Divert for more control

Call Divert is a separate feature that forwards incoming calls to another UK number. This is useful if you want calls to reach a landline, a colleague's mobile, or a second device you carry. On Pay As You Go plans, you can typically only divert to your own voicemail; Pay Monthly customers can divert to any UK number.

Each divert type can be set independently. You might forward busy calls to voicemail but send unreachable calls to a landline. To check which diverts are active, dial *#61#, *#62#, or *#67# depending on the scenario you want to query.

Troubleshooting when alerts stop arriving

If you've deactivated voicemail, restarted your phone, and still aren't receiving missed call notifications after 24 hours, the service may not be correctly provisioned on your account. This is rare but can happen after a SIM swap or account migration.

Call 191 from your Vodafone mobile (free) or 0333 304 0191 from any other UK phone. Explain that Call Catcher isn't working and ask the agent to check your network settings. They can see whether the feature is enabled at the system level and can manually activate it if needed.

You should also contact 191 if you're receiving notifications for calls you've already answered, or if the timestamps in the SMS alerts are consistently wrong. These symptoms suggest a network sync issue that requires backend investigation.
