Missed call and abandoned call alerts

Answering your phone isn't always possible and with O2 Call Alert we'll send you a text message everytime you miss a call.

If you've got no coverage, are on the phone or if your phone's switched off, we'll text you to let you know you've missed a call.

We'll send you the time and date of the missed call and the number that called you.

There are two types of call alert:

Missed call alert – you can have this instead of voicemail. We'll send you a text to say that you missed a call, if the caller couldn't get through.

Abandoned call alert – this is an optional free service that works with voicemail. You'll receive a missed call notification text if the caller couldn't get through and didn't leave a voicemail message.

Please note: Missed call alert and voicemail cannot be used at the same time. When you switch on one service, it will switch off the other.
