Set up O2 Call Alert
What is it?
O2 Call Alert is a simple, easy-to-use alternative to Voicemail 901. It provides missed call information for up to four callers, at no extra cost, by sending you a text message update.
So, if you're on another call or your mobile's switched off, if you're out of coverage or you just don't answer in time, O2 Call Alert will tell you the caller's number and the last time they called.
But it's not just you who benefits from the service. Callers also hear a message telling them that their number's being sent to you via text message, to let you know they called. (Although, if anyone decides to withhold their number, you won't be sent the missed call text and they'll be told to call again later.)
How do I switch it on?
You can turn on O2 Call Alert any time by calling 1710 free from your mobile phone. And you call exactly the same number to switch it off.
Voicemail 901 users
If you use Voicemail 901 and you want to replace the service with O2 Call Alert, call 1710 free from your mobile. Then you just call the same number to switch back again. (Please note: you can only have one service or the other.)
How much does it cost?
If you've got O2 Call Alert it's free to receive the text update, whether you're in the UK or abroad.
If you're calling someone with O2 Call Alert you'll be charged your standard tariff rate unless you withhold your number, then it's free.
