O2 Call Alert
If you miss a call, the O2 Call Alert service will:
You can turn O2 Call Alert on or off any time by calling 1710 free from your mobile.
You can't use Voicemail 901 and O2 Call Alert at the same time – using one cancels the other.
If you have O2 Call Alert enabled 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 rate.
