O2CallAlert users pay nothing to receive the SMS either in the UK or whilst abroad. Callers to an O2CallAlert user will be charged as per their standard tariff rate for a mobile terminated call, unless their number is withheld (when they will not be charged for the call).

If you're abroad you will not be charged for the incoming call, nor will you be charged for receiving the text message.

Note, whilst abroad callers will not hear the standard O2CallAlert announcement advising them that their number will be sent to you via text. Instead they'll hear the relevant network response from the foreign network.

All O2 users who do not use Voicemail 901 can use O2CallAlert. You may either use O2CallAlert or Voicemail 901 but not both at the same time.

Prepay users will receive the O2CallAlert text message even if they have no credit both in the UK and abroad.
