Missed calls

Until now, if your phone was switched off or if you were out of signal range, you wouldn't know who was trying to contact you. But when you activate the Missed Calls service, O2 will SMS you a list of the phone numbers of those who called. (Up to 20 unique phone numbers divided into 1 - 5 SMS messages)

Service activation

To activate the Missed Calls service:

• Send an SMS containing the keywords ZHO A to the phone number 999111.
• Or call the Customer Care Center at *11. Calls are toll-free when made from O2 phones in the Czech Republic.

The service is gradually being activated for all current and new O2 network customers.

To deactivate the Missed Calls service:

• Send an SMS containing the keywords ZHO D to the phone number 999111.
• Or call the Customer Care Center at *11. Calls are toll-free when made from Eurotel/Go phones in the Czech Republic.

Format of the SMS message

You will be notified of missed calls via SMS (up to five messages). Missed calls (up to 20) are listed in chronological order, with the most recent call listed first.

The SMS will tell you:

• the total number of missed calls
• the caller's phone number in the international format (in quotes)
• number of attempts (if more than once, in parentheses after the phone number)
• date and time of the missed call
