Which countries does not available to support by caller identification ? I have been set up and got an SMS text message confirmed 3 days ago, but it's still not working until now.
CALLER ID are available only on the following countries:
I am in the UK but it does not work.
Caller ID has been set up correctly but whenever I call a landline it says INTERNATIONAL, or Call Details Unavailable.
Anyone know why this is?
By the way I have called many UK numbers on different suppliers to verify and check
