Ok, I could be mistaken, but I think you will find that if the recipient has the necessary hardware....ie a Caller Display enabled Landline telephone and they have subscribed to BT's
Caller Display Service, then if you call that UK number from anywhere overseas, it will in all probability show up on their display as
'International' or even possibly
'Number Unavailable'. In each case if the recipient dials
1471 after the call is terminated then they will hear the following message "
You were called at [the time the call was received].
We do not have the caller's number to return the call".
If you dial the recipients UK landline number from your mobile handset whilst overseas, I think you will find that it comes up
'Number Unavailble'....but if you dial
their mobile from
your mobile then
your number will be displayed on
their handset and they will have no idea whether you were calling from the UK or from Tim Buck Too ( does such a place exist

) However, that will of course be a
VERY expensive way of calling back home, unless you use a spanish sim card. So I would not recommend doing that.
If you use a Public Payphone from Overseas, I am positive that it will be shown on the recipients telephone display as
'International', but I don't think it does if you use the telephone in your Hotel Room or in Reception, as the call is routed via the Hotel's telephone exchange.
If you buy one of those Prepaid Calling cards ( they cost around €6) where you have to dial an Access Number and then enter a Pin Number and then the destination number from what I have been told, the recipient will not be able to see that the call is originating from overseas, but they will get the
'Number Unavailable' message on their screen.
If you use a
Spanish Sim Card to make calls to a
UK mobile it will be a lot cheaper, and the spanish number WILL be shown on the recipients mobile handset display, but I have no idea what happens if you use a Spanish Sim Card to call a UK Landline Number. My guess would be that it will be shown as
'International'. I think it all depends on how the call is routed back to the UK if you use your mobile. I do know that foreign sim cards, as a rule, do show up on UK mobiles in the UK because I have a Greek friend in Corfu who calls me occasionally and his number is
always shown on my mobile handset.
Hope that helps a little. Assuming I have not totally bamboozeled you, because I think I have myself
