Mobile phones and SMS in Thailand

[Bazle 1,450]

Like a few other posters, I'd prefer that where I am when I make a call is not necessarily known to the person I am calling.  Could you (or someone) please tell me what comes up on the 'phone of the person I am calling if I make an international call.  I am from the UK and use the 02 network and am willing to put up with their exhorbitant call rate if I call the UK when I am in LOS (not going to make many calls - not worth getting 'phone unlocked, buying second 'phone etc).  So, for example, when I call the UK, does just my regular 'phone number show or is there a LOS prefix shown as well?

 

Similarly, if I dialled a landline in the UK and the person I called hit 1471 after the call, what number would they be told had just called them?

I have just returned from 10 days in Pattaya and in that time made 2 calls on my mobile phone to a UK landline. The person I was calling did a 1471 check (which gives the number of the last caller) each time and got the message that the number was not available to be given.

 

Still don't know what happens if I call another mobile number but I suspect my number would not show up.
