Thai Cellphone Caller ID's -- How to Avoid 'Em?

[Casper 0]

A hypothetical question:

 

If i was going to call a girl having arrived in Thailand a few (well, ok a week) before I said I was going to, will my hotel show up on her cell phone?  And if it might, how could I avoid it (here we can enter a code that lets the call remain anonymous).

 

Any help appreciated.  This is out of my area.

if you stay at a small hotel and they only have one phone in the lobby it's possible that the number will show up. if the call is made through an exchange. ie from your room  and goes through a switchboard then 100% no number will show up on the cell phone
