When the user travels, the user may be provided with telecommunications services by another service provider operating in a wired visited fixed network. The user “attaches” himself/herself to the visited fixed network which includes nominating a telephone to which calls made to a user's personal number may be forwarded. The user is also assigned a prefix number which enables him/her to make calls from any phone in the visited fixed network.
