Today we moved into our new apartment and so far no major problems! I now have a phone line and so can use dial-up internet at home. I have tested Skype only briefly and it appears that a dial-up connection works but is not very clear. I shall keep experimenting with it.
I don’t know exactly what needs to be dialled to get through on the phone from abroad, so I am afraid you will have to Google that to find out what it is from your respective countries.
