This travel phone/modem adapter allows a North American RJ-11 landline phone line to connect to a Danish/Portugese type phone socket. This adapter is of no use for cell phones, just landline phone, fax or modem lines. The adapter is duplex, meaning that there is also a socket on the adapter of the same type as the plug, so that the foreign phone can remain plugged in.
The Danish/Portugese phone socket is also sometimes found in the following countries:
the Faeroe Islands /
Greenland /
Malawi
Simply unplug the foreign phone, and insert the travel phone adapter into the Danish/Portugese phone socket. Then plug your RJ-11 phone cord into the adapter's RJ-11 socket. You can also plug the foreign phone back in via the adapter's Danish/Portugese socket.
