Germany never had an ETACS network, they had some very bodged NMT clone and then went to GSM. Austria AFAIK had NMT but no roaming and ETACS until 2002 but I never heard of roaming. So-called D network was way cool, much cheaper than any GSM offer and the last phones weren't much bigger than GSM phones. I had one in use until 02/28/02 and was really sad when they cancelled service.
