The 6110 was GSM900, it's dualband version, which your sister had, was designated 6150. I do still own both and the 6150 is still working in my car kit. There was also the 6130, a GSM1800 version and the 6190 for GSM1900. These were great phones and the first ones that could receive logos and ringtones by SMS. I still hate me for neglecting the idea of setting up a logo and ringtone service, which we had brought to a running Linux system with a friend already in 4Q 1997, when we decided no one would actually pay money for having a damn logo in his display, when anyone could do that himself for free with a cheap datacable. A couple of years later logos and ringtones became a multi-million industry.

At the time it was quite an expensive handset and really the fact it was dual band was marketed as such a big deal! It was with Viag Intercom who were a small GSM 1800 network in Germany but had some funny deal with Swiss telecom (I think), so that their customers could "roam" on the larger D1 network in Germany who were on GSM 900. (Hence the real need for dual band phones even for customers who didn't roam internationally). I think calls made on the D1 nework incurred a 10 Pfennig surcharge or something. Perhaps someone else remembers the details better?

Viag Interkom (today O2 Germany) still have a national roaming agreement with T-Mobile, which will finally end at the end of next year. However they soon realized the roaming option directly with T-Mobile. Earlier - as you mentioned - Viag had dual-IMSI-SIMs, which had a Viag IMSI and one from Swisscom, which was used for national roaming on T-Mobile, since a direct national roaming faced opposition from T-Mobile and Vodafone also due to legal issues.
