GSM vs UMTS call quality
I def think it's the Tilt, I used a friend's Q9h and it sounded a lot better than the Tilt.
UMTS = CDM Technology
LTE = OFDM Technology
so I wouldn't exactly call UMTS GSM-like
its data transfer that is the purpose of the technology .....
so depending on the phone ...
either u have a garbage phone or bad signal
UMTS has nothing to do with anything but DATA access
this should explain it ...
GSM and UMTS GSM is the Voice UMTS is the data ....
it says it right here
its just combined calling it UMTS

No, I'm pretty sure UMTS uses a completely different interface. Really, UMTS is nothing: it's just like AT&T calling it "3G". UMTS and 3G mean nothing! All they really are, are WCDMA voice and HSDPA/HSUPA data, but being covered up by the names "UMTS" and "3G". It's kinda like people saying GSM, but in fact it's just TDMA.

UMTS allows voice and data to be used simultaneously on the same channel so there will be a difference in call quality. UMTS is a GSM core with a Wide-band-CDMA air interface. EV-DO is only for data. UMTS is voice and data.
