it depends on the Operator and where you are.  They all only use 2100
MHz for 3G, not the lower 900/1800 MHz bands (which they could do
legally after a EU regulation).  But yes, indoor coverage can be really
bad.  For example in my apartment it is difficult to have 3G of all
operators, and the one I use mostly (Eplus) barely has 2G coverage here.
T-mobile and Vodafone are generally better.

It's of course different if you're at major locations like train
stations or the big squares downtown...

Another note:  I've recently seen some operator predictions for Germany,
and they assume something like GSM being in operation until 2020 -
definitely significantly longer than the life time of their existing GSM
licenses (expiring in 2016).  This tells us a lot about the
installed/deployed user base, as well as the limited 3/3.5/4G coverage..
