Hi. I can confirm Vodafone for 4G roaming in Italy on branded German Vodafone prepaid SIMs which are on 4G in Germany (CallYa), but not one of their resellers. Generally Vodafone roaming in their own networks works pretty good all over Europe. Latency and speeds are all right. But you are mostly restricted to Vodafone networks and partner networks and can't access another networks in the roaming country, most certainly not on LTE.

Telekom has a slightly different approach: There mostly two or three roaming partners are available to choose from (at least until this summer). Again, you will need to have a Telekom 4G SIM in Germany, not one of its resellers. TIM has been confirmed for 4G roaming in Italy for Telekom, but you may access Wind and other networks too, that may only give 3G roaming.
