Voda's SIM needs to be less than about two years old to handle 3G. If
you are on Voda check their Support. The forgotten the number it has
to be higher is 89610300000734 and last time I spoke to them it
pretty much encompassed most of their new cards since they introduced
2.5G from memory. Sounds like yours may not handle 3G. Should be able
to swap and upgrade for free as most telcos will count on you using 3G
services like video calling for which they can charge you more.

Can you say specifically which ones? I haven't found anything I can't
do with my old SIM card yet. High-speed data, video calls etc all work
fine. What am I missing out on?

Its a normal postpaid SIM card issued by Globe Telecom in the
Philippines. I'm not sure what you mean about cutting the SIM.

Fitting two SIM plus an adaptor into a space inside the phone designed to
hold only a SIM plus battery is an engineering challenge.
The approach some dual-SIM adaptors take is to make the device the size of
the SIM card itself. To fit your original two SIM cards into it, you must
trim them using a scissor, retaining essentially just the area where the
gold contacts are. These cards usually provide templates to guide you. The
procedure is not with out risk, but has, apparently, worked for thousands
of people.

Which means "all" their "normal" SIM cards are USIMs

If you can make video calls then you are a 3G customer using a 3G SIM
already

Or to be correct, their (physical) UICC contains a (logical) USIM.
