Hi Bartosz.

For the US please be aware that Three UK has only 3G roaming there making it pretty useless for many local markets now. For instance in New York City T-Mobile has refarmed all its 3G on 1900 MHz to 4G now and only offers basic 3G data on 1700 MHz which most non-US devices can't cope with on 3G. The advantage with Three UK is that you can switch US networks between T-Mobile and AT&T. Now depending on state and frequency either T-Mobile or AT&T is better. But 3G has been generally thinned out in the US and it feels more like 2G/EDGE in Europe now.

With every local SIM card in the US you will have 4G/LTE and speeds equal to Europe, if you have a device that can deal with US bands. Note that most European Hotspot routers don't, but you can also use tethering through an iPhone or high-end Android phone that usually do. We had a lot of disappointing comments about US roaming on Three in the last years, though it may be still good for basic data depending on location. In the US pricing for data is a bit different to Europe: small packs/amounts are expensive, big plans/volumes are cheaper.

For European use, a Mobile Broadband SIM is recommended for roaming through a tethering device. On a Smartphone SIM you'll risk being blocked (for tethering) outside the UK. Be aware that Three is also known for enforcing the 4-months deadline on permanent roaming. So if you are going to use it more (in time or volume) outside the UK than within, you'll risk surcharges after 4 months. It happened to some users, but not all.
