Hi. I've tested quite a few SIM cards right now and their will be an article about it in this Wiki later this year. Generally Vodafone providers from the EU have the widest 4G roaming available. You can assume that you can get 4G roaming in all EU countries from all EU Vodafone networks. But this is restricted to Vodafone and partner networks.

Telekom and Orange providers generally offer very widespread EU 4G roaming too on different networks and more options available in many countries than just one like with Vodafone.

I can confirm widespread BonBon roaming on 4G through HR Telekom's network while Telefonica is very restrictive with LTE: No 4G roaming with their O2 brands in the UK or Germany or with Movistar in Spain so far. The same is true to Free mobile in France or Three UK.

About your specific questions: Simyo (I guess you mean the Spanish) 4G roaming like Orange abroad. Drei AT (3) in contrast to Three UK quite good roaming in LTE like on Vodafone and O2 in Germany, but enforces a rigid 4-months-FUP policy.
