No, not in most countries in the EU and UK. But the license the casino uses can have its own restrictions in offering online gambling to certain countries. So, if you experience an IP block when visiting the website, it's probably because you are in a country that the casino can not offer their services too.
If you want more control over how much you play for, it might be a good idea to invest in a Paysafecard. This is a prepaid visa card where you choose how much you want to refill. Otherwise, Skrill and Neteller offer fast and secure solutions without being directly linked to your bank account.
In principle, you should never use payment information belonging to another person. This may result in you being banned, or not being able to withdraw any winnings without the owner of either card or other payment methods you use, also verifying their identity.
Yes, both Evolution and NetEnt's live casino is well adapted for smartphone users. What you have to think about first and foremost is whether your phone support such games, and that you have good enough speed on your broadband. If you have poor coverage where you are playing, you may risk the game hanging or ending at an unfavorable time.
If you are mostly looking for traditional games like Blackjack, Poker, and Baccarat, it doesn't matter which provider you use. But if you want more variety, and in addition to exciting games you've never tried before, Evolution Gaming is above and beyond everyone else.
