If you have a legitimate harassment case, then you can get individual numbers blocked in the UK. I've never heard of anyone having the SMS service completely switched off.
Also, North American mobile phone services, companies and pricing seems to suck total donkey balls if this thread is anything to go by...
Europa:
No Incoming SMS Charges.
No Incoming Call Charges.
'Free' Text messages bundled in with most deals.
Decent amounts of minutes bundled in with the monthly fee.
Subsidised phones (in most countries and by the networks, not the govt.
).
Europe 1 N. America 0
Asia's better than both, though.
