I bought a Samsung Tab 10.1 3G version in Fethiye this year. It was about £50 more than in the UK but the warranty is here, not in the UK. Don't know about having to register a UK one here but when I tried to buy a SIM card for it here they wanted my passport! so did not bother. The main reason for the 3G was for when we visit the UK and visit/stay with family, who do not have internet, or when we travel across Europe, we can still access said internet. Fi did this a few weeks back, went to phone shop (in UK) to buy SIM cards for phone and Tab and was told she did not need both. Just get 3G card for phone and then 'tether' tab to phone and hey presto internet access for Tab through phone. He showed her how to tether and it works. So if you have a modern phone (iphone Samsung Galaxy etc) you don't need 3G sims for both, just tether the tablet to the phone.
