On our last trip I left my mobile in the car at the airport (deliberately). I knew my service provider would have charged me a fortune to make/receive calls and even more if I tried to access the internet. Plus if anything worrying was going on at home. I didn't want to know :-)
This time though I'm taking a phone with me (it's unlocked) and I intend to buy a local sim, use it for the time we're there, then give it away on our last day. It's a Samsung smart phone.
Any advice on which sim to buy? Where from? Topping it up? (we'll be in Kololi). Call charges to from UK? Charges to access the internet? Will I get a strong enough connection to access the internet?
