Hi Andrea,
Cheers for that, I'll look into it. Here's some more info for you and all others
Home - At home I use Swiftcall. We pay £19.99 a month and all calls to the USA & Canada, along with 15 I think other countries are included (oh and ALL UK geographic numbers too!). only limit is after 75 mins it cuts you off. You simply redial the 0800 freephone access number, punch in your Pin and redial the destination number. Calls can be made from your registered Home landline and crucially, off one nominated Mobile as well. Seeing as 08 numbers are included in my O2 pay monthly plan, even during peak time, I can call various family, freinds and business contacts in the USA for 'free'!
Peak Time / away from home.
Again, taking advantage of the included Access to 08 numbers, I sometimes use Swiftcalls 0870 028 0463 access line, which between hours of 9-5 provides calls to all over the world (with some exceptions I beleive) for 'free' - you just pay whatever your landline or mobile provider charge for 08 number access.
Another similar place I use is
http://www.yourcallworld.com/default.aspx - again, I take advantage of O2's included access to 08 numbers to call their access line, from which I can make calls all over the world (so all my India and China, Japan, Malaysia contacts become available) - look carefully into their latest offers for other networks, they're seemingly providing 07 access asa well.
I'm also trying to find time to evaluate the newer VOIP solutions to see if they provide good value, performance and service for the much cheaper rates they advertise. I'll let you all know once I get time to do that along with the 743 other things I mean to do!
I occasionally do go over my included 1000 minutes on my O2 mobile plan, and the most I've had to pay extra has been around the £15 mark.
What I like most about our home Swiftcall package is that we can pick up the phone, dial and not have to even think about 'ohh how much was that going to cost' at all!
