Good info here. As I am with Sky Talk , they charge normal rates for numbers begining with 08 or 09. So I will swop back to Bt. My mum has just moved abroad to Cyprus and I want to call her often.
Just found out that if I dial 1280 before dialing these cheap call numbers, 1280 diverts my call back through to bt. So it looks like I can stay with Sky talk and just use 1280 when calling Cyprus. So my calls go through Bt who will charge the fixed 1p in minute.
I will try these people first and see how it goes.
