The standard rate is the trap. On EE's pay-monthly plans a call to the US, India, Pakistan, Nigeria or Australia is £4.64 a minute unless you have bought an add-on first. Pay-as-you-go is cheaper per minute for some countries (43p to the US, £1.07 to India) but adds a 34p connection charge to every call, so a two-minute call to India costs £2.48. Near neighbours are the exception: Ireland and Poland are 25p a minute on pay monthly and 18p on pay-as-you-go.
Add-ons fix the per-minute price if you remember to buy them and they cover the country you need. EE's International Pass drops the US and India to 3p a minute, Poland to 8p, Ireland to 12p, Nigeria to 15p and Pakistan and Australia to 21p, for a monthly fee. If you call one of those countries for hours every month, that is a good deal and we say so below. Vodafone, O2 and Three publish their own rates through country checkers and sell similar bolt-ons; check the mobile rate as well as the landline rate, because they often differ.
