i m going for some work to saudiarabia so what will be the call rates to india from iphone using skype
Skype's rates to call India are at 9.2 US cents/minute, for landlines and mobile phones. Skype bases its rates for where you call, not where you are located. I (in the USA) would pay the same 9.2 US cents/minute to call India as you would from Saudi Arabia.
You can change the currency for the rates on that page, if you want to see something other than USD. If you use your iPhone on a 3G network in Saudi Arabia, there could also be charges for using the data services of that mobile network (or roaming charges, if your iPhone has a number from outside Saudi Arabia).
