Answer: "Which telco provider offers the cheapest IDD call rates?"

It's an easy win for Digi in the battle of cheapest IDD call rates! U-Mobile is close behind, offering rates that matches Digi's in some areas. Celcom is a distant third while Maxis is far off the mark, not winning any categories/countries that we have selected.

There you go. Digi, the undisputed affordable IDD call rate champion.
