International dialing
For those that are slow at math: add the $3.99 Idial feature for 20 cents min rates to England, most standard countries etc..
Even if you just had the feature for 1 day on your account, for one, 1 min call, it's saving you money.
$3.99/ 30 days in a month , feature ends up costing you 13 cents a day. I just made a one minute call to the UK for: 20 cents min + 13 cents for the one day the IDial feature was on my account, costing me 33 cents, for the same $1.49 min call.
Some people just don't see the value in anything.
