@Snidely,

outgoing incoming rate or fair use is used by some providers if the phone is alsmost only used for incoming calls. Incoming even when roaming free seems to cost some money so smaller dealers use fair use to limit this. Making outgoing calls means they make money which compensates for incoming calls.

There will never be a problem if you use it for outgoing calls only. When using it that way you are paying them money. The ratio you refer to is only used for incoming related to outgoing calles not the other way around.
