Roaming cost French Polynesia
 

I could not find any mention for Roaming cost in French Polynesia for the prepaid cards I checked.

I contacted Aldi and they wrote
French Polynesia is Ländergruppe 1.
You can use EU Package with normal ALDI TALK Options.

Is this the exception or the rule, even not documented in cost tables?

Word of warning New Caledonia is rarely considered part of French Polynesia for roaming purposes even though it is geographically part of it.
