Where can I refer to the rates for IDD services? Admin June 04, 2020 10:06 Updated Follow You may do so here. Related articles How do I make an IDD 019 call? Is IDD supported on Grid Mobile’s network? Do I have to purchase Hype Packs to use roaming / IDD services? Will I be able to use IDD if I do not have any Local Voice minutes? I understand that IDD consists both Local Voice minutes and International Voice minutes. Will both of the mentioned be deducted from the IDD & Global SMS hype pack?
