Evening all. Quick question. What are the prefix numbers needed to call an Iridium Sat phone from an Inmarsat Isatphone Sat phone.

Heading off tomorrow for a 2 wk desert trip and I have an Inmarsat Isat and my mate has the Iridium. Have tried to phone a sat phone before from mine but could never get connected so obviously I'm doing something fundamentally wrong.

Thanks

Dunc

You have to find out from the person who owns the Iridium phone if any prefixes are needed...... a lot of the cheap pre paids are USA based so you have to use a USA prefix.

Our Iridium phone has a standard Australian based mobile phone number like 0425 123 123 and some of our friends with prepaid sat phone plans have to use +61 425 123 123 to phone us..... if we want to phone them we have to dial 00118162973123123 for example.

Thanks I'll give that a try. We'll have to sit around the fire the first night and have a play.

With sat phones, it is best to always make calls with the international code. So ask your friend what his full number is e.g. +61 for an Australian registered number. I have an Inmarsat phone, so my number is prefixed with +870. By pushing the + button, you dont have to worry about 1100, as this is an Australian equivalent for the + button.

BTW , if you ring from an australian mobile phone to another Australian number (landline or mobile), you can use the +61 to start your number. It will worik. I have all my numbers in my mobile in this format. It means if I go overseas and use my mobile, I dont have to find out the international code to ring out from that country.

I hope you have a few spare thousand bucks for those calls. It is over $20 per min from memory.

toffytrailertrash are you saying Inmarsat is $1 per min to Iridium?

I think you will find it is 21.45cents per SECOND to call a 8816 number from Inmarsat.

boobook,
if the iridium phone has an australian sim card you can call it from a inmarsat phone using +61 prefix it will cost 1 unit per minute. unit cost is between 80 cents and $1.20 depending on where and when you purchase inmarsat credit.
same cost as calling my telstra mobile from inmarsat. system cannot tell if sim is in a mobilephone or a sat phone so same cost.
I do now it costs about $20 per minute to call inmarsat from my telstra land line .send emailsfrom computer instead at 50cents a pop.
have never tried to call an iridium satphone that doesnt have an aussie sim so cannot comment on cost there.
cheers

Howard it depends on what you mean when you say an Aussie Sim card.

There are several meanings to this

1)A Telstra Postpaid Mobile SIM ( 04xxxxxx) which is what I think you are referring to.
In this case it will cost the caller whatever it costs to call a mobile. PLUS $4.00 a min for the person being called.

2)An iridium number issued by a reseller of the Telstra Sat service, including Telstra themselves. Usually a 8816 prefix

This will cost the caller about $20 per min

3)a Non tesltra australian SIM

Also 8816, this will cost $20 per min and about $20 from land lines or mobiles.
