Emergency+ app

Ok

Further to that (now I think I know what you are asking based on other reply) - you will get GPS signal just about anywhere (outside) but if you have no phone signal on your smartphone then your phone will have no outwards communication with the outside world, what ever app you are using.

Keep in mind you don't actually have to be that "remote" to have no phone signal.

Finally, a straight forward answer which what the OP was after - thanks.

Well "Old Mate" you obviously didnt read the first reply which says exactly that in the second sentence.
Perhaps you could have answered instead of obliquely bagging the responders who gave the answer plus reasons why.

Hi

Bit of an explanation when providing an answer to a question doesn't go astray in some cases. None of those provided seem to be overly extravagant in length or complexity i.e. they all seem to be relatively straight forward even though there is some repetition.

Anyway.. the OP never provided any clues as to what sort of an answer he wanted (i.e. old mate is guessing) so I dont think anyone can be blamed for doing the wrong thing. No big deal either way. Keep on chooglin.

Cheers

Stephen, please see my answer below, it will explain things.

You dont need any app for that to happen if you dial either 000 or 112 It will go through on ANY available network.
However no signal no call
No standard cellular phone can communicate via satellite.
Note I said Standard phones. There are now hybrids which with additional hardware can do so.

Read about what the app does here.
Appears to give you info on your phone as to what to do but you have to make the call yourself.

For some smartphones a sleeve is available that turns it into a satphone. Then you need a service subscription.

There's way too much info in those replies. We're supposed to just say no and leave the thread at one word and one post.

HOWEVER A GPS enabled smartphone WILL pick up GPS coordinates ANYWHERE If it has" Use GPS satellites" enabled and so the App will give you your coordinates.
If he stated only the above he is correct to a point,
It WONT however be able to connect to anyone without signal from a tower.
IF he said after doing that it would connect to the Emergency services he is DEAD WRONG and could end up dead as well.
This is the sort of thing I mentioned in my earlier reply. To Keep it brief he is dead wrong and a complete idiot.
People could die from morons giving faulty dangerous advice like that.

Sorry, I wrote that badly. He said the phone will connect to satellites and transmit a request for assistance.

Yes I remember an ambulance officer in I think it was Coffs Harbour getting slammed for giving a talk and saying the same stupid thing and this would have been at least 7 years ago so some havent learnt have they.
Here is why it doesnt work
The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.
The Galileo Navigation System uses the L-band similarly to GPS.
The GLONASS System uses the L-band similarly to GPS.
GSM mobile phones operate at 700–900 and 1800–2300 MHz. Iridium Satellite LLC phones use frequencies between 1616 and 1626.5 MHz[2] to communicate with the satellites. Inmarsat and LightSquared terminals use frequencies between 1525 and 1646.5 MHz. Thuraya satellite phones use frequencies between 1525 and 1661 MHZ
So you can show him this as an explanation why one cant talk to the other

Hi Mike,

Here is one for the expert that thinks he knows it all.

Tell him I will take him out into the true remote bush, hundreds of kilometres from anywhere.If he can get his smart phone to get help, I will not charge him for the experience to taking him bush.

There some people that you just can not tell them anything, and because they were told it will work, it must be true.

There are many great replies above, so let him read them and then let him come back on, tell us all sorry and make him eat humble pie.....lol




Cheers
