Why is this not apparantly allowed to work? I see zero difference if you are abroad calling on wifi to being in the UK. The cynic in me thinks its to generate extra income for O2 on travel bolt ons etc
Surely from a customers point of view being anywhere in the world and able to call people as you could at home through wi fi out of your allowance is a good thing..!?
If you dont turn your network on aborad only wifi it could still work I assume?
It used to work abroad when we had Tugo but that was stopped and probably as you say, because of lost revenue.
No matter what you try now, it will not work outside of the UK.
There are few reasons all technical to not getting to work....
Latency - OK in some of the EU, rest of the world back to the UK can be dire and impacts performance, and for voice you normally use QOS (quality of Service Markers, this will be the main one.
Packet Loss across the wider Internet, if ever you have done packet traces across the internet, you drop packets left, right and centre, again this affects voice quality.
Wifi Speeds are only one part of the equation:
wifi + local network + global peering networks+uk and back = VOIP issues.
There are many more, so from a Tech point of view i can see why they dropped.
