ok, more information:
www.aql.com/sms/network_lookup.php < this checks any number against OFCOM's database
throw in a 07404xxxxxx number and it states:
Ofcom Data Network Lycamobile UK Limted Use Mobile services Change date 08-2009 |
so Ofcom class it as Mobile services, not Wifi services.
So Lyca Mobile, is a mobile sim card that only makes and receives calls routed over voip as it's classed as a voip number, it has no agreement to be a MVNO in the actual sense as it is roaming permanently, so if a Lyca Mobile number calls another Lyca Mobile sim they get charged as the numbers are never on-net.
This is probably worse than calling a satellite mobile number.
