Beginning to think the idea of using a German mobile for SMS confirmation from UK institutions is a non-starter.
Although I detest smartphones, I do have an iPad (not with a phone capability but just WIFI). So if I can get SMS confirmations via my iPad, the Vyke app would be VG. However, I'm not clear about, "£16/year to transfer your UK number to them and then you can receive calls and texts, and make cheap calls." So perhaps I would first have to "own" the existing mobile number - the number that was issued by the UK provider. I think this is what people do when they want to transfer their existing mobile number to a different provider. I've heard there is something called a "PAC" that enables such transfers.
There was a time when you could identify a provider by a number - one prefix for EE, another for Vodafone and so on. But if people are transferring their number, I guess this is no longer the case.
One other thing: would it matter that the number that I would want to use for Vyke, is currently assigned to a basic mobile and not to a smartphone?
Is anyone on the forum using Vyke in the way that I propose?
