I have been told a variety of different things by giffgaff. I have been assured that the phone will work onboard, but the costs are controlled by Cunard and Telenor Maritime.
giffgaff and Cunard pint fingers at each other and Telenor Maritime were silent. I therefore wrote to CEO of the three companies, hoping to get a clearer and possibly even coordinated response.
I today received a letter from the CEO Telenor Maritime. (which has been copied to Cunard and to giffgaff)
To Quote the kernel of the letter;
"giffgaff is a mobile telephone network running as a Mobile Virtual Network Operator using 02's British network. We have a roaming agreement with 02 granting access to their customers while they are travelling on ships where we have our network installed.
It is now up to giffgaff to give allowance to their customers if they can use a roaming service or not. "
"We regret to inform, that as long you are using a giffgaff subscription you will not be able to use our excellent service at sea."
So as far as Telenor think, the phone will not work at all, and that is a giffgaff business decision.
So why I have been told by giffgaff that it will work, and quoted prices, then told it would work but the prices were Cunards/Telenors business not giffgaff's I do not know. I have also been told by giffgaff to go elsewhere to find out, and I have done so.
A reply is outstanding from both Cunard and giffgaff. Note that Telenor's very courteous and clear letter to me was also copied to the two other parties. I hope their response is of equal quality.
