Got some more details on Vectone. It is another virtual network, similar to those others started in the Netherlands.
Vectone Mobile Signs MVNO Deal with T-Mobile UK New 3G MVNO for Ethnic Groups
The likes of Lebara, Lycatel etc. are targeting the ethnic communities as the pre pay cards people used for calling abroad now move to mobiles. The way I see it, whereas before you had expensive normal phones and pre paid calling cards, you now have expensive calling cards or Skype out subscriptions.
As most immigrants don't have traditional phones, then there is a need to move pre paid international calls to mobiles. I think this is where they are fitting in.
At 5p, it significantly undercuts Asda (8p) though is marginally more expensive for SMS (5p versus 4p) which does not matter for me as I only send a very few texts.
I'd like to go Asda and might well do so, but with PAYG and number portability in 2 days and with no discounts for more than minimum purchases, you can just run £5 at a time and dump them if they screw up.
For me it is Vectone or Asda at 60% more expensive ?
