This new MVNO, '
Delightmobile,' seems to offer good value for certain international destinations, eg 1p a minute to landlines in : Brazil, Colombia, China, India, Indonesia, Kenya, Kuwait, Latvia, Lithuania, Malaysia, Morocco, Nigeria, Pakistan, Poland, Romania, Slovakia, Slovenia, Turkey, Uganda, Vietnam and the UK. Calls to mobiles in India and Pakistan are also apparently 1p a minute. Furthermore, they offer unlimited calls and texts to others on the same network for a monthly top up, as well as 1000MB of mobile internet.
Treat bundles are available for a month, and on the face of it seem to offer good value, eg: for £5 you can get 100 minutes / texts to all UK networks, plus unlimited same network calls and texts, and the 1000 MB internet allowance.
