British MVNO The Peoples Operator is, according to MVNODynamics headed for a US launch.
This EE MVNO is relatively popular with Poundland shoppers in the UK, mainly because you can activate a new sim and get three months of plentiful data and loads of minutes for about a fiver a month - after which the price shoots up to about £15 a month.
When this happens, customers have typically ditched the sim and got a brand new one so that they can rinse the data out of it for another three months.
The Peoples Operator (TPO) prides itself on donating 10% of your top ups to charity, though it's a good idea to pick a charity from their list, otherwise it'll go to their default charity, which may not be to your particular taste.
- TPO uses the term charity rather loosely: The Labour Party and trade unions are amongst their "charity" options.
As you can tell, this is a very left wing network, and the first I've come across with a political bias.
It is unclear as yet how TPO is going to operate in the USA, but say what you like about their political leanings, they do have some good offers (though there are many people who consider these offers to be short lived and their customer service to be very poor).
It is odd that a still-to-grow UK MVNO feels that a move stateside is a good one, and there are rumours that the CEO is not to be trusted, but that's never stopped people from picking a great deal when they see one!
The US mobile industry is somewhat different from the UK's, so it will be interesting to see how this plays out.
