Data SIM - no number required - no mess, just use

[stoofa]

Hi,

Sorry for the subject heading - wasn't sure how to word.
Is there such a thing as a no-messing SIM with a chunk of data allowance, doesn't even need to have a number assigned to it - that you can purchase, slam in a device and use until the data runs out?
No messing about with setting up accounts to register, having to add monthly renewal information etc.
Just SIM arrives, you slam it in a device and it'll work until there is no allowance left?

I'm thinking probably not - but wanted to ask the question.

Cheers.

Thanks all - just looking for a no-nonsense SIM with a chunk of data on to pop into the car. Got a few journeys planned where I believe I'm going to have a couple of "young un's" in the car and it would be handy if there was a hot spot for them to connect to.
Not adverse to actually registering - but was just wanting something buy and chuck in.
