Prepaid data

[got berry]

I no longer need data on my iPad. I would like to cancel my monthly plan but would like to keep some data just in case I need to have it. Is there a carrier that I can buy a chunk of data from that won't expire in 30, 60, 90 days etc, just able to use it until it's gone?

Not that I'm aware of.
