New phone contract - need lots of data but not many minutes

[GrumpyContractor]

giffgaff?

runs over O2 and no contract.

Think im paying £12 per month for 5GB of 4g and probably about seven minutes.

woth a punt for a month, if you dont like it, dont pay for another month, easy!

Mine is on the t mobile business tarrif - Samsung s4 and £36 a month for unlimited eveything. The data is only 3g though but I'm happy enough with that.

For what it's worth, I am also running some sort of Three unlimited data contract, it wasn't called "The one" or whatever, it costs me 6GBP for the base plan and I buy the tethering add-on for the months I'm invoicing (5GBP/pcm) it still end up being slightly less than the "the one" and I never use the texts or minutes anyway.
In other countries, I often purchase data-only SIMs, meant for hot-spots, iPad or whatver, even if the plan is called iPad or 'mobile Internet' it will work just fine in a normal phone, so go with whatever is the cheapest for data.
