I'd recommend calling our mobile support team on 0800 079 1133 as they'll be happy to discuss what we can offer you to increase your data allowance. I can't guarantee we can offer you a new customer deal however we do often price match existing customer offers to new customer ones.
Definitely worth a try ringing as I'm sure we'd be able to tempt you with a good offer.
Let us know if you've got any further queries.
