Can i use my iphone data abroad?

Like will i be able to use the data i have, not Wi-Fi without getting charged extra? If so, will it use up quicker than in the UK?

Don't use data abroad cost ALOT

No you won't it would cost a lot more at standard rate while roaming up to £8 per mb. Best to call your network before traveling to add a bundle which will make it a lot cheaper to use.

No problem at all.
