You can add unlimited browsing for £2 a week, but he will need very little internet use so I wondered how much occasional short periods of use would cost.
If it only costs £2 and its unlimited then why not add it, if its 60p a mb then as soon as he has used 4mb he has spent more than the internet bundle costs
£2 a week doesn't sound much but that's £8 a month! I would maybe see how he goes with it and if he ends up using more than £2 worth per month, then add the bundle on. :)
He's getting a new phone for his 18th, and it will have Wifi capability, so I don't think he will need to go on the internet via mobile signal very often - if at all.
As a result £2 a week would probably be a bit of a waste.
