Depends if he wants it on a regular contract, judging by the wording of the OP he does.
I've seen some more than reasonable Nexus 5 pay monthly deals.
Presuming you already have a phone that does the above... could you not just switch to a sim only deal?
My house mate has just done that with her iPhone 4s and Im planning on doing it with my 5 in September when I can get an "upgrade!" would rather pay £15 a month with no contract than fork out another £41 a month for the next 2 years on the next iPhone. :/ just an idea.
I've got a Samsung S2 that tends to run out of battery every time I actually need to use it. If I plug it in over night it's run out of battery by 3pm with everything I can turned off. I suppose I could get a battery off ebay for 5.99 delivered, however fancied a change (under pressure from the missus whinging about my s**t phone)
My Moto G was £15 p/month w/ 700 mins, ultd. Texts, 1 GB of Data. Bolted on another GB of data for £2 a month.
That was with a bit of negotiation and also the fact that I've been with them pretty much since inception!
I can only imagine its cheaper now.
Motorola G+ or G. Pair with a Tesco sim only deal and you've got a winner.

Unconfirmed as yet but there are certainly rumblings!
