Best option for phone/data in USA?

[Bristol spark]

Am off on a road trip start of Jan from Vegas up to Canada, to Vancouver and back down the West Coast to LA, and back to Vegas.
Duration 19 days.

I will want 4G data for Waze Navigation plus the odd call text back to the UK.

My Phone is a iPhone 6S+ which is locked to Vodafone.


I see Vodafone offer the Vodafone passport for £5/Day which then uses my normal UK allowance of data etc.
This would work out around £100, which i guess is not too bad, and may get away with a "portion" as a business expense (to make the odd business call

However i would prefer a different number, so i don't get distracted by calls!

So is there any other options available?

Also is there consistent 4G coverage through the US, and Southern Canada?

Cheers

Thanks Guys, 3 looks a great deal.

Have, ordered my unlock code, and will pop into a 3 store to pick up a Sim.

I guess i can use the Vodafone passport for the few days i will be in Canada.

The only drawback i can see with the 3 is it does not include calling USA numbers if needed.

Well i failed to get the phone unlocked, so had to use Vodafone Passport at £5/Day!

I would highly NOT recommend anyone to use an "official" IPhone unlocking service website.

Ordered on the 28/12 stating 1-7 days to unlock, paid £60.

After 7 days was told there was a small backlog.

Heard no more until 12th Feb, when they sent an email asking for another £20!!

They are refusing to refund the £60 paid!
