Will my iPhone camera and apps work in England?

I'm going to England for 2 weeks on Tuesday and was wondering if the camera and apps will all work. I don't care about the phone or texting part. Its an iPhone 5 and I have Verizon btw. I'd like to put pictures on Facebook and Twitter/update status/tweet etc. From my phone as well without having to use a computer.

Camera will for sure but the apps it depends on which apps and your ability to get Wi-Fi

If you want to use apps that access the internet you'll either have to find local Wi-Fi or use data roaming.

I can't comment on data roaming - that's an aspect of your contract with Verizon - but it would probably be expensive.

Lots of shops and hotels and some streets in touristy areas offer free Wi-Fi though.

Your camera will work normally.
