How to delete apps from lost iPhone?

I lost my iPhone recently but because I have a subscription to the Guardian app, I'm still getting charged monthly. How do I delete the app from my iPhone, or cancel the subscription, if I don't physically have to phone with me to do this?

Contact them online. You don't need anything on the iphone, with the security it has and find my iphone feature, you don't really need anything else.

You could check their website & see if it is possible from there & if not email them about that.
