I don't see why you have to be in the UK.
Sure, the PAYG sim would have to be posted to your registered UK address, but from there, can someone send it on to you?
You also need to top up the PAYG sim to activate it which can be done through a website, as indicated in this post Guide How to Top Up (PAYG)
