Many thanks for that. Form was duly completed earlier this afternoon. I shoud be back in the UK next week so will be able to pick up the SIM and a new phone to put it into.
As for dropping it in the first place, it was complete muppetry, guilty as charged.
Having recently switched from another provider, I have been very pleased with the Virgin coverage in the UK (Solent area). It was a bit of a struggle to deal with the main Virgin Web Site on this matter, but at least I am now a member of this Forum.
