Hi all,
Just ordered me 2 pcs of 3 PAYG sims from ebay for me and the wife while on vacation. They were activated and accounts on the 3 site created before being posted. Upon receipt and an email from me, they will top up both sims to 20 pounds each and I will order the 15 add-on for each just before I leave for vacation. I'll arrive Italy, then UK and then France/Switzerland and I'm hoping the "feel at home" plan is true to it's word. I'm expecting my two phones to come "alive" right after I boot them up at FCO in Rome. I've checked and the international roaming is turned on for both sims on the 3 website.

Any other tips to make sure things are configured correctly to make use of the feel at home benefits?

Thanks everyone.
