We hope to have our first roaming SIMs late next week. These are the same price to get as the existing UK O2 only SIMs (£5 to buy, £2/month). They have a dual personality in that they can be O2 to work in the UK on O2 at the same prices as the O2 only SIMs (2p/min, 2p/text, 2p/MB), or can switch to an EU profile which has the same price in UK and throughout the EU at 10p/min, 5p/text, 10p/MB. The EU profile allows use on other UK networks so allowing you much more coverage than a normal UK only SIM. These SIMs do allow roaming outside EU at a higher price, which we'll confirm in due course. For a limited period, we are planning to offer these free (pay for postage only) to customers that need roaming and have got one of our O2 only SIMs. Once we have the SIMs in stock, we'll work out the details.
