Guys, by the way there is no need to sign up for several plans. A week ago I bought micro sim adapter from
www.gomicrosim.com. Costs only 4.5 EUR. Really worth it. Now I can use my micro sim in both Ipad and Iphone. Should save me lots of pounds, since there is no need to sign for another plan. Highly recommend this seller, his price and delivery options are the best so far.
