Unlimited data for $30 is very good, here in the UK all the mobile operators scrapping Unlimited data packages becuase users use too much. 4G coverage is pretty poor here in the UK with very few places getting it, however I hear you can get some pretty impressive speeds. useless too me I get no Mobile coverage let alone 3G here in Gloucestershire, Its all hills and I in a valley. Mobile coverage in general is patchy outside of towns and citys.
