I can tell you what not to buy 'Sim Plus' its probably got one of the best reception rates in Poland but the minute you leave the country you have to do weird things to make international calls. Like activate it and dial some weird code #111#05# (the number) #, so basically you have to write your numbers down on a pice of paper before making a call, and even then more often than not it doesnt work.
What a load of crap. Uneccesary b shit.
