Has anybody tried to use a Russian mobile SIM card in your Blackberry phone when traveling there? Usually, I buy a Russian SIM card there (Beeline or Tele2, etc) and use the Russian # while I am there. However, on my last trip in Piter, the SIM would not work in my Motorola RAZR, which I found odd. Curious if any have had the experience of taking their Blackberry to Russia? Thanks.
