Please be advised that there are scams selling fake TurboSIMs (aka Turbo SIMs or Turbo-SIMs) on eBay and other web sites.  These devices are not produced by Bladox s.r.o. and are something completely different with very limited fuctions. Bladox s.r.o. have been the sole producers of TurboSIMs since 2004.  TurboSIM and Turbo SIM are trade names of Bladox s.r.o.  A real TurboSIM is pictured above.  Please compare before you buy.
