The Samsung S Duos is highly recommended if you with two SIM cards on the road must be / wants. Switching between SIM cards is done without any problems and quickly and you're both always available. Only the processor speed could be higher in the existing speed this Smartphone is clearly focused's suitable for calls and not for quickly running other applications, here, patience is called for. So: To make calls with two SIM card strong buy recommendation, if it still should be quickly available to other applications, but rather walk around with two cell phones :-)
