The Sony Xperia Tipo Dual is exactly what I wanted: a dual SIM enabled, small quadband device with GPS. With reflection protector it can also be read in sunlight still halfway. The SIM card can be on and off at will, the GPS works well and perfectly (used effect predominates the battery) and so far the device has only one blunder allowed (contacts deleted during the update, although it Angelich nothing clears. Had the latter but exported and she could after the update again easily import).
The battery life is as good wenigtelephonierer even with WiFi 6 days and over can expect from me.
I can certainly highly recommend the unit, was already not expensive and you get it today quasi nachgeschmissen.
