  1. Dear thank you so much for your kind suppport…. please let me know can i use this device in any country now? What about in pakistan? Which network will get 4G in pakistan on that device?? Waiting ur answer

    • It is unlocked, so it will work in any country now.
      Your second question: 3G/4G ?
      Nobody can answer it, bcoz it depends on the frequency supported by the router and the frequency used by the service provider. So to know whether it will be 3G or 4G in your home country, you will have check the frequency used by your internet provider.

    • 3G or 4G depends on the frequency supported by the router hardware. Unfortunately there is no way to enable 4G will all sim as this has nothing to do with software.
