    Dual Sim, yes?

    What model?

    So you have data plan on both SIMs, yes? Is there voice on both? When you switch data is the new SIM getting strong signal?

    Yeah... It is not supposed to need a reboot... I'm just being a generalist here. Maybe someone in the 640Xl forum has more advice. I do not know if this is a known issue, but sounds familiar from my reading in 640XL forum or Ask a Question.

    I'm not sure if carrier brand or signal may cause less than automatic switching. I'm really believing it is not the hardware at this point.

    Maybe look through this thread: http://forums.windowscentral.com/lum...-new-post.html

    Would you like this moved to 640XL area???
