On my 7" Tablet after I am told that I have so many, I believe that they just AUTO download & install. You can sometimes see that happening on the upper left hand corner.

And me also rec'd my first POS 7" tablet, before replacing that one myself, for use with Skype, but I canceled SKYPE, because I got tired of hearing my Wife complain, and the PPL she called complain (I was totally fine with it), so I had ATT re-install their unlimited long distance service. No matter what, who you use>>IMO>>Nothing sounds as good as a good old Telco LANDLINE.
