Smart phone google search

[oldschoolmc]

I had a friend search towing using google and my city on a smart phone and the search results were the same as on my pc on dsl where my website is just under the paid results #1 (yea) and thanks to this fourm I am #1!!

But when they just searched (using google) towing and let the phone decide where they were all the google places for towing were for the same city but my web site was not at the top just under the organic search results.

The phone used navigator Delux, I think it is US celluar.

I don't know any thing about smart phones.

Now for my question;
Does each smart phone provider use a different gps system to determine where the phone is located when making a google app search for towing, resturants, hotels ect ect
