Hi guys just wondering if there is a stand alone device that you can put your sim in to use as a hot spot? When I'm at work I like to use my ipad which is wifi only and my mobile only has 2gb data allowance. I have a contract sim with unlimited but it's a micro sim which don't fit in my phone. ANYWAY lol is there something I can put the sim in and use as a hot spot that is cheaper than buying another phone ? Thanks in advance.
