Surface 3 (Black) 4GB RAM 128GB Storage You can insert a SIM card and carry it around, so there's no need for the troublesome tethering. Comes with a stick-on case. Also includes a separately sold, non-genuine charger. The original key pad is sold separately, but I'll include that too. I only used it for work in the past, so the battery is fine. It's a good deal, so please consider buying it!
