  • If I use personal hotspot on iPhone, will it use my Wi-Fi or data plan? There are 2 computers in my house. One of them won't connect to the router. So I figure while my iPhone has Wi-Fi access, I can turn on personal hotspot and make the computer connect to the iPhones personal hotspot
  • I'm trying to use my hotspot from my iPhone for my laptop and it won't connect? The computer is a Dell Latitude D600 and I'm using a D-Link plug in. The phones Wi-Fi is showing up but when I click connect, it says "Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again." It shows full service on both the phone and computer and the phone is right next to the computer. Any ideas?
  • Can i use my hotspot without charges being added? I have a iphone 6s plus with metro pcs. I have unlimited data, i pay about 30$ monthly, i'm not sure if i can share my hotspot, do y all guys know if i can without any charges being added?
  • Does it cost extra to use iPhone as personal hotspot? I have unlimited data but I'm pretty sure it's only for my phone, not for hotspot. I've heard you get 1GB free. If I were to use this I would probably play a little world of Warcraft. Does WoW take up memory? And how can I watch how can I watch usage. Also is the 1GB free true? I have sprint btw
