Right, it's really simple 1) Get your Smartphone, make sure it supports Wifi portable hotspot and that you have a (preferably) unlimited 3G/4G data plan or enough data on PAYG. If you can't find hotspot settings, try toggling it on with this https://play.google....t.hotspot&hl=en if you've got an Android 2) In your portable hotspot settings, find the SSID and change accordingly IF NA REGION 3DS= attwifi IF EU REGION (UK/GB) 3DS= _The Cloud IF EU REGION (ANYWHERE ELSE) 3DS= NintendoSpotPass1 IF JP REGION 3DS= wifine (Advanced Tip: If you like being choosy, here's a list of all hotspot SSIDs to pick from) 3) Turn on your hotspot (On your Smartphone) 4) Close your 3DS and toggle the wireless switch on-off WARNING!

Check if your phone tether supports infrastructure connectivity before attempting this.
