Internet only comes to about $70 per month from Comcast. Not a great deal. How about tethering a 4G phone to a laptop that has a router for the other laptops in the home?
If your tethering, the cellphone companies will charge you,for coming and going, where your cell phone is concerned. Downloading from the tower, then downloading onto your device. It’s no problem, if you can keep your data to within your plan, but if you go over, the overcharges are just huge.
