I have been trying to get high speed internet where I live but nobody will come out here. I have been dealing with AT&T since May 7th and they keep giving me install date after install date but they never come install my service. With that being said, Can I go get a prepaid phone and a $45 card that says "Unlimited text, talk and data" and can I use that to connect my laptop to the wifi? Also, if I can, how long does the data usually last? Right now I am using a Hot Spot device that costs $10 per 2gb data but I go through that in 3 days being a web designer.
