What are my options if I don't want the internet service provider that my apt complex uses?

Just moved into an apartment complex that uses at&t. Well… I refuse, absolutely refuse, to use at&t again after the most horrendous customer servicer experience I have ever encountered. I'm currently tethering my iphone for a hot spot, but obviously that can get costly. Also, my phone isn't getting good reception in here so it's killing all my data. Any thoughts or suggestions?

Internet providers are sometimes geographically restricted. Do an Internet search for your address to see if you have other options.
