Carlos' contract is up and he's thinking of getting Sprint because they have unlimited data plans. Leo says the reason why Sprint has an unlimited data plan is that it's a crappy network. There's talk they're bringing more LTE 4G coverage, it may be worth it, but their WiMax 4G is terrible and 3G is slower now. AT&T is consistently rated the fastest, and since Carlos is with AT&T, it may be a good idea to just stick with them. They're certainly no worse than any other carrier.
Leo says that Sprint's competitive position is a good thing because it keeps pushing Verizon and AT&T. But it's just not the best network out there, especially for LTE.
