Besides, you can't just buy a device and use it on Sprint, you have to buy the device from them with a 2 yr. contract. You can only use it on different carriers if it uses a SIM that that means just AT&T or T-Mobile but they don't have Wimax.
You're confusing your wireless technologies. Which, in the US, is all too easy to do.
"4G" includes WiMAX, LTE, and HSPA+. WiMAX and LTE do not use SIM modules; users are allowed to provision and change services over the air (no need to call or swap SIM cards).
WiMAX is an Intel technology owned by Sprint, Intel, and Clearwire. It was a good attempt but is effectively a dead technology because the wireless carriers in the US demand near-monopolistic market control. Tech issues aside, LTE better suits their market strategy and will be the dominant 4G protocol from here forward.
Bottom line: you may use this laptop on Sprint or Clear. There is no difference between the two other than (possibly) price. 2 years from now, WiMAX will likely be dead. Meanwhile, if you live in a WiMAX market, the service can be really fast and reliable (e.g. Portland, Oregon - Intel's home market) or absolutely horrible and oversubscribed (e.g. Philadelphia, PA and many other cities).
Do NOT expect Clear to build out any additional capacity or care about you as a customer. They are dangling by a thread and desperately shaking the change out of their customer's pockets.
