If being used on sprint in us, do you need the sim to activate?

Is the sim used for their wimax network? If yes, then it probably needs to stay in to utilize that network. Sims used to only be used for roaming on gsm networks outside of the US, but that is not so anymore. Sprint uses their CDMA network still, as well as wimax and ther LTE network also. Some of their newer phones may utilize two networks for handoffs when one or the other does not have a strong signal.
