Does Samsung Instinct M800 require secure packages within Sprint?
Does Samsung Instinct require certain plans from Sprint like "Simply Everything" plan, or "Everything"...etc.?
Answers: Yes, no situation where you buy it the Instinct must be activated on any the everything 450, everything 900, or everything unlimited plan. The phone is crippled without internet access, so they force you into the everything plan. Even if you found a way to go and get an Instinct unactivated, they will recognize the ESN (phone's serial number).
Yes. Simply Everything or the Sprint Family Talk/Text/Data plan. There is no point in have an advanced technology phone like the Instinct if you don't have access to everything it can do.
