Yes, it was a nice sales pitch, theric . . . And unfortunately, bob's information is misleading...

Yes most carriers may allow you to move from state to state if they are licensed in those states, but they will want to reevaluate or underwrite your policy if you do! If you have acquired some disease in the meantime, they may decline coverage or put you in a high risk pool at a high rate. Many insurances with the same name are still not portable state to state without underwriting a new policy.

No networks means freedom of choice---the insured has the opportunity to choose their own doctors, hospitals, and medical treatments. "no network" does not necessarily mean that there is no negotiated, contractual discounted fee for all medical services. For example, insurance companies who offer an open plan, as theric suggested, usually have contracts with all the big medical networks, but if the insured chooses to go to a specialist of his or her choice for the best medical treatment available who happens to be out of all of those (or not even in the same state or country), there is insurance coverage available for him or her, even if the cost may be a little higher. Being limited to a network means the insured may not have insurance coverage if they want that same specialist.

In many states companies are allowed to single an individual for rate increases. Some can only increase rates by class. For example, there is a candidate for state representative in englewood, florida, who is running in order to try to change state law. She had been paying something like $220 a month for insurance, got cancer, and had her rates go up to about $1800 a month. Most individual policies (and small groups) do act like car insurance---the rates go up if you file claims. Each person needs to check to see if their state allows their rates to be raised individually---read the policy carefully, especially the sections on rate increases and termination clauses.
