It's also kind of a moot point in the US, since things have mostly gone over to unlimited (domestic + incoming) voice calling.
As for charging for texts, that's just plain gouging and has been for a long, long time -- although that's true whether incoming or outgoing. A text is about 1/8th of a second of compressed voice data; even at the 1990s rate of 30c a minute (give or take) for airtime, that's about 1/16th of a cent worth of airtime.
Also in the US, cell numbers and landlines have the same dialing prefix... so the caller doesn't know in advance whether they're calling a cell phone. It wouldn't seem fair to charge the caller more. Elsewhere in the world, cell phones have obvious dialing prefixes, so when you call a cell phone you know to expect a higher call cost.

Dual SIM, dual active = both SIMs fully active and able to receive calls at the same time.
You're right, my mistake!
