Usually "airtime minutes" mean exactly that. Whether the call was incoming (someone else called you) or outgoing (you called someone), you're using airtime minutes.
Some plans may have an option (it used to be reasonably common, but I haven't seen it so much lately) where the first minute of incoming calls was free, but you started getting charged after that.
You should consult your contract for the details of how your particular plan works.
Ask your cell phone provider, but usually you can.
The phone that is the cheapest from the provider O2 is not worth having. The coverage is very small and the phone drops calls often. The best phone is the mid grade and get the mid grade provider.
For a call, only if you answer the phone. They do charge you per each text message though.
There is usually not a cost difference between the provider and the dealer. Check both places before placing an order. Yes, a cell phone dealer will charge more than a cell provider. This is because with a cell provider you will likely sign or be on a contract with them where they will make the full price of the phone eventually.
You can get a copy of any previously issued bill (which usually itemises calls) by contacting your service provider. They may charge a fee for old bills.
Just that - incoming calls. When someone calls your mobile phone number, this also eats up your 'anytime' minutes during peak use times.
A toll-free number has no long distance charge associated, but calls from a mobile phone (cell phone) will still incur airtime charges, the same as local calls.
The number if texts and/or calls is dependant upon the specific package a person has opted into, and is set by the network provider - not the phone itself !
900 lines are premium rate telephone numbers which charge far in excess what you would expect normally to pay to make a phone number. Part of the call charge is paid to a business provider, so the business is funded by phone calls made.
