Answer 1

Start reading the documentation – or a book like “c# in 21 days”.

• System.Threading is your namespace for threads. Opening a thread is trivial, but I would not go that way.
• Look into ThreadPool and queue a WorkItem for every SMS. The ThreadPool will automatically start threads. This is more memory efficient than using static threads, especially if you use that in multiple places of your application (as threads may get shared).

There are ample of samples for using WorkItems.

is a decent start documentation wise.
