Usually this is done in cahoots with the carrier - you’re typically buying the advertising from them. At least, that’s how it is here in Canada.

i doubt it. do carriers really sell advertising directly to their clients? ie. does the company have a advertising division where you can spam SMS to their clients within a certain radius?

Actually, yes. I was pitched by ad reps from the largest carrier - they claimed to be able to send an SMS when one of their customers enters a geofenced area.
