I’m not sure spammers pay wholesale rates. Pretty sure they purchase the cheapest SIM cards with unlimited texts and put them in gsm modems which spam out texts.
In Australia a SIM card can be purchased retail, with unlimited texts for $5.
At 750~ texts sent you’ve already beat that wholesale rate. That’s approximately one an hour, over the month. I’d be surprised if they couldn’t pump much larger volumes.
- sn_master 6y agoWouldn't they block you or something if you send hundreds of thousands of texts to random numbers? It can't be that there isn't some kind of a monitoring system on the consumer SIM cards.
- RileyJames 6y agoHow many obvious spam text messages have you received? And how many have you reported to your telco provider.... You’re putting a lot of faith in telcos to care enough to put systems in place. And spammers will burn through sims. They are looking for the most lax network for sending. Presumably the receiving network can block texts arriving, but wouldn’t actually stop a number on a competing network from being able to send messages (but would likely flag it to them). And then there’s the time delay to be exploited. If it takes 3 days for a number to get blocked, can you send enough messages in that period to make it worthwhile?
