Hello everyone. So I have been diving quite deep into the world of greyhat / blackhat SMS. I currently run an agency that sends lots of outbound messages for real estate investors / agents (basic questions about selling their house). I need to ideally ramp up to sending around 50K SMS per day. Twilio costs are obviously super high which is what I mainly use.
In terms of building my own modem / sending hub, I have a few concerns that I really can't find an answer to.
Let's say I have a 256 card pool modem I'll be sending from.
1. Does it work for two way sending? I would need to be exchanging multiple texts back and forth with the leads
2. Where do I source 256 SIM Cards in bulk? And then you pay $20-$40 / month for unlimited texting plans as well?
From what I know. If I have around ~100 msg variations to spin up to avoid spam detection, maintain the health of the sim card staying well under 150 - 100 / day in sending, and also vary the sending time intervals and even rotate modems, is this setup achievable?
I know this is a lengthy post, any expertise would be huge. Thank you guys
