Public SMS activation APIs resell the same recycled numbers across 20 services, which causes accounts to get shadowbanned or locked within 48 hours. When you run your own 64-port USB/Ethernet SIM bank loaded with prepaid physical carrier SIMs ($0.60/SIM in bulk), you own the number permanently for re-verification! ### Automated OTP Webhook Parser (`smstools3`): ```bash # /etc/smsd.conf eventhandler script to push incoming OTP SMS straight to Redis #!/bin/bash if [ "$1" = "RECEIVED" ]; then FROM=$(grep "^From:" "$2" | awk '{print $2}') CODE=$(tail -n 1 "$2" | grep -oE '[0-9]{4,8}' | head -n 1) redis-cli LPUSH "otp:$FROM" "$CODE" fi ``` Your account creator bot simply calls `BLPOP otp:<sim_number> 30` and receives the verification code in `<200ms` of arrival.
