Bypass Telco Hotspot Limit

· #linux

TTL (Time-to-Live) is a packet value that decreases with each network hop. Telcos monitor TTL to detect and throttle hotspot usage by identifying mismatched values between devices and routers.

Why adjust TTL? Setting TTL to 65 masks hotspot activity, making packets look like they’re from a single device, bypassing restrictions.

macOS

Set the hop limit

sudo sysctl net.inet.ip.ttl=65

Linux

Set the hop limit

sudo sysctl -w net.ipv4.ip_default_ttl=65

Windows

  1. Open Command Prompt as Administrator

  2. Set the hop limit

    netsh int ipv4 set glob defaultcurhoplimit=65
    
    netsh int ipv6 set glob defaultcurhoplimit=65
