- Disabled VoLTE or SMS features.
- Throttled routing performance (carrier firmwares often have buggy NAT).
- No Telnet/SSH access for advanced tweaks.
- Hidden IMEI repair options (critical if your original IMEI is blacklisted).
- Official unlock code (carrier/manufacturer): safest, reversible, preserves warranty in many cases; cost/time vary.
- Software unlock via admin UI (PIN/PUK/unlock code entry): low risk if supported.
- Firmware replacement with unlocked/custom ROM: higher risk; may remove carrier apps and restrictions; needs correct build.
- NV/EFS patching (editing network lock flags): moderate risk; targeted, less invasive.
- Bootloader exploitation/jtag/serial flashing: highest technical risk; used if device is hard-bricked.
