Yes, you can spoof your location on Pokemon GO for free. However, the free methods typically involve either rooting (for Android devices) or jailbreaking (for iPhones). Rooting and jailbreaking give you deeper access to your device's system settings, letting you modify your GPS location. But it's important to understand that these processes come with risks. They can void your device's warranty, make it vulnerable to malware, and even cause system instability. Plus, Niantic has measures in place to detect such modifications, which can lead to bans if not done correctly.
