An SS06 device ban on Snapchat means your device has been flagged and blocked from accessing the app, often due to violating terms or using third-party apps. To bypass it without buying a new phone, try doing a full factory reset (without restoring from backup), then install Snapchat fresh and create a new account. You can also use a VPN, but this alone usually doesn’t work for SS06 bans. On Android, advanced users might spoof device IDs, but it's risky. If all else fails, contacting Snapchat Support or using a different device temporarily may help. If not then jailbreak / root.
IK you used to be able to change the VPNS location but I don't think that works anymore
