Snapchat device ban

ONLY snapchat can remove the ban they have put on the device.

Historically, that is extremely unlikely to happen. The device in question was used by someone to repeatedly violate snapchat's terms of service. When that happens they will permanently ban the device from using their service.

If you bought it used, try to return it and get your money back and go buy a new phone instead.

If you are the original purchaser of the phone... well, whatever you did ticked snapchat off to the point that you might as well find a different service, because they are not going to 'un-ban' your phone.

No. You need to contact Snapchat for this.
