SMS messaging
Ion Echo, LLC sends SMS text messages only through WannaGo (wannago.vip), and only to people who have opted in. Messages are transactional: invitations to events you were added to, updates when someone responds, event confirmations, and reminders. We do not send marketing text messages.
Opting in. SMS is strictly opt-in. In WannaGo Account Settings you add your own mobile number and enable SMS notifications. WannaGo then sends a one-time verification text, and notifications begin only after you reply YES to confirm.
Message frequency varies with your event activity. Message and data rates may apply. Reply STOP to unsubscribe at any time, or HELP for help. Your mobile number and SMS opt-in are used only to deliver these notifications and are never shared with any third party for marketing or promotional purposes.
