Error	Description
Failed to establish API call	If your call could not be completed, it usually means the mobile app had issues connecting to the internet to make the phone call. If you currently use wifi, try turning it off and making the call again, or vice versa (go to Settings > Call Settings > Wifi Calling and use the toggle to turn wifi calling on or off).

Something went wrong	This means that Grasshopper was unable to complete the action you were attempting. This could be a network issue, so it's worth trying again. If you continue to encounter the error, select Contact Support.
Rate Limiting: Failed to Send Message	To prevent fraudulent use, Grasshopper sometimes temporarily limits the number of text messages a single user can send within a certain period. This prevents the recipient's carrier from blocking the user's phone number. Please wait until the temporary limit is automatically lifted (customer support representatives cannot lift it for you). To avoid this error, you can: Do not exceed the 160-character limit per message Avoid sending multiple messages in a row without engaging in conversation Use special characters only when necessary
Sign in error	If you received an error while trying to sign in to the apps or admin portal, make sure to check the following before contacting customer support: If using a VPN, disconnect and try again. VPN use is not supported and will cause issues logging in and using the apps and admin portal. Grasshopper will only work while in the US or Canada.
Outgoing texts are not allowed by carriers on an unregistered local number. Please submit your local number for registration.	SMS registration is an industry-mandated process created by carriers and service providers in response to FCC requirements to protect consumers (your customers) from spam and fraud. The intent of registration is to ensure message senders are legitimate businesses sending messages to contacts who have consented to receive them. As of February 3, 2025, carriers will block traffic from unregistered phone numbers. Learn how to register your local phone number to enable texting.
