The useful starting point
An accepted SMS request is not the same as a delivered message.
Start with the right information
Configure the SMS account, sender and allowed destination format with the operator. Use a short message containing only the information the customer needs.
Put it into practice
Review the recorded provider identifier after submission. Queued or accepted means the provider received the request; delivery requires its later status evidence.
Check before you share
Check the provider dashboard before retrying an uncertain request. Repeated submissions can create duplicate messages and separate charges.
