If your customer's phone is turned off, the message will fail to get through to their phone. Sometimes if it's super busy, a server might stop their service entirely. Why is my message stuck on SENT?Īlthough we use an adaptive routing system, busy periods can cause congestion for mobile networks. Losing internet connection during this time will cause the text message to fail to reach the intended phone user and may result in a 'failed to send' notification. We aim to equip you with the tools to spot this and rectify it.Īt this stage, your text message has not reached the customer yet but has reached the server that delivers it to the customer. This is where most businesses breathe a sigh of relief and continue with their day, confident that their customer has received the notification about their taxi arriving, only to find out later that the message “failed to send” and caused untold grief to the customer. 'Sent' gives the impression of smooth sailing but the journey of your SMS message to your customer's device has just begun. SENT = Message has been submitted to the cellular network or carrier for delivery.
