SMS sending failed – this could be the reason

If your smartphone displays the message “Send failed” when sending an SMS, this may be due to your mobile phone, your provider or the recipient. We’ll show you how to solve the problem.

SMS: Sending failed – this could be the reason

The SMS is still popular. It doesn’t matter which mobile phone you have or which version is installed. Even WLAN is not necessary, because SMS are sent on the telephone network. If sending fails, this can have different reasons.

• In football stadiums, on New Year’s Eve or at other large events, the network can quickly fail due to congestion. You will then have reception, but neither the data network nor calls and SMS will work.

• If the transmission problems occur abroad, the problem is usually roaming. Messages are routed through different networks and certain information is lost or unreadable.

SMS: Send failed – possible solutions

An unsent SMS is no reason to panic, because the Short Message Service – which means SMS spelt out – is very reliable. Most of the time, simple remedies are enough:

• Restart: In most cases, the problem can be solved by restarting your mobile phone. This will completely turn off the system and re-unlock your SIM card.

• Number: Also check the authenticity of the number. If the area code is wrong, the SMS cannot be sent.

• Time: If the time on your mobile phone is completely wrong, this can also lead to complications when sending.

• Confirmation: You can check whether a message is really being sent by using a delivery report. We will show you how this works in this practical tip.

• SIM card: If you have a smartphone with dual SIM, try the other slot. Your phone may not recognise the card because you put it in the “second” slot. If your smartphone still does not recognise the SIM card, try it in another smartphone.

• Provider: Finally, the only thing that helps is to call your provider.
