What does message 4UC3 Mean?

[NFtoBC]

In what instance are you hearing or seeing it?

[Tai · Accepted solution]

Hi @Chelle1, the automated recording you're hearing is broken down into 2 parts.

The first digit '4' is the most important, identifying the type of problem. 4 indicates that the problem is coming from the person you're calling, either not accepting calls or being out of service and calls not being allowed by their provider.

The remainder of the message, 'UC3' is a composite number that is used by our technical support teams when troubleshooting.

After the 4UC3 message plays, the automated recording should proceed with the definition of the problem.

• Example:  "4-U-C-3... The client you are trying to reach is temporarily out of service or not equipped for incoming calls. Please check the number and try again."

The person you're calling will have to engage their service provider for assistance.

Thank you for replying Tai. When I send a text to that number, it is sent and received. Does this just mean that the phone was able to receive the text but nothing else?
The message I receive when calling is exactly the one you sent me.

It's odd that a text would go through but not a call, but it's possible that they (or their provider) have something blocked regarding the incoming calls.

My phone tells me the text was received. My question is, is it being stored on their phone? Calling still gets the message 4UC3 or one day 10 V 1? Any help on that? Talked to this person right before this happened. We did not have an issue. I am trying to figure out if it's a service suspension? It never goes to voicemail or even rings.

For your texts, messages would be sent to their device. If you're both iPhone users it may be going through as iMessage which would not be related to the cellular network as those are simply sent through data/Wi-Fi connections.

The 10- message could be a suspension issue as it indicates that calls are barred or cannot be completed. If you'd like to troubleshoot on the TELUS side, feel free to visit telus.com/contact to reach out to the technical support team.

I am a Telus user calling a Telus user. We spoke without any problems a few hours prior to my getting this message when I call.
It doesn't ring at all. Goes right to 4UC1 Or 4UC2/3 Or one day 10 V 1. If I send a text, I can view details which say the text was sent and received. My question is, if service is temporarily off, is my text still being received and stored by their phone? This is confusing me.

I am an android Telus user, the number I am trying is an iPhone Telus user. I will try what you have advised. Thank you!

What happens if you call from a different phone?

Until you speak to the other person, you will not know if the SMS you send has been received, as SMS does not provide delivery confirmation.
