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