I have an unopened voicemail from this afternoon on my phone (iphone 5s) and when I pushed the usual voicemail button it made the call but gave me an error message (6ut1 and 6ut2) saying that the number was out of service. How is this possible if it is Koodos system? I need to access the voicemail and am having no luck. Voicemail is a part of my plan and I have accessed it before with no issues. Any thoughts? Anyone having a similar issue?
