iPhone 5 LTE - straight to voicemail - Vodacom

[iFoggy]

Hi,

We just got LTE support with the release of 6.1, besides the intermittent no service issue I have noticed that when my phone is on LTE and someone calls me the person calling will go straight to voicemail, if I am on 3G the call will come through.

If I switch off LTE calls will always come in

Been reading into it and it looks like it is a common issue in Singapore, apparently on LTE a voice call cannot come in and the iphone has to first switch down to 3G to receive the call, maybe on the Vodacom side there is an issue.

Is anyone else having this? To test make sure your phone is on LTE, call it and see if it drops down to 3G and rings or do you also go straight to voicemail?

Thanks
