LTE handover on calls

[Aharon]

Hi

I am having trouble with the LTE handover on calls. I have the Huawei Mate 7 and it runs LTE perfectly. but calls are going to voicemail.

How do I deal with this?

Thx

Which network? Vodacom?
If you disable LTE, does it make/receive calls in 3G mode?

Edit: See you are on Telkom. They do not have VoLTE yet, according to this site: http://ltemaps.org/home/operator/telkom-8ta

So, what needs to happen when your phone is on LTE, is that your phone must fall back to 3G in order to make/receive calls. This feature is called CSFB. Some phone have issues performing CSFB actions.

Hi, are you saying I need to return the phone?

 

[Aharon]

Sorry, could it be a network issue?

 

[Aharon]

OK, I put in a voda sim and it worked perfectly. Your feedback?

It is probably an issue on the Telkom network.

A workaround is to keep your phone in 3G mode, and only go to LTE/4G if you need to use data for a given time.

Long term solution is to complain to Telkom Mobile and hope that fix it.

Yip that's what I am doing. Still a tad irritating.
