5G and VoLTE (4G Calling)

[BigDaddyUK]

Hi there.

Question is 4G Calling (VoLTE) service supported by O2 with 5G signal/connection? Or only with 4G! I mean with 4G or 4G+ this works, does it work the same with 5G?

Yes it will work with 5G. As long as you have a 5G capable phone and sim and are in a 5G area.

If there are any issues, it would revert to 4G.

Edited to add, this is such a good question, I'll tag @Chris_K to the thread. It will be interesting to see what he has to say about it.

Thanks. Tag @Chris_K  as well

VoLTE does work over 5G and you should be able to use it with a 5G handset.

Vo5G will also use VoLTE as a handoff and uses the same infrastructure, it will depend on networks to support Vo5G

However it is dependent on the handset.

@BigDaddyUK 5G sims are backwards compatible, so there should be no problem. Take a look here:

It will be years before the 5G network is fully operational (some places don't have 4G yet) so VoLTE will be around for some time to come.
