Significant delay in voice calling - both on wifi and without.

Hi everyone,

I am quite new to Smarty and have an issue with voice calling - Calls connect with no problem but there is a significant delay in the other person hearing me. Sometimes this delay is such that I have to abandon the call. It seems to be worse when using WiFi calling. I’m on iPhone 12.

Any thoughts?

I have very good WiFi Calling on my iPhone 13 @PhilRig

I'm running iOS 16.7.1 - what iOS is running on your iPhone 12?


I’m on 17.0.3 so bang up to date. I’ve tried resetting everything and clearing cache etc so hopefully that will help.

@PhilRig Any chance that you could try the sim in another phone to see if it is replicated? This would rule out a problem with the handset.

I’m having this issue too on an iPhone 15 Pro, with full 5G signal or using WiFi calling. Brand new SIM.

im really anxious for a fix. I’ve tried logging a support call via chat, the staff didn’t really seem to understand and just closed the ticket after a few weeks.

@BrianMcBriany  As I said earlier to the OP, have you tried the sim in another phone?
