Hi all,

I have a mate whose outgoing calls on Spark is dropping as soon as it gets connected.

However, incoming calls, TXTs and mobile internet are not affected.

He has tried rebooting, and resetting network settings to no avail.

Located in Auckland, but I don’t think it would be a network issue as I am also on Spark/Skinny and have no issues.

Any ideas?

Yup quite likely. We were both at work.

Sadly you can't lock the iPhone 12(and likely the iPhone 13) to 3G only. OP's mate might be able to disable VoLTE within settings(if this can be done on Spark carrier bundle, I know it can be done on 2d and voda).

That is crazy now I know why I will never own a iPhone

@MaxineN - You can’t disable 4G on the Vodafone carrier bundle either.
It’s 5G on, 5G auto or 4G.

The 2degrees bundle lets you lock onto 2G, 3G and 4G, of course you lose the VoLTE option if you move off 4G.

I suspect the settings will change once they get their VoLTE approval and/or 5G settings

Oh yeah knew that but at least you could disable VoLTE still to rule out VoLTE being weird.

Try the latest iOS update (15.1.1, out today), its sole purpose is to "improve call drop performance on iPhone 12 and 13 models".

Thank you guys for all the suggestion. It seems to have fixed itself overnight. Not sure what triggered it.
