Hi,

Just thought this post would benefit some of you IOS users who are thinking of upgrading to IOS18. Updated this morning on iphone 15 pro and 5G Standalone (Ultra) is available and working well. Only thing now is still waiting for Vodafone to add RCS support but hopefully that will follow soon.

It looks like you'll need iOS 18 for 5G Ultra to work on the iPhone 15 @anuraj  I'd recommend that you drop us a message on our social channels so we can check the set up on your account.

Are you able to help with the query I posted on this thread on the 25th (my phone is running iOS 18)?

Thank you. 

I have update to iOS 18 and 5g ultra not stable on iPhone 15plus. 

Hey, @andrewd71.

It sounds like we'd need to take a deeper look into your service and access your account, to determine what's happening with your 5G set-up. Please reach out to us on Social Media using the details here, so that we can help.

I have 5g Ultra on my plan but on my iPhone 15 Pro Max settings under Voice and Data the 5g Standalone toggle is greyed out. The message displayed says "Your current SIM does not support 5g Standalone. Contact your network provider for more information.." Can anyone clarify this?

I think it's because Vodafone doesn't officially support iphone 15 Series yet only 16 series. People have gotten SA working on 15 but its not as stable as on 16 series

Are you using iPhone 16 series?

Does your display showing 5g u/w or 5g plus in front of the screen ?

I'm using iPhone 16 Pro Max.
It doesn't show any different on any device. If you download Nperf it will show you. 5G SA is Ultra. 

Thank you for your information. Is it better to leave 5G on or 5G auto on setting mode ?

Hey @anuraj, it would be better to leave it on auto, so the device will switch automatically to the best signal available in the area to help give you a more stable connection.
