Smarty sim in iphone 11 does not work

Hi StephenB_584576 👋
When you say that you SMARTY SIM won't work.... do you mean at all or just for calls/texts/data?
When 'unlocked' phones are discussed this covers ONLY the connection to MNO! It DOESN'T mean that even though you are able to connect to ALL networks (with it being 'unlocked') you will get complete use of all available capabilities of the phone.
ALL phones software updates are controlled by the 'original' seller fo the phone and even though you think you are getting all updates you aren't!
I made a post with regards to this.......
