Sim Application option missing from Settings

Hi,

Has the Sim Application option been removed from Settings/Mobile Data during iOS updates in the last 3 months or so? I noticed that it was no longer there yesterday, I updated to iOS 15.7.3 which was available just in case it made a difference but it’s still not shown. Using the Sim Application to change the selection mode from Automatic to Manual/International ( and back to Manual/National when back in the UK) is necessary to obtain a network connection when roaming with Virgin Mobile. My wife (iPhone 8 also Virgin sim) and I (iPhone 7) had to make these changes to obtain service in Majorca in October last year, however the option is now missing from both phones. Virgin customer forum team’s response was to check an iPhone, agree that it wasn’t there and suggest using Network Selection instead to choose a carrier when roaming, given their track record I don’t trust their solution.

Thanks
