I have just flown to the US and forgot to set up my roaming in the "going abroad" SIM applications menu. Now when I try to access the SIM applications menu it is flickering constantly and when the SIM applications menu option does pop up nothing works (link to video that shows issue, its hard to describe: https://imgur.com/a/4B49ZEy).

I am on an iPhone 8+ and currently on IOS 14.5.1 (I just updated ios version today to see if that would fix the issue).

I have also tried to set the network manually from the IOS settings but that also did not allow me to turn of automatic network selection.

Also when the settings do flicker sometimes event.proximus.be pops up in the APN for mms but the data apn is still 48months.liffeytelecom.com.

Thanks and please let me know if you need more information!
