Roaming APN settings "stuck"

[imNotHappyJan]

Network settings : Optus APN on SGS23 Ultra seems to be stuck searching for Australian Network when it should be searching for local (roaming) network in France? Shouldn't it be pointing to, searching for Orange Network?

Currently in France, have been using Optus daily Roaming pack for in/out 4G/5G calls and texts. 

Bought eSim from Holafly for unlimited mobile Data for duration of trip. 

Has been working fine until 2 nights ago, had mobile update to OS on 26 June, not sure if that is coincidence?

Not specifically that I recall, probably as the issue is not App related? It appears it is a network/ operating system issue that has a glitch, and as it had been working fine for 21+ days and now isn't, it is probably related to system update changes?

Which app cache would you suggest clearing to I help resolve this issue related to a recent inability to connect to roaming network?

Background. Sometime ago when I had a Samsung J8 I had a problem with an app not working after a software update. The ultimate explanation was that when new software is installed some of the old software instructions had remained in the cache and conflicted with the new. To fix it I had to to two things.

In the app itself I had to clear the cache and clear the data. This means losing all the settings and data relating to that app. If, for instance, you cleared the phone app you would lose all your phone number history (unless your phone numbers were synced to your Google account). Sadly I don't know which app is appropriate so we have a problem.

The second app cache I had to clear was in Google Play Services. This on a quick Google is described as
"Google Play Services connects apps to other Google services, like Google Sign In and Google Maps. Google Play Services isn't the same as the Google Play Store app, and is included with Android. Google Play Services doesn't make your battery drain faster or use too much of your mobile data plan.

Keep your device & apps working with Google Play Services

Basically when you restart it resestablishes itself using the updated fixed app. Unfortunately since we don't know which app is faulty this process might not work. Furthermore, stuck in France you might end up with a temporary brick or have to go back to Factory Reset and lose all your data.. I wouldn't risk it but read the above link. To do it go to Settings then Apps, search for Google Play Services (double check you have the right app), open it, find Storage, look for cache empty it and possibly data. Close up and restart. Please please don't blame me if you try it and things go wrong.

Fair enough comment if, as you say, you "have an app not working".

In my situation ALL apps are working fine on wifi and have been working on roaming data, up
until now.

As mentioned above, the issue is in the OS and it's recent inability to point to, connect to, the mobile data provider of both/either Sim/eSim.
Cheers for the input.

I have had several esims with airalo. They can be finicky to get going. It's playing around with it to get it going. It's not Optus. Esims probably broken because of the update to be honest. They aren't fun to get going in the first place. I am next time going to use saily... It's NordVPN s esim. Good luck. Uninstall and reinstall a new esim I say

[imNotHappyJan]

Yes eSim can be tricky, I agree. But similarly, physical holiday Sims too.

The issue is not as simple as soft reboot and or reinstall new esim as NO network data coverage on Optus or Holafly.

Holafly is data only so can't use for GSM calls. Yes I could get a 2nd temp dom but no guarantee it will work either?

It is not important as the cache process I suggested was, as I said, flawed because we hadn't identified what app might need its cache cleared and I had recommended not to proceed. On one point I disagree, not that it matters, you don't know that all apps are working fine as an app stores different data for each sim carf. Furthermore, Google Play Services does handle Google sign-in which is one of the many possibilities.Also, of the OS was broken you shouldn'tbe able to use your esim. There is one more thing you can try. That is to create another Google account. It is reasonably safe to do so, search under Settings, Users. Try not to have the same drtails as your existing Google account as Google will try to link to it, add one day to your date of birth, different phone number if possible (it needs to be real as it might be used for verification). Then login under that user.

I don't think you can do much else until you arrive home. Unfortunately the standard solution is to factory reset so we are unlikely to ever know the source of the problem. Regards.

Contact them through whatsapp maybe their esim need a reset or need a better configuration

[imNotHappyJan]

Contact who? Holafly? Really? Did you read the above? We have deleted the eSim after numerous attempts by Holafly, Optus and Samsung Support to rectify the issue caused by 6.1 update, are you still thinking it is anything other than 6.1 glitch?

[nxmah]

Holafly through whatsapp and I still thinking your phone somehow got network lock thats why act like this
