No iPhone XS Max (yet) but if you've to do manual configuration, if I remember correctly...
There's an "EAP Method" drop-down list, choose the option "SIM". Thus, EAP Method = SIM. Then it should connect already.
Hope the above helps somewhat. Have done this with an Android as well as iPhone before.
Any bro having problem connecting to connecting to Singtel WIFI using iPhone XS Max?
When I try to connect, it asked me for username and password.
No problem previously when I connect using my iPhone X. It just connect automatically.
arm there is no option to choose authentication method. the moment i tap on singtel wifi or SingTel wifi, it prompted me for user name and password. no other option available.
I believe the new iOS 12 has tweaked the user interface a bit.
I have reached out to singtel tech support just now, there were 3 actions done.
1) singtel reset my line totally, clearing singtel wifi records of my previous handset
2) advise me that should my next new iOS device giving me the same issue, to reset network settings via settings page.
3) to remove and re-insert the singtel sim card in the presence of singtel wifi coverage. (rationale is that singtel telco network profile will be reapplied and by default, iOS will turn on wifi and singtel wifi will automatically be registered, according to the agent).
I have yet to test out after my singtel wifi account got reset.
However, the above do not apply to android user, cos android can choose EAP SIM.
