iPhone Mail CAN'T Send Out Email with new SIM card
Hi all.
I just changed to a new telco/mobile service provider. Using mobile data, no issues with using apps like Safari, Facebook etc. I can send out emails with my Gmail account (using Mail app) and company email (using Outlook app)
EXCEPT My very own iCloud email account. Cannot send out email, will get this message after attempting to send for a while. (see pic)
Wifi wise no issues sending out emails.
So I "suspect" has something to with the new SIM card new provider.
Any idea where I can start to fix this?
Many thanks.
