I am using iPhone 12 pro and switched to Simba's eSIM yesterday. Was previously using their physical SIM with no issues. After switching, I realised iMessage and Facetime was not able to activate with my mobile number. It can activate with my Apple ID email but I do not use it as a primary ID for iMessage/Facetime nor do I want to.
Did some checks on my phone and found out the following:
- The "My Number" field in my iPhone cannot be edited (Settings -> Phone -> My Number)
- My mobile number is not shown under Simba eSIM entry on the eSIM list (Settings -> Mobile Service -> SIMs)
- The "My Number" field is blank in the Simba eSIM details (Settings -> Mobile Service -> SIMs -> "Primary" eSIM)
- There is a message under my registered mobile number in iCloud saying it is unavailable for iMessage and Facetime. Tapping on the "i" icon at the side will show more details i.e. This Phone Number Cannot Be Used by iMessage and Facetime. You must have a SIM assoicated with an Apple device for <my mobile number> to be used for iMessage and Facetime (Settings -> Apple ID -> Sign in & security -> Email & Phone Numbers)
I have tried turning off and on iMessage/Facetime multiple times but the spinning wheel does not disappear next to the eSIM label even after 1 night. Apple's help page on being unable to sign in to iMessage/Facetime says "If iMessage is on and a spinning gear appears next to your phone number, your device automatically attempts to verify your phone number. There is no need to repeatedly turn iMessage off and on.".
I have also tried several times to on/off the iPhone as well as do the reset with the volume buttons and holding down the power button until the Apple logo reappears.
From my research, it seems that for whatever reason, my mobile number is not associated with the eSIM as some deeper level. I can make and receive calls, get online, send and receive SMSs etc. with no problems.
I have contacted Simba via their webform for help but have yet to receive any reply yet.
Anyone can shed light on my issue?
