FYI...paid a visit to the SIMBA's shop.
If 2 mobile numbers were to port in, both will appear as separate accounts although both will be under my name/email.
Each will have their own login account/app.
However the one & same app is only needed within my phone, but I need to logout of one & login to the other if I want to view that account.
... to login into my partner's account/app in my phone, a SMS OTP will be sent to her & I need to input into the app in my phone.
And for each mobile I'll need to apply separately for port in - no single entry page for both.
He told me to start process on 11th July since my contract ends on 10th July
