It has been more than 20 years since I hold my mobile number and line with M1. Over the past few months, I have been noticing that my M1 mobile reception has been weak in quite a number of places in Singapore. And, there really isn’t any benefit for a loyal customer like me, who has been with them for so long. However, I still believe that M1’s customer service is the best among all telcos in Singapore. So, over the past week, I made the decision to finally make the change to Singtel, together with all 3 of my family’s line who are under my name. I also used the chance to upgrade to the latest iPhone 13 Pro Max. I have been using iPhone 11 Pro Max over the past 2 years and migrating my phone’s content, wasn’t as smooth as I expected. From the past 2 days of usage, noticed the below needed to be re-setup.

Google 2FA authenticator needed a manual export and import from previous phone
All banking soft tokens need to be migrated. For OCBC, it was particularly troublesome. As it needs the pin of a credit card, which I do not remember.
