Thanks for your reply.
I understand that. When I travelled, I usually get tourist sims, so for all my past telcos, I only keep the pay as you roam (no monthly subscription to pay), in case I need it for calls while overseas and I am fine to pay the higher charges if needed as compared to paying monthly $10+ for an autoroam plan with lower usage charges.
I am the type that just unsubscribe anything unnecessary even if it is free for x months.
So now my Singtel plan came with 1 gb Asia roaming, I initially don't know what is the difference between pay as you roam and auto subscribe ready roam(no monthly subscriptions to pay) in my plan and whether are both required to use the 1gb Asia roaming or not thus my earlier query.
After reading through their website, understand the auto subscribe ready roam is merely a service which will help to auto subscribe to a ready roam data plan when detected you are overseas to prevent high data roaming costs. So I guessed no issue to keep both.
Intel Singtel auto roaming package is very expensive 1GB only.
They position themselves as a high class/premium bouquet.
They constantly upgrade their equipment to younger, bolder, some say the base station is better looking than other "local" providers.
Of course they are facing intense competition due to the influx of "foreign" talent competitor they are able to operate in more "lean" manner.
Don't rent expensive place to provide their customer service, renting in the heartlands allows you for a wider range, in the end what all the customer experience the same when you insert the sim card into the phone.
Simplify billing process, to reduce time opportunity cost over bargaining over prices, offer simple menu aka "一条龙".
And of course the ability to procure non angmoh equipment, cheaper, better, faster.
Since you like to auto roam may i suggest you look at Simba, they offer the best package for roam-er like you.
