Even if u chosed digi as backup esim, they're already merging with celcom so in a year or two they'll also be sharing same tower network. Currently your only choice for cheap esim is digi prepaid, but soon your only choice will be maxis after celcomdigi merger completed.

Instead of doing that why not just just use hotlink physical sim with celcom esim? Or just use digi prepaid esim, the merger complete and tower sharing would still be long away from now. I would never use the unknown mvno. Legit haven't even heard of that name before and legit i thought maxis doesn't have any mvno. An unknown company with literally zero advertising is a nope lol.

You got a valid point there.
Yes hopefully that is the case.

By the way, i just discovered yet another MVNO telco that rides on MAXIS network. It’s a prepaid but the package is quite interesting:

RM170 per year - 60GB
5gb/month

RM420 per year - 180GB
15gb/month

Ansar Mobile, which was operating on RedTONE company

But the downside is, they only offer physical nano sim.

So perhaps i should convert my primary celcom to esim, and Ansar mobile secondary on physical nano sim. 

What do you guys think?

Yoodoo is going off soon isn't? or it will continue to stay?

Also, i am quite new in esim tech.
I understood that we can only use either one of the cellular data per 1 sim (physical or esim). cannot run BOTH at the same time?

so considering this scenario:

let say i have exhausted my primary celcom data, and i would like to switch to secondary maxis postpaid esim to use the data, how should i do it? Do i need to manually select the cellular option to choose on Secondary in settings?
or iphone esim can have some sort of smart cellular data management auto switchover function?
Say it will auto switch to maxis data if i can't get reception on my celcom?
also, using dual nano + esim will definitely drains the iphone faster because connecting to two networks will be more taxing than one yes?
