for my case . i know what i need or how many Data/call i use , so can save a lot.
last time using YES rm15 for 10GB data using for 1month , call rate also cheap 1min 9cent .
tben i found that i not use that much data , just using 1GB or less , so find Hotlink Pantas , it can buy data can use for 365day , +can buy 365day validation , so RM10 buy 5GB can use around 3~4month . calculate 1year then monthly average using RM5,
but the call for hotlink pantas also weak , 1min 30sec , so i search for call case , found unifi Bebas (no more this plan) , very good for call purpose cause i not chat more for call , just call for remind (working need) , my unifi bebas line register at Dec2022 , simcard RM10 , topup RM10 to buy RM7-60min , use until today Jun2024 (only use RM20 total , still left 26min)

U need to chg to this prepaid for u n ur atok
Postpaid got tax, prepaid no tax



For new hp buy redmi note 13 / realme c63
For unifi kenot do anything unless u buy sooka from shopee

Wow, looks good.

What means 40GB but 30GB hotspot? 10GB reserved for phone only ka?

For prepaid, how to make sure it doesnt expire each month? Because I afraid forgot to reload.

30gb can hotspot frm 40gb quota
If dont hotspot then use all 40gb quota

U need to set monthly alarm reminder in ur hp to reload
Set to 25 days. Dont set monthly coz this prepaid folo 30 days not monthly

If accidentally expired or credit empty, they won't just delete my number right?

I can just reload and reactivate online?

Also, credit empty still can receive incoming calls? Make whatsapp calls over wifi?

Yes reload and activate. But got grace period
Yes can receive call
Yes can Whatsapp call with wifi.


Another alternative
Get astro broadband. 100mbps plus astro for rm140. For grandpa

For mobile, stick to Digi rm25 x2
Total cost 190

Phone buy separately. Now rm600 can get decent phone

Well if the coverage is ok your grandpa could consider the new yes plan
