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)
