Wondering why people still paying money to provider D to get super long life where provider T is giving 365 days validity for FREE with top up as low as RM10?

I have been loyal to D for 10 years. But recent few years really tak boleh tahan the service they provide.
D have cheaper rates than T? This one I'm not sure cause I totally gave up on D. I just know T charge RM0.20 per min, but with 1 to 1 reload bonus, my actual cost is RM0.10 per min to all local networks. This rate is acceptable to me as a prepaid customer.

However, does cheap rate really matters? I thought people who interest in long validity should be those who seldom makes calls (that's why they always can't use up their talktime credit and hope for a longer validity with their limited top ups).

By the way, D have big share in T. Probably someday when T becomes popular, T will do what D is doing. That time I will have to port out from T and find other alphabet.

Shit. I'm kinda outdated. Thought 365 days validity is the longest but I see other forumers mention about F with LIFETIME VALIDITY!
If got chance I'll get one for my mum. Call rate may not be the cheapest but the lifetime validity really draw my interest.
