Where to buy a similar Vietnam SIM card aimed for locals/expats (not for tourists) in HCMC? [duplicate]

I live in Thailand and use a dual SIM smartphone currently containing only one SIM card which is my local prepaid Thailand SIM card.

I already visited Vietnam twice; each time for a few days;
In both cases I bought a prepaid SIM card inside an airport;
Both SIM cards I bought were of Mobifone and aimed for tourists (for "one month") usage.

Both aforementioned SIM cards contained similar specification:

1) Web package

4GB web bandwidth

4MB web download speed

2) Telephony package

Unlimited incoming local phone calls

Unlimited incoming global phone calls

Unlimited outgoing local phone calls

Some possibility for outgoing global phone calls

3) SMS package

Unlimited incoming local SMSs

Unlimited incoming global SMSs

Unlimited outgoing local SMSs

Some possibility for outgoing global SMSs

_{By unlimited incoming global SMSs I could keep getting SMSs From Thailand based on my Thai phone number → from both my Thai cellular operator and Thai bank company (often based on their applications) and thus both top up my Thai prepaid SIM card and control my Thai bank account overseas.}

My questions

I need a SIM card for six months or one year with a similar specification but with;
Unlimited internet bandwidth for fair/plausible use (non commercial use).

I believe such SIM card will only be sold outside a Vietnam airport.
