I just received a call from this number  27275828 claiming giving free 3 months trial no upfront, no contract to sign or anything for 10mb and if don't like can cancel anytime.

Sounds too good to be true. Anyone got this offer and what's the catch?

I call it Unlimited 4G RM18 (monthly) that if you have know-how to setup your own server (Mine was done by a taikor here <--Great Guy).

If you want, be prepare to pay him [Setup Fee aka Rm40 or more which come with "software"] after you sign up with Server Hosting directly.
He will kautim for you that if you wanna your own private server.
Any maintanance on your Server, he also can do at a nominal fee.

if you wanna easy way, can rent aka rm20 or lower monthly from many Seller here or at FB.
You will get necessary tools to run it, almost like plug and play.
Eversince Celcom GhostBUSTING mode, it seem it will be wishful thinking that "Ghost mode" will stick forever to SIM.
As you can see, eversince Celcom PPU....almost all Ghost vanished.

Oh ya,
There is a condition if you wanna venture to this
As usual no warranty ya as i found out yesterday, any SIM also can get "blocked" also.
Advisable to get a standby SIM so that you can troubleshoot easily.

Good if your area got 4G and if you currently have 4G and using legit plan and get good speed.
Then this method will also have same speed as well without buying any monthly plan but need active validity aka 1 year validity. Credit below 50 cents is the best.

Since it can be use for PC only,
that is why i can it Unifi but without buying any monthly plan with right criteria.

Yes, it can be "mind blogging" trying to understand it but rewards is indeed blessing.

This is what i am getting now.
