I did port out my numbers to OneXOX.
Telcos are greedy, especially YES in this case. They want your money and won't allow you to port out.
BUT you have the power, consumer power. Escalate this matter to MCMC/SKMM. My case solve quite fast!
No need to upgrade to postpaid and tie up on their stupid contract. I able to upgrade to their new postpaid plan and port out few days later.
Teach this YES a lesson, I definitely won't come back to this useless telco.

for huddle u need to go for ID. normally RM30 u only get 4gb.

He need teethering thus kofem 4g plan is not able to teether

Are you referring to YES LTE or the YES ID i.e WIMAX Broadband?
