Well it really depends. Usually TM will only charge for cabling insider the house not outside. I have a case where the pole was too far away from house, customer was given an estimation of RM1xxx+ . Brought the issue up to TM, showed some documentations and magic happened. Whole job was done and customer didnt even pay a single dollar.
Bro this is unifi discussion thread la. Furthermore not every where got maxis. Maxis coverage is so so limited so no point proposing it here.
