I also use Hello (mainly keep no.). I have all 4 brands SIM CMHK (K60, main), 3 (self-made annual), CSL (Hello), SMT (annual SIM + $48 SIM) <- will not use anymore after expiry & use up present stock (2 $48 SIMS). I already cut home internet & use K60 instead. Total expenses for mobile + home internet / mon is $5x only. Later K60 will have more expense as MNP is difficult than before but still $5x if cut SMT
