I also looking to port over to VIVIFY next month... but after looking at my needs, wife + me + parents, we all use less than 3GB a month given that my parents and wife always at home... so buying the basic $8.80 plan seems cheaper cos we don't need much data...
I was on myrepulic. Always got dead spots where I need to use , so quite Sian. Steangely, with circles life which is using M1, the dead spots don't exist.
Vivifi not bad la. I swap over, and one of my SIM card like cannot activate. After 2 or 3 email all replied within a day, they courier me a replacement SIM at no extra fee.
No more dead spots also.
Actually I feel zero1 is the best, almost Singtel like standard. Only problem is , they reply email like FEW MONTHS down the road. Had some dodegy charges, email them no reply, port out liao, then few months later email me say no issues.
If their customer service half of vivifi standard , can use zero 1
