I just ported over to Z-One 4G at $10. Was told that for users under this plan , there is no option to top up your data nor purchasing other add on services liked data roaming. What is listed under the plan is what you will get. But for $10 and free 2GB data roaming for 12 months use in Malaysia, i think it's valued for money (For users who go to JB weekly). Just hope the GPS and reception is much better than GIGA, as i always happen to get bad GPS connection via GIGA network.
Question: Am i right to say all NVMO don't use voLTE?
