GUS cannot be used
You should not use the GUS Roaming services. It’s extremely slow and most of the time out of services even though I have 4G SIM and do all the instructions of setting all roaming service and register for the Volte.TYTNVN

Been trying to activate the app since yesterday…tried numerous time and kept showing system error, try again later. And eventually pops out a 10 minute waiting time to utilise the app. Can you guys do something about it? If not how can a consumer uses this app to monitor and top up credit as and when required?Show lessfrogman32

Hi Mobifone team,
As a customer who is having high demand of data usage and new to Mobifone network framework. I find that data usage on my plan as MF150 is not sufficient.
I have visited Mobifone shop for support and received very friendly support from local team, yet the service is still not improving.
I am writing this feedback and hope our Mobifone can spend more time to review the product plan for customers. Quote: “ Customers are not happy with product means Company will have unhappy Customers”.
Warm regards and thank you,
HH.Show lessHuynh Hai Trieu
