### 1/5 — Zero1 apps not able to see the data plan

*2022-03-01, version 1.1.2*

Hi, SIM card gave activated but apps not able to see the data plan. Please advice. Thanks.

### 1/5 — Login issue

*2021-12-13, version 1.1.1*

Already I had sim card, but you ask email id to buy plan again. Why not login via SIM card  with OTP option is not available ?

### 1/5 — It says no mobile line registered

*2021-08-20, version 1.0*

It says no mobile line registered even though I could clearly see my bills within this app. What’s going on…

## Most critical reviews (10 lowest-rated)

### 1/5 — Data is too laggy

*2026-01-24, version 1.6.14*

Totally cannot access in MRT, very slow speed data at home. No point

### 1/5 — Beware of hidden t&c

*2026-01-22, version 1.6.14*

They didn’t mention their T&C in the app, web or ads that the international roaming will cost non pr or non sg residents $500 for deposit. And even the local network is worse than my previous one.

### 1/5 — App doesn’t let me view usage or others

*2025-02-12, version 1.6.10*

Only after I subscribed the app stopped working. Is that supposed to be intentional?

### 1/5 — Hopeless login

*2025-02-09, version 1.6.10*

What nonsense! Need login every time you open the app and almost every 2 mins. Logs you out. Sometimes need login again for different sections eve though already logged in.

### 1/5 — Improvement request

*2025-01-04, version 1.6.10*

Please make it so we dont have to keep relogin to check usage

### 1/5 — Useless

*2024-10-03, version 1.6.7*

With the previous version I couldn’t add a new card. With the latest v1.6.7 I can’t check usage… the helpdesk always suggest to use the web portal, so I deinstalled this app and just bookmarked the web portal.

### 1/5 — Can’t login to apps

*2024-03-10, version 1.6.4*

I tried login to app to subscribe to oversea roaming but I can’t login at all , going oversea with no roaming…. Omfg

### 1/5 — Unable to login

*2024-03-09, version 1.6.4*

When trying to login, it displays ‘Expired/unauthorised token! You are not authorised to access this location.’

### 1/5 — Unable to see usage

*2023-06-13, version 1.6.0*

Login prompt no longer appears on startup, usage screens are blank

### 1/5 — Keeps logging out

*2022-12-17, version 1.5.0*

Keeps logging out

## Most praised reviews (5 highest-rated)

### 5/5 — Great service

*2025-12-14, version 1.6.14*

Giving money for addons takes a few business days. Customers are not allowed to buy addons when overseas.

### 5/5 — Simple Interface. Can improve further.

*2025-01-05, version 1.6.10*

Easy and simple to use. Can improve further by allowing user with multiple lines to rename the number with user names as well.

### 5/5 — Takes too long to load the app.

*2023-11-05, version 1.6.2*

Please fix the app loading as fast as possible. Every time needs to close the app and then relogin to check all the functionality.

### 3/5 — Keep getting logged out

*2022-04-05, version 1.4.0*

Able to check usage but keep getting logged out.

### 2/5 — Display Bug

*2022-02-26, version 1.1.2*

When I use the Zero1 mobile application to check my data usage, I am unable to do so as it just shows me a grey box. Please fix it asap.
