### 3/5 — Great service, Horrid app

*2025-01-19, version 4.9*

The app is very slow to load and clunky to navigate. The service is very good value though- highly recommend

### 1/5 — Can’t use at all

*2025-01-05, version 4.8*

It keep telling me to update new version but there is nothing for me to update and I can’t use the app at all!

### 1/5 — Buggy app

*2024-12-17*

If you don’t update the app before travelling you can be in trouble. Arriving in Australia it said I needed to update the app before using but you can only update the app in Singapore. So I am stuck with no mobile service until I get back

### 1/5 — A bad app

*2024-11-19, version 4.8*

Cannot even cancel the line keeps showing error. Live chat says need to wait 30 mins. Been waiting for more than 1 hour. Really bad service overall. Avoid this service if you like a peace of mind.

### 1/5 — Doesn't work

*2024-10-28, version 4.8*

Doesn't work still say maintenance. Oh well on to another app to pay for data.

### 3/5 — Bad Data Roaming & Subscription

*2024-02-22, version 4.2*

This plan is both good and affordable for use in Singapore. However, one major drawback is that I cannot resubscribe to a cheaper promotional plan. Additionally, I would recommend others to purchase an overseas SIM card for data usage instead of relying on the gigaRoam plan. When I used it in Hanoi, I experienced frequent disconnections, with approximately 90% of the time being disconnected.

### 1/5 — Too Many Bugs, Inconsistent Even When in SG

*2023-07-21, version 3.0*

Giga advertised cheap roaming in ASEAN to attract subscribers then seems to have focused entirely on SG operations. When traveling to Indonesia, I sometimes cannot even open the app—it just states “loading.” In Malaysia, my pre-bought roaming package did not activate. The app is suitable in SG, but even in SG, speeds can vary significantly. I am giving a low rating because customer service has responded to me using pre-formed, copy-and-paste messages that do not not indicate an ability to identify their issues. (July 2023)

### 2/5 — It’s radio silence in Giga land

*2023-05-17, version 2.2*

I have bought their roaming data fir JB but I m not able to use all that data as you must connect to Thia giga! network only. There is barely any signal here in Gp. I tried to contact the giga! network, but all you get is an auto bot which gives you the same instruction over and over again. Don’t waste your money.

### 1/5 — IPhone 6 support?

*2023-03-11, version 2.2*

Does this new app version kill iPhone 6 support?

### 1/5 — Completely Unprofessional Service

*2023-01-06, version 1.69*

Probably the worst experience I’ve ever had. I was told that my SIM card would be delivered once the driver has called me within a specific timeframe and sees a form of ID to verify my identity. Not only did the driver not call at all, but he just handed it off to someone who happened to live in the same gilding as me without any verification. When I received notification that it arrived, I had no idea where it went. I spent almost two hours waiting for customer support to address it. The driver then called my American number instead of the local one I provided to avoid international call charges. This change was done earlier that day (which another 2 hours because the app wouldn’t let me do it myself) and was assured by the agent yet clearly it did not work. Luckily I was able to find my package, but I’m horrified that the driver just gave it away to someone else. giga! also never apologized or even acknowledged the whole ordeal. Once I let them know I had the SIM card, there was absolutely no response. The entire exchange was done through Instagram DMs so I can see that my messages were seen and just ignored. I’m appalled and shocked by the unprofessionalism that giga! exhibited.
