unable to connect roaming when i was in Japan inspite of having 6GB international roaming

Completely Unprofessional Service

2025-03-07

by 9QingYi

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.

Too Many Bugs, Inconsistent Even When in SG

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)

Buggy app

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
