Giga is okay for me so far. The hotspot service used for streaming is way better than Simba no doubt there's some buffering but still watchable.
But then, my current plan now is $20 for 400GB with 8G Roaming too overkill as I only used 100 plus G per month looking at my past few months of usage. And worst is my data was so much because of rollover extra data
So I had decided to migrate to 8 mobile $8 plan with 228GB Data, 10G APAC Roaming , 2G Int Roaming.
I believe reception should be the same since both are using StarHub Network.
Just check that my number can be ported over to 8 Mobile from my current Giga.
My current Giga plan is 5G but then I always received 4G so maybe wait for a longer period then consider 5G.
