on Eight trial sim card dropping to 3G+ data. Now cannot see in Aug what will happen of 3G shutdown, what 4G connection dropped to?
then i suggest you not to port to eight. My experience with eight so far for a week (on $8/plan), it's super slow and laggy on MRT, EWL NEL. I don't experience as much laggings as compared to Simba.
I don't see it going to improve future, Singtel Starhub M1 are all focusing on making 5G better, and transiting people using 3G to 4G, will make 4G even more congested.
Starhub will close it's 3G only from November, once shut down, there won't be any fall back to 3G. So it's time they start to move people to 5G.
