SH and M1 ain't the best in sg.
Singtel is best in sg.
SH some area ok only. Overall better than M1. M1 is the worst in sg. Used them for 2 year and banned them for life. Even worst than Simba 7 years ago.
ST engineering amk also don't have signal. For that 2 years. I cannnot even use phone during working. Fml
yeah. personally experience with ST, SH, M1, TPG (before Simba). This is for 4G. Ever since MVNOs started in lion city, i had shifted to MVNOs and i stick to 4G plans only becos cheapest.
indeed m1, TPG are not to my satisfaction.
SH not too bad but do have some blind spots.
ST is overall good even with very minor blind spots.
Seems like even roaming experience with different telcos in overseas also the experience varies even roam to the same roaming partners. the funny thing is also that the 4G/5G on the roaming partners are the same but experience can be totally different.
So not sure if this is the same situation while 5G infra is actually shared among all telcos but experience can be the same.
