maxis prepaid user here. since maxis now so rahmah rm40 200gb/48mbps and rm55 200gb/uncapped(got 50-110mbps)
but at some Lrt station terus no line. i use samsung a30 4g phone in pj/kl.

last year tested celcomdigi and yes prepaid but tested many times got 1-3mbps wtf.

last week took 2nd prepaid tunetalk at rm50 350gb. the speed is funny 1st got 50-60mbps(still on my 4g phone) then after 1 hour 3-5mbps. then 30mbps. but good because in Lrt got line

its funny cuz last year use celcomdigi and yes the internet was worst. and tunetalk and yes is under celcom but tunetalk speed so better.
