I'm not sure about Samsung but I've noticed on my Xiaomi, if you turn off the phone screen and put it into sleep, it likes to drop from 5G down to 4G
My guess it is to save battery

check in settings I suppose

You did not buy prepaid to test out before going postpaid?

Can try to cancel but probably need to pay 1 month advance first before terminating the line.
You will overpay them, after 1 month of termination they will send you the final bill on how much you overpaid them (negative balance) and you will need to call hotline to claim from them.

or your 5G router problem.

What 5G modem are you using, some cheaper ones in the market not so good.

Uhome 5G sim is not meant for use with mobile devices (hp)  iirc , u need to use it with a compatible 5G router

Fibre internet providers now sweating and don't have a clue why their revenues are now slowly reducing?

For the price you're paying with no contracts you still want to return to 100Mbps fibre?

Can i purchase the umobile simcard from 7E and buy the uhome 5G package?

hi sifus,

just took umobile 5g together with the ZTE MC888s router black color(contract for 2 years) yesterday.

so far been testing almost a day, and the nearest 5G tower is just behind my house, about ~100m, direct LoS.

but average speedtest i get is <150Mbps DL, 20Mbps UL at my parents' house in Klang area.

i checked the speedtest pattern,

afternoon - got ~130Mbps
evening - ~25Mbps
midnight - ~35Mbps

latency wise, ~30-50ms. 

this is very unacceptable. But i could easily get ~500Mbps at my home in Jitra kedah or Penang though via ZTE MU5120 5G portable router ( i have another U5G simcard).  

all settings are by default, except i changed the wifi password of course.
so I was thinking to buy another 5G router on shopee.

so Zyxel 3UK NR5103E v2 comes to mind. This one using Qualcomm or Mediatek chip ya?
Saw TPLink X50 5G but the price is kinda steep. 

Didn't want to terminate to pay the penalty obviously. So i just continue using this package like normal.

i shall make the ZTE MC888s as a spare router in case i could use this better at other places using my another U5G simcard.

Probably it’s the router issue, I also have U Home 5G and never had issue with the connection, I bought my own router. Always fast speed. The bundled router is problematic based on the feedback here.

Yeah competition from peer users.

Compare the equivalent data when using other providers, that will tell us more information if the congestion comes from where.

Haha I am already confused.

Were you talking about maxis 5G giving you 5mbps or you were talking about Umobile ?
