with official warranty
tplink x50 5g
tplink nx510v (beware telco set)
tplink nx200
without official warranty, so buy at your own risk
zyxel nr5103e with three logo
olax g5018
gteniq cp570 iq02x55
nokia fastmile 3
arcadyan aw1000 with qwrt firmware
zyxel nr5103e v2
zlt x25 pro
big boys like zte and huawei hard to differentiate from exterior look whether it is telco set or not, some with and some without telco logo printed on outside.
for normal user, i recommend tplink if u don't want to have risk.
if you want to go with risk, olax g5018 is a good choice due to its user friendly interface. gteniq cp570 also similar, you can go youtube watch its setting first before making decision.
if u want endless setting to play with, arcadyan aw1000 with qwrt firmware will be your choice.
if u want cheap, nokia fastmile 3. (if you are sure your area with good 5G signal because it can't lock band)
remember always get mediatek t750/t830, qualcomm x55/x62/x65/ (or above) 5g chipset based modem.
also beware don't fall into seller's trap like:
1. locked telco set
2. mention qualcomm chipset (for wifi only) without mention unisoc 5g modem chipset.
@BOTAK_WAI Thank you very much for your detail update of the info. Very useful for me. For the tp link x50 5g, I think I have read some thread saying that are some issues of setting or connection ? But I am not able to find them now. Anyway, thanks again.
