some non-scientific non-data daily experience.
for my simple needs, eight 4G/5G are adequate. Simba is my backup.
eight on value 5G, Simba on Superroam 12
last week came back to SG.
just before immigration, remembered not yet filled in SGAC.
open app, say need to update. damn.
on eight, download app update is slow like <unmentionable>. Estimated 1hour.
cancelled and used Simba.
Surprise! in daily life, i only get 4G/4G+. This time, 5G, download in 6sec.
over the past week, even though i still don't get Simba 5G outside of say, airport, it feels faster and snappier than eight.
(I didn't bother to do speed tests)
Earlier, passed by the "mobile coverage bermuda triangle". All 4 telcos struggle at 1 bar or no coverage at all.
eight went to no signal (as expected, zero bar). Youtube just stalled, as expected.
Surprise. Simba went to 5G at 3 bar. Youtube resumed streaming.
Walking back underground.
both eight and simba fell back to B8 (900MHz).
Simba provisioned at 10MHz bandwidth
eight provisioned at 5MHz <<<---- this may explain the slower/throttled speed lately. Used to be 20MHz.
Dunno if this lower bandwidth applies only to eight, or to SH in general.
