Do you low signal 1 bar also can hotspot?

Thank you so much of your question, maybe I setting something before, so unable hotspot, maybe now can hotspot, maybe it also show "connected", no more "limited", but I unable go to speed test.
This is don't know hotspot really slow or my area now low signal 1 bar.

The conclusion no like some said, if low signal 1 bar totally unable connect internet, but I still need more time to test it.

This is like not steady, sometime 0 and 1 bar, sometime 2 - 4 bars, but still can connect to internet, just slow speed.
If in phone will suddenly no connection, but very fast back in connection.

You do a speed test? between phone direct connect vs computer connect hotspot?

I unable load the speed test when computer connect hotspot. Perhaps you?
