Upgrading to Plus had no effect on hotspot speed.

[ACC]

I had the regular plan which has hotspot speed limited to 5mbps while I was paying 25 dollars a month. 

I upgraded to the Visible Plus plan for the singular and sole purpose of getting 10mbps and am now paying 45 dollars a month. 
However, my data speed for mobile hotspot has stayed at less than 5mbps. I would like to know why this is, if there is any way to fix that and get the speed that I have been paying for, or if I should just leave visible. 

Thank you for you time.

Which speedtest? If by any chance you are using fast.com, video stream throttlng applies since that's a Netflix speed test.

If so, try another speedtest site (e.g. speedtest.net).

Otherwise, contact customer care

Google fiber has me @ 5.7.

Speedtest.net shows 5.57.

Xfinity shows 4.5.

Speed.is rates me at 5.82

and the average speed of a Steam download hovers between 4.7 to 5.2.

Seems I must contact customer care.

I assume those speeds are obtained on the device using the hotspot, not the hotspot device itself.

You need to contact customer service and have your SIM provisioned to fix this issue or get a new SIM.
