hotspot on Iphone 13 - download speed is very fast but upload speed is 0

Hello @crynard54, we know how important it is to have good upload speeds.

The more devices connected to your Hotspot, the slower speeds will be. Each device shares a portion of the inbound signal. If you stream, game or download, your speeds drop further. In most cases, power cycling your device can help your speeds.

You can reset your network settings to refresh your connection and connect to the best tower near you. 

In the meantime, you can also learn what can cause a low/weak signal and how to improve it.

Let us know if this helps.
