AT&T, like many cellular carriers, throttles network usage. This can affect your streams.
To get the best quality streaming from your carrier:
- Use a modern phone and hotspot. 5G and UWB help.
- Read the fine print for your data plan. "Unlimited" devices are often throttled after a specific amount of monthly data.
- Activate "maximum video streaming quality" for the phones you use to stream. This may require an added monthly fee.
- Note that carriers only throttle at at certain usage levels and at certain levels of cell tower congestion. A doubleheader can have one game stream well and another game stream poorly.
To upgrade AT&T for maximum video streaming quality:
1. Turn off Stream Saver
AT&T describes "Stream Saver" is on by default and limits streaming video to 1.5 Mbits (barely suitable for 480p resolution). Here's how to turn it off:
This page describes Screen Saver and has a Stream Saver FAQ.
This page has directions for AT&T Wireless, AT&T Prepaid, and AT&T business accounts.
2. Consider plans with higher traffic priority and no rate limits
At the time this article was written, AT&T's Business Elite plan gives higher priority to traffic with no network management, up to 100GB/month.
