slow internet with 70k bps at 5G network with more than 20GB high speed data available

I did a test to check if my Iphone works properly. I spent few dollars and bought 1G for 1 day esim card from an online esim store. After installing the new esim card, I ran speed test with fast.com and got 290M Mbps high speed data. But with ATT prepaid esim, it shows only 77K bps. Why my ATT prepaid line gets throttled like this while I still have so many high speed data left? 

By the way, my new 1-day 1-G temporary esim card shows the network used is ATT. That is amazing . This means ATT is doing something to my prepaid account in the background that is preventing it from using the high speed data. 

The terms you're looking for are deprioritization and congestion.

Throttling is when your service is turned off or turned down to a maximum. You are not experiencing throttling

Since you are on prepaid your QCI is 8. Postpaid is QCI 7. Business and FirstNet are QCI 6

Hello @andrewl999, we hope everything is going well with you!

Thank you for reaching out to us with your concern, we are here to help.

Here are a few reasons for signal loss or bad signal in general:

This could a location problem. Some outskirts and rural areas get less to no signal as towers maybe located too far off for the frequencies to reach those specific areas, which could be this case. Speaking about frequencies, there are various external devices that interrupt signal strength at your home, devices such as microwaves, refrigerators, washing machines, all run on the same electromagnetic wave length as your mobile carrier. That said, this is prime for service disruption that is undiagnosed.

You can look into our Troubleshoot and resolve (https://www.att.com/support/wireless/) on our website to get in depth review of all your devices. By logging in with your myAT&T account, and selecting the proper service, you can get personalized troubleshooting steps and diagnostics for your signal issues.  

You can also take a look at our Network coverage map (https://www.att.com/maps/wireless-coverage.html?source=IC2Y0H0000000000L&wtExtndSource=wireless-map) by yourself, to check for a possible outage.

We also suggest that you use Wi-Fi calling (https://www.att.com/support/article/wireless/KM1063258/) anytime you are near a Wi-Fi connection. This will help keep you connected in those areas where data speeds are reduced.

Hi formerlyknownas and others, thanks for comments. I called customer support today. The lady Alma quickly solved the problem. I don't know what she did. After I described the symptom, she let me wait for a few minutes and worked at background. Then she asked me to test the internet speed, then suddenly the speed jumped to about more than 19Mbps. Later it became more than 100Mbps. She is really amazing. Really appreciate her help. I think her technical skills are the best.
