4g LTE only works in home city

Hi, I had to switch carriers for work and brought my Galaxy S9 from Verizon Wireless to AT&T. When I first switched, I was unable to use 4g LTE internet and was only able to use H+ access even after configuring my Access Point Name information. We figured out it was because the AT&T network could not identify what kind of device I had. The in store technician changed the "Device Type" associated with my number to reflect a galaxy s9 and it started working. However, now whenever I leave my home city of the Dallas-Fort Worth area, I do not get 4g LTE internet. To rephrase, I get 4g LTE in Dallas-Fort Worth but as soon as I leave (to places like Seattle, Chicago, New York City), I get H+ as my best data service.

 

My network mode is Global and my APN settings match what is reflected here: https://www.att.com/esupport/article.html#!/wireless/KM1218306

 

I went to an AT&T store in New Jersey today and they made sure all the correct information about my device was reflected in AT&Ts system like IMEI, ICCID, phone serial number, etc. and it all checked out. They had no idea what the issue was.

 

Does anyone have any idea how to make a Verizon Galaxy S9 work on AT&T's network properly?

Hello @aj2wala

 

Thanks for the post.

We have rolled out High Speed Packet Access+ (HSPA+) to virtually 100% of our mobile broadband network. HSPA+ combined with Ethernet or fiber backhaul enables 4G  speeds 5-10 Mbps.

Fiber backhaul is a traffic-management technique that uses fiber to route data in the most efficient way to avoid congestion at peak usage times in markets like Dallas, New York, & Chicago.

Low signal strength on 4G networks may result in lost packets, and higher latency which may appear to you as slow throughput/data speed. Factors such as indoor, building material, metal/concrete walls, and underground may affect signal strength and throughput/data speed.

You can check to determine your throughput using the Speedtest.net App or by visiting http://speedof.me/m/.

We hope this helps!

Hello @aj2wala!

 

You may want to verify your device has the latest software installed. If not, follow these instructions to update your device. Additionally, we recommend to try resolving your experience by performing a reset of your Samsung Galaxy S9 phone.

Okay, I updated my phone and all the AT&T software downloaded to my phone. Now, I don't get 4g LTE anymore in Texas. I am getting HSPAP as my best data connection with download speeds around 10 Mbps. Prior to updating I was getting 4g LTE with ~30 Mbps. Why is this happening?
