Pixel 6 Server Unreachable

I have a pixel 6 with physical sim card that gets server unreachble when in car traveling through an area that is LTE vs 5G (based on Verizon maps). When I have this issue I can still do a Google hangout but unable to make a phone call. After a while of travel the phone works as normal probably as I move closer to another tower.

Are there any settings that I could change?

Hello ken5775. It sounds like your phone is not automatically switching to LTE (4G). Pixel phone (like most modern smartphones) should automatically switch from 5G to LTE when needed and back to 5G, etc. I am not aware of any setting you need to adjust to make that happen. It is possible your SIM is not provisioned correctly onto the Verizon network; which is something you would need to work out with Verizon customer support. Have you tried calling Verizon support and ask them to check your SIM / phone provisioning onto the network?

Thanks for the response. This is the 2nd SIM for this Pixel 6. Previously the phone would randomly show no SIM. Then in July a new SIM before moving to a new area. Verizon coverage maps show my start location in 5G then I travel through LTE on my way to work, etc. That is when I have the problem. I have had several calls with Verizon to no avail. The phone at the start location (home) shows -106 dBm.

When I work with Verizon about checking SIM should I switch to eSIM?

This issue sometimes require me to redial several time or restart the phone.

The phone also is unable to answer incoming calls when using Android Auto.

I'm not sure about the eSIM. It would not hurt. I use an eSIM on my Pixel 9 Pro and have no issues. There is one thing you can try on your phone: Adaptive Connectivity.

Open your phone’s Settings app > tap Network & internet > Adaptive connectivity > turn Adaptive connectivity on or off depending on the current state. Try it with Adaptive Connectivity in a different condition than it is now.

Note from Google Help: Important: In the United States, some carriers may limit Adaptive connectivity. Contact your carrier for details.

Happy Monday! We know the importance of having your Google Pixel 6 working correctly. Let's gather more info. When did the issue start? Aside from the traveling, any other changes? Who else is experiencing this issue (other account users, etc.)? Where exactly are you traveling?

This issue started after the user moved to a new area in Aug 2024. SIM was replace shortly before moving to the new area due to a previous intermittent issue at another location. No other user's experiencing the issue. Issue is random when the person is leaving their home, via android auto, located in 5G area (based on Verizon map) and travels through a LTE area (based on Verizon map). Eventually starts working when back in 5G. The person also experience the issue in the home occassionally which is in 5G (based on Verizon map). Phone reports a signal of -106 dBm at the home.

The same phone cannot accept a phone call when using android auto. This has been an issue for years. The person typically see the call and has to call back.

Hi Ken. This is just advice: now that you have the attention of a Verizon support rep I would not confuse the phone signal issue with the Android Auto phone call problem. That Android Auto issue is not related to the phone signal problem; it is an issue with Android Auto and/or the Android Auto firmware in your vehicle. If you post the Android Auto issue in the Pixel help community (https://support.google.com/pixelphone/community?hl=en) someone there can help with that problem.

Let Verizon help you with the 5G / LTE signal issue but they cannot help with an Android Auto app problem.

I agree. I do not discuss Android Auto when on the phone. I have had many call with Verizon but no solution. The main question I have asked and cannot get an answer is what part of the system (reception, tower, tower backhaul to Verizon infrastructure, etc.) that produces the "server unreachable" on the phone initiating the call AND the user receiving the calll get one ring and the call drops.

The folks on the Pixel help community can probably help with the Android Auto issues.
