Xfinity mobile cell signal booster?

The xfinity mobile cellular signal in my area is terrible, always has been.  I've done everything suggested at https://www.xfinity.com/hub/mobile/5-ways-to-improve-your-cell-phone-signal?linkId=125084615, other than #3 (use a cellular booster); the other options did not help.  Very inconvenient when we lose power, it is impossible to report an outage on my phone with only 1 bar of service.  Also, I recently had a new Xfinity router sent.  Without enough cell signal to use the internet on my phone to enable it after removing the old one, I cannot enable the new one.  Is there any way at all to boost the cellular signal at my home?  If not how do I enable a new router?

Hi @user_9bd096, and thank you for taking the time to reach out to us on our Xfinity Community Forum! I apologize hearing how much this has impacted you, especially during outages. I completely understand how frustrating that must be.

At this time, Xfinity Mobile doesn’t offer or sell cellular signal boosters. Our service a powerful nationwide 5G network, and we also provide access to millions of secure Xfinity WiFi hotspots that can help improve connectivity when cellular signal is limited.

If you have a compatible device and an Xfinity Advanced Gateway (XB7 or XB8), you may also benefit from our Xfinity Mobile PowerBoost, which can deliver faster speeds when connected to WiFi at home or through hotspots, at no additional cost. Please see more about our incredible benefit here:

For setting up your new router, if cell signal is too weak to activate it through the app, you can try:


- Connecting to a nearby Xfinity WiFi hotspot to complete activation

- Using another device or temporary internet connection (like a friend’s hotspot) to get it set up

- Or reaching out to us so we can help walk you through activation options

Please let us know what you’re seeing during setup, and we’ll work with you on next steps.

We get zero coverage while in our home.  Not even one bar.  Instead, we get the feared 'SOS' instead of any bars for coverage.  There's barely a signal even outside, for the entire block we live on.  We have tried all of the solutions that Xfinity suggests, all the Wifi connectivity ideas, everything, and nothing has worked.  It is simply a terrible service for us.  We live in a well populated areas, so it's unclear exactly what the issue is.  As usual, Xfinity offers canned responses, and considers that sufficient.

Thanks for reaching out through Xfinity Forums regarding your issues with your connectivity, @mloungo. I can understand why that's frustrating, especially if you're consistently seeing SOS mode at home and have already worked through the standard troubleshooting. Is the issue affecting just one device, or multiple Xfinity Mobile devices at the same location? Also, when you leave your neighborhood, does service return normally, or do you continue seeing SOS in other areas as well?

 

If you haven't already, try toggling Airplane Mode on for 15-20 seconds, restarting the device, and resetting network settings. These are recommended troubleshooting steps for devices showing SOS or No Service.
