Mobile network not available...no calls, no texts but receiving emails

Hmm, sounds like me. Yesterday my a715g uw went totally bonkers, no network, no service nothing.  Texts pending, yup. Spent 2 hours with teck support- switched out sim card. Now that one works, BUT my s20 with NEW sim will not even put up a phone number.  Another 2 hours and NO FIX> About to hit them up again.

Update: My brother found a solution for me. Put your phone into airplane mode for a minute and when you turn it back on it should reconnect and be fine. To quote my brother:

"It has to do with how your phone attaches to a tower. By turning it into airplane mode it forcibly disconnects and turning it back on requires it to look again for the strongest connection."

I am having the same issue. It seems to happen when you log into WiFi. If you log out of wifi, you will lose network connection. If you restart your phone it works just fine, until you get to wifi again. Does that sound the same?

Yeah, did  that too.  Day 8 and both phones are still NOT on Network. INSANE!

I have a Samsung Galaxy A50 and have had the same problem since the software updated January 3rd. I contacted Xfinity Support and they had me reset my network settings and reset things on their end. Only helped temporarilly, and I lost all my WiFi and Bluetooth settings in the process. The Airplane mode trick works, so thank you @thenowhereman3 for that tip , but is still a pain to have to do whenever leaving a WiFi area. I've also noticed that the phone no longer connects to XFINITY WiFi when available. It stays on the mobile network. Suspect it is also related to the software update.

Day 8 for me!  Customer resolution involved, but still not resolved.

 I went to Xfinity store and they reset my network. I didn't try doing that myself as I thought I would lose everything. I did have to reconnect bluetooth to my car, but it seemed to work. 

Now it seems I am not always automatically connecting to wifi. They tell me I have used 80% of my by the gig. I rarely go over 1 gig, so it must be disconnecting from the wifi. I will try the airplane mode thing, if I can remember. I wish I never updated.

@ComcastChe  you realize that is not a solution, right? It is a pain in the butt work-around but not a solution. So many people are having this issue, why has it not been corrected? We have gotten absolutely nowhere with tech support. THe phone works fine until it disconnects from the wireless network. 

Hi @mki29, thanks for following up. Sorry I wasn't clear in my reasoning for providing the contact information in my first response. The reason I advised Xfinity Mobile customers to contact that team for this issue is because us agents who work on this forum aren't fully trained to handle this type of technical issue. We understand how this is affecting you all and want to make sure we are pointing you in the correct direction to get this fixed in a timely manner. I hope that helps. This thread will now be locked. If you need assistance with anything else, feel free to start a new thread, and we'll be happy to help. 

My phone keeps disconnecting too. Did anyone find a solution?

Same issues. The airplane mode on/off is not an acceptable solution.

Has anyone determined an actual cause or permanent fix to this issue?

I have the same issue, I have 3 phones, 2 new from comcast one transfer, Some calls go through some don't, either we get the wireless customer you are calling is not available, even calling a home or business phone, or 3 busy beeps and then a dead line, This happens with a iPhone, A71 and a note 8,

I have contacted support who has escalated the issue, but reading here they know they have an issue, If this isn't resolved soon I will be forced to move to another vendor, as airplane mode is a unacceptable resolution, Note, Xfinity uses Verizon network and one of these phones came off the Verizon network and never had this issue.

Same here. Happened in January and resolved by resetting network. Now April,  it's happening again! Sick of this service provider,  switching ASAP!!
