Mobile data not working on Android

Hello @user_130b6a, we can certainly understand how frustrating it can be to not have internet access when outside of the home. Make sure that your mobile data is on. Have you confirmed that your phone is showing 4G LTE or 5G on the top of your screen?

Darn, sorry to hear you're still having those issues. Please reach out Xfinity Mobile experts that can help troubleshoot further through the options provided above. We can follow up with you in a couple of days to see if you've been able to reach them and hopefully this issue is resolved. 

Check the following

Settings>Cellular>Data Roaming "On"

Next to your signal strength and battery indicator it should say what Data connection you have (Must disable Wifi to confirm). It's either 4G/LTE or 5G depending on your device.

Hope this helps

I feel better already. It's not just me. Though I'm now upset with Xfinity. Where's the solution???

It doesn't appear that you got an answer. I have the same problem: Android mobile doesn't work while iphone on the same account works. With roaming on, I have 3-4 bars. With roaming off, There's a small x near the top of the tallest bar....my home requires mobile data to work for both android and iPhone.

Same problem, mobile data on Android phone is not working (iPhone is ok). Power cycling, taking battery out, roaming on/off - nothing helped.

Sent text message to 1 (888) 936-4968 and reply is "can't connect you to an agent right now".

Noticed the problem mid-Dec but have been putting this off hoping somebody will post a solution and I can avoid dealing with customer service. 

Same issue here on both my Samsung S9 phones. Spent almost 2 hours talking to 4 representatives yesterday but no one could fix or was aware of this issue.  I never got to a technical expert. Tried reset of APN, etc. Waiting for email back as someone is supposed to be working it and get back to me. They want me to get new Sim card if they can't figure it out in a few days. It is obvious to me something has changed on the xfinity side or the current APN does not work. Will post back when I get a resolution.

I got my mobile data to work! Somewhat. 

NOTE: Try at your own risk. The APN setting also reverts to the non-working name at some point while I'm using some apps(browsers, online ordering) so I need to change it back to the working APN.

Original, non-working APN setting:  COMCAST.RSLR.VZWENTP 

New, working APN setting:  vzwinternet   (info source: https://www.apnsettings.org/us/verizon-apn-settings-for-android/)

Did a little more research on the internet. Found another link similar to Xfifi that says to use "internet" as the APN. That did work. Interesting that the first time I restarted the phone the APN went back to original setting.  Second time I restarted after fixing APN again it stayed with the new name. I am unable to add a new access point (add button is greyed out). I can only edit the current APN. My hope is all this works correctly and Xfinity bills us the same as using the original APN. By the way I have not heard back from Comcast after 2 days. Shocking. My source was this Xfinity Mobile APN Settings for Android and iPhone 2023 - 3G 4G 5G LTE Internet Setting (apnarena.com)

I too appear to be having the same problem.  I think the problem started on Jan 21, this past Saturday.  We have 3 LG G8 ThinQ and one Samsung.  Lg's are from 2019 and have had mobile data access the whole time.  The Samsung was added last year.  It is working fine.  I was on the phone for an hour or so on Sat with cust service but nothing was fixed.  We went through all the basic troubleshooting that everyone else seemed to go through...airplane mode, restarting phone, data on and off, wifi on and off, network settings reset, etc.  In the end they thought there might've been a 4G outage that would've ended around Sat 6pm.  That time has past so obviously not fixed. 

The LG phones all show a grey "4G" box at the top and I think they are supposed to have up/down arrows underneath.  The samsung is a 5G phone that does not have 5G data.  All 4 phones share 4G data of 1gb/$12.

Because of this thread I checked the APNs.  The Samsung has the APN vzwinternet.  The three LG have the APN COMCAST.RSLR.VZWENTP.   I can't change any of the APN, as far as I can tell on the LG.  I check every setting and menu when I get a new phone (I mean literally go through every menu and setting methodically) and I have a vague recollection of seeing vzwinternet on the LG as the APN.  I even tried under the APN menu to do the "restore default settings" but that did nothing...it just said restore is complete or done.  The mobile network menu greys out if airplane mode is on or the sim card is pulled.  Neither forces the phones to connect to vzwinternet.

Could the APN have been changed with a software update?

Can cust service change the APN on their end or would this require a new sim card?  Can the APN be changed in the Xfinity store?  Would they even know what I'm talking about? 

I really don't want to have to explain this all again to another rep on the phone and mention the APN thing and have them not know what I'm talking about.  The rep I spoke with was very friendly and nice so no complaints there.

I was reading this today. Hours of wasted time on the tech support.

I just got back from the local Xfinity Store in Santa Fe, NM with a working phone.

He figured it out in 10 min and replaced the SIM card.

Right Network, mobile data etc seems fine now.

Good Luck

I faced same problem. Xfinity support could not fix issue.

I changed name in APN to Vzwinternet (all uppercase) and then it worked.

Im going to the store today to try new sim cards. If that doesnt work I'll have to call xfinity for a 3rd time to see if they can get LG support on the phone.  Maybe LG has a way to put phone in an administrator mode that allows the apn to be changed to vzwinternet.

I've tried all the tips online about how to get a non-changable apn to let you edit or add an apn.  None of them have worked.  The LG G8 whenever the sim is pulled or airplane mode is on, the mobile networks option is greyed out so I cant even try to delete the apn to get it to reset when turning airplane mode off or popping the sim back in.

Its fixed!! And the solution wasn't at all what I would've thought. 

I went to the store in the afternoon so it would be slow in there.  I started to explain what was going on and mentioned possible issues with the APN. Of she had no clue what I was talking about.  So we changed the sim card on the phone I had previously done a factory reset on in case we needed to do it again.  I immediately saw that hadn't changed anything. 4G icon was still grey.

So she called her tech support on the phone.  Store rep mentioned to me we were on a 2nd gen data plan and that there's a $30 a line unlimited plan. I immediately said I don't want unlimited, we hardly use data. So her and the phone support changed the plan to the 1gb $15 5G plan. Then she did the network reset on each phone and I powered each off then on and that was it. 45 min later I was leaving with all the phones working.  I don't even think the network reset would've been needed. Powering the phones off and on probably wouldve sufficed.

A new sim card did nothing.

There was no issue with the APN.  They all stayed the same. 

I could've changed the plan by myself at home from the 1gb 4G $12 shared to the 1gb 5G $15 shared and saved hours of headaches.

She said around last November xfinity started to do changes with the old data plans. Would've been nice if we had been informed.  The 4G LG G8 are all working fine on the 5G 1gb $15 plan. 

I doublechecked everything b4 leaving the store.  I checked the xfinity mobile app to make sure everything was right. APNs were fine and hadn't changed.  Billing cycle dates were the same. Phones and numbers were correct for each line.  Nothing was accidentially changed to a "new" line. Data usage was correct in the mobile app and hadn't "reset".  Upgrade to $15 1gb shared and problem was solved.

4G icon in status bar are all white again with arrows showing underneath.

Thank you for the update! I did the same thing this morning and unfortunately his phone isn’t working yet. We will probably go in and try to talk to them again.
