Mobile data not working on Android

I have had the same issue for over a week on my galaxy s10 plus. After the aforementioned resetting,airplane mode &the like the xfinty rep replaced my sim card 2 times then told me to order the sim card tray. Installed the tray & that prompted.an update but still no data. Found this thread where the discussion mentioned changing APN & the VZWINTERNET worked-for me.

Is this problem fixed?

My phone is working on XFinity only IF I use VZWINTERNET APN.

Data does not work with COMCAST.RSLR.VXWENTP APN.

Tried new SIM card and it didn't work either.

Im curious when everyone noticed their problem starting?

Also can everyone post what data plan they have and how long they've had it?   

The store rep told me xfinity was starting data plan changes last November.  Maybe the changes went into effect in 2023?  I definitely had working internet around xmas. I traveled to visit family and for sure had internet at the airports.  I don't use airport wifi.  So some time in Jan like 3 weeks ago my 3 LG G8 stopped.  A new sim card did nothing and I cant change the APN.  The LGs have been on the 1gb $12 shared plan since 2019.  The store rep said this was a 2nd gen plan and they were up to 4th gen plans now.  They switched the plan to 1gb $15 shared plan and that basically fixed it.  The comcast.rslr APN stayed the same and is working just like it was before.  The old plan had a $45 unlimited/line option. The new plan has a $30 unlimited/line option.  The samsung A13 is from 2022 and was also sharing the 1gb. It has the vzwinternet apn and never stopped working.  So now both APNs on LGs and the samsung are working fine on new plan.

Maybe those that have phones that let them change the APN to vzwinternet are doing a temp fix to having a "legacy" data plan??  

I have a LG G8 ThinQ phone that experienced the same issues as stated here. Phone stopped working with no network data and the 4G icon was grayed out.

After 2 lengthy calls with the Xfinity Support team and a visit to the local Xfinity store, eventually got my phone to work again as expected. What a mission with the same level of frustrations that everyone here experienced. What I did not buy into as advised many times, was to trade-in to buy a new phone, and that the LG G8 is old and no longer supported. Typical corporate greed, arrogance and just a way to have customers buy more phones after the initial 24mths had passed by. I like my LG G8, it meets my immediate needs and I have no desire to upgrade yet.

On 8 Feb Xfinity transferred our initial 1gb $12 plan to the newer 1gb $15 plan (however on 2/15 I did upgrade from the 1gb to the 3gb shared data plan for more). After the first Xfinity change had no issues on any of the phones. When the LG G8 failed after about 5 days, started to troubleshoot with online call rep and searched thru the forums. Went to the store and rep simply stated that the LG is no longer manufactured (which I was aware of), so no more updates or fixes, then advised to please have a look at new phones.

So today had another chat with another support rep and after a few checks asked me to go to my Settings > System > Restart and reset and do a Network Settings reset. After this reset the phone is now back on the Network Data and the 4G icon is white. Phone is now able to do all functions as expected. Do not know if the rep did any changes on their side to make the phone data network again.

Just happy not into a new phone purchase.  :-))

Well my luck ran out.  The 3 lg g8 phones stopped again.  The 4g icon is greyed out on all 3 phones.  The samsung phone is still working like last time.  Data plan still shows as the $15/gb that was changed from $12/gb. Not sure what levers the store will have to pull this time since the data plan is what its supposed to be so they won't be able to claim the plan is old and causing a conflict.

Just tried the airplane mode, turning mobile data off and on, network settings reset, apn restore default settings.  Full phone reset or new sim card did nothing last time. Clearly something is being changed or being unprovisioned on XM's side.  

I had the same Mobile Data problem with two LG G8 thinq phones. But it got even worse after working with Xfinity advanced tech support.  In January 2023, I realized that the mobile data was no longer working.

Advanced technical support was able to fix both phones remotely in February (after a couple hours on the phone -- if you're reading this, you know the drill).  Then the problem recurred a few weeks later. Yesterday March 18 I had time to seek advanced technical support.  This time after two hours there was no solution.  The agent (a very polite Filipino woman) said the only thing to do would be to get a new SIM card. 

Following her advice, today, Sunday 3/19/23 at 3PM I entered my Xfinity mobile store, where I worked with a store employee, Jon, who succeeded in turning a somewhat useable phone that could make voice calls anywhere and receive text msgs when connected to wifi into a camera-only device.

At no point did anyone say there was a risk this could happen.

 Because it failed activation, it lacks a phone number that could be used for wifi calls.  The employee said there was nothing more to do with this phone.  He said that LG stopped making phones 2 years ago [this is true] and that I should buy 2 new phones.  He also said that there might be a software update that could buy me some time with these phones, but he didn’t know how to do it.

A google search found that the update (Sept. 2022) is available for customer’s of the company whose name begins with the 22nd letter, but did not turn up a similar update for Xfinity Mobile.

The LG website says that the LG G8 ThinQ phone has software support thru April 2024.  However, Xfinity has apparently chosen not to pay LG’s software development and licensing fee. 

LG announced that they were exiting the mobile phone business several years ago and quit selling phones 2 years ago. Therefore it is doubtful that they are updating their software and people who still have LG phones that work are on borrowed time. 

Well, I had the same issue. Noticed in late Jan. early Feb. LG G8 ThinQ. Purchased in 2019 through XM. After hours wasted with tech support, they insisted on sending a new SIM card. Unfortunately, they can't send it to any address but the primary account holder's, which is my father's who lives 2 hours away. I have no car, so he had to mail it to me. Ended up taking about a month for me to get it. Still had to get tech support to help, but eventually got it working again.

I tried everything to change the APN as that seemed to be the problem. No one could change it. The phone is fully paid for & I'm still paying insurance on it. I went through the steps to unlock it, but still couldn't modify the APN.

Just noticed today that mobile data no longer works. After reading all of the recent posts on this thread I refuse to ever buy a phone through XM again. I would rather have a stock phone that the manufacturer could assist me with rather than a phone XM will restrict & load with bloatware. I'll never buy another phone that won't let me create new/modify existing APNs. Very disappointed.

Not sure what to do now as I've paid for the phone at least twice over because of the insurance.

My 3 samsung s23 are up and running. The mobile data is working so far. I wouldn't rule out getting a phone from XM. I think editing the apn has more to do with the manufacturer. My a13 that's a year old let's me edit the apn. The s23 does also. The a13 and s23 both have an apn of vzwinternet. It would've been nice to figure out a way change the LG g8 apn to vzwinternet to test the apn. Even if LG isn't supporting the phone it seems odd that the g8 would continue working every way except mobile data???? Calls and texts on the network but the network doesn't let it get on the internet???? I thought of rooting it before getting the s23 to see if the apn would be accessible but just didn't have time. Also I never get the insurance on phones. Unless you need to file a claim right away it doesn't seem worth it. Basically it's like a 2nd payment each month and I think there's like a $100ish deductible and many times you get a refurbished replacement, not even a new phone. I can save that money and put it towards a replacement if I ever need it. I'm not clumsy. I don't lose phones or drop them in the toilet. Especially when the cost of the phone ends up being 200. Maybe if you buy a full price $1k-1.5k device it might make sense. I digress.

I just want to throw my story in the mix too. My wife and I both have the G8 ThinQ, My phones mobile data still works but her doesn't. The difference between our two phones? I haven't update the software on my phone since 2021. SO it is definitely an issue Xfinity's side. I have also talked to reps from LG about it because Xfinity assures it was the software from LG that changed the sim on my phone and caused the issue. LG hasn't released any updates since 2021 for these phones. My phone with the old software still have the VZWINTERNET, hers with the updated software has the new one that doesn't work. I have updated sims twice on her phone. Somehow miraculously they fixed it at the end of February that lasted maybe a couple weeks then it stopped again. Of course they have no record of what that person did to fix it, so no one can recreate it. I have probably spent 15 or more hours on the phone with support they have open support tickets with Verizon, they closed all of the tickets without telling what was done or found, even though they reassured my multiple times that I would receive an email and a call once they heard back from Verizon. One agent I talked to said he opened another Verizon support ticket, but there is no record of it in there system. There is no one Above the support team to handle customer issues when they can't or wont do anything. This is ridiculous and Xfinity needs to be better!!!
