Phone no longer activates 4G LTE

So recently I flashed the Jun 14th revision of Paranoid Android. I'm not sure if it's actually because of that ROM, but ever since, my phone hasn't been activating 4G LTE, even on different ROMs that previously had. Like, Synergy ROM r484 had no issues and it would activate 4G, but now it won't. Same with Hyperdrive ROM.
I still get 3G and calls go through (another problem I had was that the phone application kept force closing), so I'm assuming the phone just isn't contacting Verizon to activate itself.
TL;DR: Is there a way to manually activate 4G by calling Verizon or...?
EDIT: I'm now running the stock OTA MF1 update (courtesy of beans and scott) with the MF1 baseband, but still no 4G.

Did you use *228? That fries the sim card and you won't get 4G. Otherwise, I'm not sure what to tell you, but on the bad advice of a vzw customer service rep I fried my sim card that way.

To my knowledge, all Verizon 4G LTE phones don't allow you to dial *228 at all because of that particular issue.
I pulled out my sim card, and there does seem to be some sort of discoloration on the gold contacts. Is it possible to just get a new one in the mail or pick one up from my local store? I've been prowling through the verizon forums and have had no luck yet.

Any Verizon store will have 4G Sim cards. They didn't charge me when I needed a Micro Sim for my Galaxy S3. I have heard that a bad Sim can cause
your problem.

When I bought my s3 the day before it arrived I went to my Verizon store they sold me one for 9 dollars. Also *228 no longer fries the sim it doesn't update either it just loads the activation from the sim.

So when I dial *228, I get this message: "A Verizon Wireless SIM card has activated your service and updated your phone's roaming capabilities."
It doesn't do/change anything; I'm still stuck on 3G.

Yep as in the Prl and activation is pulled from the sim to get that updated you need to call Verizon and ask them to push you an update provisioning they do this every so often normally but with the md3 update the radio and prl was flawed the mf1 was to fix the issue downgrading and getting reprovisioned should fully roll you back.

Sorry, I'm not fully understanding what you mean. What do you mean downgrading? Isn't MF1 and upgrade to MD3?
And what is/how do I get reprovisioned?
Lastly, by "fully roll [me] back", you mean get 4G back online, yeah?

I posted that from before mf1 was rooted and rolled out to all
I meant for it to read to fix the issue rolling back to mb1 from md3 will help the issue and downgrading should fix the new issues
Upgrading from md3 to mf1 is another way to potentially fix it but knowing verizon im sure there is a broken thing somewhere in it.

This is what my about phone says right now. I'm pretty sure I have everything up-to-date. Not entirely sure what it says under kernel version means.
So if it's still not fixed after flashing the new mf1 build ROM and mf1 baseband, do you think it's something else?

From what I can tell it looks like your using the ota version the only other thing you can do is request Verizon provision your phone from what has been said is people went from 0-1 bar to 3 steady.

You're going to have to call the support line and tell them you are getting terrible signal and such and you read on the support forum that provisioning can help what they will do is push the activation to your phone again this will update the prl and make sure it has all the settings correct.

I've gotten LTE w/o 3g and 3g/1x without LTE by playing with manual APN setting. But fixing it requires a prl 'push' or revalidation by upgrade points because the merging of d2vzw and the d2 variants has made a lot of little issues and how Vzw handles its APN s/handoffs are more involved since sprint. So other than doing that you can re go through your ROM and use this post to http://forum.xda-developers.com/showthread.php?t=2069850 manually fix your ROM by extracting an old backups settings and replacing each and every file relating to Vzw s APN telephony etc handlers. Its a pain either way but I'll collect current ones for others to use and look into signing a flashable zip for PA users.

I know this is an old post, and when I searched this one was the only real post that discussed this problem.
I did the *228 update and lost 4g, So I am going to try and get Verizon to provision, but just to add to the conversation:
Will flashing a custom rom fix this? Is Flashing back to original factory stock a fix as well? [Reading the above posts didn't make this super clear to me.]
Thanks

jerrt010:
I just got in the same situation as you the other day and very curious if you get it resolved. On CM11m8, did *228, and then promptly lost LTE. Noticed the the PRL went from 15319 to 53481. I read somewhere else on XDA that the LTE PRL starts with 15*?

I'll just add to this that I did the *228 and couldn't get back on LTE. I was on Slim at the time and finally after a couple of weekly builds I decided to wipe everything on the next weekly that came up and my LTE returned.

woohoo, got my LTE issue fixed!
Lesson learned, do not *228 and update the PRL for a smartphone!!
Root issue was the Verizon PRL switch from from 15319 to 53481. The VZW tech support was very surprised my phone let me *228 to begin with. The system showed the phone updated the PRL to 15319 last month. Tech support level 1, reprovisioned the phone but that didnt help. Tech support level 2, re-pushed the PRL, but it didnt appear to get downloaded after 2 reboots. Next, Level 2 resubscribed the phone to the system, but that didnt work either. Next they had me boot into safe mode (learned something new today... Power button -> click and hold on Reset item and then select yes to the safe mode dialog). In safe mode however CM11m9 (I just updated last night) the com.google.androidui (or something close to it), kept crashing... so the phone was unusable. Rebooted again, back to normal mode and it was back to LTE! The PRL was back to 15319. Looks like the PRL repush from VZW eventually came through and was the solution.

Yep! this is a know issue with using *228, it will wipe your 4G. The best fix is get a new SiM card from Verizon and the re-provision should work right away.

Sim Unlock Suggestion (T-Mobile & Metro PCS)

So i assume that everyone has heard of the new Device Unlock app preinstealled on Devices sold by T-Mobile and Metro PCS. They present it as a new way for carrier unlocking devices in an easier way but the catch is having to meet THEIR requirements like using their service for at least 90 days (Prepaid) or fully paying off the device (Postpaid).
The problem is that they are practically forcing us to throw money at them to get anything we want even though we prepaid customers purchased our devices outright. Sure for some people the device was sold at a discounted price so it would make since for them to gain that money back through service activations, but that still wouldn't equal the amount you would be paying during a 90 day period. On top of that there are people that didnt get this device at a discounted price, therefore we shouldn't have to be "Limited" like those who did.
So after doing alot of research, since i too have a MS631 Stylo, it seems that this device was reprogram to generate sim unlocking remotely, but that doesnt entirely mean it's impossible to bypass this like most people say. This isn't iPhone, this is Android. Completely open sourced and with root access, we have the ability to manipulated any given SOFTWARE function.
Looking through files etc. It seems the sim unlocking menu was removed. Doesnt take a scientist to do that (Nice job Metro and T-Mobile). Simply sideloading the SimUnlock Menu apk from another LG device will bring it back. The dialer codes were also generating null output. On the MS631 the dialer code is 2945#*631# if im not mistaken. Entering this defaultly will generating nothing but the digits being erased. Installing the sim unlock menu from the LG G2 reactivates this function. Using the same dialer code will bring up the sim unlock menu successfully but none of the options will work. Choose any will greet you with a nice message stating "Your phone is not personalised". This means theirs no internal script or file locking your device like before, this officially confirms the unlock proccess is server sided. But, you have to take into consideration that the SimUnlock menu only reads from a specific directory to locate and process the unlock code when entered. So now the question relies on where the unlock is triggered on your phone from their servers.
Removing the Device Unlock app will do nothing since it's nothing but a tool to proccess this unlock via sever then callbacked to trigger the unlock on the device. So i tried flashing the T-Mobile KDZ thinking it would automatically unlock my device or at least lock it to the T-Mobile's Network instead which is the service im trying to switch to anyway. Flashing the KDZ is successful but nothings changes. Im still greeted with the Network Lock message upon entering a foreign sim, even a T-Mobile sim. Users in the S6 forums have had success flashing the Metro PCS firmware on their T-Mobile S6's to bring up the Unlock Screen, but the thing with their situation was the device unlocking software was not programmed into the Metro PCS software. The Device Unlock was programmed on Both Metro and T-Mobile stylo firmwares.
How can your phone still tell you're locked to a specific network even though youre using a different firmware? Well apparently the device unlocking function is programmed in the modem. To my knowledge Metro and T-Mobile share the same modem for the Stylo, meaning flashing another firmware may have worked on other phones but not on the Stylo considering the status of the modem has not changed.
So here's my suggestion to get the Stylos unlocked or at least bring back a work Unlocking menu and bypassing the Device Unlock app. Port the international rom to the Metro and T-Mobile versions. Don't say it's impossible, because it's been done on several devices and people still do it to this day. The international versions dont carry the same modems nor do the cricket and boost versions. It could also be possible to look at porting those too. It would be harder to port due to the T-Mobile and Metro versions being the only ones to have 16GB or Internal and 2GB of RAM, but it's possible. If there are any devs willing to do this then that would be great. This isn't just a solution for the LG Stylos but potentially for every other phone with this new unlocking function. Carriers are trying to control us again and it's time to fight for our rights to what WE OWN! Thanks

90 days doesn't seem to terribly long to wait.

You're right it isn't. But there are people that buy T-Mobile devices strictly for the Unlocked Bootlader and having to activate service with them for 90 days and dish out 3 months worth of money just to use it on their service provider is a bit far fetched. Like in my situation, I bought the Metro variant on CL because no one was selling the T-Mobile variant except the T-Mobile store which cost almost $100 more. I was told my T-Mobile sim would work in it since its the same network anyway. Well it was my fault for not researching and seeing that even though metro works on T-Mobile devices out of the box, T-Mobile does not work on metro devices unless it's unlocked. According to metro in order for me to unlock it I have to have service with them for 90 days. So now I'm forced to cancel my T-Mobile service and hop on Metro, when I don't won't to because of the crappy coverage, for 90 days just to use my main service provider afterwards. It's too much for one simple thing.

Now that metro ditched their cdma network i do believe they run on the same towers. You could also change the apn to t-mobile as well. And Metro is cheaper and doesn't throttle the data speeds on their unlimited plan.
I used around 50gb in two days with pretty fast speed.

Changing Apns wont work as the apn never sticks. T-Mobile rep confirmed that even though Metro runs on their network, they aren't allowed to utilize all of their towers which explains the crappy coverage with them. Based on what T-Mobile said, there could be 7 of their FULL LTE towers in an area but the Metro network could only use maybe 1-3 of them. Thats the price they pay for being an MVNO instead of an official carrier. That's great that you get good speeds with Metro, but unfortunately in my area i don't.

All in all, the new network lock seems to point out the actual locking/unlocking process is being done in the modem.
If using a new modem image (taken from an unlocked version) won't work by default (which I tend to think will be the case) then, the network lock validation process (based on the IMEI) must be done within the modem???
Anyway, I think this whole new locking process is kind of abusive. I read many forum threads about people complaining that they had to either address to FCC or try many times with the TMO support to get an unlock for their phones even though they should have been able to do it from the app because they met the conditions.
I think this new abusive unlock method will continue to plague many new phones in the future.

If you use this hidden menu by dialing 277634#*# you will be able to APNunlock which lets you deleted defult apn and make new Apn's and they will stick
P.S im assuming metro variant have the same dialing code for the hidden menu. Images below.

I've done the Apn Unlock already and even though i change the Apn settings, nothing changes. I still can't use my sim because i get presented with the Network Lock screen. I've used the dialer code and I've used an app called Shortcut Master and accessed hidden menus through there to see if i could find anything in the modem pointed to a Network Lock

Exactly! Even people who do meet the eligibility requirements still have issues using the app. When i use the app i cant even get to the permanent unlock option. It says "Device not recognized by your service provider, please call customer care". I looked up the error and Metro says it's due rooting. I've flashed the stock KDZ, removing root, several times and the message still comes up. My device actually does meet the eligibility requirements as it was active with Metro for well over 90 days but the app always throws an error. Metro has no clue how to help me and basically just says "Oh well". This new unlocking is just bs and they know it. They're trying way too hard to force people on their network. Thats bad business. The more people figure out about this stupid unlock system, the more customers they lose. I know for a fact it's modem related. Flashing the T-Mobile modem won't do anything because it's the exact same as Metros modem. The only other modem i can think that could unlock this device is Fidos Variant but i feel thats just gonna cause a brick. I remember flashing Fidos KDZ and i got a super hard brick, having to send the device to LG for repair. There is an international version of this phone but theres no way to get my hands on the modem.

He wouldnt show his method obviously because he was charging people for it. So there must be away to get rid of this if the guy did it himself

S7 wont go into LTE tmobile unlocked/cricket sim

Sorry if this a repost of any nature I purchased a phone off a guy in cricket the other day who said his s4 was running faster then his s7.
so i got the s7 cheap.
I have the s7 now everything works except these factors:
1. the imei is 15 chrs and the imeisv is 2 chrs
2. i cant get it to go into LTE and the preferred networks are all 2g and 3g.
3. i have tried changing the APN's but to no avail when i type *#*#4636#*#* into the dialer i cant change it from wcdma prefferred to anything of the cdma/gsm/lte auto
the weather is stuck on London aswell.. if that helps any? and only allows update from 2g/3g network
im new to this anby havent messed with odin yet. it is unlocked for the wifi hotspot which cricket doesn't allow. which is odd to me.
tldr:
pretty much my problem is the internet is slow and the data is slow i want to be able to get it to faster speeds
any help would be appreciated

From what I've heard in other threads, I think that you have to call your carrier so they can unlock the phone. Then you will be able to use LTE, but since its the exynos it will show it as 4G, its the same thing.

With this code you can change bands priority ##3282# but you will need the MLS code.
I'm not much of a help as I'm from Europe and dont really know about carrier phones. Seems like T-Mobile, for example, has unlocked only the bands it uses and not all the bands so you can't go to another carrier easily.

I have the T-Mobile Galaxy S7 and use it on AT&T, so you'll have no problems. Dial *#2263# and hit select all bands then hit apply band configuration. Exit and you should have LTE working. To confirm dial *#0011# and see what LTE band you're connected to.

I think you just got a lemon (bad) phone from the Cricket dealer. Try and get a warranty exchange through Samsung.

Not sure. Hopefully.

Galaxy S8+ on Xfinity Mobile

OK. Like the title says. I have two Galaxy S8+ unlocked from Samsung. They are the U1 models. I ordered two LG X Power phones from Xfinity with the intention of using the SIM cards in the S8. I had to add the APN settings from the LG phones to get data working. The problem I have now is that I can receive text messages but I can't send them. Also when I go under call settings/more settings I get a failed to read data (Network or SIM card error. The S8 had extra APN settings that the LG didn't have so I'm not 100% sure that it is right. Anyone have an unlocked S8+ on Xfinity Mobile? Thanks in advance for any info.

OK. So I got text to work now. I had to do the carrier fw flash. Now I have another problem. Everything looks like its there as far a Xfinity APN, CSC, etc. Just having problems with 4G now. It wants to stay in 3G and the only way I can get it on LTE is to change from Global to LTE/GSM. It connects to LTE but then I can't make phone calls because there is no CDMA network. It's suppose to be VoLTE but for some reason that's not happening. Starting to wish I had just purchased the phones for Xfinity.

So...from what I gather from tech support at Xfinity, you can't just take a SIM from the LG X Power and install it in a Galaxy S8+ even if everything has been flashed. The APN settings appear correct comparing to what was on the X Power. All of the Xfinity software is there from the flash. It SHOULD be just like a Xfinity branded Galaxy S8+. I can't find any dialer codes that work to see what bands are enabled and priorities. Tech support said this would never work. He said you couldn't buy a used GS8 from someone and activate it. He said it becomes a third party BYOD at that point. So these Xfinity GS8+ phones sold on eBay to work with Xfinity probably won't get activated. I hear of people taking the SIM cards from the cheap iPhone SE and installing in them in iPhone 7s. I don't understand what the difference is.

Uninstalled an Xfinity sim card on a Verizon G6 and it worked fine. I now have a S8+ I got from Xfinity but I also have a S8 I got from Verizon at home. I'll try it tonight and see what happens.

Installed the SIM card back into my LG X Power. Now I can't get 4g on that thing.

I don't see why it won't work. I bought the lg x power too, got it to work with an old Nexus 6p, my wife's iPhone 6s+ from Verizon, and currently with a mi note 2. The APN settings need to be right, and Volte needs to be turned off. I know the phones support it, and so does Xfinity mobile, but that might just be reserved for the phones bought through them.
Also, for texting issues, try different texting apps. I had issues with Google messages, but tried textra, and things worked great, including mms.

4G started working on it's own for both phones. Looks like there was a PRL update that corrected it. I exchanged the LG X Power for the X Charge because they are support VoLTE. Got the phones and had a mod on Reddit to get the account provisioned for VoLTE and everything started working! A tier 2 tech called to tell me they had enabled it. I asked about my wife's phone(she was using an S8+) and he said it had showed up as a Samsung device. Told him I had already installed the SIM card back in the LG X Charge and when he looked again he confirmed it. Said he would get with tier 3 and call me back. About 45 min later VoLTE was working on her X Charge. Installed the SIM back in her S8+ and everything is working properly.
I guess I jumped the gun on this anyway. I got the unlocked S8+ because Xfinity didn't offer insurance and I wasn't sure they were. There were complaints of Samsung not offering there insurance on the Xfinity phones. Anyway, now Xfinity offers insurance and they have $200 off the S8+! I only paid ~$640 for the unlocked versions. Not a big deal but I was trying to get this done before July 31 because they said unlimited was going to $65(wife uses a lot of data).

Hello, new to this forum but stumbled onto your post since I have the exact same issues you had but with S8 instead of S8+. Would you mind sharing where you were able to find the FW for xfinity? Thanks!

I'd love to know as well cause I still can't send any text messages, I can receive texts, use data, and call though. I flashed the G955U1 firmware (USC) version and its much faster but I'd love to be able to use the U1 firmware but be able to text.

Same here, if anyone can provide some help on being able to fully utilize the unlocked Samsung S8 version with Xfinity sim it will be great. Phone calls work, and can receive texts but no mms,

Same problem for me with my unlocked S8 from Best Buy. Everything works except sending texts. I chatted with Samsung support and had already tried everything they suggested . . . factory reset, safe mode, different text app, etc. Nothing worked. They wouldn't touch the APN settings but I tried the same settings my LG X Charge from Xfinity has. Still nothing. I used this phone for three weeks on AT&T before switching to Xfinity and texting worked fine. So I know the phone is fine.
The only difference in the Xfinity APN settings on the LG phone is that the LG phone has a three digit username and password that is blanked out. I don't know if this makes any difference or if anybody has seen similar APN settings for Xfinity. This is so frustrating that I can't use my $700 phone with Xfinity.

did unlock xfinity s8 + when i insert t -mobile sim card i got 4g but getting this message
invalid sim card detected insert an xfinity mobile sim ........i did unlock the phone with code when i dial *#7465625#
everything off even netwok

I flashed Canadian firmware. Then I flashed the xfinity firmware, with the xfinity csc and I get Volte, and texting works. I originally had tmobile, flashed the us unlocked firmware and then I switched to xfinity mobile and I was having same issue as you guys until I changed firmware.

Thanks, but I've tried many APN settings including these. Still no texts working. Just ridiculous. I'd really rather not flash my S8 multiple times in order to just get texting to work.

Why did you flash the Canadian firmware first? And did you need root before flashing? Did you follow a certain tutorial for the flashing?

Question SOLVED - Verizon Hotspot not working?

Hey folks,
So I'm in hour 5 with Verizon Support trying to solve this:

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

I've been with Verizon forever and I've never had this problem before. Hotspot has worked fine for like at least the last 10 years when I have brought my own device. Now they're saying because its a non-Verizon device they can't guarantee all features will work. That makes logical sense, but I"m not using some off brand Chinese knock-off here.
Anybody else has this problem? Did you find a solution?
I have reset APN's to default, I have reset network connections, the Verizon person removed and added the feature to my line. So far nothing has worked.
The same thing is also happening to my wife's P7P as well.

Works fine here. I have a non-VZW P7P. Maybe try making your hotspot name something simple and without special characters....just a guess, but cant hurt to try

I'm Verizon, unlocked 7 Pro. Have you tried having them set you up with e-sim? It'll be a clean provision and maybe that will help. My hotspot works fine as well.

For what it's worth, I have an unlocked rooted P7P and am able to get my hotspot working...
I would think that it's simply on the Verizon server/system side. If you use Android Messages, does the chat/RCS enable/turn on as well? I can't think of other carrier/Verizon enabled "features" but I'm sure there's more, but you should try them also. I would try to narrow down if it's specifically and only hotspot or your total connection to them.
*Also, if it makes a difference or not, I am not on an unlimited plan, but a tiered allotted with carryover data plan...

A sincere thank you to each of you for replying, I'm hoping someone will have a nugget of information that will lead to a solution.

Thanks, but default simple name didn't work, and single word with no special chars didn't work. I also tried each of the different security options and none of those worked. I appreciate the reply, this gives me hope.

I haven't. I'm using the same sim that was in my OnePlus 9 Pro a few months ago and worked fine in it. Maybe something to try though if it comes down to it. Curious if the other posters are on e-sim?
Another user with a working hotspot with the same device, this gives me more hope. I worked with like 7 different Verizon people and more than one claimed to remove the feature and put it back.

It sure feels that way since the exact same thing is happening to my wife's P7P, with the same sim that worked on her Pixel 4 XL. Everything on the phone seems to work fine, RCS is good. It connects to 5G.
I appreciate the mention of your plan, because I wondered if that could be a contributor, I am also on an old tiered plan with rollover.
I tried contacting Google Support after the Verizon folks threw in the towel, but they were disappointingly useless, and after like 5 minutes asked if I wanted a warranty replacement.
Each of you gives me some hope that I can get this working, but on the other hand it diminishes my hope that a monthly update will fix it, if its solely my problem, and everybody else is working OK.
Anybody else got any ideas?
Vzw support reached back out to me and wants to try again tonight after work, so we'll see how that goes.

I have an unlocked phone (from google), rooted, on Verizon's network, and it works fine. Are you saying you have a phone that is not Verizon branded, on Verizon's network, and hotspot doesn't work? Are you rooted?

I would request a new physical sim as well. Everything worked with my old VZW sim, but the VZW system said I wasnt "registered". I requested a new sim, and that did register properly to the VZW system. In both cases, the Hotspot was working properly. GL!!!!

I would try a new SIMs for both of you. I was able to get away with using my 4G SIM from my Pixel 2 XL onto my Pixel 5 and was able to get 5G fine (hotspot worked in all cases as well). I was able to get it working pretty perfectly when transferring it to me and my wife's P7P -- 5G, hotspot, RCS everything worked just fine -- but only upgraded my SIM because I would have this alert/notification in my My Verizon app & My Account (web portal) alerting the necessity of "registering" my new device and when I would, it complained that it wasn't properly registering into the system and would require a new SIM. Point is; even if everything seemingly works with older SIMs, you never know why/if things might guck up for whatever random reason because of it.
Also, I don't know if you have an unlocked bootloader and are familiar with flashing Full Factory images onto your phone, but if you are (or if you are not, you can consider using the official Android Flash Tool or PixelFlasher), I might consider (even if it might be downgrading) flashing the Full Factory image that was specifically for Verizon. As I understand it, that firmware update has specific modifications to the radio that is tailored & beneficial to the Verizon stations/signal/servers. Just a thought that maybe it might "reset" or set right your & your wife's P7P radio properly to Verizon's including ability to hotspot and/or properly registering your phones to the system...
Good luck!

you know, there was some weird "registration" communications when I first inserted the sim in this phone about 5G, but there has never been any coverage or connection issues, so I figured whatever it was was resolved. I will request a new sim from them and see what happens.

as mentioned to the quote above, I now remember that I did experience some weird 5G 'registration' issues when I first got the P7P (my wife did not, but her phone exhibits the same issue). I'm going to request a new sim and see what happens.
I am not rooted or rom'ed on this phone, but I was a flasher back in the day, and am comfortable doing some tinkering. I thought about doing the old dun provision check (if that's even still a thing) but have been pursuing conventional support methods so far.

This comment triggered a thought...have you tested your hotspot under LTE, 3G, and 2G/1x signals? I would change these under the radio special menu versus the toggles that's in the normal network settings....I'm curious if it would work on any of these lower signals and/or register it properly if attempted under different signals other than 5G or LTE...

well. define 'radio special menu' for me, I DID test with "preferred network type" set to LTE & 3G and that did not help.
EDIT: oh, you mean the *#*# #*#* type menu?

yes, although I have not been able to get the *#*#*#* method to work since the Pixel 2, but there are other ways to get to the advanced "Phone Info" "Set Preferred Network Type" option (although the *#*#* method may have changed/been updated and I just haven't tried it since...)

I was having this same exact issue just the other week. Unlocked P7P on Verizon and never had this issue on my previous P6P. I tried a number of things like resetting network settings, forcing 4G and seeing if it would work but I would still get the authentication failed message. I read on other forums and most of the solutions ended up contacting verizon and they would have to fix it on their end. I normally try to avoid contacting support but I ended up opening a chat with a verizon rep and they had me do the typical troubleshooting steps that I already did but nothing worked. After going back and fourth the rep asked me to restart my phone as he did something on his end but he didn't say what he did. After I restarted my phone it actually worked and my hotspot was working again. I used it a few days later and hotspot was still working but I haven't used it since and now while I type this I tried enabling my hotspot and I'm getting the same error again. I'm gonna end up contacting verizon again to see what's going on but I have no idea why specifically the P7P has this issue. I as well have been using unlocked phones since the P2XL and never had this issue. Hoping to get a permanent fix for this.

ok guys, issue is solved!
I took off work this afternoon and drove into town to attempt to acquire a new sim. I was told the wait would be 45-60 minutes, so I bailed and came back home. I then started up with Verizon support on chat after work. I was planning to ask for a sim to be mailed to me, but they offered to switch to e-sim, so I switched over to e-sim tonight and the issue seems to be resolved.
one of the multitude of techs tonight did tell me that she was having trouble ordering a new sim because there was some sort of conflict.
