Bad network signal? Try a new 4G sim card. - Thunderbolt General

I have tried everything in the world to get my wife's Thunderbolt on par with mine. Out of the box, mine has worked like a champ, while she's on her 2nd phone. (Bad power button and 0-1 bars constantly.) Anyway, after getting home and looking at her replacement phone, I noticed the same issue, 0-1 bars. I thought to myself that there has to be more to this. I put her phone next to mine and I had 3-4 bars, while she had her usual 0-1 bars (74% time without a signal.) I thought to check the phones info under settings and bam, I found my problem. Software and everything was exactly the same, except our PRL's. Mine is 13004 and hers is 15008. So I immediately jumped online and Googled how to updated the PRL on the Thunderbolt. Apparently the PRL files are stored on the 4G sim card, and since *228 no longer works on our phones, the only option to get a different PRL is to get a new sim card. I checked the sim card that came with her phone and the date reads.....102810. I then checked the date on my sim card and it read....020411. So I will be going to Verizon tomorrow morning and requesting a sim that was made on or at least near the date that mine was produced and hopefully this will fix our problem. I will update this thread once I know for sure. So if you did this and it helped, please feel free to post your results. Also, when we swapped the phones out, we didn't get a new sim card since each card is tied to that specific number. The rep just put the old sim and sdcard in the new phone incase anyone was wondering. Hope this helps.
Update: Just left my Verizon store and as of right now, I didn't have to swap out my sim card. The rep checked and he said it showed that my wife's phone was under the regular nationwide network, while my phone was under the hybrid network.(Whatever that is.) So he sent out an network update to my wife's phone that should bring hers on par with mine. He told me not to turn off my phone because it may take a couple of hours to push through, but once it does, our prls or signal strength in our area should be the same. Once the update pushes through, I'll post the results.
Update to the update: After letting the phone stay on for 8 hours, got home, pulled the sim and battery out for 30 seconds, popped them back in and bam!!!!!! 3-4 bars of constant signal strength. Didn't have to change the sim card, but the PRL number did change from 15008 to 13006. (Which 13xxx means you're on the Hybrid Network.) If you're have a low to bad network signal, I would highly suggest you call Verizon or go into a store and have them make sure you're on the Hybrid network and not the Regular Nationwide Network. Have them send an PRL update/upgrade to your line and see if it helps. Worked like a miracle for my wife's phone.

I was having the same problem as your wife. Called Verizon so many times wasting my time talking to tech support getting no help. Then miraculously called one more time and the girl fixed it. No idea how though haha. I wouldn't be surprised if her problem has to do with her sim though.

I wonder if they can manually push the prl ota now..it wouldnt hurt to ask that too.

would love to hear an update to this, as my prl is 15008.
might bother the verizon rep at work about it see if they know anything.
At my house I usually have 1-2 bars, and i always thought it was because of coverage not being great here. If it is just a prl issue, hopefully we can get a fix!

From the looks of it there is possibly two prl and the 'older' prl isnt updating. Lets see i guess...

mine is 15008 and ive had no problems :S

Why am I not hearing any 13004 prls. Am I a rare case? Also, this might be device and area specific,but that 15008 is horrible in my area while my 13004 allows me to keep a constant 3-4 bars everywhere I go.

My prl is 15011 and have e bars of 3g in most places

Again they auto update with reboot. SO REBOOT YOUR PHONE IF YOU HAVE COVERAGE ISSUES!

And you don't need to EVER SWAP A SIM CARD ONCE IT HAS BEEN PROVISIONED EVER! Like all other GSM technologies the PRL with eHRPD (Verizon's CDMA LTE version) is AUTO PUSH being it's UPDATED AUTOMATICALLY. YOU DON"T HAVE TO WORRY ABOUT IT EVER!
The LTE PRL versions are DIFFERENT than the CDMA phone series. There is no uniform number because they are updated at different times with the IMSI on the SIM card.
Also the signal meter on the Thunderbolt I was told that is mainly for VOICE! You can have EXCELLENT DATA on LTE with even 1-bar of signal.

Yes, that's what I'm writing about, voice service. And no, its not auto updating. Even after a battery and sim card pull for 30 seconds, its the same PRL number with the same signal problems. Average of -104 - 107dbs, which shows 70%+ time without a signal. She drop calls and her voice calls are in and out. This is her second phone, with the same signal results. So its not the phone and its not auto updating to the towers nearest to our house.

After reading this thread, I checked out my PRL version. For some reason, I have never received a PRL update. My PRL version was 1. I have rebooted my phone several times, along with battery pulls, for the past week yet no update was received. I ended up using the method mentioned over at Android Central (h ttp://forum.androidcentral.com/htc-thunderbolt/72724-problems-3g-data-dont-hard-reset-read-first.html) to put my phone back to RevA for data. I rebooted and still no new PRL. I put it back to eHRPD and rebooted. I then received a new PRL, version 15008. I don't know if it has made a difference with my coverage because I just made the change. I just figured I would mention I had to do some trickery to get my Thunderbolt to pull down a new PRL.

Thanks mispes1 for that info on what you did. I found this thread because of my Signal being weird. I just got my Thunderbolt activated yesterday and my prl was also 1. Used that thread and rebooted a few times, and after switching back my PRL finally updated. I'll have to see if this helps. It's nice to know how to switch to normal 3g network as well for when I'm having trouble with the hybrid one. Also my PRL is 15011.

Just checked, and mine is 13004...I wonder if this chagnes based on if you are in a LTE network area or not

I am have 15008 and my connection is terrible. I have done battery pulls, everything trying to get my PRL to update, might call verizon at some point and ask about it. I see people with these 13000 something PRLs talking about great coverage. I am at -86DB and my connection to 4G goes in and out all the time.

15008 as well here, but I haven't really had too many issues, the only times i've had issues is going inside large buildings around the 4G edge. Though my speeds haven't been too impressive (Fastest I've seen is 8Mbps on 4G), though I don't know if a PRL will fix that.

I must have had a different PRL before i rooted, cause I was doing 20-30 consistently down, and then I rooted my phone and now I get 6-7 consistently.

I have the same problem pulling down PRL updates. I realized the other day that my version was 1. To get mine to update I had to use the ##778# trick and put the modem into Rev A, reboot, then back into eHRPD, reboot again and then it pulled down a new PRL. The funny thing is that I have jumped between 1 and 15008 at least twice in the last 24 hours and there doesn't seem to be any rhyme or reason as to why.
Give this a shot though to see if you can get a new PRL. Also, I believe the most recent version is 15011. My friend got his t-bolt today and that was his version out of the box.

Widget turned off 4g/3g, can't turn it back from 1x

So I was playing around trying to delete widgets and one of them took out my 4g/3g connection. The icon is stuck in 1x, and I can't find any setting to change it back.
dail *#*#4636#*#* . This will take you to the network settings. select phone information. And then scroll down to set preferred network type.
I did that, set it to both LTE mode as well as CDMA+LTE/Evdo, but then even when rebooting to toggle it, it shows Network Type as CDMA - 1xRTT
I'm seeing other threads with people having issues with being stuck in 1x, so maybe its just not me, and I disconnected and just happened to not get it back
I am having this issue as well. Rooted last night. In the process of removing system apps removed something I shouldnt have. Went to flash my back up created by Rom Man only to find out it wasnt made, fail, so i flashed the custom rom by Chingy. Since flashing the rom I only have 1X service no matter what I set the phone to on the toggle.
its not just you bro ive been having 3g and 4g problems all morning. I am in queens NY...if they dont get this fix before the 14 days I am returning this phone and going back to t-mobile
I had thus problem. Just turn airplane mode on for a minute, then turn it off and you should get 3g again.

I'm not even rooted, and I began experiencing this issue this morning after having my phone off and plugged in last night.
EDIT: I tested the above fix, and it didn't work for me. Every time the phone tries to turn 3g on it will appear in the status bar for a split second and then everything turns off, even 1x. weird.
It's a network problem on verizon's end. I'm in Cincinnati and data is not working at all.
I am getting this too - according to tech support, there is a problem with the 4G network right now - however why it doesn't fall back to 3G I don't know (unless there is a problem with that too).
I too am in New York, so it might be localized to NYC - They even tried resetting something on my VZ profile.
I'm still on the call as we speak, but I get the feeling given the number of people reporting this, it is a VZ problem.

It's definitely not just a localized problem. I'm all the way out in Utah (no 4g service here yet) and the 3g is completely jacked.
Yup confirmed with tech support, there's a nationwide outage with 4g data and they are working it with the highest priority, the tech said. Ah the costs of new technology. Always will have issues at start.
Same thing here, Pensacola, FL. Just went out on my drive to work today, now it's 1x across the board for me and the gf...she has an incredible and I have the tbolt...
Add me to the list. Been on the phone with tech support for 52 minutes and counting. I'm on hold right now and thought I would check xda. Stuck in 1x if I even have anything. I am about 35 miles south of Pittsburgh, PA. Phone is completely stock and worked perfect yesterday. Also, the tech said DO NOT dial *228 from the Thunderbolt. I didn't, but he said for future referece it will force the phone to use only 1x and 3g. Nice to know lol they didn't say that crap when I bought it. At least their tech support guys are super friendly.
Weird. Im in Akron Ohio and have full bars 4G. Just did speed test and getting 15Mbps down 20 up. Downloaded app off market just to be sure and downloaded without a hitch. This must not be affecting whole nation. (Yes my Wi-Fi is off lol)
Just got off the phone with VZ Tech support. He said there is not an acknowledge problem with the 3G network right now (unlike the 4G), but he's sure that soon there probably will be.
He could not use my phone as an example case (to raise the trouble ticket) because I was unwilling to perform the last step in the troubleshooting process (reflashing the phone) - but I'm sure there will be others willing to do that and this will become a known issue soon enough.
Worst part is, even my 1X support keeps going in and out - probably because the 1X network in NYC is overloaded, because all those users usually on 3G are all on 1X now, and killing it
Confirmed here, too...all 1x, must be a nationwide 3g issue
Same here south of Chicago. Guess I won't even bother calling about it. Thanks for the info.
This is definitely a widespread issue... I am in Miami and I can't even gey 3G here... I am only getting 1X.. The weird thing is, my friend has a Thunderbolt too and she seems to ne getting 3G fine.... If anyone receives any worse from Verizon, please post ASAP!!!
Yup im located in Manhattan New York having the same exact problem since 8:30am today No 4G or 3G i hope they get it fixed Soon Let's Go Verizon!

[Q] no LTE

I have a verizon gs3 that is rooted, running beanstalk 4.4.251-20140301-d2lte. I can't get LTE to work correctly. I can get LTE to turn on if I change my 'preferred network type' to LTE/GSM/WCDMA, but then I have no verizon signal (voice signal). When I have it on 'global', I can get 3G and verizon signal, but never any LTE.
This has been going on for quite some time. I've switched between all of the 'preferred network types' but its always 4G and no cell signal, or 3G with cell signal. I used to be on CM 11 nightlies, thought that might be the issue. I switched to Beanstalk, but have the same issue. Just yesterday, I updated my firmware from here: http://forum.xda-developers.com/showthread.php?t=1788313
Is there something obvious that I'm missing?

I have the EXACT same issue, so you're not alone! Unfortunately, I have no answer for this either.
I was running CM11 (just the stable releases), started noticing lack of LTE a few weeks ago, decided to give SlimKat a try. The ROM is damn near flawless besides this LTE issue. I could actually never get it go into LTE mode through the normal settings, it would always fall back to 3G (and I'm in the middle of a capital city where there's plenty of 4G coverage). However, if I did that *#*#4636#*#* trick to go into testing mode, I could force it into "LTE Only", at which point the phone would be in LTE mode, and enjoy the blazing fast data speeds I pay for .... but can no longer make phone calls.
Anyone else out there experienced this or something similar? Any suggestions would be greatly appreciated.
Thanks!
After doing some research on it, I decided to flash back to stock and unroot. After that, I still could not get 4G, so I took it into the verizon store. I told him the problem, and that I had heard that it needed a new sim card. After doing some simple test, he burned a sim card for me and that did it! I'm thinking that soon after I flashed a CM11 nightly (a month ago at least) I dialed *228 to update my cell coverage. I think that might have fried it. I have limited knowledge on this topic, but I did read somewhere that dialing *228 on some custom roms is not good.
It would be nice if you could take it in to the store without flashing back to stock, but I'm not sure if they would go for that or not.

Loss of 4G?

I've been trying to troubleshoot this problem for the past 3 days or so. In a nutshell, I'm on AllainceRom (which I have been since released) and get constant 4G signal. Wake up, head to work and notice no signal at all. I check and my mobile data was shut off, so connected it. It gets a connection...3G. Turn on/off airplane mode and still 3G. Borrow friends sim card, boot it up and it's 4G. Figuring it's the sim card, I buy a new one. Call Verizon to activate it, BAMM 4G is back. Within 2 minutes after the phone call, it loses signal, then kicks back on, 3G again. I would hit airplane mode on/off and 4G would pop out and all of a sudden it would go back to showing nothing,then revert to 3G again. Any ideas of what can cause this? I'm baffled. I even downloaded the MF1 versus ML1 and it still shows 3G. My download speeds, a blazing 2 megs. Almost feel like I've been throttled or something for some reason.
Has your phone been working fine before and this just started happening over the past few days? Also do you only lose 4G in certain areas?
I know that it is recommended to flash the ML1 modem on any 4.3 based ROM because of potential 4G issues.
This might sound odd, but I think somehow they are throttling me. I'm on the grandfathered unlimited plan. What's odd is that I can take an old sim card (from Thunderbolt), basically cut it to the same size as my S3, reboot and 4G is constant (this phone is part of my dummy line so limited to 2gigs per month). Take out that card, put in new one, it boots up and has like 4 bars while searching for signal, then drops to like 3 and connects to 3G again constant.
4G has been constant here for the past 2 years, Verizon tech support confirmed no outages. My wife and son have unlimited as well, but iphone 4's with 3G coverage. Thinking my unlimited 4G is getting knocked down for some reason.
I tried a new rom, Clean Rom and same results with signal quality. Just odd it happening all of a sudden with no changes.
Also, with my thunderbolt 4G sim card, mobile network type was listed as LTE. With the brand new sim card they activated, it's showing "CDMA -eHRPD", as it was showing with my old card.

I doubt you are getting throttled. Unless you are using up 100+ GB a month constantly. If that was the case you can call tech support and ask if you are. I'm pretty sure they would have to tell you if they were.
Was there something specific you did to your phone before this started happening? Have you tried different ROMs or re-flashing Alliance?
If you've exhausted all options I think something is borked and you need to reprovision. To do this you would need to ODIN to a stock 4.1.2 base and enter the reprovision code into the dialer (*2767*3855#). This will wipe your internal data so I would back up anything you need first. Once you do that you can re-root and flash a custom recovery then flash back to whatever you want.
Just make sure you don't take the 4.3 OTA if you return to stock unless you want to re-lock your bootloader.
That's the odd thing, nothing was changed prior to this switching to 3G, like it happened all of a sudden. I checked my usage and I'm at 19 gigs this month (yeah I tether a lot).
I tried beanstalk rom (4.4.2) and something odd happened. In preferred network type, under CDMA+LTE/EVDO I would get 3G. If I switch it to LTE/GSM/WCDMA 4G would pop up, but no mobile data so unable to make phone calls. With this rom, I would insert my old thunderbolt sim card and 4G all day long again with no issues.
I guess the only option would be to revert to stock and start all over in hopes it'll switch back. I was hoping it was just the icons jacked up, but at 3G my d/l speed was 2 megs, at 4G it would hit 12-14 megs.

If other SIM cards are working correctly, it can't be anything wrong with the phone. I would either go to Verizon and keep asking for new SIM cards until you get one that works, or try to reprovision like I explained earlier.
Thanks for the suggestions, I'm rocking stock 4.0.4. now and still only have 3G service. Guess I'll just keep it like this and hit up the Verizon store and have them figure it out since it's stocked back out.

I was experiencing similar issues as you this morning. After an hour of the nice lady at tier 1 tech support telling me to erase everything on my phone and that it was probably bc I was talking to her on the phone while trying to fix it I reached a resolution upon calling back. I was sent to a higher tier tech support and they told me that my data was being throttled and it was directly related to my high data usage.
Confused I asked her how that was possible bc they aren't suppose to throttle LTE. She said there is a problem with their system and instead of only throttling 3G, it was now throttling LTE data. She explained this is a nationwide issue and that some people she has talked to have been experiencing trouble with this issue since March 23rd!!
Similar to you I tried another phone, my nexus galaxy only to experience the same problem. The only thing that worked for me was switching my network mode from LTE/CDMA to Global. I could then tether Netflix and use the data connection without being impeded. However, certain functions like my email (gmail and yahoo) and verizon cloud services would say network error or network communication error.
Strangely tonight my phone seems to be back in working order, I'm not sure if its just because there is no network congestion so I'm not being throttled and it will return or if the issue has been actually fixed.
Now that I think about it, it's possible the tech was wrong and it's a CDMA to lte handshake issue they are having which would explain why global mode would work? It maybe that they upgraded the towers to lte advanced in my area causing these types of issues but hard to confirm any of this with verizon being so tight lipped about what areas have lte advanced.
Replied to your post, I'll update once I get back from Verizon.

Terrible signal!

So my phone has terrible signal now ever since I got home from college. I remember it was sorta spotty where I lived but never this bad... I have around 40% time without a signal! It's so bad I can't even text... My messages just don't send half the time. I got a new Sim card only a couple months ago so I feel like replacing that won't help.
I checked my mother's phone and she has the same prl version which is 15287.
Her mobile network type is is set to global and on the status page displays: cdma - even Rev. A, while mine on the same settings displays just LTE for the network type.
I keep bouncing back and forth between global and LTE/CDMA the past couple months, im just going to leave it at global and see if it gets better here... Any sure way to load all the defaults?
I feel like my phone is just getting too old, I've got my upgrade in August but do you guys have any suggestions on how to make my signal better? Also what is the default network type for Verizon I thought (was told in the past) it was LTE/CDMA but when I checked my mother's phone it was set to global?!

So my phone has terrible signal now ever since I got home from college. I remember it was sorta spotty where I lived but never this bad... I have around 40% time without a signal! It's so bad I can't even text... My messages just don't send half the time. I got a new Sim card only a couple months ago so I feel like replacing that won't help.
I checked my mother's phone and she has the same prl version which is 15287.

I've been having recent issues in my area too. Seems to have started when my PRL was updated (15310) or potentially it is my sim (which I also replaced recently).
In any case, this is what I did to try and resolve it

It now switches correctly to 3G when there is a 4G signal. However, you SMS messages should send regardless of whether or not you have a 3 or 4G signal. MMS will be an issue though. As far as whether it is on Global or LTE, it won't make a difference in reception. You'll have better battery life on LTE/CDMA than on global as there is no need to have the GSM radios active if you aren't using them.

Hmmm thanks for the information! It seems like that could be what is happening to me. But weird enough typing *#97328640# in the dialer doesn't work?! It just says call could not be completed!
I hope this problem doesn't carry over when I get a new Sim / phone.
Also is disabling -eHRPD a wise thing to do? Also I left my phone on global and it moves to -eHRPD and I have good signal but my texts still arent sending for some reason but then it switches to CDMA 1xRTT and thats when im able to send texts but constanlty switches to Unknown/ no service and then after no serviece for a but back to -eHRPD?

Shield LTE on T-Mobile issue.

Just got my Shield LTE today. This is my first tablet ever as well as my first unlocked device ever so I've never really had to mess with APN settings before. Long story short, I can connect and get HSPA+ ok but the speeds suck and no LTE at all. My Galaxy S5 can pick up LTE fine and get around 50Mbps down, but the Shield gets only about 5 down on HSPA+. When I search for network operators, my only choices are T-Mobile (2G/3G) and AT&T (2G/3G/4G). Any ideas as to why it can't find T-Mobile LTE network?
Does your phone work with LTE in the same spot? I got my tablet yesterday and moved the TMO SIM from by iPad to the Shield. Got LTE right away without doing anything with APNs. Depending on where you are, TMO LTE coverage is spotty.
Yes. My Galaxy S5 gets about 3 bars on LTE while sitting right next to my tablet that only has 2 bars on 3G. Just got off the phone with T-Mobile and they said they could see me connect to the LTE network and I did see LTE come up on the Shield for a moment but then it almost immediately dropped back HSPA+. I think its an issue with the tablet itself. I'm on hold with Nvidia now.
I'm still trying to get my Shield LTE activated on T-Mobile for the 200 MB free data for life deal. T-Mobile told me that their system saw the Shield's IMEI as a phone, not a tablet, and to bring it into a store so they can see that it is indeed a tablet.
The APN Settings came down by default for me and appeared correct with what I've searched online, but I'm having the same issue where I'm not getting LTE here in the PHX market, in all the places my phone gets full healthy LTE.
I don't want to complain about my H+ signal, but it's just not cutting the mustard if you will.
You find/hear anything useful here Hoju?
I'm seeing the same issue With LTE/Tmobile alsnly HSPA+
I've been in contact with Nvidia support since last week and they have had me send them numorous diagnostic files and bug reports. From what I can tell, the Shield is using NVIDIA
's Icera i500 modem which can be thoroughly tweaked through software updates. I'm hoping this issue can be resolved with such an update. Nvidia level 2 support told me that I was the first case of this reported, so I urge everyone suffering from this issue to contact support so they can see that the problem is not an isolated incident. I'm hoping to hear back from them today regarding this. I will update the thread when I do.
T-Mobile setup my imei number as an iPad to activate sim and didn't give me the pin, called T-Mobile and got it fixed, the pin turned out to be 1234, once he fixed the imei and changed pin, internet started working well and LTE is working as well. Also logged into T-Mobile.com/connectme I'm not sure if that's required but that's where you can buy more data. Hope that helps someone
Hi there, T-Mobile retail dealer here. I've tried 4 different T-Mobile sim cards (2 $50 simple choice plans, 2 $70 simple choice plans) along with 4 of their MVNO's sim cards (Univision Mobile, Straight Talk, Ultra Mobile, Lyca Mobile) and they all had LTE.
With all of the T-Mobile sim cards, the standard APN that's loaded in (fast.t-mobile.com) works perfectly for me.
For the MVNOs, using their respective APNs allowed for LTE, while using "fast.t-mobile.com" on those services only gave me HSPA+
I'm also located right outside of Philadelphia. Not really a populous area but we have good coverage with T-Mobile around here.
Hope this helped.
I also just added ro.ril.fast.dormancy.rule=0 to my build.prop, result so far is stable connection on h+. Without that it was flipping between 3g and h+ constantly and connection was unstable. ive been streaming music and it did change back to 3g, but not back and fourth like before, ill keep an eye on it.
maybe i spoke to soon, i still see it switching. Ill update after some more testing if this did anything or not for me.

Just out of curiosity have you noticed a difference in the last three days overall?

Not really, guess it was a placebo effect at first and just happened to stay on h+ for a while. from what i have read over the last few days is that on t-mobile's network it switches to 3g to save battery. I just removed the line i added, streaming music right now and just got a drop out. If someone knows or comes up with a way to force it on h+ I would happy, i could care less about battery savings if i just have this thing on my desk plugged in all day.
I got some time today, going to try staying off of wifi all day and see how it acts, might try a couple things if i can find some other options to test. if i find something ill let ya know.

Thanks for the response. I ended up exchanging mine with a new one that I just received last night. Right now I'm still testing and hopeful it will shape up, mine would drop from H+ to Edge, I do get LTE from time to time but it's very sparse. So far the replacement is doing well but i'm more and more convinced this is a radio issue as the tablet was really certified on AT&T. I've filed a ticket on my old one with Nvidia, no eta on a fix. Anyone that's seeing this go through nvidia support and file a ticket. Hopefully they can get it fixed in the next OTA.
I, too, only get H+ signal from TMO on my Shield. While it's normally fast, it sometimes drops and goes to E(DGE) or none at all.
EDIT: TMO could find nothing on their end via online chat. I'm going to test the SIM in another LTE device, and see if its a SIM issue. Waiting to hear back from NVIDIA. Really hoping our coming-soon 5.0 update fixes this!
EDIT 2: I just heard back from them that the TMO issue is an open bug "and will be fixed in a future update".
shield vs lte?
Yours at least connects, mine wont even do that I probably go to local branch again tomorrow if things wont change by the morning. I hope it works, but i cant activate the sim. Shield recognizes the card, under connections it says T-mobile but every time i turn off WiFi and try to activate the sim via cellular data, it keep telling me theres no connection yet i have 2 bars of their signal
So this means that I could but the 30 dollar a month plan? 5GB data, 100 minutes and unlimited texts?
Did anyone that was having a problem with LTE ever get it resolved? I just picked up the LTE version of the Shield tablet and have yet to see LTE and my phone is getting it fine. I hope a solution was found.

Yep, I'd be interested as well. I got that tablet since a few months and have problems with the radio too. I'm running LingeageOS 14.1. The latest few builds didn't even find the sim card anymore. Today I got back to stock rom for testing. Sim card is there, but it loses the radio connection every few seconds.

I just tried T-Mobile: works like a charm. It seems like Vodafone is causing the trouble. I've tried two different SIM cards and have the problem with both. Country: Germany.

What LTE band is your phone connecting to? I'm assuming you are T-Mobile? If you're in a band 12 area you might be out of luch as the North American version supports bands 2, 4, 5, 17, 7.
