So I don't know what I was thinking, but last week while on the T-Mobile test run I tried to use the T-Mobile iPhone sim in my m8. I also tried using the VZW sim in the T-Mobile iPhone. Nothing worked. This isn't the problem.
After putting the VZW sim back in my m8, I no longer got 4G and my data connection kept dropping. This Sunday I spend 2 hours at the Verizon store trying to get them to resolve the issue. The idiot at the Verizon store tried to resolve the issue for over an hour using the original sim. After me begging him to stop wasting time and just replace the sim, the issue is still not resolved.
When he originally checked my phone in the database it was coming up as something like "Unknown device" which I'm assuming was caused by placing my sim in the T-Mobile iPhone. After replacing the sim, the IMEI and everything else seemed to be matching according to the guys at Verizon, but I still don't have 4G and data keeps dropping..
Any ideas?
I'm running a GPE rom so I'm wondering if I have to go back to stock to resolve this issue...
Probably need to flash stock recovery and do a factory reset from it. Might not need to fully flash back.
I had this same issue. I would love to fix it but I moved to a OnePlus One on T-Mo. I'd love to get this resolved though.

I have a very peculiar situation. A few weeks ago I called Verizon's prepaid department and started the process of getting month to month 4G data on my Xoom. When it came to the activation step on the xooms end, it kept coming up as already activated but wouldn't let me access any other page besides the activation page. The VZW rep said there was nothing else she could do for me. About a week later I was swapping the 4G sim card from my HTC Rezound into the Xoom and vice versa. Just for kicks, I powered on my rezound and to my surprise I was getting access to data on it with the xooms sim. Seeing as how the sim works in my phone and not the tablet, I figure that there must be some way to change the APN settings on the Xoom to mimic my phones. Does anyone have any suggestions?
Are you stock? If so root and flash EOS and see if it works. I'm curious about this.
I have the same problem I'm on stock rom I went to the verizon store I went through 3 sim cards and new line. Still will not activate . I bought it of someone who had it rooted before he sold it to me and returned it to stock rom. I updated it from 3.1 all the way to 3.2 and still no help. I going to ship it to Motorola to see I'd they can fix the problem.
i posted this on another website's forum yesterday...sorry for those who read it twice, but i got no responses and am desperate.
so my launch day phone had a bit of an accident last weekend the screen cracked. I was able to get another thunderbolt from someone, was originally a refurb (tag under battery says "remanufactured in Philippines" )
any who I've been using the refurb one for about a week now, no major issues. But now today I can't get LTE at all...I've tried reflashing different radios, going back to sense over CM7...nothing. Put the same sim card in another phone right next to it, LTE.
What else can I do? thanks in advance
Have you installed an app recently that is messing up the phone? Have you checked to see if LTE is active on the phone? *#*#4636#*#* and check your phone info. Could always try flashing another radio.
Why does everyone start flashing radios and performing hard resets on their phones when a signal problem shows up? Wouldn't it be wise to contact Verizon first and make sure it isn't their problem? If you haven't changed anything on your phone, there's a 99% chance that verizon is having an off day.
nothing comes to mind that i would of installed that triggered this.
tried different radios.
called verizon to see what they can do. Looks like I can get a replacement phone shipped out. Now to return to stock. thanks.

I'm surprised the VZW rep didn't tell you that it's because the 4G sim cards are paired with your phone. I tried to swap 2 4G phones on my account in the past and I was told that the 4G cards are associated to the phones and they would need to send me out new 4G sim cards. This was a while ago, so I'm not sure if it's still valid, but I would think that they'd have a way to re-link the sim cards on their end.
Good luck with this.
Yesterday, I received a new StraightTalk MicroSIM (ATT compatible) for my new Nexus 5. I have been using a StraightTalk T-Mobile compatible one that I used in my old phone. I activated the new SIM, using the automated phone system. This morning I saw that my phone still had no service. That is, zero bars, I cannot make calls or text. Of course data doesn't work either. I logged into my account and it said that the transfer to the new SIM is complete. So I called StraightTalk and was transferred 5 times to people who did the same trouble shooting with me every time. Their trouble shooting: power off your phone, take out your SIM and then start it back up. Then they said they need to send me a new SIM card.... Here is my issue, I feel like they don't know what they are doing so their answer is just to send me another SIM.
My question: Did anyone else have this experience or ideas on getting the phone to work? I've tried different APNs with no different results.
Okay, this is odd. I figured, since I won't have phone service for a while, I would root my phone. After I rooted my phone, everything works. I can make calls and data works. Not sure what changed but when the device was rooted, it also did a factory reset. After 50 minutes of crappy customer service, I think I'll just take the new SIM card they are sending.
Takes a while for them to activate it sometimes. I was with customer services for 2 hours trying to activate my Sim card because it wouldn't let me online.
Their customer service, signal penetration might suck, but it's way cheaper, which I'm good with.
Sent from my Nexus 5 using xda app-developers app
I wonder if maybe that is what happened but I think it probably had to do with the factory reset.
I do want to post one final thing since everything has played out today... On the phone I asked them to expedite the package since this is my work phone and ONLY phone. Today, FedEx delivered a new SIM card... it was the card only. No other packaging or information. It was the wrong SIM... I needed a micro and they sent a regular SIM... but at least they tried. After receiving the SIM today, I don't feel so bad about the situation. Things may have been different if my phone didn't miraculously start working. I would have had to cut down the regular sized SIM... to find out if it is an ATT or Tmobile version... it's probably the Tmobile versions, since I ordered the ATT version. Thats how things go... have a good day!
READ THE NEXT POST FOR CONTINUED ISSUES
*** I'm going to keep posting my experience, in case anyone else can find the information useful. ***
My service should have Auto-Refilled today. However, when I went to make a call, I found out my service was deactivated. I thought maybe Auto-Refill was disabled when I transferred to the new microSIM. Unfortunately, after spending another 45 minutes on the phone with customer service, I found out that they activated the replacement SIM that they sent me... the one that doesn't fit my phone and appears to be a Tmobile SIM. So, instead of just re-activating the microSIM that was working yesterday, they have to send me another one. I confirmed with them that they will be sending an AT&T compatible microSIM. We will see what I receive.
I've got a Verizon HTC M8 running DigitalHigh GPE 5.0.1 12/21 build, stock kernel.
I've had 4g issues with the phone since the first time I ever flashed away from stock. And the whole RUU back to stock and factory reset thing has never worked for me. The phone simply refuses to stay connected to 4G...
The first time I had the issue and I couldn't resolve it I called Verizon. Was sent through to tech support, who "opened a ticket" and told me I would hear from them once it was resolved. Never heard from them, but the issue did go away on it's own and the phone connected to LTE once more on its own. I was running BoneStock ROM at the time (this was back in August 2014).
Fast forward to November and I decide to switch to GPE and I start seeing 4G issues again. My phone would connect to LTE at first boot but once my Sim "activated" it would only connect to 3G from there out. I tried everything to get it back. I did RUU back to stock and factory reset, I flashed new radios, etc...
Finally I activated a new SIM that I had laying around and BAM! LTE service again.
... For a few days. And then back to 3G only.
I used an app called 4G switcher to force my phone to connect to a 4G signal and when I did that it showed that I was roaming... So I would dial *226 and update my roaming list and it would no longer say I'm roaming and would say I'm connected to LTE... For about 10 minutes and then back to 3G only.
I went to the Verizon. Wireless store today and they gave me a new sim and told me to call prepay customer service to see if I can get a warranty replacement. The new SIM instantly connected to LTE and has been connected for almost 6 hours now.
Is there something wrong with my phone that it keeps frying the SIM or could there be an issue with my account on Verizon's end, maybe something telling it to reprogram my SIM to not connect to 4g?
I have used my phone overseas for a month with a European SIM and a service that was only 3G, not sure if that would be relevant at all.
I'm fairly sure your problems aren't on Verizon's side. From reading over the thread, the GPE ROM certainly appears to cause some folks issues regarding LTE service. GPE wasn't designed to run on Verizon. It might be a good idea to stick with something built from a Verizon ROM.
Its a Lollipop thing. Happens on gpe, and Aosp 5.0 ROMs. Just wait till official gets out and they should figure out a fix.
Hey M8 crew!
New to the M8, just bought the phone from swappa. Apparently it has root/s-off/some lollipop build installed on it. Clean ESN.
Took it into verizon to activate it on my line, but the sim doesn't appear to activate as they expect. It detects that it was inserted, says to reboot, after reboot still says no service, and never performs any activation. Verizon rep was claiming that the rom was causing the failures, and it does appear to likely be software related if it is never launching the activation. VZW tech support was no help other than saying it may take up to 12 hours to activate the sim (bs meter going off). Spent 2 hours in the store trying to get it to activate, saying everything was fine on their end. Tried a couple sims in store to rule out a bad sim. Have even tried the tape on the sim trick to see if that might have something to do with it.
Has anyone ever seen / heard of this sort of situation before and have any idea of how to fix it?
Would a stock RUU flash help out in anyway?
Is it because it is not a verizon rom that the activation is not happening? Would I somehow be able to use a different verizon phone to activate the sim, then put it in my phone and have service start working?
Any ideas?

If the phone was used on another carrier it might be stuck in a non lte/CDMA mode. Flash stock vzw ruu. Do a factory reset. Go into mobile settings and make sure it's set to global. Then see if default network is set to vzw. Then check provisioning.
That did it. Thanks!

Np...bought an m8 for my dad a couple months back and same thing happened. I finally realized it was used on a different carrier.
