So i finally decided today that i will keep my tuhunderbolt with verizon and drop sprint and my epic. I called verizon and got the porting process started to bring my sprint number over to my TB. The guy told me in about 4 hours to try dialing *228 and chose option one. Its been 5 hours now and whenever i try dialing *228 and hit call it connects for about 1 second then disconnects. I dont know if this is normal if the porting process isnt finished yet or if this is because my TB is rooted with BAMF 1.3 installed and im unable to do service programming. So will i have to unroot, do the *228 thing, then reroot?

you dont have to do *228 ever on a 4g device. it auto programs on boot
aslong as you got your number set up and verizon knows your sim number (18 or 19 digit number, something like that, dont feel like ripping mine out to verify). Just place the sim in your device and fire it up, as soon the phone powers up it should auto activate. You will know it is activated when you see a 3g or 4g system above the signal meter.. if it's still on 1x, try making a test call to voice mail (*86) and if that works and you hang up, hopefully your data will come around.
I would also call from a landline and see if prompts you that the user's voicemail is not setup etc... that will let you know if the number ported off yet etc. /edit
And if you are powered up, have 1x and make a test call and your line/sim is activated. **It can take up to 15 mins for your data connection to be active, so if your test calls work and you have no data, just wait a few minutes and it will come around.** /edit2

Thanks! Ill try rebooting my phone and see if that fixes it
magneticzero is exactly right. On a 4G phone the old *228 doesnt work. You might want to try rebooting the phone every so often and that should get your old number to pop-up.
I ported my number over to my thunderbolt while running a custom rom. I called gave them all my information. Was told that an email was suppose to be sent to me so that I can authorize the port. 45 minutes later I hadn't received an email so I called and was allowed to authorize it over the automated system which the call rep was on the line too. 5 minutes later a text was sent to my phone advising me that my number had been successfully ported. Had I just done the automated authorization the port process might have only taken about 10-15 minutes. I was never told to dial *228.
Just rebooted my TB and still dont have my old number yet :/ ill give it some more time, im just glad i dont have to unroot
I just saw the other part of your post magneticzero, they never asked me for the number on my sim, should i call and make sure?

nah they already have it when they shipped you your phone. i was just saying incase you bought the tb used and had to get a new sim, then they would need the new number.
Oh alright, i bought it brand new as a new customer thru amazon so they should know my sim number, thanks for all your help guys, hopefully they get it ported soon!

I had to remove my sim card, reinstall, and reboot, then it found my number.
I was told by Verizon never to use the *228 feature. Because *228 will fry the sim card. I get the feeling by this phone using a sim card they may have more access to what is going on with it. I guess I will find out soon. Since the first thing I did was root it and flashed a custom rom.

It's not that they have any more access to what is happening on your phone then they did before. What changed is the use of a SIM card instead of a MEID.
The reason that you cannot call *228 is that VZW has to run two very unique provisioning systems, one for GSM and one for CDMA and *228 is the access number for the CDMA provisioning system. Because of the fundamental differences in technology between the networks, on a GSM (LTE) network there is no need for a customer accessible provisioning system. Even if you don't live in a 4G area, your phone provisioning is still controlled by the LTE system on the back end.
Remember on all prior CDMA phones your phone was actually tied to the CDMA network via the MEID number that was unique to each phone. The purpose of *228 was to have the phone pull down all of the provisioning information from the VZW back end servers (I.E. your phone number and all of the other provisioning information that the phone needs to operate correctly on the network with your phone number). Because the MEID was unique and hard coded into each handset any time a change was made to the account the end user had to dial *228 to update the information on the phone itself.
Now (and this is why everyone who has been with VZW for any length of time is being thrown for a loop) with GSM service (LTE is a GSM service) you are assigned a unique Subscriber Identity Module (SIM card). This card contains a unique number, along with all of the basic information any LTE phone needs to communicate with the network, which is hard coded in the sim card you are assigned when you got your TB and this number is assigned to your phone number in VZW's back end system (just like your MEID was prior). There is no such thing as an MEID like you are used to in an LTE network. Everything is tied to the unique identifier on the SIM card, not the phone itself.
Your TB has no MEID. It gets all of its provisioning information every time it boots from the information stored on the SIM card. That is why dialing *228 does absolutely nothing, because there is no MEID on the phone for the provisioning system to read, and there are no settings on the phone it can update.
Welcome to the SIM card express train, population, everyone already on a GSM network. And for what its worth, SIM cards have been in use in the US for a long time now. In fact many of the problems VZW techs are having frying SIM cards because they are not handled correctly or activated correctly very much reminds me of when PacBell Wireless first rolled out GSM service (PCS as they called it) back in 1997.
Success! Thanks to your detailed explanation Nusince I figured out that it wasn't updating because I had turned 4G off and also changed to their old 3g network using the ##778# dialer code. After putting those two settings back to their stock setting and I rebooted BAM my old number showed up and I had 3g again. Then I turned 4G off and went back to the old 3g network that way my phone doesn't keep dropping the data connection and it's all smooth sailing. Thanks for your help everyone and hopefully this helps someone in the future.

my thunderbolt similar just went bad when switching between my thunderbolt and incredible. I did not hit *228 on my thunderbolt which makes your similar bad. the tech support Guy said once you activate another phone, the similar goes bad. is this true? if not l, what's the easiest method to do this?

My guess is he means Sim [card] and it's autocorrecting to similar
To OP: You're stuck, at least as it comes to your 'bolt, for the time being. You CAN activate another phone on your plan (like your inc) but the only phone on VZW that uses a sim right now is the 'bolt, so you will have to take it in and get a new SIM card, or have VZW send you one.
I don't have personal experience, as I haven't switched back from the 'bolt to a non-LTE phone yet.
So with the new SIM card, it is my understanding there is no need for activation anymore, correct? I had to have my first 'bolt replaced due to mic issue, and when I popped the SIM in the new phone, it just worked. I have never activated it. Any info if this is the case with all phones that will have a SIM. If it is I am so totally getting an Xperia play, if it has a SIM slot.

Right - the SIMs, as they stand, are interchangeable between 'bolts. No more activation or other things, but it won't work with just any phone - it has to be a Verizon network phone because the tech for 4G is different (it's not like when people could swap sims between ATT and TMo phones) - so, right now, since the Thunderbolt is the only 4G phone on Verizon, swapping SIMs will only work with other Thunderbolts
VZW explained it to me this way .... when going from a 4G LTE device to another 4G LTE device there is no activating anymore, you simply drop in your sim card. But, if you activate a non 4G LTE phone on your account that will deactivate your sim card and will require you to return to the store for a new sim card. This was in response to me asking them if I could switch between my Droid and Bolt.
For once VZW was very helpful in store. I normally don't go to the brick and mortars but being new to 4G I had questions I needed answerd.
The SIM doesn't get "destroyed" and can be re-used.. but... you have to call Customer Service for them to enter the SIM number...
here is what I did...
When I first got my TB, VZW was having network issues, and it took well over an hour for my "activate device" request to "clear the switch" and the TB to become active.
Having intermittent data issues over the next week, I decided to swap back to my INC, wait, and later return to the TB... I thought maybe due to the network issues, the TB didn't get all its programming info "over the air" or something.
When trying to return to the TB via the Activate Device link on the My Account web site, after entering the MEID/IMEI... I got prompted about needing a SIM... so I enter the SIM number and got...
"The SIM associated with the SIM ID you entered cannot be activated at this time. Please contact Customer Service at 800-922-0204 for assistance."
CS rep couldn't help... she had me on hold while she got Tech Support...
They had to manually add the SIM number back on the account.
Moral of the story... if you activate an LTE device and remove it from your account to use a 3G device.. you'll have to call back in and manually switch devices if you want to go back to using the 4G device.

The real reason you can't put your SIM in an ATT or Tmo phone would be the tech. ATT and Tmo use the GSM/UMTS/HSPA (3GPP) family for "2G"/"3G"/"3.5G" where as Verizon uses CDMAone/CDMA2000/EVDO (3GPP2). SIM cards are only on Verizon now that they're using LTE which is the next step in the 3GPP family but not quite 4G. Any phone made for AT&T or Tmobile is a "GSM" phone using the 3GPP family radios which are incompatible with Verizon's 3GPP2 network (towers). On top of that, they all use different frequencies. That's why unlocked iPhones can only use "2G" on Tmobile.

Were they able to re-add your sim to the account? I had a Thunderbolt which I traded for another phone, and switched to a couple of 3G phones in the interim. The Verizon store person told me my sim would be good for 90 days if I got another Thunderbolt. So I did, popped in the sim, and called support to switch over from my Fascinate to the new Thunderbolt. They got tech support on the line, and I was told that switching to a 3G device from a 4G device causes the 4G sim to be "retired" and that I needed to have them send me one, or go pick up one at the store. So the story was different from what happened to KidJoe and I wonder what your experience was.
A couple possible reasons why my situation was different: It was not the same Thunderbolt the sim was originally in. Also it's possible in playing around with the new Thunderbolt, I may have done a *228 just to see what would happen. Someone else suggested that would tank the sim.
I plan to go the store tomorrow and see if they can resuscitate my old sim, or if they give me a new one.
I had activated my thunderbolt when I got it with no problems. I decided to switch back to my incredible for a day and the sim was deactivated. Vzw gave me the run around between going to the store and calling customer service for a few days then they finally said they would have to send me a new sim because as soon as I switched to the inc my sim was "retired".

Yes. They were.
I did my switches only a few hours apart... (i.e. switched to INC, waited an hour, switched back to TB). And used the same phone and SIM. Not sure if that had anything to do with it.
There obviously is an inconsistency in VZW's system somewhere... the message you get when using "Activate Phone" on the my account web page to switch away from the TB says the SIM will be deactivated after 90days. But its being deactivated IMMEDIATELY. Either that message needs to be changed, or VZW's system isn't set up correctly.

Ok guys, I just got my sim and started service on Metro. Ive got data jumping everywhere. From EVDO to 3G to HSPA and then back to No Carrier Detected. When you install the Sim it sets up 2 APNs automatically. Sounds good but there has to be something wrong. If anyone has a clue by all means post away.

Hi, I was wondering if you could post the APNs from your phone to try because I have a BYOD sim also and I have no data and no apns in my phone. I called Metro and explained my problem about having no apns and spent awhile on hold. The lady first told me we had excellent coverage in my area, then put me back on hold and came back saying there was no data coverage at all. I told her I knew for a fact Tmobile has good coverage here and she elaborated that they do but metropcs has isnt able to access it yet or something? She completely glossed over me not having any apns set up. Does this sound right to anyone else? I'd like to give your apns a shot if I could despite what she said. Oh and I have a HTC One X, though I don't believe it makes a difference in this situation. Thanks!
I have metro through the Boyd program, first I started with a unlocked att gs3 and I took it to the store and they got it working with data right away, then I changed phones to the LG optimus g unlocked. Phone is beast! Anyhow, I called customer service to do a imei swap, I checked the list on metropcs.com and it wasn't on there. However, they were able to get service transferred to my new phone but data never came up. So I added the t-mobile apn and it works...4g and everything. Just thought I'd share my experience.

Hello all, so I recently consulted your fine website about purchasing the Optimus G to use on T Mobile here in Pittsburgh. It seemed to me that people were able to get HSPA+21 and LTE on the phone in the right circumstances, and that was good enough for me. So I bought the phone, unlocked it through cellunlocker.com and everything seemed to be going smoothly. I punched in the standard fast.tmobile.com APN address and I got 4G HSPA+ right away. I then proceeded to drive into downtown Pittsburgh, which now has T Mobile LTE, to see if it would connect. It didn't connect and stayed on HSPA. At that point I drove out of the city and went back down to EDGE and my phone no longer connected to HSPA anymore, only EDGE, until I went into my Mobile Network settings and selected the carrier directly. So I went into T Mobile to ask why my phone won't automatically connect to the most OPTIMUM speed and he couldn't figure it out. As a last ditch effort, we switched SIM cards and my phone automically jumped to LTE and his was stuck on HSPA. So hey, we figured it must be the SIM card keeping me from LTE. He gave me a new card, and it was on LTE until I left the store's broadcast radius. From then on, same story. The phone seems to pretty frequently get stuck on EDGE speeds and I contantly have to go and manually set the network to get HSPA+. What's more, I can't seem to get LTE under any circumstances. Can somebody out there please tell me what's going on? Do I have a defective phone with confused radios? Is T Mobile having a hard time syncing with my AT and T device? Do I need to do something with my APN or Mobile Network settings? Does this have anything to do with the way I unlocked the phone? Is it because the LGOG shares radios for LTE and HSPA or something that it won't default to LTE when it's around? I love absolutely everything about this phone and would like to keep it, but if it keeps behaving like this and won't even give me LTE or consistent HSPA+ then I might as well just get a crappy LG Optimus L9 that at least was designed for the network. Any insight you guys can offer would be much appreciated. Thanks so much!

Try flashing the 33-84 radio: http://www.mediafire.com/download/wec8eeext05x8ge/LTEhybrid33-84.zip
That's what I use to flash my LGOG. That's from the Nexus 4 radio thread, and from T-Mobile N4 devices. I was able to add a different APN for AT&T easily, maybe can do the same for your T-Mobile.
- Combines the latest .84 radio from T-Mobile N4 and .33 LTE support.
- The N4 Radio thread: http://forum.xda-developers.com/showthread.php?t=2087227
I see. Well seeing as I'm kind of a noob at this your post intimidates me a bit. How dangerous is it to put these N4 radios onto an LGOG? Will I risk bricking this thing or losing signal forever if I screw it up? Also, I'm assuming that the device must be rooted to do this? Also, if you think it's safe to try is there a thread or something that you can link detailed instructions for? I've never done anything like this in my life...I felt like a rebel just unlocking my phone! Thanks!

Not dangerous if you use TWRP. Just make a backup of your current stuff, and if it doesn't work can just restore. It won't hard brick your phone. And I've had it flash on more than one rom so far.
Root needed?

Help! I have the exact same problem. I have a brand new att lg optimus g and unlocked it. Popped in the sim and bam LTE! Ran a bunch of speedtests, drove to my friends house and it switched to 4g and hasn't come back. The guy at tmobile wasn't sure. ...any help ? I'm going to root this and try flashing a new rom...maybe radio?
Seems to be an issue with this device, perhaps it's doing something to the SIM cards (who the hell knows) because mine did/does the exact same thing, and here's my particular example:
When I first got this LGOG last Sunday (8 days ago) I put my T-Mobile microSIM in it (one of the TM9190 series SIM cards) and got LTE off the bat without any issues. I kept the stock ROM on here for the first day or so and never had any issues and then I got into doing the typical root/unlock bootloader/install recovery/backup stock ROM/flash custom ROM/etc routine and even after that I was still able to get LTE working almost immediately.
A few days ago I noticed that the LTE wasn't being picked up, and it hasn't since. I've flashed several radios for testing (.33, .48, .33-.84 hybrid, etc) and the ones that are LTE ready still didn't get LTE so I just flashed the whole thing back to complete JB stock (JZO54K, the last available LG build) and even that didn't help - I've yet to see LTE show up in any respect at all with that SIM card.
Now the interesting part:
I have another microSIM that had prepaid service a few months back, bought it at the same time as the one I use for my primary service - they were on sale from T-Mobile online for $.99 each so I got two and kept the other one around just to have it.
In spite of all the flashing I've done in the past few days, with like 5 ROMs tested, a kernel or two, and maybe 7 flashes back to pure stock using LGNPST and the LGE970AT-01-V20j-310-410-MAR-08-2013 ROM (the stock one), after all that flashing torture I put this LGOG through, as soon as I put that other SIM card in it - which is not active at this time - and powered up the phone I got an LTE signal right off the bat without a problem. Had already made the APN changes to fast.t-mobile.com so they just kicked right in and wham, 4G LTE right there on the status bar.
And yes, the SIM cards are the same "series" (?!?!) with TM9190 imprinted on both of them - they also have the same code on the front side (620048) and their serial numbers are just a few digits off in sequence - like I said, I bought both of them with the same order so, it stands to reason they'd be from the same batch.
Loaded a few web pages on the T-Mobile prepaid billing site (it's what comes up when you insert a prepaid already activated but not presently in use SIM, very limited but it does work), checked the system stats, everything showed me I was connected to T-Mobile with their LTE service, this phone, and that other SIM card including the status bar icon being the traditional 4G LTE one (big 4, little G, little LTE under it).
Then I rebooted the phone and that was that, the LTE capability just up and vanished like a fart in the wind, and I've done most everything that I could do - including reading a few hundred posts in two dozen threads - to get it functional again and it just doesn't work anymore.
I suppose it's not a big deal to me since T-Mobile's HSPA+ is fine with me, I regularly pull in 10-15Mbps on a speed test in various locations (was out earlier today testing stuff in the eastern parts of Vegas), but I am somewhat pissed that I am unable to get that LTE functionality working again.
Tried:
- a complete stock flash, several times, of the AT&T JB ROM, no dice
- all the currently available LTE-capable radios, no dice
- an AT&T SIM but it's not provisioned so it doesn't work at all (T-Mobile doesn't do that, hrmmm... their SIM cards work months later even after the number has been assigned to another customer, go figure)
- all the hidden menu options (3854#*970#, WCDMA automatic, tried forcing LTE only, several other things), no dice
- tried manually setting LTE only with *#*#4636#*#* using custom ROMs, no dice
- adding the LTE enabling lines to build.prop, no dice
Nothing works, so I'm only left to conclude that either a) T-Mobile is doing something funky (highly unlikely), b) something is borked with the phone (potentially true), or maybe c) the phone is doing something to the SIM cards after a reboot or any change in the network mode from LTE to anything else (leaning towards this possibility more).
I can't explain it, I can't figure it out, and I can't get LTE working anymore but as I said, the HSPA+ is enough for me as here at home the LTE signal is somewhat weak (1-2 bars at best whereas HSPA+ pulls in 5 bars and a -61dB signal almost constantly).
I wish I could figure it out because I'd like to do more testing with LTE enabled but apparently once LTE gets disabled for whatever reason after having it actually working, not once but twice now it just dies and never becomes possible again.
Stranger things I suppose...
If anyone does ever figure this fiasco out, post whatever solution you came up with or discovered so the rest of us can give it a shot as well 'cause I'd love to be able to enable LTE if I so chose. This is pretty frustrating in the long run - if it never ever worked at all that would be one thing, but having it work then suddenly just disappear never to work the same again, that's just pooched.
Slightly off-topic, but how's the battery life compared to AT&T? Or, in general, is it okay?

Seems to be an issue with this device, perhaps it's doing something to the SIM cards (who the hell knows) because mine did/does the exact same thing, and here's my particular example:
When I first got this LGOG last Sunday (8 days ago) I put my T-Mobile microSIM in it (one of the TM9190 series SIM cards) and got LTE off the bat without any issues. I kept the stock ROM on here for the first day or so and never had any issues and then I got into doing the typical root/unlock bootloader/install recovery/backup stock ROM/flash custom ROM/etc routine and even after that I was still able to get LTE working almost immediately.
A few days ago I noticed that the LTE wasn't being picked up, and it hasn't since. I've flashed several radios for testing (.33, .48, .33-.84 hybrid, etc) and the ones that are LTE ready still didn't get LTE so I just flashed the whole thing back to complete JB stock (JZO54K, the last available LG build) and even that didn't help - I've yet to see LTE show up in any respect at all with that SIM card.
Now the interesting part:

Thanks for posting your experiences. I've had the exact same problem, though I've never been able to get LTE working at all with my phone. I'm planning on taking a trip to a T-Mobile location within the next few days and see what they can do. Maybe they'll let me try putting my SIM in some of their display phones to see if I can get an LTE connection. Then at least I could probably rule out the SIM as the problem.

Make sure that your phone has the fast.t-mobile.com APN info in place (just create a new APN with that info if needed, maybe call it T-Mobile LTE and see what happens. My guess is if they put a new unused SIM into your phone it'll most likely kick into 4G LTE right from the start (as long as the APN is in place) and then at some point it'll switch to HSPA+ and it'll never go back like it has for those of us that have noticed it.
Who knows... it's probably just one of those things.

Could be...I've always had my settings on T-Mobile LTE, and I even called T-Mobile and confirmed every field in the settings with them. When I explained that I still couldn't get LTE, they had no other solution for me. The lady on the line didn't even know that LTE was faster than HSPA+, so I wasn't exactly expecting any sort of resolution. I think the reps in-store will be more suited to this type of issue.
I have an lg k8+ model x210ulm that i want to use with cricket. The phone is fully unlocked and will accept any sim from any carrier but has an odd behaviour that wont let me use my own sim.
I bought a feesh sim from cricket and when i put it in and set it up it will register with crickets apn and mobile network settibg. I get data and it shows up in the about network as connected and working. It shows cricket carrier in notificstion and i can get texts and even voice mail. But ........
I cannot use the dialer. Upon connection there is no error toast or anything it just imnedistely hangs up.
I can use my wifes my sons or my friends sims in the phone and after a reboot works perfectly. But when i put mine in it stops.
Also my sim works fine in any other unlocked device or cricket device.
Any clue as to wth is going on
Ok so after talking to lg and really that was frustrating. Why because the rep told me it the phone was carrier locked to us cellular which i knew it wasnt because its advertised as being unlocked and well us cellular put up an advert a few years ago stating that all thier phones are unlocked.
So after that i went ahead and talked to a rep at us cellular who assured me it was unlocked and checked the imei for me and sent me link to the advert about thier phones being unlocked.
Back to lg and got another rep this time who knew a lil about something but not much. Could not tell me any thing though.
Now back to cricket where we tested my girlfriends sim in my phone to which it worked and mine in her phone to which it worked. We put the sims in my aristo 2 and fortune 2 and both sims worked. But when i put my sim back in my my k8+(2018) once again every thing works fine but you cannot make or recieve phone calls.
We also tested the voice mail app and and thier what qualifies as a carrier app and it registers. The sim registers in about phone shows service and is connected. Shows the phone number every thing works.
Just not the phone Dialer app
So is there any one out there at all that has had an issue like this before. Any one that can help me figure out what the problem is. This is so crazy that my sim wont work and every one elses will.
Could it be something i did using dialer codes? Any cLues at akl
So here we are months later and im still having sim issues with my k8+ ulm. I ended up buying a brand new device and i tried my provisioned sim card with it not working but literally every other sim card works fine.
I have switched from cricket to assist wireless now who is run or what ever by sprint and i can get the sim card to work for a couple days before switching it to another phone but the main issue is that i get a error popup stating that the sim card has locked and that i need to power cycle and call customer service.
But i made a ton of changes by adding all the system apps from sprint including sprinthiddenmenu and any other apk that was on the tribute dynasty they came from. I also went through the file system and made any prop changes or any thing else that was needed to enable sprint.
At this point id flash a sprint modem but i cant find a cv1 device provisioned under sprint
