I'm posting this as a new thread because of all of the answers that contradict my experience in similar threads. I took a Verizon SCH-I535 set to 'global' to T-Mobile to have a GSM SIM put in. Even the Verizon customer service said that switching to a GSM card would work as the phone is not locked.
I also took an SCH-I545 in and switched SIMs without any problem. The APN data was reset automatically and my old number was ported over to T-Mobile. All was good.
However, when they put the T-Mobile SIM card (and we tried 3 different SIMS) in the SCH-I535, the T-Mobile APN entry showed up, but the T-Mobile network won't recognize the SIM card. Since they had also transferred the number from Verizon to T-Mobile, even returning the Verizon SIM card is useless. The phone can't make or receive calls on either network. I don't think I can get Verizon to reset the number back to Verizon even temporarily since I am a couple days past-due on my bill and VZW won't give you ANY help until you pay past-due amts (won't have the check for a week ).
Any suggestions? I need an exploit to break the "non-existent" SIM lock so I can return the T-Mobile SIM to the phone and have it recognized.

Have you tried changing the apn settings? It may be defaulting to the VZW network

Thanks for the response, but I called T-Mobile's tech services at 611 and (unlike years of dealing with VZW doofs with technical IQs approaching that of a stale Cheez Doodle) immediately got a highly knowledgeable techie. When I was in the store and the SIMs they tried didn't work, I pleaded with them to call tech support, but they insisted that it was the phone's fault since they tried multiple SIMs. Seems that, when T-Mobile (or at least this store) breaks a SIM out of its cardboard holder, but doesn't actually sell it, they simply tape the SIM back to the card and consider it cherry. When I got home and called the techie, he had me read him the SIM id and it turned out it had been tried out before and was still associated with the other cellphone (probably true also with the other "recycled" SIMs they tied. I read him my APN numbers and it turned out that the only problem there was the original name, which should be "T-Mobile" (it was slightly different).
He got the store's number from me, called somebody at the store, told him exactly what to do to get the phone working, and told me to go back within half an hour to get a brand-new unsullied SIM. I edited the APN name, he put the SIM in and - voila!
The onlyl problem I'm having now is that, though I was able to set up my T-Mobile mailbox for my Galaxy 4 with it automatically defaulting to a long-press of key 1 (or dialing 123 and hitting the call button), on the Galaxy III, the mailbox was set up, but a long-press on key 1 calls the non-functioning Verizon voicemail, and there is nothing in the stock system to allow you to edit the quick-dial assignment for button 1 (yes, I removed the Verizon voice-mail app and stuff down at root level). So, I set up button 2 to quick-dial 123 and now button 2 is my long-press voicemail button. Weird - I need to dig a bit more into the innards and find a way to clear the first button assignment - maybe set in build.props???
So, the phone was not at fault and T-Mobile's tech department was a revelation in totally unexpected competence and depth of knowledge (unexpected after 26 years with VZW), but the three people who mucked around with the phone at the retail store are not only proof that we descended from ape-like ancestors, but that many of us are still descending .
Thanks again.
I seem unable to get LTE on my D850 since I installed CM12.1 and was wondering if this is common for this ROM. I installed the nightly, so I assume its obviously going to be a bit buggy, but to not have LTE working seems strange.
I checked my APN and I tried both ATT LTE and ATT Phone. The ATT LTE gives me a status bar with an exclamation point and never establishes a data connection and ATT Phone gives me HSPA connectivity. At one time, I waited a few hours and it eventually established LTE but that was an uncommon occurrence and its never been repeated since.
With other ROMs I have not seen this issue replicated. I tested on Cyanide L, Euphoria, and the Stock LG ROM and everything worked fine. Any suggestions?
Hey there,
I'm running CyanideL myself, love this ROM.
Which nightly version are you using?
Have you checked that Mobile Networks --> Preferred network type.... is set to LTE?
Have you tried toggling to 3G, getting a connection, then moving back to LTE?
I also have this problem. Has a solution been found?
I just ditched the stock ROM and installed CM12.1 a few days ago. Now LTE has disappeared. I had it, now can't get it. I'm not able to select LTE in the settings→Mobile networks→Preferred network type menu, nor can I select any option that includes LTE in the test menu (*#*#4636#*#*). It's probably some stupid user error, but whatever it is has been eluding me for a day of messing with it.
Presently running cm-12.1-20150804-NIGHTLY-d850.

Interesting...
Have you tried restoring your stock ROM and seeing if it will connect? How about a SIM card pull?

Thanks for the reply. I have not tried returning to the stock ROM. I just got all my apps reinstalled and data restored, widgets installed, screens set up, etc., so I'm not too keen on doing all that again so soon.
I have tried a chicken SIM card pull. I was somewhat fearful of doing a pull "hot" as is usually suggested. I powered down, removed the SIM card, and restarted. After restart, I was able to select LTE in the settings→Mobile networks→Preferred network type menu, and the test menu confirmed that LTE/GSM auto was the preferred network type.
I then powered down, re-installed the SIM, and restarted. After restart the preferred network type had been reset to 3G and I was (am) unable to select LTE.
My conclusion is that this is something to do with the Net10 SIM I'm using. I've ordered a new SIM from Net10. The Net10 rep says a new SIM may fix things. One is on it's way and should be here in a few days. I'll post the result.
[SOLVED]
My new "LTE capable" Net10 SIM arrived today. I had Net10 customer service transfer my service to the new SIM. Now I have LTE; I'm able to select LTE in the Settings→Mobile_Networks→Preferred_Network_Type menu, LTE appears in the CM12.1 status bar, and I'm able to make a solid LTE connection.
I will here piece together everything I've learned from my own experience, Net10 customer support, and internet searching. My conclusion is that there are TWO compounding problems for Tracfone/Net10/StraightTalk users. One is techhnical and the other is marketing.
The technical issue is that all Net10 (also Tracfone and Straight Talk) AT&T SIMs sold up to a couple of months ago don't work with LTE on the AT&T network. That's most of the AT&T SIMs from these companies out there in the world today. This is not widely known – in fact, most of the Net10/TF/ST customer service reps are not aware of it. It's not something that Tracfone and its subsidiaries want known because it would cost them a bundle replacing SIM cards for unhappy customers. If you have a Net10/TF/ST SIM that's more than a few months old, you have to call Net10/TF/ST and buy another new one that's compatible with AT&T LTE if you want LTE service.
So, why don't more Net10/TF/ST AT&T users raise a fuss and demand LTE capable SIMs? That brings us to the marketing issue.
AT&T lies. So do Tracfone and its subsidiaries. AT&T markets its HSPA+ 3G service as 4G when it's not. In fact, the AT&T stock ROMs that most people are using lie. The stock ROMs display 4G or sometimes 4GLTE (depending on ROM version) in the status bar when in fact it's a HSPA+ connection; not 4G let alone LTE. So users cruise along using their old SIM cards happily thinking they have 4G or LTE connections when in fact they do not; and they're none the wiser. It's only more sophisticated users who flash a 3rd party ROM, one that doesn't lie, who figure it out.

Hello. I'm trying to get FreedomPop service on my Nexus 5 I got from Google Play a while back and have been using it mosly with Virgin Mobile, which is a GSM/LTE carrier (Bell's MVNO). I tried going through the FreedomPop's BYOD wizard, put in my IMEI, it told me there was a problem and instructed to call an 1-800 number. I did that, and the rep on the other end seemed to have been able to create an account and activate it. She told me to wait 15 minutes and powercycle the phone. I asked her specifically about a SIM card, and she told me I didn't need anything and that they don't use SIM cards.
I waited 15 minutes, powercycled my phone, but didn't get any service - the phone has the "no sim" icon, all network settings are greyed out because of that. If I got to the testing menu (*#*#4636#*#*), under the phone info the preferred netowork type is LTE/GSM auto (PRL). I tried switching to CDMA, LTE/CDMA auto (RPL), LTE/GSM/CDMA auto (RPL), but as soon as I go back and to phone info, the setting is back on LTE/GSM auto (PRL).
I've searched all over internet and couldn't find an answer about getting service. Most posts are about the other way (FreedomPop's phone to use with GSM carriers like TMo). Any ideas what I'm doing wrong? I wanted to ask on FreedomPop forum, but it seems you have to wait until your new forum account is approved by a moderator to even be able to PM/post/reply.
If anyone could please clarify the whole story behind Nexus 5 on Sprint/MVNO networks, whether SIM/UUIC is/is not required and how to force the phone to switch to CDMA mode, I would be really grateful.
Ok. Looks like the rep that activated the phone was not competent. She told me I didn't need a SIM (UUIC) card, which in fact I did. I got one from Sprint. This was yet another challenge, as if I told them I needed one for Nexus 5, they were saying they don't carry that phone, and don't have SIM cards for it, telling me to go to Best Buy, which wanted to charge me $30 for it. When I told them that I needed one for Galaxy S5, they surely enough gave me exactly what I needed - SIMGLW206R
I plugged in the SIM, and immediately the phone switched to CDMA mode, started displaying proper MEID (14 digit) instead of IMEI (15 digits), allowing to update profile and PRL. I called FreedomPop customer service and gave them the UUIC number, and after several minutes my phone started working on the FreedomPop network!
I have been battling with this no LTE case for this Galaxy S7, BYOD. This is the official US unlocked version, and works with Sprint (on their whitelist), furthermore, my wife has the same phone rocking LTE with FP right now (BYOD as well, so on sprint network), so it's compatible with FP's service.
My understanding for FP byod (based on previous exp) is that if the phone was activated on Sprint network before, the MEID and the ICCID info is stored together, so even if BYOD process only ask for MEID, as long as you have the previous activated SIM, the ICCID info get carried together, so you normally would have no problem getting LTE.
This Phone was never activated on Sprint before, so when I first activated it BYOD, so no previous SIM info, but I plugged in a compatible SIM that was activated on Sprint network before (with another MEID though). My initial activation had problem (red bar on my account summary), had to email customer service to add this ICCID. Phone passed the hands free activation and all. No problem using the fp apps, phone, sms, cellular network worked (only 3G).
I then started to do all kinds of reset trying to get LTE connection. I have done,
1.##72786# carrier reset
2. Restore APN setting to default, clear cache, reboot
3. Matching all the LTE related parameter with a known LTE connected phone (my wife's GS7)
4. factory reset
5.Deactivate and then reactivate the GS7 (by swapping devices between two fp accounts)
Now almost three months now, I'm still facing the same issue. FP customer service has been helpful doing the routine checks, but not beyond the suggestion of PRL update/reactivation. The final solution they offered was to deactivate the account and the activate the GS7 with another byod account. I did this just today, by swapping another device in this account, and then reactivate the GS7 to that account.
My very first concern is if the ICCID info has been accurate (not missing or mistaken a digit), but I asked them to verify this at least three times, nothing came back as error.
Compared to my wife's same GS7 with fp, my phone is rather slow to establish the 3G mobile data connection, for example, her phone would almost show LTE instaneously after a reboot, but my phone would be at least after a min to show the 3g icon.
Can someone share some insights on what else I could do? I just could not think of anything else from my phone side to do. A note worthy thing is, when I helped BYOD my wife's GS7, I was in the same boat of needing to add ICCID via customer service to pass HFA, and then all the reset to get the LTE. I actually wasn't able to get LTE connection by what I did, shut off the phone with 3G connection, but next morning I turned on the phone, LTE was there. Along with me, I saw multiple users who had similar no-LTE problem report they were getting LTE same day.

Hi mate

So, previously when I went into network operators, next to T-Mobile there would be a little sim card icon. This has not shown up, and it will not roam off T-Mobile. If I do manually select ATT when I have no Tmo service, it refuses to switch back without multiple restarts and sacrificing a goat.
I've noticed that this is also happening on two Nexus 6 phones I own. Same deal, no sim card icon. They will roam off Tmo, but often times get stuck on att if there's strong enough att signal. Interestingly, the one that is bone stock has even more trouble switching back than one on a custom rom.
Did Tmo change something, or is it something on my end? because I've not changed anything on my G5, it's rooted and running stock (M update right now) with TWRP recovery and it worked fine before. The two nexus phones haven't had issues like this in the past either.
