Did swapping my LTE sim card break something? 3G only? - Verizon Samsung Galaxy S III

I've been using the LTE sim card I received with my Galaxy S3 back in 2012 with a Moto G LTE I bought several months ago. I recently cobbled together a Galaxy Nexus from a couple of broken devices. I noticed that this phone would only connect to 3G (EHRPD), but when I tried to use the sim card with my S3, Moto E LTE, and S6, those devices will also only connect to 3G. I have tried both Global and LTE/CDMA on the devices that will let me, but the phones still do not connect at anything other than 3G and I did not dial *228 or *228nn from any of my phones.
Did I break something? Is there anything I can do to remedy this situation to let my phones connect to LTE again, or do I need to obtain a new sim card, and if this is the case, what's the best method to obtain a new one?
Thanks!

When I needed a new sim I just went to the store and explained it wasn't connecting to LTE and they went ahead and replaced it without any fuss.

[Q] Enable Verizon band 13 on the Nexus 5

We were able to get LTE working on the Nexus 4, abit crudely though, I read something about the Nexus 5 having an adjustable tuner, or something like that. Any chance somebody can "adjust" it to work on band 13 for Verizon?
I currently have a Galaxy Nexus, what would happen if I put my SIM card into the Nexus 5? Would it work with CDMA? It has the right CDMA bands and frequencies that Verizon uses. And if I was in an AWS band 4 area, I suppose LTE could work as well.
I know that I can pop my SIM card in any other Verizon phone, and it will work, CDMA and LTE. I don't need to go to Verizon to activate the CDMA part of the phone. So let's say I got a G2 and put my Galaxy Nexus SIM in it, it would work just like my Galaxy Nexus. So if I put my SIM card into a Nexus 5, wouldn't the CDMA just work because my SIM is there and it has the correct CDMA bands? If it does, I guess all we would have to do is get band 13 working so we can get full LTE support on Verizon.
I'm almost compelled to buy a Nexus 5 now and try this out, and hope somebody figures out how to get band 13 working.
Am I just dreaming or what?

I'd say it's easier to leave VZW.
Can you just do hacks and get the band to work?
And secondly it won't work. There have been countless posts about this. When you pop your Sim in it may take a while for service because Verizon is checking the imei on the phone to either grant it access or deny it access to the network.
I'm sure many people have ordered one and hope it will work (I have seen comments on dlife about them).
If the actual hardware components (Transceiver, Power Amplifier, Filters, Duplexers, etc..) on Nexus 5 support Band 13, maybe.
But you can't magically software enable something that doesn't physically exist.
How are you going to add the ESN to Verizons network???

Yes the actual hardware supports Band 13, this phone hardware wise is a G2 dressed in a different set of clothing and that's it. My Nexus 7 LTE works just fine on Verizon's Band 13 and my IMEI is not in Verizon's database. Now Verizon wont activate a sim in a device that isn't in their database and Verizon CDMA has always been unlocked. I am betting money if you take a sim out of an iPhone 5 and live/visit a market where Verizon is doing LTE on AWS and pop that nano into a Nexus 5 your gonna auth on the LTE network and your gonna be working 100%

I currently have the Galaxy Nexus and Nexus 7 LTE. The Nexus 7 LTE's IMEI is not in Verizon's database and it still works when I put my Verizon SIM into it, and it does not take it a while to get service.
I understand things are different with CDMA, but I still have a sliver of hope that somebody will get this working on Verizon.

Same sentiments except the Nexus is micro sim so you would need a converter. Band 13 is controversial because VZ has a consent decree to allow open device access but other bands are not covered. Since Band 13 is not enabled a hacked modem FW need to be installed to enable as such. The Nex 7 LTE does not support CDMA nor Voice so that is not exactly the same.
BTW my S4 now shows Band 17/20 support with the new MJ7 Modem update.

IMEI can be activated by Verizon

Okay so non-vzw device is actually a common issue. It is completely possible to activate a non Verizon device on the Verizon Wireless network, thought it's not something we advertise, and chances are you if you ask us if it's possible we will give you the blanket answer of no because many phones designed for other carriers are locked to that carrier, it is possible to unlock it for activation on another network (eg AT&T iPhone on Verizon network) but it's not something we do. When we receive something that the system does not recognize (it can only be done by placing an active sim into a new device) we have to fill out an e911 compliance form and manually add the MEID/IMEI to the system, tech support is capable of doing all of this upon request.

Please ignore
FYI: I have a Nexus 5 on latest Marshmallow update and it runs great on the Project Fi network after I activated the SIM in my Nexus 6.
Thought I would try this to answer your questions.
I have an activated VZW SIM which I swap out to many other devices, including the Project Fi version of the Nexus 6 (Non-VZW device), a Droid MAXX, GPE HTC One... and many unlocked tablets and MiFi hotspots without issues (so long as the bands are supported).
I popped the VZW SIM into the Nexus 5 and it recognized the SIM but showed no network service. I attempted the pre-configured VZW APN settings to no success. I then manually entered all APN settings from the Nexus 6 which works fine. Nothing... no service.
While you may be able to get VZW to manually add your IMEI to their E911 database, I doubt it's worth the effort.
In Short and to re-confirm all of the previous posts... NO, you cannot use a Nexus 5 on Verizon wireless.
I recommend you go pick up a 5X and it'll work straight up out of the box.... or sign up for Project Fi. I love Fi but keep my VZW for the unlimited data.

[Q] I lost LTE on AT&T

I was on a trip recently and I turned off LTE through quick tile because the place I was staying at did not have LTE. Now, I seem to be stuck on HSPA.
I reset network settings and even did a complete wipe of everything and I am still stuck on 3G. I have Preferred network type set to LTE (recommended). I am using the ATT LTE access point (screenshot attached).
Any ideas? Any way to check if it's hardware of software? I am running 44S.
I used to have LTE here and my gf's iPhone 6 has LTE in the same location.

I'd think the only reason it'd be hardware is if something went belly up. Seems doubtful to me as bard hardware is fairly rare. More likely software. A few times I've lost LTE after changing out my sim card, and only the phone company doing some type of reset has 'fixed' it. Not often, but enough to be a PITA.

Add "hipri" under APN Type, save, reboot & see if that helps. :fingers-crossed:
Put your sim in your gf iPhone and let it get an Att signal then put the sim back in the opo that's what I did with my phone and it worked

I tried that. I also put my sim in other OPO and it got LTE. I get LTE with my sim card on OPO thats usually on t-mobile (but his sim did not get LTE on my phone). I also tried my SIM in a nexus 5 and that got LTE as well.
Im fairly sure its hardware failure

if t mobile lte works on your opo and not at&t, im sure it's at&t issue.. Do you have a global/international opo unit?

I was not able to get LTE with the T-Mobile sim. However the other opo got LTE with my ATT sim.

Using cricket sim on device?

I have a straight talk S3 (Verizon based) and a cricket sim card. How do I make the cricket sim work in the phone?

You need a CDMA SIM from any CDMA carrier and it will work as soon as you put it in, then you set your APNs to Tracfone APNs.
If your Cricket SIM is a GSM SIM then it won't work, it MUST be a CDMA SIM.
Verizon CDMA LTE SIMs are only $3-5 on eBay. I'm sure you can afford the price and the wait while it is mailed to you.

I used a friend's Verizon Galaxy SIII at one point... kind of... it took a while to detect the network each time the phone started up and it was only EDGE/2G
So, it works for phone calls and very slow data... might be okay if you're usually on wifi, but it's really better to just have a phone that is compatible with Cricket's HSPA+ 3G and 4G LTE network(s).

They are asking about the SIM because they have a straight talk s3 and that device has to use Verizon S3 ROMs and that makes the Straight Talk S3 require a SIM to have working mobile data, it won't work without the SIM. They weren't asking if they can use a Straight Talk S3 on Cricket network.

T-Mobile Sim No Signal(Other sims work)

Recently revived my N5 that had been sitting around due to my N6P showing some water problems in case I needed to switch phones quickly.
Well, after resetting and installing AOSP Extended, I put my T-Mobile sim in, and gets no signal. It will recognize a sim is in, but I get no service at all. I figured something could be wrong with the simreader, so I tried some other sims. Sprint sim and a Freedompop(AT&T) sim both work. I know my T-Mobile sim works, as I'm currently using it in my 6p. Anyone have any solution?
freedompop uses at&t for GSM devices and sprint for CMDA devices. it sounds like your phone is the CMDA version, and your using the sprint network with freedompop. T-mobile is a GSM network and will not work with CMDA phones.

XZ Premium / LTE on AT&T? AT&T says I'm only using 3G

I'm being told that my device is going to be booted off AT&T because my XZP is only running at 3G (according to at&t support engineers). I find this hard to believe.
I had some initial issues with the sim because I used the sim from an older phone, which could only do 3G, so it wasn't registered on their network as capable of anything else. The jerks in the store were of no help, and even got attitude with me about dropping my sim into a new phone to see if it would register. Luckily, I had a bud who had a brand new LTE AT&T phone, so I popped my sim in there, let it register, get access to all their new/current bands, and then I put the sim back in my XZP... lo and behold, all the capabilities were unlocked.
I have been running the at&t apn for high speed, phone started using 4g+ when the LTE rollout finally got fully deployed.
In trying to run down if AT&T is full of crap or not about kicking my phone off the network that is "only using 3G"... I came across this https://apn.gishan.net/en/apn/att/sony-xperia-xz-premium
It shows I should have a bearer of LTE, and I do not. I have 4G and all of the older network types, but no LTE. Does anyone else have this? If so, what network are you on? My phone should be current on its updates, as old as they are...
Maybe I need to drop this sim into a current gen phone again and let it register on their network?
Any ideas/feedback is appreciated.
