Possibly simlocked?

Is it possible I bought a simlocked I9020A? Works fine on at&t but my tmo simcard wont work at all (no edge). I got it off craigslist but did a factory reset, so figured anythng the previously owner did should be undone.

Aren't all GSM Nexus devices unlocked by default, only difference being GSM/3G frequencies?

So why did you buy an att nexus s when you have T-Mobile?

If you're able to make calls with the tmo sim then it is already sim unlocked. Though I am not sure why you're not getting edge.
Btw, is it rooted?

Wrong apn settings?

yeat I thought I'd at least get edge with a Tmo sim in. I use ATT in the US, the Tmo sim is my womans and was just to test it since since we are traveling to Europe in two weeks.

It won't hurt to check your IMEI and /efs
Sorry, didn't see that it works on AT&T :/

You should get Edge at least. Guess there's something wrong somewhere else. Talk to your carrier. If you can use some features it's not simlocked at least.

I would try adding a tmo apn. Not sure if it'll work but worth a shot.

I have the same problem, but the other way around. I have an I9020T which does not seem to work at all with AT&T. I've made many phone calls to Tmobile, to AT&T, and to Samsung's tech support. I haven't found a resolution, yet. The last thing that was told to me by the AT&T tech support person this evening, was that perhaps I need a newer simcard - one that is fully compatible with this newer model of phone.
I'm also prepared for the possibility that the phone has a hardware defect, however I don't want to send it in for an RMA until I'm absolutely certain.
Samsung (after checking my IMEI) has told me that the phone is definitely sim-unlocked and usable on any carrier.
A couple helpful hints when talking to any tech support person:
Make sure that they cross check your IMEI number. They have a database, and if they can establish some facts about your phone that way, it can really expedite the process.
Also, be aware that tech support people step through flow charts with you, and they usually aren't actually very technically savvy. If you can get them started on a constructive tack - they'll find the right flow chart, and you might get a lot more help than if you simply call up and say "it doesn't work."

no I cant be done point blank..are can I root then switch it? if so do you have a link so I can learn to root it..

The short answer is no it can not be done Verizon is a cdma phone the other is a GSM phone.
Have a great day!

Post #48. If you do not have data, you need to root and edit your APNs using the steps on the first page. Highest speeds you'll get for T-Mobile/AT&T are Edge (2G).

Actually, there is a GSM setting on the phone, and from my understanding, the GS3 is a world phone, and I think the I535 has the proper antennas to work on AT&T's 4G network, but I may have to look into that. It was something me and one of my coworkers were gonna try, but never got around to and he is now in the military, he had a AT&T GS3, me a Verizon, and we were gonna SIM swap and see if it worked. Hardware seems to support it would, but the big question is why?

Unless there's a breakthrough in this bounty thread, highest speeds you'll see on AT&T or T-Mobile are Edge. Hardware supports "up to" HSPA in other countries given differences in frequencies. Not sure I get your question of "why?" though. Samsung made this phone to support virtually every carrier in the US and it makes more sense to hardware lock (or carrier lock or whatever the technical term is) phones to only have access to most common frequencies in that region.

My question as to why is to the whole carrier swap. When you sign a new contract, you get a new phone, adding a customer owned device doesn't change plan price, but does maintain the upgrade eligibility. As far as I know, the major players haven't started releasing specs on next years devices. So, why the want to take a Verizon GS3 to AT&T is what i'm wondering.

Agreed, although I could understand if he said T-Mobile it makes good sense on their new plans. This just isn't a good idea trying to bring it to AT&T

Yea, I always thought AT&T had similar pricing as Verizon (expensive) but I'm not one to inquire into folks personal decisions on switching carriers with this phone. I'm only interested in doing so when I travel overseas. Everyone has different needs, you know?

Yup, same process for AT&T and T-Mobile so long as you have the respective sim. I'm unsure if you can edit and save APNs on stock which is why I say if you have no data then you need to root for the method I linked to. You can get calls easily on stock, just have to adjust Network Mode accordingly.

Rooted phone, trying to unlock 4g/LTE

Hey guys. This should be a relatively easy one for some of the people here I think.
I recently bought a Verizon GS3, the i535. I'm in Canada, and was unaware this phone did not access the 3g/4g/lte bands here.
Quick question: I have my phone rooted and I'm looking at installing custom roms. I've been lead to believe some roms can unlock the bands that I need on this phone. Is this true?
I have obviously tried searching but the results always come up with EVERYTHING lol. I would just like a clear decisive answer, from someone who has possibly done it?

Ok so maybe it's not an easy one? ...
btw there are way too many image verifications on this forum, holy moly lol

A rom will not change any of those settings, the best you're going to get is probably edge data, but 3g is possible under some circumstances.
Are you on Verizon's network? If not you're going to have to change the apn to get it to work on your carrier.
Sent from my SCH-I535 using Tapatalk 2

No I'm not with Verizon. I'm not even in the US lol.
I bought a phone stupidly and believe I am now paying for it. The phone technically has all the bands and settings. You can do the #*2263# thing and get into options to select / "force" them...but they just dont take or something?
I only have edge connectivity right now, you are correct.
This whole APN thing is very confusing or I'm very stupid. I"ve entered my carrier, Fido's APN settings and it does nothing because the phone isnt using the correct bands.

The Verizon phone is technically an international, or global phone whatever you wanna call it. in the hidden menus of the phone there is a place where you can manually select the CMDA, GSM and LTE frequencies.
Does this not mean that the phone -has- these frequencies and that its just something Verizon has done to keep the phone on THEIR network?

Theoretically it should be able to work, but the development for that feature never took off and all the bands weren't unlocked for all carriers. But changing your apn might enable a band you need for your specific carrier to give you 3g data.
http://forum.xda-developers.com/showthread.php?t=1809314
This might work, and the simplified method might open a band that you need.
Edit: and yes, locking down other bands is Verizon's way of keeping it on their carrier. You can pay them a hefty fee to unlock the band you need if you're traveling, but this isn't really an option for you. There's a bounty thread trying to unlock these bands in the general section, but it's pretty much dead nowadays because most of the devs capable of figuring it out are on newer phones.

Haha, yes basically that's what that entire thread says, but the basis of it is converting an apn manager to a system app. That will allow you to make an apn stick, which should force enable the bands you weren't able to get working in the first place.
Selling the phone isn't a bad idea either, then you can do a little more research and find something that might give you 4G signal. There's no way you're getting anything that good with this phone.

Well when you say that you make it seem so easy LOL. I've had the same blackberry for four years and just 3 days ago bought this S3. I had no idea companies would still be doing this locking bands nonsense. If I do sell the phone, anyone I sell it to will just be in the same boat I am right now... and theres no way I can sell this things to an American for what I paid for it.
Sigh

Another thing that is very confusing to me is a lot of people are posting that they need APN manager to be able to edit APN settings. My phone allowed me to do that out of the box, and like I mentioned, I was able to add my carriers APN stuff, but only get 2G speed.

Somebody will take it, if it's brand new then $400 isn't unreasonable. You'd do better with the i9300 model.
Any phone tied into a carrier is going to have issues like that, but I'd look into either getting the international versions of phones, or possibly a nexus 5 if it works on your carrier. That phone looks pretty amazing.
Again, trying those settings wouldn't hurt anything and might give you what you're looking for, post 108 has the simplified procedure in only like 5 steps.

I found that post, and read a few following pages and there didnt seem to be any input. Its almost like no one saw his post. I did go into my phone, and all of those settings are there. The GS3 they dole out up here is the i747.
This things could go for upwards of $400 in the states? I only paid 315 up here, and it had all the protective stickers and nothings been opened lol.

Well I bricked the phone playing around with it...
Installed CWM for some reason, cant remember why. First thing I click was backup current rom, phone rebooted and now says software not authorized by verizon. I hope some of you more mentally capable folk out there find some comedy in my errors, because I have no clue what im doing

[Q] [K2_PLC, Cricket]Cricket 4.2 MSL thingy is weird?

So I was messing around in the ##3282# settings, and I clicked "Edit Mode". I thought, "Well, let's guess." I inputted six zero's, and to my surprise, it was the correct MSL code. I don't know how this is but now I can edit the stuffs. Also, this phone has Band 25 LTE 0_0 I didn't know that. Can any of you Cricket users verify that this is only me?

MSL Reader (see the play store) gives it to you if you are properly rooted. Its how I retrieved mine. But I know six zeros won't work on K2_CL lol.

I dont know all the specs behind it cause there was tons and tons of info and I kinda spiderwebbed out of control reading it. But the jist I got is this PRL's APN's and all that get more credit then what they are deserved. Yes to have a proper one is beneficial but its more about the codec's the radio signal of the phone and towers your connecting to and the system files in your phone itself that will allow you to do what you need to. I am still piecing things together but I am working on a finalized cricket fix to allow the use of LTE, the use of gsm or cdma and the use of European roms. It has become quit the undertaking but before you jump in and start changing files that were initially fine I would properly educate your self on the pros and cons changing the prl.
As of yet I am pretty sure Tmobile wont flash the phone nor will our phone work on the Tmobile network

Lol I was just going through threads and it's also helpful info for others as well

I have an HTC one SV from Cricket, I like the phone but am not "In love" with it. My problem is this- I just bought the phone then changed providers due to poor service at my address. Since my phone has a SIM card I thought I could switch to AT&T but the phone never accepted the new SIM. AT&T couldn't find out why, Cricket told me their was no unlock code, HTC said it wouldn't work until they ran the date of manufacture and MEID# then all changed.HTC told me to get the msl and I can change the network settings so I I can use GSM instead of CDMA. Any warnings, advice or instructions?? Out of severe stubborn motives, if at all possible I want this HTC on GSM just to prove that I can lol.

[Q] How to get Nexus 5 to work on Sprint

I recently bought the nexus off someone and found out it was the one that came from tmobile but was factory sealed. I put in my sprint sim from my htc one but it wouldnt activate to the network. after the setup process it shows that its on sprint but cant make or receive calls or texts( no data). I know the nexus can work for all sprint its just getting them to enter in the IMEI manually which they say they cant do. Id rather not go through the process of reselling and finding on that someone got from sprint so has anyone gone through this issue that got it working?

you have to call them to add your imei into their system. nexus 5 that sprint sells already is in their system, but yours came from tmo. so it manually has to be put into their system. problem is many sprint reps dont know that and will tell you its not sprint compatible. but it is, they just dont know.

you usually have to get a tier 2 tech support person to get the IMEI added into their system.

While there technically is no such thing as a sprint specific Nexus 5, from a practical standpoint there is in that Sprint did not load any of the IMEI numbers into their system from the devices that were sold directly from TMobile. Without the IMEI number in Sprint's system, their frontline agents have no way to activate the phone. As was mentioned in a previous message you have to get elevated high enough within Sprint to get the IMEI number added to the system. I have not personally tried that but have heard that the results are hit and miss.
