Confused about SIM unlocking on a HTC Ozone (Verizon)

Hi all,
I got a HTC Ozone from Verizon. I know this phone supports CDMA/GSM networks. My phone is working on a CDMA network but it also comes a SIM card.
I have the following 2 questions:
If I remove that SIM card the phone still works on the CDMA network.
1. Does anybody know what is that SIM card for?
I have also tried to remove that SIM card and insert a SIM card that I have from AT&T. The phone just says that the card is invalid but it doesn't ask me for any unlocking code.
2. How do I enter the unlocking code on this phone?
Thanks a lot and sorry if this has already been asked but I haven't been able to find anything.

To answer your questions -
(1) The Pre-installed sim card is a VZW sim that allows you to use the phone internationally on GSM networks. You would pay international rates to VZW for that.

I did this and am able to use a t-mobile sim and At&t sim in the phone. You just have to make sure to have the phone in GSM network mode.

Thanks a lot! Everything is clear now.

hey guys,
I got the unlock code from Verizon (actually my company got it for me because I'm not the owner of the account) However, I don't know how to enter it.
If I insert a different SIM card (e.g. AT&T) it just says that the SIM card is invalid, and it doesn't give me the option to enter the unlock code like with other phones. I also tried to change the network to GSM.
Any ideas how I can do that?
Thanks

ok, I think I found it. Unfortunately they got an invalid code so they have to go through the whole process again

One slight problem for some of us, like me:
I'm about to purchase Ozone off-contract from VZ. VZ rep told me I'd have to put it on an account for 6 months in good standing to even get a consideration to be unlocked.
$350 for this? This is frickin' anti-competitive bull****, I'd be paying full price un-subsidized for the phone, I deserve an unlock.

I found mine already unlocked off eBay for about $290. It was an auction so obviously I can't claim you would pay the same, but it is an option if you don't want to submit to their rules.

as far as how long u have to be under contract... i was told by global support you have to have been a customer to 90 days prior to the unlocking and in good standing.
I upgraded a different line to get the ozone... put it on my primary account that same day and had it unlocked five minutes later. I think u talked to the wrong rep.

Wrong rep? I was at a corporate Verizon store where their Small Business Specialist told me that.

Yep... wrong rep... Global support is different then Small Business Reps.
How many times has one rep told you something that was contradicted by another rep?
I was simply telling you what I was told right before they unlocked my sim.
As a matter of fact, I just bought a BB Tour off eBay that i put on my account and had it unlocked through global support within 5 minutes. Only requirement was I have been a VZW Customer for more than 90 days and I am in good standing.
Shoot, if you want maybe I'll activate your phone for you on my account and unlock it...

unlock my HTC OZONE
hey man i just got a verizone wireless HTC OZONE....Pls could u help me unlock it?

Hi all, how to enter code in that phone?

My unlocked Tilt broke, and all I can find on Craigslist is an HTC Ozone. My unlocked Tilt is on T-mobile, so I can't call Verizon to get an unlock code
Is there another way to do this?

Go to http://www.unlock-now.com/. Enter your IMEI and pay for an unlock code. Go to Settings, SIM Settings??, select Enter SIM Unlock code.

Same here,
where I work we do not get VZW anywhere in the building. AT&T actually came in and installed repeaters so I plan on getting an AT&T prepaid and put the sim in my phone then I can just switch networks. Is that possible?

I unlocked 2 phones with www.unlock-now.com they work great and fast. I unlocked an HTC Imagio and an HTC Ozone.

go the unlock code from htcunlockcode.info and following instructions came along the code.
1. Switch to GSM mode
2. Go to Personal
3. Go to Security
4. It will says "Please enter the sim unlock code to disable the SIM lock"
5. Enter unlock code.
6. Reboot.
Worked fo me! hope the instructions will be helpful, as I see lot of people asking this in different forums.
xoxoxo
Jane.

thanks very much！
find the option to enter unlock code finally！

I got a code here http://unlockcellphonecode.com/code-for-unlocking-htc-mobile-cell-phone and they sent me the code and instructions ..

hi all. Ok I have a Mytouch that i got from google, didnt buy it at the store.
I want to unlock and have received a code for that. I have tried putting in an active ATT sim and I am not prompted for the unlock?..what gives..just says no service. Is there somewhere I am suppose to enter that information?
thankyou

so...i have to have the sim card in the phone of the service i plan to use?..So if i am going to europe i have to wait to get there to put the sim in and then it will ask me for unlock code?

if your referring to Carrier locked, is it locked to what carrier then?
if you put a SIM of the same carrier the phone is locked to, it obviously wont ask you to unlock it!
put in anoter carrier's sim and it will. then enter the code.

No its on tmobile now..if i put the att sim card in it just says no service.

Im not sure at all here but is ATT not on CDMA??
If thats the case then you need to put in a sim of a European carrier (GSM).

yeah sounds right thanks

ATT is GSM
did you test your ATT sim in another phone?

yes its from a working Iphone

Factory reset / data wipe.
This can occasionally assist folks with internal issues with the hardware. It's a common way to approach solving a problem with your device. Consider it, try it, and then go from there before continuing to further with the unlocking process.
Best of luck.

No sim card

I brought S4 just another day and when I insert sim card the phone says "No sim Card" but I inserted it already!
Its micro sim i'm buying another sim card today and see if it works,
Will customer service fix this if the problem is in the phone ? If yes then is it covered by warranty ?
Any help? maybe its software problem

And how exactly he should or anyone should know what's exactly your problem? Can be hardware or the simcard. This is up to you to find out.
First try a new simcard , and try to get one micro sim factory cut if you can, if still nothing means is hardware.

Did you put it in wrong?

You have the answer on this topic, if doesn't work with any simcard, bring it back.

GT I9505 doesn't detect LTE sim, works fine with 3g Sim
Hello all !
I own a 2.5 year old GT i9505 (LTE variant) which works completely fine with a 3g Sim but the "Sim Card not inserted" error appears as soon as a 4g Compatible Sim is inserted. Could this be a modem issue ?
I live in India (got the phone from Europe) and have been using 3g services without any hitch for the past 2 years. Vodafone recently launched 4G services here and my phone doesn't detect the new 4G Sim card .
My phone shows the LTE/WCDMA/GSM modes but doesn't detect the Sim card.
Tried with another Sim from the store that doesnt work either.
Details :
AP: I9505XXUHOJ2
CP: I9505XXUHOJ2
CSC: I9505EURHOJ1
All ideas and solutions are appreciated.

It's possible that there is something wrong with the phone's sim card reader. You could replace the reader for not a lot of money and it's easy to do yourself.

Maybe your phone is unable to detect LTE Networks from Vodafone India because from what I research, India uses TDD-LTE. You could Google-d LTE bands that used in India and compare it with your phone's supported LTE bands.

Thanks for your reply.
I considered that option but a 3g sim works perfectly. Do you still think it would help ?

I guess I am just lucky my phone supports both.

Still no luck !

I don't know that much about sim card technology. Have you tried the LTE sim card in a very old phone to see if the old phone detects the sim?

I did infact it works with every phone except this one.

Leads me to conclude it is the sim reader or motherboard if no LTE SIM cards work. Doesn't seem like software.

[Q] Sprint unlocked my SGSS

Hi I had my phone unlocked by sprint and got a confirmation email saying my device is unlocked for international use. I was told by the sprint representative that there is no way in testing if the phone is unlock when I'm in the US. Is this true? or is there a way I can test the phone if it's unlocked, I do have an international sim card from Jamaica but I want to test if the phone is unlock before I leave the states.

borrow a friends SIM?

this belongs in the Q&A section not general.
this has been answered already. you can test if its unlocked by putting an att or tmo sim card in. if there is no sim card error when you boot up.. then its unlocked.
the sim error would be in the status bar. "invalid sim". if you see invalid sim.. it's not unlocked, despite what sprint says.
if it IS unlocked properly.. that still doesnt mean that you can use tmo/att... itll only pic up a gsm signal when using an international sim.

I have a sim card from Jamaica, I am going to try it when I get home but I think I forgot to change the mobile network to GSM when I inserted the the international sim card.

Just got back from my trip to Jamaica and my phone worked great with the international sim card. I had the sim card with me in the US and it didn't work when I was here but as a landed in Jamaica I put the bad boy in and I had service only down fall was I couldn't get data. So the unlock from sprint do work internationally.

AT&T SM-T337A SIM unlock?

Got SM-T337A from BestBuy, paid full price and plan to use with T-Mobile.
Apparently need SIM unlock, however I read about "Region Lock" so it has to be "activated on AT&T first prior to SIM unlocking".
It has AT&T SIM card so when turning on it finds network even though I have no service.
Does it have to stay on AT&T network for a certain period of time with valid SIM card prior to SIM unlocking?

I guess there is no life on this planet

Anybody?
