How to unlock samsung verizon i920 Omnia II 2?

hi How to unlock verizon i920 Omnia II 2?
I've connected the phone to another network operator but 3G did not work. They said they didn't know how make 3G (ev-do) to work for this phone.
Do you know what is the problem and how to solve it?

I use this phone in CDMA operator not with GSM. It works fine but only voice ((( and there is no internet connection (CDMA2000 1x. EV-DO - usually it's called '3G')
My opertor told me that it was because of verizon firmware. the phone is locked or something like that.

[Q] SIM Not Detected - Google nexus S I9020A

I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked
Sent from my ice cream powered Nexus S

Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)

I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.

Tried a new sim?

im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.

did you try to reset the phone?

[Q] no network on verizon xt912, using in india

hi all,
i have a xt912 - original carrier - Verizon USA. I am trying to use it in India. I have tried both CDMA as well as GSM sims in it. When CDMA inserted, it shows no sim(sim is shown as crossed in network notification area). When i insert GSM it tries to search network and restarts repeatedly until it shows No Sim. Please confirm if this error is due to subsidy lock on this phone. Should i buy an unlock code?

Thought VZW and SPR are giving SIM unlock service under the certain condition.
http://www.verizon.com/about/consumer-safety/device-unlocking-policy
Like VZW clearly states on their website, that they don't usually lock their 4G devices, so I guess S7 is included?
So as SPR
https://www.sprint.com/legal/unlocking_policy.html
you just have to use your device in certain amount of time on their network and they can unlock it for you.
Unless you can't connect to their network, I really don't see the need of any "programming" or "unlock SIM" that you do refer to.(though unlock SIM doesn't exist for Galaxy S7)
And lets talk about using your device on CDMA network. You have to be aware that which CDMA is used by your career and on which band, as CDMA is mainly ONLY used by USA,JAPAN,KOREA,China(sorry if I missed any) I think very few device supports CDMA, so it might be quite DIFFICULT(or even impossible) to use GSM device on the CDMA network.
Maybe you need to clarify a bit what information you need exactly?

In yemen we use cdma on cdma2000 ev-do band and gsm so My phone is compatible with this two network(s7/sm-g930p).why i need to use programming sim becuse to use both network cdma for internet connection and gsm for calls but not in the same time.i have to swith network band to use one of them .in phone store they have a method to unlock sim and progamming sim to work on cdma.i don't now the method but maybe by dfs .
