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?

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?
Hi All,
I bought a Tmobile galaxy s blaze 4g (SGH-T769) from HSN last year, it was never activated or used on tmobile. I tried to put a old at&t sim I had in it and it said sim invalid. I get the same message when I put an active Verizon sim in as well.
I used a service online for an unlock code and after following the directions it prompted for pin and it seems to be unlock after entering pin
When I insert the Verizon sim it does not display invalid but it cycles between Verizon APN and Vodaphone NL .
When I try to make a call it said not registered on network
When I put the at&t sim back into the phone, I get the not registered network but am thinking because its an old inactive sim or not?
My issue is I want to use this phone in Brazil this summer so I need it unlocked and right now I am not sure if it really is unlocked?
any ideas?

Just so I get this correctly, Verizon, even though it has a sim, is CDMA network Only. So my my only option to test is a vlid AT&T sim?
Thanks for responding
update
I used a friends at&t working sim and it worked great so the phone is unlocked. I guess the Verizon 4g lte is different frequency anyway plus for some reason I thought it was some form of GSM. lol
ALL good to go here..
thanks
I just opened a brand new (not activated) Verizon SMG920V. I thought these phones were unlocked for international use.
When I put a Rogers Canada SIM I get the "Non Verizon SIM, Activation Required" message.
The only options given are to use WiFi and to Emergency Calls.
What should I do to use this phone with a foreign carrier?
It unlocked for GSM. If your frequency's are supported put it in Roaming mode and the right APN in, it should work.

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 .
Hello,
I have called Sprint many times, after they keep telling me it is unlocked domestically and internationally, I finally gave up. The phone simply says to contact sprint to unlock. I have no idea what to do. When I press UCCI Unlock it gives me an internal error(407). I tried flashing unlocked firmware (U1) But it does not work on that either. Tried booting up with T-Mobile sim inside, still same result. What to do?
Please help!
Is Sprint GSM? I thought it was CDMA.
T-Mobile is GSM.
What is the message your phone displays when inserting the T-Mobile SIM card?
As you know, Sprint is a CDMA network and T-Mobile is a GSM network, but the S8 supports both types. but you need to make sure the SIMs are both activated and the phone doesn't asking for an unlocking code.
Also, check if your phone's IMEI is clean in sprint database http://imeipro.info/sprint_imei_check.html
