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

This has been asked before and the answer is still the same
Verizon - CDMA Carrier
TMO - GSM carrier
Two different radio's. You can use an unlocked TMO tab and use it on AT&T (Another GSM carrier).. The Verizon tab shouldn't have a SIM card in it. Unless it is a World tab or LTE. In the LTE case, only the 4G is sim controlled, the 3G is controlled by the CDMA radio.
Verizon:
Frequencies and Data Type Digital: (CDMA/PCS)/1x, EVDO Rev A, LTE (Band 13 only)
Tmobile
Frequencies and Data Type GSM: 850/900/1800/1900
So your answer is no.....

I believe you answer is just partially correct. My Verizon Tab has a SIM slot. I currently own a Verizon Iphone 4S, Iphone 5 and Samsung S3. Used to own BB Tour, Storm, Bold, HTC Incredible 2, HTC rezound. After unlock, all of them (they have both CDMA and GSM) can be used with any SIM card. That why Verizon called them Global Phones. I also believe that the Samsung S3 is LTE phone with SIM card slot and I have no problem to use it with my TMO SIM card

My US Cellular S3 had a SIM card too, but USCC is a CDMA phone. The SIM card was for 4G LTE only as USCC is a CDMA carrier. Some of the BB was "World Phones" meaning that they had 2 radio's in them, 1 CDMA when you was in the USA, the other was GSM when you traveled outside the USA but could not be used inside the US unless it was (the GSM part) unlocked. I know there are some other Android "World Phones" I had the Motorola Electrify, I think it's counter part on Sprint had a different name. There was a few more on USCC that was World Phones, They had dual radio's. But the S3 and Note 2 didn't. But I would guess that it could be possible that Verizon's variation could be different. I never looked that close. But if there is a way to unlock it and use it on a GSM network, then do a search, the phone is old enough to have already been unlocked, and a search would turn it up if it was. If your search comes up negative, then you will have your answer.

Thx for your reply. My Verizon Samsung S3 was unlocked by Verizon (by agreement from verizon with FCC) as they did with Iphone 5 (can be considered as factory unlock). Both of them can be used with GSM carrier here but not the Iphone 4S (for abroad use only even it is unlocked by Verizon).
I searched and have not seen any solution for unlock the Samsung Tab I705 in US but there are unlock code for sale for I705 in Europe and in Asia. I checked the I705 specifications but only see LTE 700Mhz, Class 13 (as you stated) in your previous post. Same thing with Verizon Samsung S3 I535 but I can use S3 with TMO sim. That is the reason I want to find out anyway we can unlock I705 (Tab 2) to use with SIM card for GSM carrier. Anybody can help?
DAMN!
I was looking for the same thing!
>.>
yes it can be done
I know that the verizon galaxy tab 2 can be unlocked. A friend of mine had verizon do it by claiming they where traveling outside the country, and it works on T-Mobile just fine. because it does have both radios. PLUS i want it for the LTE anyways and it does work for the t-mobile LTE. problem for me is that i no longer have an account with verizon so they will not give me the unlock code for the tablet so i need another way to unlock it.... can i do this by rooting it and putting a customer ROM or does that no effect that portion of the tablet.

I have Samsung Tab E Verizon SM-T567V it's Global and 4G supported with a dedicated sim slot. How to sim unlock it???
I am having trouble searching for this because it always shows forums on how to configure apn if you are planning on using AT&T sim card.
I just want to know if I can gain AT&T service on a tmobile phone with a tmobile sim by configuring the apn settings.

This is not an option. So no

you can unlock it and use a at&t sim card on the t-mobile phone.
Hello, It is my understanding that Verizon phones are unlocked. have an HTC One phone that I would like to switch from Verizon to ATT. When I put a new sim card in the phone, it seems the ATT network is being blocked. Any thoughts?

Vezion is a CDMA provider which does not use sim cards (only mini sims i think for specific devices) while att is GSM which uses both mini sims and regular sims.

Thank you for your response. The HTC One has a mini sim card. I have an AT&T mini sim card to put in the phone, but when I do so it doesn't recognize the AT&T network and the CDMA/GSM setting is blocked. There is a way to switch networks. Could someone please help me out in identifying how? Thank you for your help in advance!

Verizon LTE phones are all sold unlocked and use sims. Also every model that I can think of sold in the last couple of years has GSM bands to be sold as "world phones". I appreciate the attempt to be helpful, but spreading misinformation is the opposite of that. After some more trial and error, it was an ATT provisioning issue
Can anyone tell me if the phones is region locked? Thanks
i am not sure what you are looking for but i do know that there is a thread on here where someone tried a Verizon SIM in a Tmob and ATT S6 and neither one worked on Verizon.
Generally Verizon phones are SIM unlocked so u can use them on Tom or att but don't expect to get lte coverage since the phones have different bands enabled.

That's because those don't have CDMA radios, and at least the AT&T one is locked. Verizon phones come SIM-unlocked and work with other carriers. If you use a T-Mobile SIM you'll see an "unknown SIM" message, but it will work assuming the bands match. You should be able to get LTE with T-Mobile as most of their network uses band 4.
He means region locked, like usa

Anyway to get rid of this message? My g2 I had to root it to get rid of it. I hope I don't have to root the s6 just for that because it gets really anoying just having the icon showing unknown sim the whole time.

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.
