Hi, im from Ecuador, my mom buy a Core Primer in Verizon in New York, but she is going to stay here in Ecuador like 6 months, we want to put she another sim from Ecuador carriers, i tried one, and went to a service reapir store and they said that we can unlock sim lock becuase verizon phone is in cdma, and doesnt have option to change band, but im wondering if i can flash a firmware from another carrier to unlock the bands so we can use another sim chip. an somebody guide if this i possible or not, thanks

what do i have to do? can i use two service providers at the same time? can i use tmobile for voice and sprint for data? can i use tmobiles aws 3g band? has anybody done this? do i need to use my turbo sim?
I have heard reports that the GSM in the US doesn't work. Also, the FCC filings state there is a lock to prevent this from happening. I really hope someone can find a crack soon so I can use the Sprint TP2 on ATT.
However, I have heard some people getting the Telus version unlocked to work on GSM.
i'm interested in this as well - i've got a work cell that's got a tmo sim and would love to be able to pop the tmo sim in my tp2 and be able to select somehow which phone #/network the phone call comes from

Well, you can already select GSM, CDMA, or Auto on the phone. The only problem is to unlock the firmware so US GSM sim cards will work. Hoping Olipro or cmonex have something up their sleeves.
I just bought Verizon Samsung SCH-I705. I just wonder that can it could be unlocked to use Tmobile SIM. I know that this one has LTE SIM but just wonder?
I'd like to know the same
ill like to know that too

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???
This is really wierd. Hope someone can help.
I bought an unlocked LG Optimus G E971 phone in Toronto, Canada this May. Inserting a Rogers and Fido SIM card was perfectly fine and working while I was in Toronto Canada. No SIM network unlock PIN required.
In October, I travelled on vacation to Hong Kong with the same phone that I thought was unlocked. As always, I would buy a local SIM for my unlocked phone. To my surprised, it prompted for a SIM network unlock PIN. I went to a total of 3 carriers, including 3 Telecom, China Mobile and one other (cannot remember the name). All asked for a SIM unlock PIN.
Not believing what had happened, I went back to the shop in Toronto, Canada after returning home. Tried inserting Rogers, Fido, Bell and AT & T SIM card, all worked perfectly.
My question is, could this be a region lock? Like the Samsung Galaxy Note 3?
Anyone has similar experience to share?

Probably.
Region locking or maybe that your phone did not have the right baseband? I dont know. My phone had a similar problem, it displayed roaming in the native country I was.
If you find something about it, please do post back, ok. I am very curious to this issue.
You need to unlock the phone from your carrier in order to user unlocked sim on your mobile

I can use both Fido/Rogers and Bell. They are different carriers and Fido and Bell are competitors in Canada. My LG Optimus G E971 is manufacture unlocked meaning its brand new and unlocked when I bought it from the shop. I don't buy locked phones from carriers and I don't need an unlock code. Been buying and using manufacture unlocked GSM phones in the past 10 years, never had an issue. Not a believer of locked phones and it's ripped off plans in North America.

The LG Optimus G E971 is quad band and it has HSDPA 850/1900/2100. I matched this to my Samsung Omnia II (I8000) which has HSDPA 900/1900/2100. My Omnia II is manufacture unlocked and is usable in Hong Kong (Asia) without an issue. Not a phone tech person but I would assume my LG Otpimus G E971 is quad band and is useable in Hong Kong.
I didn't know there was a section for LG Otpimus G, I have also posted my replies here:

I switched to sprint about 5 months ago and I got my s5 with a 2 year contract. We also got another line with another phone. The account is in good standing with payments on time always. Will Sprint unlock it for me so I can use it on a trip im taking overseas? I'm not sure what their policy is..and I know they do it OTA, so that means I have to be on stock rom right?
Yes stock rom. Sprint more than likely unlick. Of course you will have to mnew monthly charges. But depend sd wherr your going. If going to us territories sprint will work. Just call sptint anf see
They will usually unlock it for international roaming after having the phone on your account for 90 days.

please note that most of the world is now based on GSM and Sprint is a CDMA based service. Once unlocked you would probably need a GSM sim card installed in order to use the S5 (this sim card can either be one from the US, a more expensive option, or a local sim wherever you are traveling to).
In Europe, especially UK, there are many cheap GSM sim operators.

Yeah that's the plan for me to buy a local sim in that country so I can use the phone with a local number there. Do you know what bands the gsm works on?

Depending on the country involved they use 900 and 1800 mainly but the s5 has all the bands used in Europe. Note that T Mobile is a major carrier so you should be ok with this phone if it is truly unlocked
ok so i have this new s22 ultra SM-S908U and it was connected with Verizon wireless originally. cricket when doing an IMEI check said it was not compatible, I called and Customer service confirmed it was not compatible due to network band differences. i decided to try using the cricket sim anyways and it worked for about a hour then cricket locked the sim and i had to get another sim,
Does anyone know if and how to get this to work on cricket if possible? I did try this band unlock
( https://forum.xda-developers.com/t/...ies-including-sub-6-and-mmwave.4488435/page-5 )
also but not sure if i did it right it locked the new sim and again i had to get another one.,
Also I did check with verizon and the phone is sim unlocked
