[Q] Verizon model - Sim Unlock Possible - Xperia Play Q&A, Help & Troubleshooting

I am interested in getting the Verizon model for how cheap it is. Is it possible to sim unlock the Verizon model to use on T-mobile?
I know someone is offering a boot unlocks and regular sim unlocks with GSM models. Not sure if it will work with the CDMA model.
Insights?

He said he can unlock Verizon locked Plays as well.

He just said on the 12th page post of his unlocking forum that the GSM baseband isnt supported.

Hello,
I am still wondering if the root process allows the XPERIA PLAY from Verizon (cdma version) to be used as a World phone (by putting a sim card in the slot). I'd appreciate if you guys can tell me if this is possible.
Thank you
I think @netorino is right, baseband doesnt allow gsm networks."
I am just asking and double making sure cause I kept seeing people using the word "unlocked". And I know unlocked has multiple meanings. (boot, sim,ect)
I come from HD2 XDA.

Don't quote me...but I think you would be better off getting the AT&T play as its gsm as is T-mob, while Verizon is cdma.

Quick answer? NO, absolutely not.
Longer answer?
Basically the SIM Slot seems to be physically uncoupled from the chassis. Further, the chipset that would be running the GSM is replaced with one for the CDMA. Whether it can function as both is a question, but the chip is actually different (from my teardown to look, the chip numbering is different from the tech/repair manuals).
I would, in general, assume that no phone that is on Verizon (unless it specifically says "World phone" or "World Edition") can be used on T-Mobile. CDMA vs GSM silliness. Different frequencies, different methods, different technologies.
So while the bootloader unlcok could work for the CDMA model, the SIM-unlock wouldn't.
Interestingly enough, there are still traces of the GSM code in the phone's diagnostic menus though.

i have a friend that has a phone repair shop in my hometown. i called him when i found a play that is cdma thru verizon. it is a world phone and has a sim card slot. he said that as long as its a world phone version it can be unlocked for gsm use in the united states. idk im getting one tonight and im gonna tinker with it and once i get it all going i will let everyone know on here if it can in fact be unlocked for gsm use in the US.

Well???

well turns out that the phone ended up not having a sim card slot and the person that i was supposed to purchase it from had no clue about anything. i did not end up buying this device. sorry!!!!

This was stated years ago, the R800x has a sim card slot but it is turned off on a hardware level. It is a non-functioning sim slot.

Unlock Verizon Nexus for T-Mobile?

So I'm thinking of buying a Verizon Galaxy Nexus.
I know it has a sim tray so i'm wondering if it can be unlocked for T-Mobile.
Any help would be appreciated.

Sim tray maybe but the vzw one is cdma and the GSM one is...well..GSM.
Different technologies! Not compatible.
I have the Verizon phone and yes it does have a SIM card but it uses different radios. Verizon uses CDMA/LTE and T-Mobile uses GSM so you can put whatever SIM card you want in there but since it uses different radios it won't physically be able to talk to T-Mobile (or any GSM carrier's towers)
btw, what happen if you travel away USA in a country without CDMA?.
At least, the CDMA iPhone have a simcard tray but it's locked until your operator wants.

Starting with Verizon's 4G LTE phones they all require SIM cards. They were also used in 3G global phones (my old blackberry and droid pro had them) but the CDMA Galaxy Nexus isn't global so you'd just SOL.
well.
nope. it won't work cause it's not CDMA...

@[email protected] can't believe people are asking this question. The phone has been out for over 3 months now.
Besides, the SIM card slot is specifically for LTE... as in, the SIM card is an LTE SIM card. LTE, not HSPA+.
I can only think, because the AT&T (HSPA+) model would be more prolific among sellers, that you'll have a better time finding a better price than a Verizon (LTE) one.

Then you have no service. Grab a cheap GSM phone and pre-paid SIM.
Try the yellow or the sky blue Galaxy Nexus. Those ones will work on both Verizon and T-Mobile.
Thats odd cause I have done it before

Back when verizon did both GSM and CDMA I had a verizon phone that I got to work on tmobile. I think it might have been a windows phone, honestly it was a while ago. I had to pay for a network unlock code and patch a radio or something....anyway, just wanted to say that it is in fact possible. My phone did brick in about two months, but that might have been from getting it wet...anyway...Good luck!

Total non sequitur. The phone in question must have been an old "world phone". The Verizon Galaxy Nexus never had any GSM radio whatsoever.
Also you bumped a 2 year old thread.

For the CDMA GNex you would need either a CDMA or neutral carrier/MVNO (such as StraightTalk, Tracfone, etc.). I have a CDMA ex-VZW GNex (now running Unlegacy-Android 7.1) that I am taking to Tracfone (replacing a Tracfone feature phone) because Tracfone uses a mix of carrier towers (depending on location, either T-Mobile or VZW). My current feature phone uses T-Mobile towers - because I am bringing a CDMA phone under BYOP, I have to ask the carrier (Tracfone, in this case) to create a custom SIM Kit for the brought phone, and thus have to communicate the IMEI and MEID of the incoming phone (this information is in the phone under Settings). Yes - this also applies to lifeline feature phones supplied by Tracfone/Safelink (if Safelink supplied the phone, Tracfone is your MVNO). If you want a GSM version of the Galaxy Nexus, you would want the maguro (the Galaxy Nexus in AT&T Mobility or T-Mobile guise); because GSM is more popular overseas, they tend to get exported compared to CDMA or W-CDMA (Verizon or Sprint, respectively).

Duped on eBay??

Hi,
I just purchased this phone off ebay. The listing told me that it was a Sprint phone with a bad ESN that had been flashed to Vzw prepaid.

Well I got the phone and it is a t-mobile version and not Sprint!!
I dont even know if the phone has been flashed through VZW or not. everything ive read says that the tmobile version can be unlocked, but How can I tell if this phone is on verizon or not? will I also need a sim card?
Im scared I just purchased a giant wifi only paper weight :crying:
thanks so much guys n gals.

The tmobile version is GSM whereas sprint/Verizon are CDMA. These are 2 totally different technologies. As far as I am concerned, there is no way to run a gsm device on the cdma network or viceversa. They use different frequencies, etc.
However, I may be wrong so let's wait to see if some with a better knowledge supports my claim.

My cousin(in his youthful stupidity) is with Verizon, he has a Motorola Droid(more stupidity) and for some strange reason it has a sim slot, and it is populated with a Verizon sim. I'm not sure why, maybe they do that so they can use phones that aren't normally CDMA? But then they'd need towers and spectrum for GSM. Who knows.
I actually sold an ATT S3, unlocked to someone on ebay and they tried to use it on vzw prepaid. Of course my ad said clearly it was ATT, and unlocked. I didn't think about needing to state it would NOT work on vzw. Your situation is a bit different however.

Verizon/Sprint phones are CDMA but the new 4g LTE phones from them are using a sim card slot for the 4g LTE network ... (correct me if im wrong obviously)
on side note: wonder if anyone knows how to flash the phone to verizon unleased unlimited plan $50 unlimited everything ?
Yes, the New 4g LTE phones from Verizon and Sprint have SIM Slot, and can be unlocked to use with other Carriers just like just At&t and Tmobile phones. so Sprint/Verizon phones have both GSM and CDMA chip.
Why would you buy a bad ESN phone for $500?? BAD ESN means LOST or STOLEN Phone.
You buy a stolen phone from eBay and you're surprised you didn't get what you paid for?
Stupidity.
Well being the genius I am failed to open the phone and see the huge sprint logo there. :silly:
It seems he is just running a tmobile Jedi rom and i just looked up the device id from the phones properties.
My fault guys. But not that it is a sprint phone that has been flashed to vzw prepaid. How do I activate? the MEID number that is displayed after the #*06# does not work on the vzw site or over the phone.

LG G2 for Sprint gets no love of GSM unlocks

Hello,
So I currently have a Sprint LG G2 that I would like to unlock to be able to use it on AT&T or Tmobile. From what I'v read, even the Verizon G2 comes factory unlocked which Verizon's been known to keep locked in almost all of there phones. I called customer service and told them i would be traveling overseas (they didnt ask what country) and after about 24 hours emailed me asking permission to unlock the device, they told me to go and update me UICC Unlock which gave me a message saying "your SIM is now unlocked" but when I put in a Tmobile sim card to test it, the phone would not recognize it no matter if i changed the settings to gsm/umts or global mode. What do you suggest I do next, I am worried I payed so much for the phone and if 1 or 2 years from now I decide to move carriers or even country that I am visiting to next week and the phone bieng "unlocked" still wont unlock it to be used on local carriers or even abroad, that would really suck. Any suggestions?

You really need to do some serious research.
Concerning Verizon, Verizon is required to have the GSM portion of their CDMA/LTE phones factory unlocked due to to a requirement by the FCC when they divested some spectrum a while back.
Now for Sprint, Sprint locks down (or locks out) the GSM portion of their LTE phones for domestic GSM use, so trying to use it with a domestic GSM carrier like AT&T, T-Mobile etc is out of the question by default. They'll unlock it for international GSM use (non U.S GSM carriers). Now there are some fine folks on XDA here that have been able to work around these restrictions on the Galaxy S4, but that's the exception so far.
If like you say, they emailed you that they've unlocked your phone, if you leave the country and insert a foreign SIM, it'll work with that international carrier.
Your right
your absolutly right. Now i need to find out how they did it in s4 because it has to be possible for this phone too then that case

Hmmm, this is interesting, I am having a similar dilema, as far as I was aware, I thought that unlocking would be done on the cosumer end, they would give you a code, then you'd input that code in, I've just never heard of them unlocking it on their own. I got the LG G2 LS980 when I was in the US for a semester and moved to Brazil just a week ago, I haven't tried to fully make it work, but from the LS980 manual, it says that there is not even a sim lock on the phone(i'd put up a picture, but I have no idea how). And when I try to put in an old local(brazilian) SIM card, it doesn't ask for a unlock code, it just says no SIM card - Emergency calls only. I'm still researching it, but if you find anything, just post it here so I can keep up Thanks.

Yeah I will definitely have to wait for a workaround for the sprint LG G2 as I am not a sprint customer. I think the S4 and the HTC both have workarounds, but as far as I'm aware, these workarounds apply mostly for international use only (which is exactly what I need) meaning that ATT/TMOB is probably not going to work, or might have to wait a couple months until there is a lot more people working on the sprint version, the thing is, the phone wasn't released that long ago, so support in the forums is still low.
Back during the photon days they were able to achieve domestic gsm use by flashing the radio from the Japanese version of the photon. Well maybe not directly. It may have been a modified Japanese radio but it worked!! My daughters mother still uses the photon 4g as an att go phone. Would something like that still be possible for our devices? I know a lot of people lost interest in it because after the photon we got the photon q which had an embedded Sim. Even then people were able to take the phone apart and solder a Sim tray in and unlock it for other domestic carriers.

But I think first of all it needs to be unlocked for GSM or GSM part of the phone should be unlocked for any other thing to try.

As long as some foreign carrier has their g2 unlocked for international gsm use then it wouldn't matter right? With the KDDI radio on the photon we weren't able to use sprint service on it after flashing. Basically as if the phone thought it was the Japanese version of the photon.

This would be awesome if it worked, I'm still hopeful someone will find a way, because I don't use sprint anymore and I have since moved to brazil. Thank god this phone is awesome enough to not be useless with only wifi, but I'm still hopeful someone will find a way for me to catch Brazil's GSM signal, as the phone does have the right GSM bands for it.
Just like the HTC one, it took months for even Sprint themselves to figure out how they would unlock the HTC, what I want to know if there is anyone that has actually called Sprint and asked for the unlock, and confirmed it to be working.
Can the sprint lg g2 be unlocked for any carrier.
Im trying to change from sprint contract to straighttalk. Is there a way to get my LG G2 unlocked so I can switch?

I unlocked my GS2 Skyrocket recently as I'm about to sell it and pick up a G2 next week. I popped in a T-Mobile SIM and verified that it worked. However, I very seriously doubt the method I used would work on the G2. Here's the thread though:
unlock free proceed at your own risk!
Domestic sims are too small

I called the Sprint international department and they explained the situation somewhat.
Domestic sim cards such as on tmobile and att have too little memory to support the cdma function of the lg g2, so you will get an "invalid sim" message. The size of the sim must be at least 128k to work on the g2. Maybe there is a way to get domestic network data on a larger sim card.
Hope this helps.

while the size thing may be true.. this is not why youre getting an invalid sim error. the invalid sim error comes from when u use ANY sim thats not Sprint. After you get Sprint to OTA SIM unlock your phone.. this invalid sim error goes away... gsm will work for intl.. and possibly domestic.. tho sprint may also have a block on domestic only.. after the intl unlock. if the phone is unlocked thru sprint and you pop a tmo sim in and get no signal(but no invalid sim error)... then that means the phone is unlocked properly but domestic is blocked.
this is usually my area of interest.. i did both the htc one and gs4 unlocks but I do not own a g2 unfortunately.

So are you saying if you did have a Sprint G2 you would be able to find a way to unlock it?
How the heck do they do this?
How can they unlock the phone for international SIMs and prevent them from working on local SIMs? Can't be some band that they check. Otherwise, it would not work on an international SIM using that band. Hardcode something in the kernel or the OS? In which would a custom ROM and/or kernel work? Can anyone point me to some links or posts that discuss this?

I'm also interested in this as I have a LS980 and I am currently in Brazil, sprint has done nothing yet as far as unlocking it.(even for actualy customers, I have not seen anyone that actually has this thing unlocked). I popped in a Claro(local provider) SIM card, and the phone says "No SIM card- Emergency calls only", I've tried multiple SIMs to see if it was a problem with the actual SIM, but all of them read the same thing, while inside the phone I get a notification saying "Restricted Access Changed - Voice Service is Blocked". So it knows there is a SIM card in there, it's just blocking it.

cant be 100% certain... but I'd say there'd be a good chance. Unlocked another Sprint phone this week.
Hopefully I'll get a G2 eventually.

while the size thing may be true.. this is not why youre getting an invalid sim error. the invalid sim error comes from when u use ANY sim thats not Sprint. After you get Sprint to OTA SIM unlock your phone.. this invalid sim error goes away... gsm will work for intl.. and possibly domestic.. tho sprint may also have a block on domestic only.. after the intl unlock. if the phone is unlocked thru sprint and you pop a tmo sim in and get no signal(but no invalid sim error)... then that means the phone is unlocked properly but domestic is blocked.
this is usually my area of interest.. i did both the htc one and gs4 unlocks but I do not own a g2 unfortunately.

Will give 75 $ if you can buy a used set. That's my contribution. For the G2 unlock.

SIM Card

I am going out of the country to Mexico. I have never used an international sim card with my phone. Can I use one in Mexico. My phone is Unlocked and rooted. It is Verizon CDMA.
I highly doubt it for the simple fact its cdma. Most countries use GSM. I may be mistaken but I'd check with Verizon just to be 100% sure

That is what I thought just wanted to confirm. My phone is not international but I thought it would be with a different international sim card

The reason you're phone is not "international" is because the radio chip only communicates via certain frequencies. It is a function of the hardware that is physically soldered to the logic board. Changing a sim doesn't make any phone international. Whether or not the phone has a chip that supports the frequencies that the SIM is trying to use is what determines if you'll get service.
Also, Verizon only uses SIM cards for LTE service, not the phone. If you ever get your hands on an iPhone 4 or 4S that is on Verizon, take the SIM card out. The phone will still work fine. It doesn't even use the SIM card (because 4s and 4S's don't have LTE).
You posted this in the wrong section dude
Went ahead and reported it, asking it to be moved.
No worries though. It happens!

[Q] My phone is unlocked. What I need to do next?

Hello!
Sprint unlocked my Phone. After I insert SIM card from another Carrier, I've got a message "invalid SIM Card". It there somewhere some kind of FAQ or instruction, step by step preferred what I need to do next to make it work?
Thank you!

They unlocked it for international use.
Yes. I understand! But is this possible to make it work with the USA GSM carriers? If this is possible, can somebody help? Thank you!

Not really. I had my note 3 from sorint running on tmobile. But i only had edge and slow service bad voice calling. This phones hardware bands and software bands arent really meant for it. I had to modify the carrier info in my phone to get on tmobile alone. But ince there sorint didnt work anymore. A domestic sim card unlock isnt as easy as with gsm. With gsm the carrier info is practically just in the sim card. But with sprint CDMA it in the phone. Right now sprint sims are just for the lte and spark network. Not the actual use of the phone. So youre kinda out of luck sorry.

It is strange. It can work with GSM international but have problems with domestic GSM

Ita bc the hardware is not made for it. The frequencies arent right. If you go to sprinta website the only phones they have that they can domestically unlock for any gsm are the iphones.
