[Z1s / C6916] Possible to SIM unlock this phone without acquiring an unlock code?

Hey guys.
My girlfriend pain-puked on her Galaxy Nexus, so I'm gifting her my old Z1s. Her carrier and T-Mobile use nearly identical wireless bands, so it'll be perfectly compatible. Unfortunately, it's T-Mobile locked, and she's on Wind Mobile (Canada).
I bought the phone used, and the old owner hasn't paid off their balance on the phone, so T-Mobile is being completely worthless.
There's all sorts of options for buying an unlock code, but these places want to charge me $40 for a code, which I think is pretty ridiculous.
Is there any way to unlock the Z1s without having one of these codes?

Threw up out of pain, went to the hospital, found out she had a kidney infection and definitely shouldn't have waited.

SOLVED:
T-Mobile was happier to SIM unlock it under the guise of 'international travel'.
Try that!

Unlocked?

They unlocked your Z1s? Did you lose any of the features? Are you able to install a custom kernel?

unlocking the Z1s c6916
I have the Z1s unlocked and it is very good phone but i did it using the unlock code , Though I didnt want to hold responsibility so i made my friend do the job .
See if a local mobile services shop can unlock it for you BTW you have limited attempts so be careful after you use them up no other way of unlocking available .

[Q] Will my Unlocked Sprint S4 work with a Verizon prepaid SIM?

I have been doing research and searching these forums for a few days now, I'm trying to not be one of those people who ask questions that have been answered. But at this point I'm at the end of the road.
I bought a Sprint Galaxy S4, model SPH-L720.
I unlocked it using this method Sprint Galaxy S IV SPH-L720 SIM Unlock Method
Reverted back to MDC baseband and all that good stuff, just as instructed. It seemed to have went well without a hitch.
My question now is:
I want to buy one of these Verizon 4G Sim Activation Kits from walmart
Is it possible that I can buy one of those, insert the SIM into my unlocked Sprint S4, and have a working phone? I ask because I don't want to drop $50 if it doesn't have a chance of working. The instructions for this say that it will work with a VERIZON S4, but since my SPRINT S4 is unlocked, should that be okay?
I don't know much, but in my reading I found that Sprint and Verizon both use CDMA, not GSM. So I figured I had a better chance of this phone working if I go with Verizon because of this.
I am in the United States.
If you need any other information or screen shots please let me know, thank you for taking the time to help me out!!
EDIT: would it be possible to test it out, if one of my friends has a verizon phone under contract, and I took their SIM and inserted it into my phone?

Try it.

Like the guy above me said. Try it. One way to find out. Personally I don't think it would work. As the whole point of unlocking the sprint Gs4 is to use it on GSM networks. From what I know you have to flash the sprint phone to Verizon. Plus you WONT get LTE on Verizon because the bands are not supported. So you'll only get 3g.

thank you for the info! i'm just learning about all of this, so i don't have a firm grip on everything yet.
in the tutorial i used and linked above, the file I used with Odin was actually titled "S4 Flasher", so I believe I unlocked it and flashed it with this? Again, Im sorry, Ive tried searching and am just looking for verification if Im correct.
I'm not worried about LTE, 3G is fine really. Also, I'm not set on Verizon, I just want my phone to work, doesn't matter what network I'm using. If it would be "safer" or a better bet to get into a GSM prepaid, I will do that instead. I was just under the assumption (incorrectly probably lol) that since sprint is CDMA, that going to another CDMA carrier would be easier.
Cricket, Net10, StraightTalk, and AT&T etc are all available at the store I think if I go GSM
Again thanks for taking the time to help everyone!

I unlocked my sprint GS4 and went to Cricket. And I've been happier than when i was with Sprint (service wise). I have signal in 98% of the places I go to. Which is a HUGE improvement over sprint. And even though this phone only connects to HSPA+ which is capped at 3.5 Mbps its plenty fast for all my daily activities. So I recommend a GSM prepaid.

Unlock Sprint GS 7 for use on ATT/T-Mobile

I want to purchase a Sprint GS 7 and sim unlock to use on GSM carriers like AT&T and T-Mobile.
What is the process official and other options for sim unlock.
Never had Sprint service before, thanks for your assistance.

First step is to not stick a sprint sim card in the phone. I played around with mine without a sim card and to get the stupid vr game promo i stuck the card in and next thing it did was install all the carrier garbage bloatware automatically and it changes the boot screen and to my understanding it sim locks to the carrier that the sim card uses. Complete bullsh!t I am irate and stuck with all of this garbage bloat courtesy of sprint and the locked bootloader thanks to samsung. Im returning mine

I bought my sprint s7 full price through best buy.
First thing I did was swap the sprint Sim with my AT&T Sim (testing first Sim inserted). Prompted with invalid Sim error.
Appears the sprint phones come with activation software pre-installed that locks it to their network. You need them to unlock it from their end, no unlock codes.
When I put the sprint Sim back in, it didn't install all the bloat. It installs everything if you activate the phone; unactivated Sim, no account.
According to sprint, the phone needs to be activated on the network for 50 days and paid in full to be unlocked. They unlocked mine without meeting those standard because of poor support from a rep before I bought it.

After you get it unlocked, you can just insert any sim (gsm/cdma) after?
I don't see any settings to change the network mode.

I'd like to know the same. I'm traveling over seas in less than two week and would like to use while over seas with the local carrier. Not so much concerned with using it with other carriers domestically though.
I'm also curious if the phone can be used for data on other carries once unlocked. I wonder because with my current Sprint GS5, Sprint unlocked it, but it does not work with data when over seas. Come to find out after a lot of research, there is no solution and everybody with unlocked Sprint GS5s also cannot get data to work without wifi.
OP, you may want to keep that in mind and do your research. If Sprint's GS7 is like their GS5, you will not be able to get data on the phone with other carriers even if unlocked, unless connected to wifi.

Yes, any Sim CDMA or GSM will work. And data works perfectly for me. The s7 is the same device for every carrier where the only thing that changes is the software.
Here's a screenshot of my sprint phone on cricket with data.

With the Sprint model, there will be LTE issues overseas depending on where you go and which carrier you use.

I went to UK in 2013, had my S4 with me and was able to get data. I was not, however, able to get fast LTE speeds. Sprint cripples their LTE bands on purpose for some reason so that they become less useful on many international carriers.

The main difference between models on each carrier are bloatware they add and LTE bands they add and delete. Sprint always gets rid of useful LTE bands like LTE 7 which is a popular worldwide band.

Correct. Cricket is owned by AT&T, a carrier who did not get rid of band 7, despite the fact that they use Sprint's 3G network as well as CDMA. Do you have bands 25 and 26 as well? If so, that would be great!

You're also correct but this is a Sprint S7 network unlocked. And yes, I do. 25 and 26 are the first priority for me.

Interesting. Okay, so do you *also* have LTE 29/30/40 that AT&T has been adding to their phones?

I don't actually. Knowing this I'm going to focus on attempting to add these bands (toggle them). Trying to get a hold of Sprint currently to get my MSL code.

The Galaxy S7 is DUC meaning it can be unlocked for domestic use, and it will automatically unlock tru a programming update sent OTA after the device has been active on the account(in good standing) for more than 50 days.

For those not in good standing, or who don't feel like waiting, find somebody with a Z3X-box, like myself, on craigslist. $45 (or usually in that area,) takes us 5-10 minutes, don't need root, and doesn't need to be clean. =]

##3282#

Just bought a sprint s7 yesterday since it was cheaper for me and had it unlock from an ebay listing for about $15. It was quick like 2 minutes and easy. Its done remotely on the person's end with your phone connected to computer. I'm using it on Tmobile and is working great. I get lte speeds and call quailty is great. Getting to the service menu above ##3282# you can edit the band priorities so you can have the wanted bands 1st, 2nd, and so forth. Just need the MSL# which they can get you.
If this is against the rules sorry, but just thought I give my experience with unlocking the sprint s7.

I'm trying to find detailed specs without luck, can someone please clarify which LTE bands the Sprint variant of the S7 has?
Please list all that are physically on the radio, and specify if they are actually available for use or blocked.

Should I leave it as a Verizon variant or convert it?

Hello,
I just moved back home to Guam a few weeks ago from Colorado and I am wondering how I should go about getting service in Guam.
After I pay off my Wife's and I services with Verizon I want to try and connect it with the carriers here. To my understanding, after I pay Verizon the early termination fees etc, the phones should be unlocked*carrier unlocked*?
The phones in question are the HTC 10*mine* and S7 Edge*wife's*, we spoke with Verizon before we left, they told us that the phones are unlocked already and wouldn't have any issues using other carriers.
Should I change the HTC 10 to the Unlocked variant is this even possible? I've read about unlocking it to T-mobile or ATT etc so should I leave it and see what my local carriers can do or should I get it in an unlocked carrier state?
Before we left I used a Sprint variant of the M7, lots have changed since then, I didn't have to do anything to change the MID etc, I was sorta gimped on Data connection, but that was a few years ago, NO 4g LTE, but now the local carriers are on it.
Thanks for your time

If you stay with Verizon, keep the stock software. Also you're already sim-unlocked.
If you change to a GSM carrier, not sure the VZW software will work or not but you can definitely "convert" it to the U.S Unlocked version. That's the easiest/safest way since both phones have the same MID. You'll need S-off ($25).

I am S-off already.
Would being U.S unlocked be a viable option to not have issues trying to connect with local carriers?

First, great info above me. 2nd, you could actually go ahead and superCID and run latest 1.96.617.20 US Unlocked RUU. I'd say the best method is to try them out, RUU or firmware. If on a custom ROM and say chose VZW, you'd have to flash again and chose US unlocked. If you are on stock ROM then I'd try and see if it works as vzw says. If not I'd flash The Us unlocked firmware (modified for vzw you may need the radio.img and cardio.img that is normally removed). Best of luck my friend. I hope all goes well!

Will I have issues flashing viper after SuperCID?
OR should I go down to my carrier and try my luck as the device stands?
Thanks a lot!

No issues at all. Supercid, basically makes it so you can flash any firmware and other things like RUU from other carriers like us unlocked -- (so make sure you know what you're flashing!!!) .
I'm not sure of your carrier or what they'd say. I'd honestly play it by ear and see what happens. I have faith that with the 10 you will be able to get everything working; although I can't say for sure.

I'm using a Verizon phone flashed with Unlocked ruu on a GSM network. The conversion improved the phone for me. Better reception in my area, able to connect to more lte bands, txt msgs come/go faster, and the initial connection to the network after boot up or getting outta airplane mode is much faster since I got away from VZW stock software. Also you get OTA updates as they become available, and you don't have to deal with Verizon's worthless software modifications like no battery saver mode, Wi-Fi notifications, etc if you're gonna stay stock.

Flashing the Unlocked firmware is your best bet. The only thing I'll add is that if possible find out what bands are being used by the carriers over there, and see if its compatible.
HTC 10 Unlocked Band Support:
LTE Bands FDD 2,3,4,5,7,12,13,17,29; 2G GSM/GPRS/EDGE - 850/900/1800/1900; 3G UMTS - 850/AWS/900/1900/2100; LTE - FDD - B28/B12/B13/B17/B29/B20/B5/B4/B3/B2/B1/B30/B7.

I want to convert my verizon htc 10 to international version
Guys, do you know how can i possibly convert my Verizon HTC 10 to works the same as the global unlocked phone? I'm so sad with the verizon version, I got weak signal in my country and barely reach to 4G LTE network. Most of the time I can only use 3G and some features also not work I'm trying to read lots of forums and watch youtube, but still couldn't get what I want! Plz let me know.
Thanks in advance :fingers-crossed:

It's going further than it did the other time..
It gave me error 155 and 170.. even with a full battery...
So I can just RUU the U.S Unlocked version and and try and use the radios, if not I can just flash back the VZW RUU with no ill effects?
SuperCID to 11111111....

Possible to use a Sprint HTC 10 on Verizon with unlimited data & hotspot?

Hi all,
I didn't see anything from reading through the forum on using a Sprint HTC 10 on Verizon. It sounds like there's been success with Tmobile and AT&T.
So far, this is what I've found:
-Sprint HTC 10 should have all the LTE bands necessary for Verizon
-Sprint HTC 10 needs to be sim unlocked before anything can be done
-S-Off + root are required for any potential workaround for Verizon, as the appropriate radio needs to be flashed
How far off base am I? I am intrigued because I am on Verizon and I'd like to take advantage of the sprint HTC 10 sale that's supposedly going on right now. Thanks in advance!

I have the same question. I'm trying to jump on that but for T-Mobile. I'm just worried I won't be able to get the device unlocked.

Historically, Verizon and Sprint don't activate each others' phones. They're the two big CDMA carriers that don't use SIM cards, but activate by ESN directly. But there are always those who get lucky.

? anythin

I've been working on that recently. I actually want to be able to switch between Sprint and Verizon.
Sprint has to activate both the phone and the SIM. Verizon has moved to just using SIM cards. I've been able to move a Verizon SIM between devices and have everything work, even on devices that aren't official Verizon devices and even some that only support part of the bands Verizon uses and work on the ones they support.
With the HTC 10, I've been able to get S-OFF and unlock the phone myself since Sprint wouldn't do it. When I put in my Verizon SIM, it recognizes it but for whatever reason is unable to connect to anything but 1X Roaming (probably on Sprint but it won't say). Poking around in CDMAtool hasn't helped much.
I'll update this if I ever figure it out.

Any updates? I'm curious myself. I have the Sprint HTC 10 and am working on finding an MVNO that I like, some of the Verizon ones are tempting.

By perfectly do you mean volte and Wi-Fi calling are working for you? If so please point to the guide you used. I can't find where anyone using a sprint 10 has gotten those things on T-Mobile.
I would be surprised if a sprint 10 used on Verizon would have that work too but haven't seen any mention of it.

I unlocked the bootloader and installed ViperRom, picking the US Unlocked version as my device. I have working VoLTE, but not wifi calling. (Note, this is on Mint Sim, which uses the T-Mobile network)

yeah it would be great if someone could give a for sure answer to this. I've found a lot of post giving conflicting information all over xda and r/htc10 about this. I would love to buy a used sprint htc 10 (seems to be the cheapest version by far) and use it on a verizon mvno, but until I know for sure it works I' not going to do it.
