Unlocking Sprint Apache?!

can this be done.. i live in a country that doesn't have that phone and i was thinking of buying it from the US through Sprint.. but will i be able to unlock it and use it on my country?? does it support SIM or not?

Why not use a HTC-HERMES
You would be better off getting a HTC-HERMES based phone. most of the US phones that are EVDO-based can't be unlocked to my knowledge. The HTC TyTN 3G Phone is better every which way than the PPC6700. I've demo'ed both units and I really like the new Hermes over the 6700. Not to mention that sprint is the one of the *worse* US celluar companies out there

In a conversation with a verizon rep a few months ago, I learned that, while not advertised, it is technically possible to activate sprint phones on the verizon network. they would need the MSL (master subsidy lock) code and a second unlock code. The MSL is needed to program the phone with the phone number itself. The second code is used for deeper device programming so that it would work on other networks. keep in mind that the rep said that it is technically possible and could not point to actual instances where it had been done.
on a side note...I think that sprint uses only one frequency mode, while say...verizon uses two frequency modes (but the one sprint uses is the same one verizon uses for voice and data on evdo phones).
my understanding is that another carrier will have to add the ESN of the sprint phone to the ESN block of their phones, which is something that may be difficult to do...you would probably have to find some kind, knowledgeable rep to do this for you.

No Verizon
I'm using verizon wireless now. Before using verizon, Please read the following:
* Not only does Verizon limit the type of "unlimited" use, it imposes a quota on "unlimited" use, and terminates customers who exceed it. According to the Washington Post.[6], Broadband Reports[7], tech columnist Robert X. Cringely, many wireless industry "insider" news sites[8],[9], and countless blogs[10]; Verizon advertises "unlimited" broadand service but automatically terminates anyone using more than 5G/month (166M/day), no matter what they use the service for. This is a quota of about 15 minutes of actual data transmission time... for an "unlimited" use account. A PBS investigator monitored his bandwidth during normal use and discovered it to be 184M/day[11]. .

This is very tue of verizon. Does anyone know if this is gonna change anytime soon?

You can get the MSL (unlock) code from the Apache by using Bitpim. Check this post:

It worked for me on a Qwest phone. Sprint still wouldn't activate it for me though.

no SIM but you can now change ur ESN see here.
~Mike

after my post above, I tried a few things...
here's what you would need to do :
change your esn (you will need your msl) to an esn that is in the block of the target carrier (hint, buy a cheap or give-a-way) change your esn, make sure that you calculate a checksum (there are instructions and programs all over the internet on how to change your esn). program your phone with your number: ##<your msl here># and type in your 10-digit phone number. don't worry about the dec or hex, just change the esn and program your number.

From Assoicated Press - Spring Nextel Agrees to Unlock Phones
I think its going to get a little bit easier, check this out:

I'll start a new thread to make sure it gets seen

You CAN NOT use a CDMA phone on a GSM network. They are completely different signals. You can unlock a Sprint phone and force it onto Verizon. You can't force a Verizon phone onto Sprint, unless you know someone inside that doesn't mind losing their job.
Again, CDMA phones ONLY work on CDMA networks such as Verizon or Sprint.

GSM/CDMA radio question

I have a question about how GSM and CDMA radios work. I have an HTC Merge from USCC (I live in Vermont, USA). They use CDMA and leave the SIM unlocked for prepaid SIM cards. I travel to Alberta, Canada on a regular basis and have access to a post-paid account on Bell Mobility (GSM). I would like to figure out if it is possible to set up my phone to work on both lines at the same time, without having to switch back and forth to check for incoming calls and texts.
Is such a setup possible?
If it is, does anyone know how I would go about getting it set up (perhaps a different thread for the answer to this part)?
On a CDMA phone, where is the carrier information stored (phone number, PRL, etc.)?
The phone is currently rooted, S-OFF, SuperCID, SIM Unlocked, running 2fastrom's USCC Gingerbread ROM.
Radio version is 1.08.00.0804
I am posting this here because I consider it to be first of all a question of whether it is possible to use both systems at the same time, regardless of the phone itself. I have added the phone info in case those who may know the answer need it. If it needs to be moved, I have no problem with that.
Thanks for your time and consideration.
All the best,
Reuben

most phones do not support both cdma and gsm

I know the iPhone 4s can use both but it has two separate antennas to accomplish this. I think it comes down to hardware.

Isn't Verizon coming up with some type of solution with VMWare for this? Where you could have two numbers active at the same time, one of them being a business number that was running in VMWare?

Yes, it is partly a matter of hardware - the Merge is set up for both systems. Still not sure if it can "listen" for two different numbers at once. Also curious about whether the phone needs to be listening to both bands at the same time if one number is CDMA based and the other is SIM/GSM based.
Verizon's solution sounds interesting - not sure it is enough to make me switch, particularly if both numbers have to be on their network.

Yes but only if you are not Verizon.

Currently Telefonica will support 2 simultaneous numbers due to a dual-sim. I really can't wait until entire networks start switching to an all IP based system. This would allow a much more flexible system then the NAM currently used.

Dual sim
It will eventually coming , we may see this type of services in near future once iphone will start shipping with GSM and CDMA unlocked version.

No its not doable at the same time

[Q] gs5 unlock? us cellular

Hey guys I'm not entirely sure if this is the right section to post this but any help would be appreciated. I have a galaxy s5 that my buddy sold me and i want to unlock it, but i called for an unlock code from us cellular, and they said i have to come to a corporate store to have them connect it to their software . I don't want to do this because it's 5 hours there one way. I don't have that much time seeing as how i work 60 hours a week .... is there anything you guys know of that i can do? :/ Any help would be appreciated! If you can try to keep it easy to*understand?

Im in the same situation. I have a US Cellular Galaxy S5 that i purchased online to unlock but i havent found an unlocking website or its only for international GSM unlock. I want a domestic unlock and I live in the middle of Arizona with no US Cellular stores.

Most unlock codes don't work on CDMA-locked devices/carriers (Verizon, US Cellular, Sprint) due to how differently CDMA phones ID themselves on a network - the SIM card is essentially only used for LTE, so a SIM unlock is useless. I haven't been able to find much hard information on it, but the process (as I understand it, someone else please correct me if wrong) involves the carrier a phone is locked to unlocking the phone, removing any codes which that carrier uses to ID the phone on the network, and handing it off to you. Think of it as a reverse provisioning.
For that reason, you're pretty much got to take the phone in. USCC doesn't want you to jump on the unlock fad and accidentally hose your phone for use on their network should you just be experimenting, so actually going in and talking to them provides a nice chance to make sure you know what you're doing and want to go through with it. I also don't think they've got the auto-unlock infrastracture in place (as opposed to auto provision).
Also, keep in mind - the CDMA S5s don't use full frequency bands like the GSM ones do. This will show you which ones the USCC one uses - http://www.gsmarena.com/samsung_galaxy_s5_cdma-6338.php - look for G900R4. You should be ok on AT&T/Cricket or T-Mobile but it looks like you'd be pretty well hosed on another CDMA carrier.

V20 and project fi

I dont know if this has been asked before, will this work on project fi?

The official list at the moment is only Pixels, Nexus 6P and 5X. Not sure why the Nexus 6 isn't still on that list since it was the launch device for the service. (I'm guessing the list is limited to what they officially have stock of.)

The US996 carrier unlocked model would be the closest match for Project Fi, but that model is missing all the Sprint bands. So would only work with T-Mobile's network for FI.
You can check all the compatibility of the US996 here:

That site says sprint's ls997 is compatible with all of project fi's bands... would it work?

Just because the LS997 from Sprint supports all the bands for Project Fi, there is no guarantee that it would be carrier unlocked to work with Project Fi and its SIM.

Just posting to add that my h910 LG v20 from AT&T does work on fi. The one guy who said that only T-Mobile would work is correct in my case. The v20 doesn't even have the type of dialer codes that are used for forcing network switching on fi supported phones. However I have found some use for this because I have an official supported pixel 2 from Project fi and happened to be a convert from AT&T and thus I had my old h910 to screw around with why the hell not? So to anyone who is familiar with project fi and is also the type of geek who frequents XDA, you are probably aware of apps like signal spy or Signal Info. When I was talking about dialer codes, those apps copy the dialer code to your clipboard and then you paste to your phone dialer which will then switch to either T-Mobile, Sprint, or US Cellular.
Basically what I'm trying to say is that even if your variant of the v20 does have the correct radios to work on the network, at this point I'm unaware of any way to switch between those Networks. That is not to say it is impossible, perhaps somebody can code something that would do that and if so please shoot a message my way. Also you may be disappointed when you find out that picture texting doesn't seem to work, or at least I haven't figured out how to fix it yet.
I currently use my v20 on Project fi very often. Anyone who has a pixel 2 is probably aware that one of the biggest complaints about the February update is reduced battery life, and so I often pull my SIM card out and stick it into my v20. Which does bring me to an interesting note if you are unaware, if you begun your service with project fi on a pixel 2 phone ....... Which does bring me to hun interesting know if you are unaware, if you be gone your service with project fine a pic so to phone.. You will have been activated using the SIM method in which your phone does not actually have a nano SIM inside of it. Now what you can do as a simple little life hack or whatever the hell you want to call it, is call and ask project fi how you go about ordering a free nano SIM. It'll cost you nothing and when you get it you can then activate it to the same phone number as the E Sim. However you cannot use the ECM and the nano SIM simultaneously. But it does allow you to have a backup phone.

Now that you can order a SIM directly from Google, will it work with Sprint model V20 if unlocked?
I realize it won't have the carrier switching but that's ok.

I too use my V20 with Project-Fi. I have the T-Mobile variant and everything seems to be working fine. The network switching will not work and will be restricted with T-Mobile service only.. Also, you will be unable to do Wi-Fi calling. Seems to be restricted on non Project-Fi phones. As far as MMS, I've used it only with Hangouts. I like to keep all my conversations synced across devices. I can try MMS via the stock messaging app and see if it works. If data doesn't work, you can try the following APN settings:
Open the Settings app on your device.
Tap More (under Wireless & Networks).
Tap Cellular networks and then Access Point Names.
Tap + (at the top of the screen).
Tap Name and enter "Project Fi".
Tap APN and enter "h2g2".
Save.
Go back to the previous page.
Select Project Fi from the list.
Hope this helps.

hi, I have LGVv20 ATT version, its unlocked. If i use google fi sim, will it work? and switch?
I am trying to not spend a lot on V35. thank you very much

Encrypting Voice and SMS?

So recently I devoted some time to do detailed reading on IMSI catchers. This led me on a hunt today to see how I could make my cellular communications more secure.
It should be noted that LTE is dramatically more secure than 3G. So one of the ways recommended for eliminating vulnerabilities is to set your device to operate on LTE only.
That being said after I set my phone to LTE only, I lose the ability to send or receive SMS or voice.
I'm wondering:
1. Is this the case for all networks or just verizon?
2. Is there a work around for forcing the device to send voice & SMS over data?
3. Is there a way to encrypt my communications to and from the cel tower?
-In researching this, I found what they call " verizon voice cypher" which is available to d/l from the play store. But is only available for use by businesses and government.
Any thoughts?
Sorry if I'm posting in the wrong forum, I think this topic should almost go in all the forums....
thanks,

With Verizon on stock Verizon/Moto firmware on the XT1254/XT1250, you can have voice with LTE. It's called VoLTE.
Verizon VoLTE does not work with Quark non-stock custom ROMs. There is no VoLTE whatsoever on the XT1225.
There is no VoLTE for the XT1254/XT1250 whatsoever on other carriers besides Verizon.
But there is VoLTE with stock Verizon firmware, so choosing LTE only should work for voice calls for you -- as long as you're in a good LTE coverage area.

thanks for the reply ChazzMatt- since this post I have found some apps that I think fit the bill. Expressly SIGNAL and WICKR ME. Do you have any experience with these? Also are there any advantages/disadvantages to using these vs VoLTE?
thanks again-
