On a CDMA Windows Mobile phone, how does one determine the home carrier (e.g. Sprint, Verizon)? By home carrier I mean the carrier that the phone owner has a contract with, not the carrier that owns the current cell tower. On GSM phones I can use the first 6 digits of the IMSI (MCC+MNC) to determine the home carrier. On CDMA phones this does work, because even though CDMA phones supply a IMSI, the same MNC values are used by Verizon and Sprint. On CDMA Blackberry phones I can use the home SID, but I have not found any function in RIL or TAPI that supplies the SID. I have searched the registry and a number of phones, but have not found a reliable value that determines the home carrier.
Any help would be greatly appreciated.

was wondering, if i had a vx6700..an had one of those new boost mobile unlimited plans(cdma) if i could flash it to work with their service and change the imei or whatever takes place for this(not firmiliar with cdma, use a hermes!), kinda like what a cricket subscribe would do.
you might be able to get it to work the easy way if boost will let you activate the phone on their network by ESN change. then there are a few PST changes you need to make. i got my vzw 6700 working on ampd this way... unlimited data and minutes for 150 a month.
the other way would be to clone your phone that is on boost. change ESN n some other stuff. you have to do your research if you need to go this route.
i dont know if the 6700 is compatible with the boost CDMA network.... someone else will know.
I believe that the Boost network runs off of Nextel's iDen network, so there is no way for the 6700 to run off of Boost's network.
Correct. Boost will NOT! work.
While Boost, Sprint/Nextel, Verizon are CDMA each use thier own radio/SIM that will not allow phones to interchange. This par makes us sick, especially developers.
I've seen people clone imei numbers from both verizon an sprints version of the 6700 to work wit cricket..im sure its gotta be able to be done
That may be true. Nextel's IDen network is a completely different.
im not talkin about the iDen network. boost has a new service out which is exclusivelly cdma..which is unlimited similar to metro an cricket..which is why i as asking
plz do more research b4 you reply
some of you in these post believe that the 6700 cant be used on other networks. it is true that the carrier (e.g. sprint, verizon, ect...) has specific requirements for the radio. AT&t wireless used to be a cdma network and there still is legacy cdma subscribers on their network. as for boost i havent heard of their cdma offerings. but you would need to modify the radio stack to get it to work on their "cdma" network. you can reflash the 6700 for verizon to work with sprint and vice versa. there is subtle differences that makes features work on the network.

This couldn't be further from the Truth. CDMA is a standard just like GSM is. Getting voice and text to work is as simple as updated the PRL, and changing the ESN with your carrier. I can make voice and text work on ANY CDMA phone, with ANY Carrier provided it doesn't use an RUIM, and you carrier will except CPE. You need your MSL, and a Boost PRL. Its that simple. You can use ##PRL# to load the PRL, or use QPST.
You should be able to purchase a boost phone, and download the PRL with QPST, QXDM, or BitPim.
Getting Data and MMS to work is another story, data will work if you know the correct parameters, the Proxy, username/password, and I.P. settings. Which once again can all be changed on the phone without QPST. The 6700 has full PST built in, no external programs are needed for PST changes, unless you don't have your MSL.

Really? Where was that?
They have been TDMA as long as I can remember. Thus the transition from TDMA to GSM (which is basically TDMA v2).

hi, im very new to the smartphone scene, but viewing you post gave me hope of trying to get my htc fuze to work with my nextel/boost sim. I would appreciate if you would help me with the setup. If you are available. thanks.!
You can absolutely use the ppc6700 with boost CDMA service. The only thing that I haven't quite ironed out yet is text/mms. Texting works great, but incoming messages are not stamped with the senders number. MMS works through boosts new web mms interface and my 3g works just loverly. As a matter of fact, I haven't paid my monthly bill yet, and they're still giving me 3g!
I have a CDMA TP2, I've unlocked it (had to to use it on Vodafone AU while I was down there for a month), and now I've bought an HTC HD2.
My buddy is interested in buying the TP2 off of me, but he's on Bell Mobility whereas I'm on Telus Mobility -- both CDMA providers.
When we took the phone to the Bell store, we were told that they can't switch the phone over because they don't have "Telus' lock codes".
Is this at all accurate?
No it is all about esn numbers. If they accept the esn number then it is as simple as swapping esn in the network and changing the prl to a bell one. My guess is they need the msl code for the prl swap.

So...how do I get this?
Hello...
I've been searching for a while now and can't find the answer to a simple question:
Are there differences in the Nexus S sold by AT&T, Sprint and the Unlocked versions you can purchase online? Basically, I'm asking if the Unlocked Nexus S online, which has a GSM card, can be used on the Sprint network.
We have a Google Nexus S here at work for NFC testing. It currently has an AT&T SIM card in it. But, I see it has an IMEI number under the battery.
Can I take this IMEI number and register it on Sprint?!?!
Or, are there special CDMA models sold with no GSM sockets?
Thank you!
No you can't use att or tmobile phones on sprint networks. They are a different technology. Sprint and verizon are cdma networks which don't use SIM cards where as tmobile and at are GSM networks which use sim cards. They operate in different radio frequencies. And even than its unlikely sprint would allow a different networks phone to be used in there network.

You would think that is the case, yes. CDMA and GSM (which I mentioned in my post as well). I'm very fimiliar with the differences in them.
But, someone at work broke out his Verizon Blackberry (don't know the model number) and shows his IMEI number under the battery. As well as his SIM socket with a Canada SIM card in it. "I use this carrier in Canada as they are cheap roaming."
THat's what left me baffled - a phone that was both on the CDMA network, and the GSM network in other countries.
Also, your post sounds like you are just guessing - since they are known different technologies. Do you know for a fact that the phone does not have both a CDMA radio, as well as the GSM radios (yep, two with them). THere are Japanese and Europe phones that has the combinations in a single phone, running Android.
Yes he is sure.

Hi Guys,
I'm working on a school project to research on the possibilities of sim card-less mobile technology. I am looking at replacing the sim card with a mobile application that would be able to verify the user via a mobile application.
Understand that CDMA technology doesn't require a sim card, but it is not available in my country (Singapore). Thus would like to have a discussion here on whether sim card-less is possible for GSM handset?
As the world is going LTE/4G now, would the removal of sim card obstruct us from going forward towards the LTE/4G technology?
Appreciate your replies! Thanks a million!

An app could be malicious/malfunctioning and even not contain the true credentials to identify you as the true user of the contract with your service provider. Why do you think SIM cards are encrypted?
Not sure what you're trying to accomplish. To create an app to use your phone without a SIM? What's the purpose? Are you sure you're doing this for "school research"?

Yeap, it's for a school project.
I've read that Verizon and Sprint phone uses CDMA and doesn't require SIM card. Is that true? How is the true user verified in that case?

Verizon and Sprint non-LTE devices do not use SIM cards.
Traditionally, CDMA devices in the US do not use SIM cards (Verizon and Sprint are CDMA, AT&T and T-Mobile are GSM).
Each phone has a built in identifier (called an ESN [Electronic Subscriber Number] or MEID [Mobile Equipment Identifier]) on top of the IMEI number that every phone in the world has. The phone is programmed on the computer to connect to a certain network (the APN and such are already filled in and usually not user-accessible on the phone itself, unlike with GSM devices).
Instead of swapping a SIM card, a user will go onto the website of the provider into their account and put in the device's ESN number. The device then provisions itself (known as activation) and is on the user's account.
However, all networks in the US, both CDMA and GSM, use LTE now. LTE is a GSM technology and therefore requires a SIM card to authenticate the device on the network. So even CDMA networks require SIM cards because their devices are LTE capable. Because of this, and because newer CDMA devices also support GSM (for traveling, since few countries use CDMA outside of the US), you can put a GSM SIM card in a CDMA/LTE device and it will work on GSM networks. Some networks, such as Sprint, try to counter this by artificially blocking out US SIM cards from other providers (so you can put in a Canadian SIM card for example and use a Sprint CDMA/LTE device on a GSM network, but the phone will not accept for example an AT&T SIM card).
The way everything is headed though is that everything (calls, text, mobile data) will be carried over LTE. Voice over LTE is called VoLTE.
I agree with @product F
Sent from my GT-I9300 using XDA app.
My telephone service provider (Tello), an MVNO that started with Sprint BYOD phones, is requiring me to switch to GSM.
Their customer support chat guy insists that, because their system allowed me to order a new SIM, it means that my phone (which is registered by IMEA on their system) can work as a GSM phone.
This seems... very unlikely. Even htc's web site for the U11 (https://www.htc.com/us/support/?&family=1&product=2) differentiates between their U11 and their Sprint variant.
So... am I right that the U11 does not carry both GSM and CDMA radios and that I have to get a new phone?
Thanks in advance for what may have been a very silly question.

Check your phone's "About" settings. If you see a MEID or an ESN category, your phone requires CDMA; if you see an IMEI category, your phone is GSM. If you see both (e.g., Verizon phones), your phone supports both CDMA and GSM, and may use either network.

Interesting. My U11 has both an MEID number and an IMEI number (plus an IMEI SV entry that is '0').
I wish I'd had the foresight to ask this question before I spent hundreds of dollars on a replacement phone that will takes its sweet time getting here.
