iPhone on Sprint via international SIM?

A couple people I met told me they've been using a jailbroken iPhone with a Sprint international SIM card. Is this possible?
I know the Sprint SIM cards are for international use, and that their phones that they issue for international use don't work here in the US. But doesn't putting that SIM card into an iPhone enable it to be used n the US? Does a SIM card lock you into certain frequencies, or is it the phone that does that?
Theres very little info on this, and hte only thing that gave m hope was this closed thread at sprint users. And everyone pretty much shot him down on the idea.

umm wrong forum.
maybe you should try an iphone forum

sorry, but can you just explain how a SIM card works? does it control what frequencies you can use? or is it purely the phone hardware?

the carrier is what controls frequencies you use.
the phone can use certain frequencies but you have to find out what frequencies are possible to use and you have to make them be able to work together

so obviously the iphone is made to be used on the GSM networks here in the US. So is it possible the SIM card issued by Sprint is locked in a way that will force the iphone to not communicate with the GSM networks here?

if its international i dont see why it shouldnt

interesting, thanks for the info.

13NOV: CDMA Rhodium Q&A: GSM, 3G Bands, SIM UNLOCK, ESN, IMEI, HARDSPL, ROMS, FM, GPS
I've seen a million (not a million literally, but close enough) of these threads in all shapes and sizes around the forum, yet there still doesn't seem to be a definitive answer to everyone's questions.
Telephony Network & 3G band compatibilty
SIM Unlocks
HARD-SPL & ROM compatibility queries
Domestic (US) and International Usage
Usability of Both CDMA and GSM radios
GPS
FM Radio
As someone that shares most of the comunities queries about the Rhodium CDMA's compatibility, I am listing all the questions that I have encountered around the forum and a format in which the answers must be provided in order to eliminate any unwanted chatter in order to be able to get to the "bottom of this" ASAP.
ANSWERING FORMAT
1. Please indicate the Q number to which you will be providing your answer
2. If you are going to describe compatibilty with any service provider, please indicate the following before you start answering or asking any questions.
Name of the Serive Provider: Verizon / AT&T etc.
Country of the Serive provider:
Network Type: CDMA / GSM
3G Bands supported by the service provider:
QUESTIONS
Q1. Are the Verizon, Sprint and Telus versions of the TP2 identical as far as the hardware is concerned? The only difference I can find between the 3 of them as compared on PDADB is that the Verizon and Telus versions support only UMTS2100 instead of both UMTS 900 / 2100 like the Spint version. We need this sorted out. Is the info at PDADB not accurate?

Q2. As far as I know, ESN is used for CDMA phones and IMEI is used for GSM phones. Can anyone check to see if the CDMA Rhodiums come with 2 identifications numbers, one for each radio?
A2. Seems like it does come with both, although the ESN in this case is referred to as as an MEID
Read This
Q3. Again, as far as I know most CDMA service providers around the world offer phones without a SIM card (or even a SIM Card holder). They program the "SIM Card equivalent identification number" (maybe the ESN itself is used as identification) into the phone and that is how it identifies itself on the network. More recently, I have started to notice that CDMA phones are coming out with SIM card slots and even CDMA service providers (like Verizon) are offering CDMA SIM cards. Now multiple questions arise from this.
a. Does the Rhodium allow your Verizon / Sprint / Telus telephone number to be programed into it or do you receive a SIM card for your telephone number?
A. All CDMA Rhodium's that come from the carrier are programmed with the telephone number on them (Well it's not exactly that, but for the noobs that just means that you don't need a SIM Card.) Some users (Verizon and Sprint) receive a GSM SIM card along with the phone. That is just for roaming purposes. If you are ever in a country where Sprint / Verizon don't have a roaming agreement with a CDMA provider, then it will seek out a GSM carrier that they do have a roaming agreement via the GSM radio and SIM card. That's the only reason it's there. It (the SIM Card) serves no purpose while you're in the US.
b. Does the SIM card slot accept SIMs for both GSM and CDMA networks?
A. Ok First things first...
I'd like to correct something here regarding the "SIM" for CDMA. It's called an "UIM" or "RIM" for CDMA networks. It looks identical to a GSM SIM card but believe it or not, United States, or in North America, the UIM/RIM is integrated into the phone, where the rest of the world such as China, the users can remove the UIM/RIM just like GSM-counter parts.
We still don't have a concrete answer if the SIM slot will accept UIM/RIM cards although chances are very slim that it can.
c. If the Rhodium supports having the telephone number programed into it, does that mean that I can have another CDMA service provider (in a different country of course) delete the existing number and program in a new telephone number?
A. Of course you can. It just depends on the service provider although not all of them might co-operate and would be willing to do this. Why? Simply beacuse it might affect their phone sales.
If you are willing to do most of the work yourself, check out this thread at PPCgeeks.
Further Reading
d. Essentially, the question I want answered here is, can I use 2 telephone numbers (one CDMA number programmed into the phone and another GSM / CDMA number via use of a SIM card). I understand you cannot have both radios active at the same time and that's not what I am asking.
A. Yes, you most certainly can although I doubt youll be able to stick a CDMA UIM/RIM into the SIM Card slot and gain access to a second CDMA carrier.
Q4. This might sound like a silly question, but a lot of people including myself aren't a 100% sure about it. Once HARD-SPL is introduced for the CDMA Rhodium, can we use all the ROMs cooked here at XDA, or do we have to use ROMs that are specific to these CDMA models?
A. NO, ABSOLUTELY NOT! You cannot use a GSM ROM for a CDMA device. You might brick it! Of course if you do something silly like that, you might be able to recover it, but why do it in the first place?
Q5. Leaving T-Mobile and AT&T aside, most GSM 3G networks around the world use 900 / 2100 bands. The CDMA Rhodium (atleast the Sprint version) supports both. Does this automatically mean that 3G would work on this where ever 900 / 2100 is available? or is there more voodoo magic to this? If I understand it correctly, then this phone is exactly the same as the HTC European version (except the Front CAM) + the fact that it has a CDMA radio as well?
A. Yes, it should work!
Misc Questions
Q6. Is there a SIM Unlock tool (or any other kind of paid service / hack) available to make this phone compatible with the US GSM service providers?
A. YES YES YES! Olipro and Cmonex have made this happen for real. Works with all CDMA Rhodiums.
General SIM Unlock (for worldwide use): Read This
Sim Unlock for Domestic US carriers: Read This
Alternatively you can do the following (There's no point really with the unlocker now available)
Verizon: Call Global Services Customer Care (1. Customer in good standing can get it done immediately after purchase. 2. New customers or defaulters need to wait for 60 days) After it is unlocked, you'll have no problems making it work with any US GSM carrier.
Sprint: It's already unlocked, but won't work with US GSM carriers.
Telus: I'm not sure if Telus does that for you but thankfully enough there are a lot of paid unlocking services available starting from as low as $13.00.
Option #1: eBay
Option #2: Others
Q7. This phone seems far more superior to the International version simply because it supports CDMA and has everything else that the International version has (except the Front CAM). Is there any reason why this is not the preffered phone for ALL?
A. It's just a matter of taste and also some people really want that Front CAM from the HTC Branded Rhodium.
Q8. What is the deal with the FM Radio?
a. Is the hardware built-in for it or not?
A. Nobody is entirely sure about it yet, although based on some of the digging around that the folks over at PPC Geeks have done, it seems the hardware might be present. You can follow the development for that here. Get's interesting around Page 5.
b. If the hardware is present, then which port needs to be used as the antenna? Ext USB or the 3.5mm jack?
A. We'll find out when someone figures out how to make it work.
c. A lot of people report that it's locked or doesn't work. Any sign of a hack for it yet?
A. Not yet. There is one available for the GSM versions but that doesn't work for the CDMA Rhodiums.
Q9. GPS...
a. Is it locked to only Sprint's or Verizon's navigators or can Google maps or any other third party navigation / map software be used?
A. It's NOT locked. 2 Confirmed reports state that both Verizon and Sprint TP2s work with every navigation and map software under the sun with pretty accurate locks.
b. If it is locked, where is the hack for it?
A. Not required. It's NOT Locked
c. I'm having issues with getting accurate locks.
A. Follow the links to these discussions.

Q10. Front Camera. There isn't one, is there?
A10. Nope. No Front Camera for CDMA Rhodiums.
Q11. Headset
a. Do you get audio (stereo output) from the Ext-USB port like with the GSM versions?
b. Can an old headset with the Ext-USB connector work as a handsfree?
c. Telus comes with a 3.5mm based handsfree. What are Verizon and Sprint customers (who don't get one) doing about it?

Answer to Q9 in regards to the VERIZON version - no, it is not locked to the VZ programs. I've successfully used the GPS (with nearly instant locks) on both Google Maps and Garmin MobileXT.

Q9 GPS is unlocked on sprint TP2... All gps applications work accuratly

I want to know the answer to whether the UMTS900 in the Verizon phone simply isn't installed or if it was just an omission at PDADB.

Q4: You need to flash CDMA phones with CDMA roms. Flashing with a GSM rom will probably brick it.

Although I'd imagine that most ROM cookers will release both versions of their major releases. At least, I'd hope so.

I get conflicting reports about that.
I've read in some places that as long as you don't cross flash the Radio ROMs (GSM for CDMA), then it's ok to use the generic ROMs available for GSM phones.
Also, can anyone check on the box of your CDMA Rhodiums to see if you ahve both an ESN and an IMEI number?
What are you guys doing about the handsfree? From all the unboxing videos I have seen for Verizon and Sprint TP2s, they don't provide you with it although the Telus version comes with a 3.5mm based headset. (Not the Ext-USB one)

My answer comes from my reading when I had the VZW TP - the CDMA threads were very specific about being CDMA only (and warned of bricking if you cross flashed). The radios will be different in them - so I am imagining it will be separate still. I don't cook - so maybe one of the more experienced can weigh in.

I can confirm that too, only tried it with Google Maps though. To anyone having issue with the GPS make sure you run the QuickGPS program that comes installed while you have an active data connection. It downloads data on GPS satellites or something that makes the locks much faster than without this data.

Q8: Works. Had to install it twice (First time it said not supported) but it works.

My take on it is that, currently, we can't flash custom ROMs onto it. That's a huge part of the community here, and really, very often custom ROMs are superior in every way. Plus, you get a "new phone" feel every flash.
Once HardSPL/whatever comes out, perhaps everyone'll love the CDMA/GSM version. Who knows. In any case, Verizon's already sold out and most everyone on VZW who has one loves it, so perhaps just wait for time to tell.

Another question.
Have they in any way crippled the Video Out feature on the CDMA's?

I can confirm that the Ext-USB stereo headset that came with my Sprint Mogul works just fine.

I just bought a brand new sprint touch pro 2 but I'm looking to use it on GSM US network. I do know that it's sim unlocked and it can be used with any GSM carrier except for US carriers. I know there's currently no unlock code or app for CDMA tp2. I want to know if the phone is missing the hardware to use with GSM US carriers or is it just locked with software and if it's possible to sim unlock it in the future.

It probably just is software. The verizon model works with US carriers after you receive the unlock code.
Just a matter of time before someone here figures it out.
Also regarding the Radio. This is the PM I received from LifeStealer

I can confirm that you can INSTALL the program and START the program, but it doesn't actually pick up any stations. The interface allows you to dial in any frequency but doesn't actually pick up any signal despite the fact that it says "Now Playing".

so i got the SGS3, and I'm on Metro PCS, so I'm not about to switch carriers just to activate this phone, can anyone help or point me in the right direction to get this phone working without a SIM card?

without the sim card, it will only be a wifi phone.

You mean metro pcs does not offer the gs3 but you have one and want to use it on their network?
Where did you get it? Is it the GSM model or Verizon/sprint model.
Metro PCS works on a CDMA network (just like verizon and print) and cdma networks usually do not require a sim card but they can't use a gsm phone either. Verizon's LTE has a sim card that can be accessed (sprint's is hidden) and, according to a thread here, be unlocked to be used with GSM networks.
The easiest way imho is to sell the phone as long as it is not a lost or stolen one. Too difficult to get it to work with the carrier it wasn't made for.

it's from Verizon, i got it new from a guy on Craigslist, i usually use my LG esteem and it uses a SIM card and is on metro PCS, so i assumed with unlocking, i could simply put the SIM in the GS3 and have it working too, but in the mean time i would like to play with it as a WiFi only phone and see what i can do with it.

androids are way more than just phones, i believe your analogy is more like the processor is the the phone as the motor is to a car, the ability to make phone calls is just one of the functions, its more like a car that short-circuits while your driving, the engine wont turn off because its mechanical but you don't have the use of anything electrical , unless you use jumper cables which is what i do by activating the WiFi on my LG to use on my GS3.

Wifi only, that's it. No calls.
I think what many are wondering (after your last post) is why you would buy a VZW phone with absolutely no intention of having it activated or switching carriers just for use on wifi. You thought that "unlocked" meant you could use it on any network?

[Q] (Q) Can a LG Spectrum 2 be flashed to Page+, Boost, or used on GSM?

I bought 3 LG Spectrum 2. Now I want to see fi I can flash them to page plus, one to Boost Mobile and unsure of the options for the 3rd (Possibly use it with a GSM sim)
From what I have seen this forum is frequented by some of the brightest.
Any ideas?
What I have tried.
CDMA Workshop 3.9 (full Legit version) copied IMEI from Boost handset (purely for educational purposes) both with the LTE sim in place and without LTE Sim. To the best of my recollection it restored it back to VZW and connected and would make calls. No change. (But when I logged back into my verizon account one of the Spectrums was no longer represented by the picture of the handset just the phone number)
I have switched the RUIM only to NV Only. and nothing. Any advice, recommendations.
If this is not appropriate for the forum please let me know and I will gladly remove it.
I have seen many places that prohibit discussions of handset modification.
If anyone has info how to flash a LTE handset to use with pageplus or Boost I would like any advice where to start looking to learn how to do it.
Thanks Everyone.. Have a great Summer.

Is There a CDMA On/Off Setting?

With GSM it's easy - you take out your SIM card, and you are off that SIM's network.
Presumably the Nexus 5 will work for voice and 3G without the SIM card. Is there some way to turn off CDMA (yes, I know that if there is no SIM I can just turn off all cellular data. But that's not my question.)

If you mean temporarily, you can always do the old standby of airplane mode. Enable airplane mode, then enable whatever wireless services you want (Wifi, Bluetooth). The airplane mode will keep the cellular modem completely off.

Now that the phone has been out in the wild for a while does anyone know the answer to this question?

The N5 does not allow voice or 3g without a sim for some reason. Perhaps someone will figure out a way to bypass this check at some point.
You can also pick and choose between gsm only, cdma only, lte only etc no problem.

I don't think it is compatible with any other CDMA only provider - certainly not with Verizon. Who else is there? Metro is going GSM/LTE.
Or perhaps the SIM is necessary to pick the CDMA provider - most CDMA phones are carreir specific, and they just default to the carrier associated with the phone. In other words, if you turn on an unactivated Sprint or Verizon phone, it automatically goes to the correct carrier. If the Nexus 5 has access to more than one CDMA carrier, perhaps the SIM is the method of selecting the carrier.

PagePlus is one who runs on Verizon and allows any phone. No LTE tho with them.
Also, The carrier on most CDMA phone is determined by the PRL file. This tells the phone which towers to communicate with and it can be changed.

They will activate any CDM phone for a except few exceptions such as if the phone is ESN banned on Verizon, PrePaid Verizon phones, Verizon iphones and Verizon blackberry devices. It's a well known unofficial policy.

I guess I really don't understand how CDMA works. With GSM, if the phone is unlocked, it works on any network. CDMA always seems to involve flashing. Although I believe there is so me sort of lock on CDMA phones as well (after all, MSL = Master Subsidy Lock.) I wonder if the CDMA side of the phone is locked to Sprint (we know from other posts there is an MSL code for these phones.)

In my experience, none of the *#*#xxxxx#*#* codes work without the SIM inserted. You might even need to be activated on Sprint at the time.

Just to clarify, CDMA in this thread includes WCDMA(3g) too?
So the phone will either go GSM or LTE only, which 3g or HSDPA/HSPA are not available by options?
