How to enable CDMA on Nexus 5 (US)? - Nexus 5 Q&A, Help & Troubleshooting

I received a Nexus 5 from US about three weeks ago, and have been using with the GSM network of BSNL. A friend of mine works for MTS, a CDMA network, and I got a SIM card from him, and inserted it. But the device doesn't detect any network. When I search for networks manually, it shows the list of GSM networks available.
How to use the phone in CDMA mode?

You can't, the phone is a GSM phone not CDMA

the nexus 5 works on sprint as well as GSM carriers.
as far as the OP, i'm not sure what youd need to do to get it on a CDMA carrier outside of sprint

How am I meant to know when I'm in the UK with a D821? Old CDMA handsets are different from GSM phones, hence why there isn't a Verizon Nexus 5
And being a RC doesn't mean I know everything, nor I pretend to do so. If you wanna try and get one up on me you're gonna have to try harder

He might have not noticed that it was about US version of Nexus 5 (which I mentioned in the parenthesis). I thought, after reading his post, I should have posted it clearly in the post description.

I noticed it, but assumed it was only the 4G bands that were different. Again, this was based on knowledge of previous Android handsets where they weren't GSM and CDMA at the same time. We don't have CDMA in the UK so I have little to no knowledge of it

No worries, mate. Take it easy. This is the first phone I know which has a single slot for SIM cards and supports both GSM and CDMA.

well, a lot of the (newer) verizon phones have SIM cards, support both GSM/CDMA (iPhone 5/s, Droid DNA, S4)..
however, since few providers use CDMA, they are mostly on this side of the globe released by verizon, and verizon might have disabled USA sims on that sim slot unfortunately
@ OP, take a look at this hack to see if it'll work with your provider

Web Surfing while Talking

I know this is an odd request, but is there anyway to use the internet while talking on the phone. Normally I wouldn't care but I'm tired of the iPhone goons hassling me about it since those new commercials.
If not would there be a way if I unlocked my phone for GSM so I could talk on one frequency and surf on another?
Please direct me to a link if this has already been answered, I searched and didn't find anything.
Whoo boy, the old GSM vs. CDMA debate. No to your first question; it's a technology limitation of CDMA, which is why AT&T loves flaunting that fact. GSM also has the leg up in the number of simultaneous connections for conference calling. If you're looking for ammunition, CDMA generally enjoys better penetration of structures, and I know that I have found my service on Sprint to be stronger and much more reliable than my old plan with AT&T. Some people would even say that CDMA offers better call quality than GSM, but that's a huge debate with opinions on both sides. Also, GSM's encryption method was cracked recently, making calls potentially more vulnerable to eavesdropping. Finally, even when I had my old Tilt on AT&T I don't think I did too much surfing while talking on the phone; I really don't think it's as amazing a feature as they make it out to be.
For your second question, the CDMA Worldphone edition Touch Pro 2 used by Verizon and Sprint does have a GSM radio, but the question has been asked before if both networks can be used simultaneously and I believe the answer is always no. Anyone else feel free to correct me if I'm wrong.
last I checked in order to use cdma/gsm phone networks at the same time can't you just pop in a sim card!!!!!

one word IMPOSSIBLE!!!!!!!!!! GSM and CDMA are hardware radios an unlock is IMPOSSIBLE unless the phone is a world phone with both CDMA and GSM but your phone doesn't qualify so try getting a GSM/CDMA hybrid and then come back to me. However verizon will upgrade to LTE which is GSM based!!!!!!!! watch em LTE will allow voice and data at the same time. When LTE upgrade is complete say goodbye and good riddance to CDMA it will be shut down soon!!!!!

qjsmartphone - I thought that the TP2 was a world phone and thus held both antennas for cdma and gsm?
trogdor1138 -thanks for the input.
now I'm with sprint, and they offer 4G. This may be an ignorant comment, but can't a world phone with both antenna's say call on cdma and use the 4G provided by sprint? Or am I missing something? I kind of new at this so forgive the question if it is stupid. If there is a wiki on it please give me the link and I will be glad to read up. Thanks

I'm not sure what you are talking about, but CDMA variant of Touch Pro 2 does have both GSM and CDMA hardware in them.
Also, LTE and WiMAX is a two new 4G technologies that will eventually replace 3G data.
LTE is not based on GSM, they are two different communication technologies.
Back to OP's question, if you are using CDMA branded TP2 you cannot surf and talk at a same time. It is limitation on CDMA technology.
4G and 3G is not compatible, is your grandparent's old 2G phone do 3G? no.
How about your 3G phone accesing 2G? yes. Usually when newer technology is being deployed, they make sure that it is backward compatible, so that they can lower battery consumption and remain accessible to area where new technology is not yet available.
Just be near wifi and then show them you can surf while talking.

Or pop in a ATT or T-mobile SIM card and switch to GSM mode. The phone IS capable of voice and data when using GSM.

I thought Sprint/Verizon phones with both GSM/CDMA radios cannot use AT&T nor T-Mo SIM cards. I thought they only accepted the GSM SIM cards of countries outside the US.
Wait... HardSPL fixes that, doesn't it?... Oh well, I think I should stop stalking the CDMA forums when I have almost no idea on anything CDMA-related!
But, I'm still in favor of the WiFi suggestion!
mac people live in their own little world. don't let them bother you. sure, they can talk and surf the web at the same time...if they have 3g coverage. but there are areas where they have no coverage at all let alone 3g. then they can use the 'paper weight mode'. i also love how they tout their app store meanwhile we've had multiple wm app stores for years already. also i get to choose what apps i want to use without htc or sprint telling me what i'm allowed to.

i think you can use any SIM card you want if you phone is SIM Unlocked
yes you can use any sim card if your phone is sim unlock buy the Sprint TP2 is not working with us 3G
unlock
I called up VZW and told them I was going to Europe and wanted to use prepaid SIM cards instead of paying Big Red the $$. They gave me the SIM unlock code and now I can use T-Mo or AT&T SIM cards with no problem. Only downside is that their GSM frequencies are slightly off from the rest of the world so no high-speed data when using VZW on GSM carrier in the states...

The CDMA Touch Pro 2 *is* a dual mode world phone with both GSM and CDMA.

The Verizon TP2 has a simple SIM lock on it which is similar to standard GSM SIM locks. Remove the SIM lock and you can use any SIM card with a compatible network, including US networks.
The Sprint TP2 doesn't have a standard SIM lock, but instead has the US frequency bands disabled. Hence the need for a new radio.

[Q] Nexus S SIM unlock?

Hey NSers.
I bought a Nexus S just about the week it came out from Best Buy, but I've decided to move on to another phone. I had thought that purchasing it from Best Buy meant that it shipped unlocked, with no specific carrier, but I just tried an AT&T SIM card in the phone, and it gets no service.
I called T-Mobile, but the woman I spoke to informed me that they couldn't request an unlock code because it's not a phone they actually support.
So I'm wondering how I can unlock it.
Right now, its bootloader is unlocked and it's rooted, if that makes any difference (I'm hoping there will be something easy I can do that doesn't involve contacting either Google or Samsung).
Thanks in advance for any guidance.
your nexus s IS unlocked as of google phones.
the problem is that the nexus s does not support (hardware) AT&T cellular bands.
there is a specific model of the nexus s (I9020A if i'm not wrong) that support those AT&T bands.. sorry.

Oh, really? I thought it supported AT&T GSM bands, but not the 3G bands.
And no worries. It's an i9020T, so maybe it's unlocked but still works only with TMo. Darn.

Right. But if I put in an AT&T SIM, it should work with AT&T's GSM frequencies, right? I'm really not looking forward to calling Samsung tomorrow.
I should go to best buy and ask if you can swap it for a i9020A.

I9029A isn't sold in best buy. I'd go to AT&T and get a new sim card. Your phone should work just fine on AT&T, u just won't have 3G.
I've had a similar experience with the Canadian carriers, however if the carrier supports GSM bands it will work (like previously said) it's when the carrier only supports HSDPA (like Koodo in Canada does) then you need the specific Nexus S (i9020A in your case).
You could also try adding the APN to see if that will allow you to connect (Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names (APN)) - the details can be found on the forums / your carriers website.
Works for me.

Works for me. I live in NYC, and I picked up a Nexus S at Best Buy over the Easter break as a quick temp phone till I got my Captivate fixed.
No 3g, but it certainly works on Edge. Makes calls, data works, syncs with google apps, etc.
Maybe you're just in a poor reception spot for ATT...
Thanks for the advice. Will retry. I'd wanted to confirm AT&T would work before I put it on eBay.

Verizon GS3 "World", "GSM", or ???

The GS3 Verizon is a CDMA device. Supposedly it has GSM compatible radios too. It's supposed to be able to work on GSM networks after a software update coming soon. Does this thing have a sim card slot? I don't see how it would work on GSM networks without it. Does anyone know how this works?
I'm hoping to use it on Verizon in USA, but on Telcel while in Mexico BUT with my Telcel sim. I realize my hopes are slim but if there's a sim card slot maybe it's possible???
Thanks.

Actually, I have an old Verizon Motorola Z6c World Phone here that I bought in 2008. It has a Verizon sim card inside.
Z6c Specs say:
2G Network GSM 900 / 1800
3G Network CDMA 1xEVDO (800 / 1900 MHz)
Anyway, there's no LTE involved on the Z6c back then. SO apparently the GS3 will need the sim on non CDMA networks. I just wonder if the software experts here can make it possible to use the sim only at certain times and at the same time unlock the phone.
A lot to ask but will be a huge feature if done.

I said earlier that I wasn't sure about compatibility, but I'm starting to believe that this is not possible, as the Verizon version lacks the proper GSM/HSPA+ radios. There's a model comparison chart that you can expand on the Wikipedia page. Software probably won't be able to pull the miracle you're asking for. Sorry
http://en.wikipedia.org/wiki/Galaxy_S3
Maybe this will help? http://androidcommunity.com/verizon-may-enable-global-roaming-on-lte-phones-soon-20120518/ from what I gather LTE is based off of GSM and its just a matter of unlocking the GSM bands on the phones.

Yeah, I don't think the current specs out on the GS3 are totally complete. If the phone is admittedly needing a software update to allow the GSM roaming then they can't just put those bands in the specs with no caveats.

Motorola Xyboard 10.1

No, different carrier types, att is gsm while Verizon is CDMA.
While vzw does use some gsm for their lte it is not the same frequency so it will not work.
Sorry mate
I believe the xyboard has the same chipset as the Bionic so in theory the surprisingly easy hack to use the Bionic on gsm (US AND global) networks could likely work.

The Droid Xyboard has both GSM and CDMA radios.
But GSM will only work on Non-American carriers, its blocked for AT&T and T-Mobile (I tried - didn't work).
Hypothetically speaking though, even if it did work on AT&T it would still not run on AT&T's LTE (only HSPA+) because it doesn't have the LTE frequencies.

AT&T runs on GSM band while Verizon runs on a CDMA network. I'm surprised your SIM even works. What other said is correct though, you are restricted to the slow 2G Edge speeds.

Well the S3 is a World phone, hence it comes with GSM bands too! if you hit Europe or Asia you will get 3G

Right it does. But they use different bands in other countries. Our phone isn't capable of using any and all bands. Only certain ones. If somehow these bands were unlocked, then you could get 3g here.
