Hello fellow xdaers,
Since Nexus 5 ( and the 6, and the 5X and the 6P) has the capability to work on GSM and CDMA, I was wondering if it would be possible to work on those networks at the same time?
The existence of Project Fi keeps me hopeful about this possibility.
I am thinking of seting up a freedompop or ringplus account ( where you dont need a sim card for activation) and using a GSM sim card at the same time. Hypothetically, the phone can be used on two wireless service like dual sim phones out there.
Also marshmallow officially supports dual sim feature, it really got me thinking why not this wouldnt be possible???
I wonder all of your ideas on this topic to discuss and maybe eventually achieve 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.
World phone by blackberry? Lol

Some phones can do both. Nexus S cannot.

From what I've read, you can pop a Verizon 4G sim into pretty much any unlocked LTE capable device and have it work.
Now I'm guessing this is going to be a no, but...
I got an Airtel 3G Data card (specifically the Huawei E1731) when I went to India and unlocked it, if I remember correctly it kept swapping from CDMA and GSM signals. Now if I pop the Nano SIM I got with my iPhone 5 into this data card, (I'll try to make my self a Nano SIM to SIM adapter) is there any chance of it working?
I've also heard if things like the 4G sim being deactivated when you swap to a 3G device. But wouldn't putting it in a 3G device be the same as using the iPhone 5 with LTE turned off?
And is there any chance of Verizon messing with my data plan if I put the sim in the data card and start using it with my laptop?
I just saw a a video of someone putting a nano sim in an iPhone 4s and it working so I think this should at least work on the data card, still worried about the Verizon side of this.
Also I just remembered something about different frequencies, would the fact that the data card is from India affect my ability to use it?
Actually, I'm pretty sure Verizon SIM cards are only for their devices. I don't think they work otherwise

I've read from a few different reliable sources, don't have any links on hand. But its the phone that is locked to a carrier, not the sim that is locked to the phone, so as long as the device is unlocked and has the required hardware, it should work with that sim.
In verizons case, at the very least the LTE should work with an LTE device, I'm not sure about voice, 3G, and 2G.
In that case you wouldn't get 3G on other phones, since the SIM cards Verizon has are for 4G LTE only, their 3G networks are CDMA and thus built into the phone.
LTE is a GSM technology which is the only reason they use SIM cards at all

That is what I was thinking, but the data card seems to have both CDMA and GSM bands and when I pop out the LTE sim from my phone I lose all signal not just LTE.
Now what I'm thinking is that, since the SIM holds all the Account info, etc, not just 4G related things, that if I pop it into the 3G data card, (I've seen Iphone 5 SIM be put into a 4s and work) that it should work. That is if the Data card is compatible, which I'm not 100% sure on.
The SIM in a GSM phone holds all the account information. The SIM in a CDMA phone is for data only - the phone will work for voice/text without it. The SIMs are different software/wise.

That's what I initially thought but, If that's true than why is my iPhone 5 not able to use Data, voice, or text without the SIM inserted?
I'm not to worried about it not working, the thing I'm concerned about is verizon messing up my plans if I try using the sim in a data card.
We were able to get LTE working on the Nexus 4, abit crudely though, I read something about the Nexus 5 having an adjustable tuner, or something like that. Any chance somebody can "adjust" it to work on band 13 for Verizon?
I currently have a Galaxy Nexus, what would happen if I put my SIM card into the Nexus 5? Would it work with CDMA? It has the right CDMA bands and frequencies that Verizon uses. And if I was in an AWS band 4 area, I suppose LTE could work as well.
I know that I can pop my SIM card in any other Verizon phone, and it will work, CDMA and LTE. I don't need to go to Verizon to activate the CDMA part of the phone. So let's say I got a G2 and put my Galaxy Nexus SIM in it, it would work just like my Galaxy Nexus. So if I put my SIM card into a Nexus 5, wouldn't the CDMA just work because my SIM is there and it has the correct CDMA bands? If it does, I guess all we would have to do is get band 13 working so we can get full LTE support on Verizon.
I'm almost compelled to buy a Nexus 5 now and try this out, and hope somebody figures out how to get band 13 working.
Am I just dreaming or what?

I'd say it's easier to leave VZW.
Can you just do hacks and get the band to work?
And secondly it won't work. There have been countless posts about this. When you pop your Sim in it may take a while for service because Verizon is checking the imei on the phone to either grant it access or deny it access to the network.
I'm sure many people have ordered one and hope it will work (I have seen comments on dlife about them).
If the actual hardware components (Transceiver, Power Amplifier, Filters, Duplexers, etc..) on Nexus 5 support Band 13, maybe.
But you can't magically software enable something that doesn't physically exist.
How are you going to add the ESN to Verizons network???

Yes the actual hardware supports Band 13, this phone hardware wise is a G2 dressed in a different set of clothing and that's it. My Nexus 7 LTE works just fine on Verizon's Band 13 and my IMEI is not in Verizon's database. Now Verizon wont activate a sim in a device that isn't in their database and Verizon CDMA has always been unlocked. I am betting money if you take a sim out of an iPhone 5 and live/visit a market where Verizon is doing LTE on AWS and pop that nano into a Nexus 5 your gonna auth on the LTE network and your gonna be working 100%

I currently have the Galaxy Nexus and Nexus 7 LTE. The Nexus 7 LTE's IMEI is not in Verizon's database and it still works when I put my Verizon SIM into it, and it does not take it a while to get service.
I understand things are different with CDMA, but I still have a sliver of hope that somebody will get this working on Verizon.

Same sentiments except the Nexus is micro sim so you would need a converter. Band 13 is controversial because VZ has a consent decree to allow open device access but other bands are not covered. Since Band 13 is not enabled a hacked modem FW need to be installed to enable as such. The Nex 7 LTE does not support CDMA nor Voice so that is not exactly the same.
BTW my S4 now shows Band 17/20 support with the new MJ7 Modem update.

IMEI can be activated by Verizon

Okay so non-vzw device is actually a common issue. It is completely possible to activate a non Verizon device on the Verizon Wireless network, thought it's not something we advertise, and chances are you if you ask us if it's possible we will give you the blanket answer of no because many phones designed for other carriers are locked to that carrier, it is possible to unlock it for activation on another network (eg AT&T iPhone on Verizon network) but it's not something we do. When we receive something that the system does not recognize (it can only be done by placing an active sim into a new device) we have to fill out an e911 compliance form and manually add the MEID/IMEI to the system, tech support is capable of doing all of this upon request.

FYI: I have a Nexus 5 on latest Marshmallow update and it runs great on the Project Fi network after I activated the SIM in my Nexus 6.
Thought I would try this to answer your questions.
I have an activated VZW SIM which I swap out to many other devices, including the Project Fi version of the Nexus 6 (Non-VZW device), a Droid MAXX, GPE HTC One... and many unlocked tablets and MiFi hotspots without issues (so long as the bands are supported).
I popped the VZW SIM into the Nexus 5 and it recognized the SIM but showed no network service. I attempted the pre-configured VZW APN settings to no success. I then manually entered all APN settings from the Nexus 6 which works fine. Nothing... no service.
While you may be able to get VZW to manually add your IMEI to their E911 database, I doubt it's worth the effort.
In Short and to re-confirm all of the previous posts... NO, you cannot use a Nexus 5 on Verizon wireless.
I recommend you go pick up a 5X and it'll work straight up out of the box.... or sign up for Project Fi. I love Fi but keep my VZW for the unlimited data.
I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
Recently revived my N5 that had been sitting around due to my N6P showing some water problems in case I needed to switch phones quickly.
Well, after resetting and installing AOSP Extended, I put my T-Mobile sim in, and gets no signal. It will recognize a sim is in, but I get no service at all. I figured something could be wrong with the simreader, so I tried some other sims. Sprint sim and a Freedompop(AT&T) sim both work. I know my T-Mobile sim works, as I'm currently using it in my 6p. Anyone have any solution?
freedompop uses at&t for GSM devices and sprint for CMDA devices. it sounds like your phone is the CMDA version, and your using the sprint network with freedompop. T-mobile is a GSM network and will not work with CMDA phones.
