[Q] Nexus 4 in China - Nexus 4 Q&A, Help & Troubleshooting

HI all,
I'm being moved to China through work. I'd like to take my Nexus 4 with me. It's an off-the-shelf phone, meaning I haven't rooted or done anything to it.
Will it work in China if I buy a local SIM?
Thank you for your assistance.

I dont know a reason, why this shouldnt work in china. Take care and check your food twice. Dont want you to expereince 'hot dog' or something over there

Yup, as long as your chosen carriers uses one of the frequencies the N4 works on you'll be OK.

I come from China. And I'm using China Unicom 3G sim card with my N4.

Hey There,
Great Post. Seems good to have people already sharing useful information like that.
As a personal request though. Your signature size is a bit unreasonable. Could you please consider resizing or doing something else about it?
Thankyou
I want one if the price difference isn't too bad.
dual sim card sounds interesting, I'd have no need for it though. lol deftone
If it has the same specs as the Note II this will be a dual sim 3G world phone. Are there any other Android dual sim 3G world phones out there?
I wouldn't have a need for one but I guess it could come in handy if i wanted to put a prepaid sim in it.

Maybe, look on Google for ROMs for a regular device with a dual-sim variant. For example, the Galaxy Pocket and the Pocket Duos. They have the same specs just like the Note 2 and the Note 2 Duos do so look to see if anybody has flashed a Pocket ROM on their Pocket Duos. If they did, then I guess it would work.I think you can probably find it in a couple of days. Or you could order from China Mobile, the carrier with the device, and have it ship to you.

Dual SIM Note 2 would be awesome for a backpacking holiday. Local SIM as primary, with home SIM as secondary with its super expensive roaming charges. Each time you change country just swap out the primary.
I wasn't sure about Note 2 vs Note 1 but with 64GB internal, 64GB SD, dual SIM and Seidio case with kick stand and holster it will be an iresistable killer combo
Adding decent GPS App with locally stored maps and an external range boosting antenna would make it the ultimate travel phone

Sounds Good!
does anyone know what dual sim entails? can you have 1 sim for mobile broadband (with telco provider a) and 1 sim for minutes, SMS (with a separate telco provider b)?
both reading at the same time. the note 2 knows which one to use and when? so you don't clock up data on the wrong sim, and calls and SMS on the other?
thanks
The "classical" Samsung DuoS phones (at least mine and others I had in hand) let you choose a primary card that is used for everything by default and a special button that allows you to choose the secondary SIM card before making a call or sending sms. Web connection and other services always run from the primary card. Changing the assignment of the primary card causes a reboot.
Both networks are actively receiving calls/sms.
How this one is (or would be) done is hard to tell, not many people had it in hand (if it really exists). Unfortunately, probably not many people ever will.
Personally, I need two networks, so I carry a "phablet" without SIM plus classical DualSIM phone. DuoS Note would be cool.

No, i don't think so.
so year 2012 and they can't even do what seems to be simple. one uses data, other using everything else. option in an app lets you choose what what simcard does? zzzz

[Q] Quick question regarding buying from the US

Hey guys. I finally decided that buying the Nexus 4 is my best bet. I also have a friend that would bring it to me when he comes to Europe. So my question is: Will I be able to use the US version normally here in Europe? I have a contract at a GSM provider, will there be any issues? What about the power socket?

I'm 99,9% sure you can. The Nexus phones are made to work on almost any carrier in the world.
To be 100% sure, just search in google your carrier 3G bands, like 900, 1200, etc. After that check to see if they match the Nexus 4 specifications.

[Q] Baseband Version doesn't matter that much (for me)... right?

Hey guys. I saw a Nexus 4 (16GB). It had the baseband version of "m9615a-cefwmazm-2.0.1700.33"
I live in Pakistan so i have no 3G/4G/LTE (yup we're that backwards!)
This phone couldn't detect my 2G operated SIM Card :/
Where it detects and worked well with my Galaxy SIII
Still haven't bought that Nexus 4 (buying it 2nd hand).
A person confused me in saying that is was a "CDMA PHONE AND IT CAN'T WORK WITH UR GSM SIMs AND ROOTING/MODDING WILL CAUSE PROBLEMS"
Is he telling the truth? This phone was actually a bargain for me and had no problems whatsoever in the Hardware/Software wise other than the above
Can someone please elaborate this? thank you

He is completely wrong. Nexus 4 is GSM only, with no CDMA variant. If your SIII worked, I don't see why the Nexus 4 wouldn't. It appears to be running an older radio firmware, maybe updating it to 4.2.2 would help.

Pretty much this. Try flashing a newer version of the radio.
Maybe your friend was right (backwards, but right). Your carrier might be CDMA. I know there aren't a lot of carriers that use CDMA outside the US, but maybe your carrier is one of the few. I would try updating the radio first before completely giving up on it though. If you can find out whether they are CDMA or not, that'd help decide whether you can use the Nexus 4.
Oh, and "ROOTING/MODDING WILL CAUSE PROBLEMS" is kind of misleading. Yes, technically, flashing new ROMs can affect the signals and stuff, but if you flash a ROM that has had plenty of testing, you'll be fine. Just pick a semi-popular one.

What's the version of android? If it's 4.2.2 the baseband should either be 48 or 54. 33 is an old one.
Does calling work? Or both calls as well as data don't work?
If it's just data you need to make sure data is enabled in settings and also your operators APN is present.

Nexus 7 2013 4G LTE no way to manage Data plans

Google seems to not care about rest of the world with their devices, only the USA I guess.
I got myself a Nexus 7 2013 4G LTE from the USA to use here in Egypt and I've read numerous posts about it not supporting normal GSM phone calls with a lousy reason that it is a tablet not a phone. YEAH SURE, then why Samsung, Asus (own devices) and many others offer the functionality ?!
Anyways I said ok, I will use it only for Internet Data the realized even that is a pain to do.
Here in Egypt we use pre-paid SIM cards and that requires USSD functionality which Nexus 7 4G LTE lacks so every time I need to renew or charge my Data plan, I have to take the Nexus 7 out of the case, pop out the SIM card, pop it in my iPhone, renew/recharge, pop it out of phone and back into the Nexus 7. How convenient! .
Any way to fix that ?
I don't know about Egypt, but here in Australia, just about all PrePaid services can be recharged online. Instead of taking the SIM out, why not just use the one already in your iPhone, and recharge using the iPhone's browser?

1. It's a tablet....not a phablet. It's not meant to be a phone intentionally. Other devices are... Because they intentionally make them that way.
2. It's sold as a USA device. This has nothing to do with Google not caring about anyone outside the USA. The model doesn't currently have all the support for international use. That's why it's currently only sold in the USA.
Yes it does stink. But I believe Google made it clear the limitations I would have outside the USA. Maybe an update will be released that will add some functionality that will help your situation.

Actually, all variants of the Nexus sold on the Australian Play Store as well as through various retailers. It's not a US exclusive.

I tried charging online but for some reason when the SIM is in the Nexus 7, it won't work so I have to put the SIM in my iPhone first for either online or USSD charging. I think it has something to do with some network requests that is blocked or can't function on the Nexus 7

1-As I mentioned, I am ok with it not having a phone functionality but at least they should've made it fully functional with mobile data
2-Actually I've also tried Nexus 7 LTE EU model (from the UK) and it has the exact same issue and the only difference is 4G LTE frequencies that are a little bit different but it is not a problem because we still don't have 4G LTE coverage here and H+ is fast enough for me.
Many people complain about the same thing in Google forums but no official response yet

I'm going to challenge (1).
The fact is that the chip they use for mobile data IS a full phone chip. You can use it for voice calls or data. Similarly, it can support up to 7 bands in LTE and HSPA+. So this isn't a choice not to include - it's a choice to BLOCK a feature. This is the same with SMS. Worse, the LTE bands for Canada are 4 and 7 but we don't get the EU model - which supports those - we get the US model which only supports 4. Worse, the US model only uses 6 of the 7 bands. They *could* have include 4 & 7 on the US model, but didn't. So Canada kind of got the worst of both worlds.
If Google simply didn't include a phone app and left it up to you to find one, I'd be ok with this. Like you say - it's a tablet and Goog wasn't marketing it AS a phone, so no foul. But they went further and not only removed the API in the OS to support phone service, they blocked the chip. That's going somewhat farther than 'we didn't intend for this to be used to as a phone' to 'we're not going let you use this as a phone in any way, ever.' they actually had to put in EFFORT to prevent you from using it as a phone.
Something similar happened with SMS. In 4.3, you can use SMS, it's just poorly supported. They chose not to include the Messaging app and only put in minimal SMS receiving software. Kind of stupid because a lot of PAYG services let you top up using a text message. Still, as we found out - if you get the Messaging app from the Nexus 5, bingo - you get send and receive SMS.
But in 4.4 - they actually *removed* API to make this trick not work. That's not a casual thing. It's intentional.
It's one thing not to put in a feature that's not required when it takes effort to *add* it - it's quite a different thing to *block* a feature that would be there if you did nothing.
The whole idea of the Nexus line was 'pure Android'. These are supposed to be the 'hero' models that show what you CAN do with pure Android and let developers do what they want. Yet clearly, Google is intentionally blocking certain functions that would be there otherwise.
And some of us (myself included) think that kinda sucks.
As a non-American, I'm also going to challenge (2) just a bit...
Google makes money from everyone... not just Americans. They intentionally sell their products around the world and collect data from non-Americans to use to generate revenue. Europe alone has almost 500M people - more than the US. China and India together is almost 1.5B people. Those are rather large markets.
Yet consistently, Google suffers from the same 'country blindness' that other US companies have. If you're going to sell a product outside the US, you have to be aware of, and take into consideration the differences. What makes this ironic is that OUTSIDE the US, there's a lot of standardisation. For example, all of Europe uses GSM and has 2100MHz as their primary HSPA+ frequency. This means phones work everywhere. They use DVB-T for digital TV everywhere. The US (and sadly, Canada since we get dragged along for the ride) insists on using different tech. So the biggest carrier uses the antiquated CDMA system and other carriers use the incompatible TDMA system in order to prevent customers moving between carriers. You use ATSC for digital TV which almost no one else uses.
Google Glass is US only. So is Wallet. And Voice. What makes Wallet so odd is that the US is actually way behind the curve with chip and pin and NFC based payment systems. If they actually skipped the US and focused on Europe and Canada, they'd get further faster and might even help encourage US retailers to accept the technology. What makes Voice so odd is that other US companies that don't have their heads up their.. ahems... can provide World-Wide VoIP at nearly free cost NOW. I use MagicJack on my Android tablet (you know - to make phone calls that you're not supposed to do because it's not a phone), yet while my American friends can call ME for free - I can't call them (well not using Google Voice anyway).
Are there alternative? Yep. But that doesn't justify or rationalise away Google's bizarre choices. That's like suggesting that it's ok that the main bridge in your city collapsed because there's another bridge on the west side of the city.

Nexus 6P in Shanghai

It's early but I'm possibly relocating to Shanghai and currently have an AT&T phone I'm considering picking up at 6P but not sure my options in regards to sim cards and such over seas and there's no better place to ask than XDA. Thank you in advance for helping!
Hey, in case you still need info: I read that Huawei partnered with AT&T and China Telecom on the 6P, but you might want to double-check if there were separate releases. China Mobile and China Telecom often use a China-developed variant of network standards. In my case, I got China Mobile SIMs that stranded me on only EDGE networks, on my Nexus 7 2013 (LTE) tablet and an older Motorola Defy+ (3G/HSDPA). China Telecom even told me to go to China Unicom. You'll find most foreigners using China Unicom, partly because you can use your imported mobile no problem.
That said, if you buy a 6P in the Huawei store, or directly at one of the service providers, you'll of course have no problem.
I'm editing this to put the important thing I wrote at the top as well:
go to willmyphonework.net and select all types of nexus 6P (only 2 types) and all types of networks (only three types). You will see what sort of network coverage you get - I love that site so much.
I am by no means an expert in this area.
But I am using the 6P in Beijing and I am quite happy with my choice. However, I don't find visiting Phone stores etc easy - perhaps Shanghai will have more access to English speakers than Beijing... I have heard that some of my colleagues (non-tech) are now finding success with Xiaomi, one plus, and Huawei directly putting google services on their phones. I still end up assisting most who can't afford the iphone option and need google flashed onto their android devices.
2 things I have noted.
1. I was warned about it prior to buying, but did not fully understand. You need to follow a couple of processes to remove the problematic exclamation mark/wifi issue. You will have wifi, but it will be annoying each time to manually enter new networks each time until you do this.
2. If you root and flash new ROMS - unless you have internet access that has been redirected or vpn'ed (I don't know correct terminology, sorry) at the router level, you'll get stuck at the scanning for networks stage of device setup. You can't skip the network set up either. You just stare at a 'this will take 2 minutes' for eternity.... The fix is to find a network - like starbucks or some other western type of router set up. Then it allows you to skip the network initial set up.
I don't use China unicom, but that's because when I arrived in China 6 years ago, they sucked in terms of phone coverage. They are much better now apparently, but I have my china mobile number, and I don't really feel the need to change my set up.
If you have any worries about your phone working and which network to use, go to willmyphonework.net and select all types of nexus 6P (only 2 types) and all types of networks (only three types). You will see what sort of network coverage you get - I love that site so much.
Have fun in Shanghai! and you know ... Don't get Shanghaied
You will not get China Mobile and China Unicom LTE access with the US variant of N6P because of the lack of bands. With the international variant I have, you are free to roam the country and nearly all bands are covered. Sadly, no mainland China store will sell the N6P, unless you're willing to go to the chaotic imported phone market and seek for one - it's recommended that you get it through your US importers.
And yes, like said above, you need to root and do some (easy) steps to prevent the WiFi exclamation mark from showing up, otherwise your phone will refuse to automatically connect to WiFi even if the hotspot does have internet access.
Andy, thank you again for your advice and help in regards to the wifi problem.
USF guy, as for buying from taobao (online store) or markets, it might be fraught with difficulty for non-Chinese. My suggestion is to buy from as official as you can. Buy in HK is a good option.
The reason is because you just don't know what your getting from online sellers. For example, on my last travel to Guanzhou, I stumbled accross a phone market that was six blocks wide and long and sold every imaginable mobile phone internal and external. I very much doubt it is the only market of its kind in guangzhou and China. Simply, I don't think it would be too difficult to buy and make and sell counterfeit devices - and honestly, you might find it best to just pay the extra 400 rmb that gives you peace of mind.
You're very right about that kind of market - they might not sell fake devices these days, but the source and originality (i.e. not disassembled or no replaced parts) are questionable at best.
However, buying from HK will give you a charger that's unusable in mainland unless you purchase an adaptor separately. The only genuine option is from Taiwan, where an int'l variant is sold with mainland-compatible charger. If @USFguy is willing to arrange a trip there this would be a feasible solution. If not, then the only partially reliable one is to try and find one through US importers - at least they're more reliable than Taobao.
P.S. My own Taiwan N6P is bought on Taobao. There are many trusted importers out there, and for a device this new and this unpopular in China, there's no motivation for counterfeit.
Well, not exactly. There is one band working.
Tried Project Fi (using China Unicom) and China Mobile, most times you can still get LTE outside, otherwise, Edge you know.
I was in Shanghai last Christmas and purchased a pre-paid SIM card from China Mobile, it works fine. I also tested UniCom or China Telecom using my friends' sim card, Nexus 6P works fine with all of them: 4G LTE.
