Hey guys, got a question: are you running wcdma preferred or do you use gsm only? The funny thing is that with gsm only I got all 5 bars, and with wcdma preferred it is 2/5. Could someone explain this issue and the differences between these 2 to me?

Who is your cell phone provider in your area?
i thought the inspire had teh euro 2100mhz band removed and only replaced with 850/1900? are you sure the inspire has 2100?
l tryed *#*#4636#*#* and selected euro radio band in menu but device didn't switched! actually I need 2100 band support...

Not without changing chips on the main board.
Purchased a Jiayu g2 to play with so far the phone is very nice. It is suppose to work with 850/900/1900/2100mhz wcdma however I cannot get it to work on 3g with att I only get edge and have tried just about every apn setting I can. Does anyone else in the US have this phone working on 3g? I have it rooted. Funny never thought I would say this but it is a very nice phone.

A lot of these Chinese phones state they're quadband GSM, but only have 2100 for 3G. Correct me if I am wrong.
Also, do you accidentally have GSM Only set?

here is the link for google translate.

this is the manufactures website and in the product parameters tab it shows 850/900/1900/2100 wcdma 3g and even in the engineermode menu it has them listed. i only paid 160 for it but to be honest it is a real nice phone and i was completely shocked at how well it was constructed. i even have it rooted. if there is anyone else out there that has this phone in the US or anywhere i would be interested to find out what bands you are on.
Take a look at the specshere
It shows 2100MHz for 3G
Don't be fooled by Engineering mode. It may show the options for specific MHz, but if the phone doesn't support it then the options pointless and misleading.

i hear what you are saying. but the fact that the manufacture website shows the bands. i understand that the selling sites are all diff some show 2100 some show 850/2100. but for 160 it was worth a shot.
So no one else in north America has this phone?
Hi,
I have heard that MTK6575 SoC does support 3G on 850MHz/1900MHz. Two things might prevent it from working.
1. Your cellular provider maynot be providing 3G on both 850 and 1900 where you live. It could just be on 1900MHz where you live. Could you go to some other part of the city and test it?
2. I have read that the antennae required for 850/1900MHz is different from 2100MHz. So, even if the SoC supports it, the signal strength is not strong enough to make it work.
I would be very interested in your test results since I am thinking of buying one.

Because China Unicom 3G is @ WCDMA 2100MHz.

Hi! Did you insert your 3G SIM on the SIM 1 slot? It is the only SIM slot capable of 3G (WCDMA). There are two slots in Jiayu G2 and only SIM 1 will work with 3G. SIM 2 is for GSM only.

yes i did. i have even tried to get help from Ejiayu.com and no one replies. the spec on the their website show is is 850/900/1900/2100 mhz wdma and it shows in the engineering menu as well but i think it is a lie i can not get it to work at all in 3g. My sim works fine in my Pantech Burst 4g LTE. i have not given u completely but i need someone who has an in depth knowledge of this phone to help
3g access

u might try and see what the apn setting is
u might have to input the correct apn for your carrier
I bought a Nexus 5 from the US and am using it in India on a vodafone carrier. 2g calls work fine.
3g data does not. When i turn data on, it turns to H - > 3g -> and no signal and the cycle continues. I have tried replacing the sim twice to no avail. Is this a modem problem ? Should I flash to a different one ?

Hmm. Sounds strange. You running any custom software? Have Preferred Network Type on the best selection for your network? Have the correct APNs? Those are usually the main culprits of issues like this.
My nexus kept changing between H and 3g and I couldn't figure out why. Eventually the reason behind it was my preferred network type got changed to 3g instead of LTE. So I would check that first.

So the radio is crashing?
How about doing a *#*#4636#*#* and then selecting menu (3 dots) and do radio selection and then choose EURO frequencies and see if that helps?
Looks like I might have a solution for this, which I will try later in the day. This is definitely an issue with the carrier and not with the phone itself. The carriers themselves do not support the phone, hence you would need to get your sim card activated on a known good phone and then once its activated, use it on the nexus 5. I will confirm this tonight.

The US version has different radio bands than the international version. That could be why you are having issues.
North America (D820) model:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Rest of World (D821) model:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20

That switching is intended. The phone idles on UMTS and when data is called it switches to HSPA as indicated by the icons. It's not supported in all T-Mobile markets, but it is on mine and presumably yours.

Please PM me if the issue is resolved.
I am using TMO SIM on Verizon S III on CM12.1 (5.1.1). Only I have issue is Data. Always data is on "Edge". Is there any way we can change from Edge to LTE? like changing Radio software, etc...
Please share your thoughts.

A couple of thoughts:
Did you change to the TMO settings for APN?
I have seen references to TMO using 1700/2100 AWS for data signal but is adding 1900 WCDMA in this and the AT&T SGS3 forums. My understanding is that the i535 uses the WCDMA 2100 out of the box. This may be a direction to point your searches if APN settings is not the issue.
That's correct here APN is not an issue. I am looking for solution convert from 1900 WCDMA to 1700/2100 AWS. Or is it a hardware which we cannot convert it? I don't know.

All phones are typically tied down to specific bands. More than likely changing it will not be an option

I found this
The i535 supports GSM 850/900/1800/1900 and WCDMA 2100 out of the box. We are trying to get WCDMA 1900 working (and 850/1700 if we can).

Hey guys,
So my Nexus 5 stopped working the other day, and I sent it for repairs. It's come back now and I got a new SIM. Airtel 4G here in New Delhi, India. The problem is, it will only show me a 2G connection/no signal at times. I don't know what to do. The SIM works in other phones perfectly well. I've tried going to *#*#4636#*#* and changing to WCDMA only. Doesn't work. What is the alternative solution guys?
The phone was bough in the USA but before it got repaired, 3G worked flawlessly. So at least that should work, if not 4G.
Thanks,
Crazysah
No one has had this problem? Or no one knows a solution?
Hi, Airtel as I see operate in 2G (GSM, EDGE), 3G (HSPA+) and 4G (TD-LTE band 40). But Nexus 5 (USA model) D820 doesn't support TD-LTE (band 40), so for sure you can't connect to 4G. But 2G and 3G should be ok. You can reset network settings and check again.

Yes. 3G should work at least. But it isn't and that's the problem. Before repairing it, it used to work with my mom's Vodafone 3G connection. What's the solution here?
Can you try to restart and after that change to "GSM auto (PRL)" from *#*#4636#*#* menu? Are you tested other device with this SIM in the same location ?

Tried that. With no luck. I changed it to GSM auto (PRL) and stayed on that menu. Still showing E with full signal strength.
Any idea guys?
Nobody at all has any solution to this?
i had this problem on my d821 eu version in algeria same problem as you sometimes i got 3g but no lte :/ it got boring so i sold it tried every rom on every android version official and unofficial diffrent radios and basebands it just doesnt work you should say goodbye to it sorry
