jiayu g2

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

Will the T-Mobile version work on Videotron?

Hey, small question here. I'm going to buy a used Nexus S from someone in the U.S, using T-Mobile. I currently have the Motorola XT720, and I have Videotron as a carrier. (Quebec, Canada). I just want to know if I buy the T-Mobile version, will I be able to use my SIM card (that is currently in my XT720) then have 3G connection with data?

Vidéotron uses the 1700MHz frequency UMTS, same as T-Mo, so it should work fine. Make sure you get a i9020T and not i9020A.

Just wondering, I'll get 3G with Data?

Motorola Xyboard 10.1

can you unlock it and use it on AT&T LTE? I am guessing not but I haven't seen much about this tablet so figured I would ask.

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.
**THIS IS A SERIOUS PHONE MOD. NO ONE BUT YOU IS RESPONSIBLE IF YOU USE THE FOLLOWING**
Quick search came up with the following thread (says TMo) which someone acknowledges two posts below OP that it works on ATT:

thats what I as wondering to. Be able to unlock it so it works on GSM when not in a 4g lte area assuming it has the ability to use AT&T LTE network as well

The hack I posted allows you to use ATT hspa+ (which is supposedly 3.5G) ha

haha I may have to try it I am curious now lol

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.

Can you please tell us why you think it's blocked?

HELP!!!!!!!
I have the 10.1, and like allot of folks have an issue with the USB/HDMI circuit board and I am no longer able to charge my device, so surgery was performed, I have my device dissembled but I am have had no luck finding the board, calling Motorola was worthless, "OH yes our tech have it if you'll send in your device...." Ya 150$$ for a 20$$ part NOPE. I did find one company that listed the part number 84014710001_B but they no longer carry the part???? How difficult can it be to find this part? does anyone have one I can buy????? HELP ME PLEASE!!!!!!!

I believe it was posted on XDA sometime ago.... but seems like you were able to get it to work with your hack.

can not get 4g(at&t) on verizon galaxy s3!!!

ok, i got some problem with the verizon galaxy s3. I use at&t simcard on this phone and it seems working just fine. Here's a thing, after set apn setting on the phone i just only get edge speed(2g), i need someone helps me to figure out how to get the 3g/4g speed on this phone or give me a right apn setting for this. i really appreciated. thanks very much!

The bands for AT&T 3G/4G are locked on the handset, you are going to have stick on edge sadly!!

It's not a worst thing though. I got this one for only 100$ off craiglist and it works just fine. It just does not work right with a data, remind me of few years back when 2g was a fastest data service lol. Thanks again for let me know this issue.

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.

Hi Hyelton, thank you for your reply. The phone does too, its listed on the specifications and it picks up the band and the network when I do a manual search for available networks. when trying to connect it connects to the HSPA+ network not LTE. I believe this is a limitation that ATT might have added. I need someone help me remove it.

AT&T would NOT have a limitation on it. If you do a network search and it comes up, and fails to connect something somewhere else is wrong. Make sure you have the correct APN?

The APN settings have been checked and work fine on a note 3 N9005, somethings up with the d850, can someone help with that please

the phone does, the speck says, roaming 1800 on the att site and even the lg specs say it does. the but i think the stock rom on the att d850 some how prevents it, please help
