The basebands for 3g are different in india. The i9020t comes with the 9020 baseband i think if you flash the 9023 baseband with the KD1 radio, Your 3g will work. I got my i9020t nexus from the US and am using it in india. I had a motherboard problem and got my motherboard replaced from samsung here. So they changed my baseband , Hence my 3g is working now.
I used my 9020 with vodaphone and got 3g in new Delhi. I was on vacation

I use the i9020T and I have no problems whatsoever with my 3G signal. Get speeds close to 4Mbps. I´m on BSNL Andhra Pradesh.
Which service provider? Maybe your service provider does not provide 3G in your area?
Or try this -- Go to Dialer and type *#*#4636#*#*
After that tap on Phone Information. In Set Preferred Network select WCDMA only. That´ll give you only 3G signal if available. If you want to go back to 2G select GSM only. If you want both select WCDMA Preferred but this is a huge battery drain.
Hi please give me little more insight to what you have done. Where are you from india. I am in bangalore can you pkease provide me some contact numbers of customer care. Can I directly flash 9023 rom into my mobile? Or will there be any hardware incompatibilities? Please help me I am dying to activate 3g

Do NOT flash the 9023 ROM. That could make many things go wrong. If you're APN settings are configured then do what I said above and you'll have 3G.
Hi anirudh thank you very much for your reply I have already done that but it is of no help. Please educate me littme moe in this regard

Maybe you send some sort of msg to get 3g activated. For airtel you've to send "activate 3g" to 121. Maybe Vodafone has something of the sort too.
Hi anirudh in my mobile I have already done that so mobile connection is 3g active. Can yiu please give me your number

Frequent disconnection on Vodafone
Anyone facing frequent 3G disconnection on Vodafone network? I have 9020T and have KD1, what radio are you using?
That's the T-Mobile version. The Nexus S is not a quintaband phone. Tmobile 's 3G is 1700mhz band. So I do not believe you will be getting 3G with that phone in India.

I was getting 3G connection with Airtel/Tata Docomo all this while. Now i moved to Vodafone and suddenly it stopped. Moreover, i am getting 3G connections and can access data as well, but it automatically disconnects after a while like 20-30 mins.
This is working now after changing the sim from the same operator. In case someone is facing the same problem, talk to ur operator and get ur sim replaced.

Dear all,
I was happily using Quarx CM10 build 20121118 with 3G/UMTS in Australia.
Moved to Indian now for a year to do charity work and got a local CallOne SIM.
2G/GSM works fine and 2G data is also fine.
When I use UMTS the data always drops and voice calls end after 20-30 seconds.
Could someone please let me know if this is a baseband issue or just the usual Indian 3G/UMTS implementation.
By the way, I tried this outdoors with full bars.
Thanks in advance,
Matthias
It's a baseband issue. Use the baseband switcher and select the Indian baseband with 331 in the end of the name

Oops, after changing the settings as above I now have 3G voice connections without problems, but can't connect to 2G any more.
When I select "GSM only" in network preferences or "Use only 2G networks" I can't get any connection.
Any ideas??
p.s.: In "About phone" it shows Baseband version: EPU93_U_00.60.03
Try a lower baseband
Version's absolutely fine in about phone
You can try to set 2G from the secret dialer menu(dial *#*#4636#*#*)
BTW, why do you need 2G?

Wow the menu is great! What would be a "lower" band? (sorry, I'm new to the mobile phone interiors)
Here in India it's mostly 2G when you go out of the city.
Sent from my MB526 using xda app-developers app
Lower baseband means a numerically lower one(it's 2.59 something in the beginning instead of 3.4.3)
And how did the secret menu approach pan out? Try setting it to gsm only.

When I set it to GSM only I have the same issue as when I set it to GSM only in the phone settings, it get's no connection.
I googled a bit more today and it seems there are quite some more people experiencing the same issue with the Asia baseband.
I've set it now to Central Europe and it seems to be working.
Do you know how I extract the baseband from a stock android phone? Some of the local guys have a local bought android and I want to extract the data so it can go into the next build.
Thanks,
Matthias
It's in system/etc/motorola/bp_nvm_default
Use a root file explorer app to copy and paste, however I'm not very optimistic about its chances
So, is central Europe baseband working completely?

AFAIK it is working. Voice calls now work without problems in 3g only and 2g only modes. Data modes are still very unreliable, I was hoping to get some feedback from Indian users of the forum, but besides you no one commented. :'(
For me, 3.4.3 331 data works in 3g and 2g. Voice is fine with both

ATt&T signal is very very weak, -109db.
The same sim card has 4 bars on my windows HD2 phone. I could barely make an phone call and the phone switches to emergency mode from time to time.
any suggestion? anybody has similar experience?
Not here.
Are you in a 3G only area ?
And make sure to be on Global or GSM mode.
how do i check?thanks

It should allow you to select the network from CDMA to Global to GSM to UTMS or similar under settings.
Or get into the hidden menus:
http://forum.xda-developers.com/showthread.php?t=2049805
Also make sure u have the correct Radio.
Telstra XT905 seems to work the best in the Verizon XT907
Though only Edge/2G for Data at the moment
tried All of them . no help.
one interest thing:
… hd2 shows edge network at home with 4 bars. flashed razr only gets vey weak signal.
… flashed razr can receive 5 bars at many shopping plaza.
my operator is att.
Sent from my XT907 using Tapatalk 2
Wait i think u flashing the wrong Radio.
U have a RAZR HD not the M ? if so you need to go to the Razr or Razr HD section they use a different radio than the Aussie M ones.
I had two phones: windows htc hd2 and razr m. in last thread, i was comparing signal strength between them.
I am sure this is the right forum fir my razr m's issue.
Sent from my XT907 using Tapatalk 2
oh that HD2 confused me.
Did you try a factory reset and then flashing the radio ?
yes. I flashed the original verizon rom, then fastboot to flash aussie radio. I also tried your approach to replace radio file in xml and flashed the whole rom.
will try T~mobile sim card in the next few days. at home.

These issues apply to T-Mobile users installing the current build of 4.4 (and possibly other GSM carriers but I don't have an ATT SIM to test). Motorola is aware of the issue. I read these forums pretty thoroughly and I've been answering these questions all over so I figured I'd just put them all one place. Issues as follows:
- Devices with the LTE radio active cannot send SMS
- Devices with the LTE radio active cannot send MMS (Carrier/Settings dependent)
- Devices with the LTE radio active cannot make phone calls and instantly disconnects on call attempt.
Urban Legends:
- Stock tethering does not work - I have personally tested on TMO and know it does work. Yer doin' it wrong.
Fixes
Easiest fix for now if you're on a device running 4.4 and want to... you know... be able to use your phone... is to use phone information and switch the radio mode over to GSM Only (not the auto one). This fix is a little finicky because if the phone realizes it's not running in the mode selected on your mobile networks screen it will override and turn LTE back on if you haven't selected UMTS only.
Full steps are:
Mobile network settings - Change network mode to LTE/GSM/UMTS
Mobile network settings - Select network UMTS Only
Install app linked below
Open Phone Info and select GSM Only
Phone info apk for sideload - http://www.mediafire.com/download/284l17ry2ok1yuk/Phone_info_1.3.apk
I'll update this thread as I discover more issues or as people post issues that can be replicated below.
Thank you. Finally I got the LTE turn off.
I gotta switch the mobile mode to LTE/UMTS/ gsm and select network as UMTS only. Then use phone info choose gsm only.

It was selecting GSM Only in Phone Info. Switched it to GSM auto (PRL) and I got HSPA+ back.
but Seriously dude. thanks for this info. I was tired of using my Moto G while my MAXX was just collecting Dust.
Edited the OP for a more clear fix. Thank you to vuphongkkk for pointing out the UMTS only.
I'm on T-Mobile and live in an HSPA+ refarmed area (NYC), but there are places I go on a regular basis that aren't refarmed. I set it on "WCDMA preferred" and voila, I have both 2 & 3G connectivity, with preference given to 3G.
I can't post links, but this XDA thread explains it in more detail I think: ... showthread.php?t=688492
Vodafone confirmed for anyone wondering.
H+ for UMTS only,
Edge for global.
No Sim adjusting at all
Just popped a sim in today. Getting LTE but really hating the call fail bug. Gotta place the call twice repeatedly to get it through
Maxx'd out Kit Kat
Update: Having major glitches when running LTE, pretty deal breaking for a full switch to tmo right now. Eagerly awaiting the new OTA to see if it fixes it. Seems to have major issues on the HSPA/LTE handoff. How did it function prior to 4.4?
Maxx'd out Kit Kat
On 4.2.2 was working fine, the phone just switch from LTE to 3g itself when you need to make phone call. But I had problem on 4.2.2 that if I connect to WiFi then it'll take awhile to get the LTE back. Normally an hour after out of WiFi range

Maybe thats the problem I was having? I just ended up with a 4.2.2 phone after my 4.4 got destroyed. LTE wouldnt work for me but I was in the house after switching off wifi...hmmm
Arcanexvi what's the best APN to use for 4.2.2? And do I have to have phone info installed or can I uninstall it? Since I changed all the settings to get hspa+ I forgot what the default settings were. =\ whoops and thanks for all your help so far

You can uninstall it if you want. It's extremely small though so no reason to do so unless you just don't want to see the icon. Uninstalling will NOT reset your settings.

Thanks! I messed myself all up though.
In android mobile network settings should I have network mode as global, LTE/CDMA or LTE/gsm/umts?
If its LTE/gsm/umts do I still use gsm only under select network?
And if I leave phone info installed do I have to change anything on there for LTE to work? Phone info seems to change the network selection in the app on its own so I just stopped messing with it. Thanks and sorry to be a pain

If you on 4.4 you don't have to change anything to have LTE work on your phone. Follow step by step from the beginning of the thread to turn off LTE

I'm on 4.2.2 and already changed settings. So was curious on what the original settings on 4.2.2 are to get LTE working with APN settings
Sent from my XT1080 using xda app-developers app
4.2.2 rarely get LTE data. Choose network mode as LTE/gsm/UMTS . select network as automatic. Don't use the phone info. If you already use the phone info app in this thread then use it again to switch back to LTE/gsm.. Or the option that has evething.
Remember to add APN fast.t-mobile.com
But as I mentioned, 4.2.2 has some problem with the radio , so it rarely pick up LTE

Just to add another data point, I have a Droid Mini on stock 4.2.2. I'm connecting to t-mobile with the listed apn info, global and auto. I have LTE the vast majority of the time.
