I recently bought an unlocked Google Nexus S from amazon. The Device works fine on ATT network. When I got it to India and tried inserting an Airtel SIM in it. The phone shows complete Signal strength but says emergency calls only. On the lock screen it says insert SIM.
When I search for available mobile networks it shows my network but unable to connect to it. It does not even ask for unlock code when I insert a SIM from another carrier.
Is this because the phone is locked or is there some other problem?

What network frequencies does Airtel use? If non of them match that could be why, oh and Nexus phones are never network locked
Sent from my ice cream powered Nexus S
Yeah, frequencies should be the reason here.
But only for 3g, the us always being special, especially at&t. ^^ 2g should work worldwide. Set it to "2g only" and see... (if it works, slow data, but at least you can make calls)
I got a Samsung captivate from ATT and it worked also my Galaxy S 4G. All these are quad. band phones so, they work worldwide. Could be some other problem. Got a good deal, so dont want to return it, but I guess I have no option now.
Tried a new sim?
im gonna be going to india in a month or so and i wanted to know if the i9020a will atleast work with voice in india. airtell or vodafone it doesnt matter. I don't need 3g but i was hoping voice would work so i could just use this phone in india.
did you try to reset the phone?
After several long calls with Verizon and help from Motorola insiders, I have been given to understand that:
1. Droid Maxx if not activated on Verizon, before leaving US, cannot be used on other carriers (say in Europe or Asia).
The reason is the SIM unlock cannot be done by the customer support since they won't see the device in their network if it is not activated first.
2. The activation cannot happen outside US, since Verizon does not have a network.
So bottom line is get the device activated before you import it from US.
Now, my Droid Maxx is locked to Verizon. I know the boot loader can be unlocked. Will this help me in flashing something that can get rid of the SIM lock that Verizon has in place.
My device is an employee edition so perhaps there was some extra protection added there by Verizon.
Please help.
I do not have a Maxx, but I'm replying because you PM'd me asking to take a look at this thread..
It has been my experience that Verizon's 4GLte phones are sim unlocked (on the GSM side) out of the box. I thought that was a condition of VZW's 700Mhz spectrum auction win? One potential issue is does the phone support the needed bands out of the box (think Bionic where a hack was needed to enable bands needed for T-mobile).
That being said, if your Maxx is truly SIM LOCKED, then unlocking the bootloader wont help you SIM unlock, nor will flashing a 3rd party Rom after unlocking the bootloader.
where are you located, and who is your carrier? Do they use CDMA for voice, or GSM? What happens when you put a non-VZW sim in the phone?

Thanks Mark.
The phone Droid Maxx does support these bands since there are others who are using the same phone on GSM networks in the country.
The networks in India are:
2G capabilities GSM 900, GSM 1800
3G capabilities UMTS 2100
4G capabilities LTE 2300 (this one won't work with the phone, plus my carrier does not have it either)
The CDMA is CDMA 2000 - but I have not been able to try with a CDMA SIM, but that one has a higher probability of working.
When I put a non-VZ SIM, and set to Global mode, it does not detect any signal and the search network does pretty much nothing. The automatic mode tries to connect but then throws an error saying "can't connect to this network at this time"
I am using a brand new nano SIM card (which now is back in my Moto Defy with an adapter.)
Earlier I had a normal SIM converted to a nano SIM and that one did not work, but after I put in APN manually, I was able to access data.
I tried another user's cut-nano SIM and that one worked for data out of the box (another GSM provider).
Ditto for me, but I am using DroidMini... I also have DroidMAXX which is working great (even unlocked its BL and rooted it)...
I am also from India... Using it in GSM networks... I may get one Nano CDMA SIM to test later and will report here for sure...
Thanks...

Well, we have interacted on Rimweb recently.
The radio on the Droid series is the same. The difference between the mini and the maxx in your case is that the mini has never been activated on VZ network and hence it is SIM locked. Whereas, the Maxx would have been purchased as a used item (perhaps just activated and then sold off?). So that takes care of the SIM unlock part.
Yesterday I spend around 60 minutes with global support, VZ.
I escalated the issue to the supervisor.
He checked and said that the IMEI is clean and not in any sort of negative list. So there is nothing else that they can do.
He also said, the phones are unlocked by default for global use.
Obviously they don't want to dig deeper into why three phones are not working on GSM in India.
I am now running out of avenues. Does anyone have some debugging tool which can log what is happening when the phone tries to log on to the network?

The current Droid Maxx that Verizon sells supports the following..
LTE Band 13/4 700/1700
EDGE/GSM: 850/900/1800/1900,
HSPA/UMTS: 850/900/1900/2100 (download speeds to 42.2 Mbps, upload speeds to 5.76 Mbps
From what you listed, the Maxx should get GSM/Edge/HSPA/UMTS coverage there. And of course, no LTE.
The CDMA side of the Verizon phones is still "locked" so I also would not expect CDMA to work. In other words, if your carrier NEEDS CDMA, stop trying.

I've been through this with some trying the Moto X in India, and I've been through it while trying my T-Mobile and ATT sim's in my Verizon Moto X.
From what you are describing, it sounds like your APN settings for your carrier on the phone are not set right.
Example... When I put my T-Mobile SIM into my Verizon Samsung Galaxy S4, I get "unknown sim" and bars, but no network connectivity. Nothing works. By going into the mobile network settings on the phone and adding an APN with the T-Mobile settings, features like calling, SMS, data, etc. start working. I have had occasions where I thought I had the APN right, as calls and data worked, but MMS only partially worked (would send but not receive). When I do have the settings right, everything works. Similar thing happens on my Moto X with T-Mobile SIM.

Unless you have an active account with Verizon, and are trying to use their service when traveling, Verizon wont help you. In other words, unless you are trying to get your Verizon phone, working on Verizon's Global Roaming service, on your currently active Verizon account, they wont help you.
Even if you are a Verizon customer who is just traveling and popped out your VZW SIM in favor of using a local prepay sim to save data/voice costs, once you pop that VZW SIM out, they wont assist.
But you have received confirmation of what I said.. the GSM side is unlocked.
The SIM you are trying to use is from a GSM India carrier? As long as they only use GSM (no CDMA required), your only hope will be working with them. Telling them your phone is SIM Unlocked and going from there. Or finding a local message board for the carrier, and hope people are discussing use of "3rd party" phones, and you might get some help there.
I really think it will come down to the APN settings for the GSM carrier not being correct on the Maxx.
I can't offer any more than that. Sorry.

I have now put in a CDMA SIM card, but run into another problem with that. I will activate that SIM on another phone and then pop it in the Maxx again and check. But CDMA should work fine as reported by other users.
But the problem is the GSM part, because that is what we need to get working.

That is bad on the part of Verizon. I have purchased a Verizon device off-contract and that device is a global one. So I am entitled to some support from them even if I am without a service plan.

Yes. Local carrier. And for now, there are three such XDA members who have been facing the same issue. In one case, a member was able to make calls and receive calls and also use data. Then after a few minutes, the SIM invalid message popped up.

APN settings are pretty easy. I did that with my earlier SIM and I got data working. There was no voice, so I gave that SIM back to the carrier and got a brand new nano SIM. Now, nothing works. The old and new SIM are for the same number and same service provider.

Right, you got just DATA working with the APN settings, but the correct APN settings are also needed for SMS, MMS, Phone calls, etc.
I've had an issue where I had voice but no data, and it was related to APN. I've had an issue where I had voice, SMS, data but no MMS, again, it was related to APN settings for the carrier you are using.
So good luck!
the problem we sorted out to get gsm working in india first the phone must be activated on usa to get it work on india so can anyone help us > @s_u_n
So, after using the phone for a week on GSM with all application updates installed, I can safely state that
1. Verizon activation is not needed for non-VZ networks to work (at least outside US).
2. A full FXZ was installed and it probably solved the modem configuration mess that the phone might have been. Perhaps it unlocked something?
3. Four corner activation bypass method was used (as described in earlier Motorola phones).
Either 2 or 3 solved the problem
There was nothing to do with APN. Data works even without any APN settings out here, just like on my Motorola Defy.
I was on a trip recently and I turned off LTE through quick tile because the place I was staying at did not have LTE. Now, I seem to be stuck on HSPA.
I reset network settings and even did a complete wipe of everything and I am still stuck on 3G. I have Preferred network type set to LTE (recommended). I am using the ATT LTE access point (screenshot attached).
Any ideas? Any way to check if it's hardware of software? I am running 44S.
I used to have LTE here and my gf's iPhone 6 has LTE in the same location.

I'd think the only reason it'd be hardware is if something went belly up. Seems doubtful to me as bard hardware is fairly rare. More likely software. A few times I've lost LTE after changing out my sim card, and only the phone company doing some type of reset has 'fixed' it. Not often, but enough to be a PITA.

Add "hipri" under APN Type, save, reboot & see if that helps. :fingers-crossed:

I tried that. I also put my sim in other OPO and it got LTE. I get LTE with my sim card on OPO thats usually on t-mobile (but his sim did not get LTE on my phone). I also tried my SIM in a nexus 5 and that got LTE as well.
Im fairly sure its hardware failure

A metric boatload of questions....
How's the audio processor?
How does NFC work?
What are uses for the fingerprint sensor besides unlocking the device?
How's the video quality?
Does it overheat or start to get warm during tasks?
What's your best SOT?
How easy is it to switch networks with two sims?
I have more questions but I'll relax and ask them later.

How's the audio processor?
For recording videos it is very clear and loud. Haven't tested it with a hifi earbud yet. Sound from speakers are decently loud but do now sound as bassy as the HTC one or nexus 6 speakers. One thing that's great is there is NO stutter when listening to audio with the front facing speakers and changing from landscape to portrait (as happens on the nexus 6)!
How does NFC work?
NFC is the same, tap on something and bam, nfc'd.
What are uses for the fingerprint sensor besides unlocking the device?
So far under android 5.1.1. Just to unlock the device. Once marshmallow comes out I'm sure more uses for it will follow.
How's the video quality?
Video quality is amazing. Colours have a nice balance to them. I turn off the x-reality engine.
Does it overheat or start to get warm during tasks?
Warm when charging and doing some serious downloading or installing a **** ton of stuff. Not hot at all. Haven't recorded 4k video. Will wait for the new camera app to be pushed out before I make any judgments.
What's your best SOT?
So far after one day of use 3.5houra SOT at 75% brightness constantly.
How easy is it to switch networks with two sims?
Seems fast enough. Just pick which for LTE and which for gsm voice. One thing of note... you cannot use LTE simultaneously on the z5 Dual. You can have one as LTE and one as gsm (2g) for voice and text only (so basically Rogers). Calling when one on sim and if someone calls you on the other sim, it will forward to your voicemail.

When you say "just pick which for LTE and which for voice", do you mean you can actively pick which SIM is using LTE Data via the settings app, or do you have to physically switch out the SIM cards in the actual device itself? I currently have a Dual SIM Phone but to pick which one gets Data, I have to physically remove and switch the SIM cards, not through the system's settings.
You can switch them actively on the go via the settings. Sucks you can't use LTE for both sims at the same time though, but I guess that would be a huge battery drain
got the single sim - E6653 on Rogers in Vancouver, so fast!!!
I have a follow up question on the dual sim support. So you mentioned one SIM supports LTE and one will support GSM/2G.
So is the second SIM is only 2G or can you get 3G/HSPA support?
Also what happens if you get a call on the LTE SIM? Will the phone CSFB to 3G on the LTE SIM's network to accept the call (since no VoLTE support)?
Hope that makes sense.
I was considering the dual sim model since I have two SIM's myself. One for work and one for personal. Both are voice and data LTE but on separate networks (AT&T and TMobile). If i'm hearing you right then there isn't much advantage for dual sim in N. America since 2G voice isn't any cheaper than the 3G or LTE...in fact the 2G networks kinda suck now since all the focus is on LTE and getting to VoLTE.

As far as I am aware, it supports gsm network (most likely 2G only). I don't have data on my 2ND sim so I'm not sure if it supports 3G data, I doubt it though.
If I receive a call on the LTE sim, it reverts to hspda yes. No VoLTE on telus AFAIK.

Does the Sony or Android UI tell you which network you are connected to on the primary line? In screen shots it seems like it just shows signal strength on both lines. I'm curious if it says LTE, 4G, H+ or H. My ATT service switches quite a bit here in Houston so sometimes I force the phones to 3G only in areas where reception is awful.

My Xperia Z5 Dual will got the following message and forced to restart when I have changed "Preferred network type" in settings--->More--->Mobile networks--->SIM1/SIM2, or even I have replaced another SIM card. (I have turned my phone off when replacing SIM card.)
Your device will now restart to be optimised for your service provider.
This is very annoying and anyone knows how to fix this issue?

I stand corrected, its 2G standby! That being said you can switch the primary data line to SIM2 to LTE/HSPA which forces SIM1 to 2G :crying::crying::crying:

I'm on 5.1.9 but despite i activated the option only the Sim used for data traffic can actually connect to 4G. The other Sim seems forced and stuck in 3G at 900MHz (band 8)
There's no use for LTE on the phone sim unless you are lucky to live in China, India or Finland AND use a sim card of the view carriers supporting VoLTE in the OP6.
No sense reply. OP declares dual 4G on both Sim. My phone supports 4g only one sim and the worse the secondary sim is locked on 3G band 8
Are you using any custom rom? i faced similar issue on havoc rom

No. Pure stock 5.1.9
I had the same problem. But i went back to 5.1.8 and problem solved now dual 4g active.
Crazy but settings the phone on the English instead of my local language the problem seems gone.
I'm in America and I'm having the same problems after the 5.1.9 update, one SIM is always in regular GSM mode even with the dual-4G mode enabled.

That is completely false. Even T-Mobile in the US supports VoLTE. Even if it didn't though, it still allows for faster SIM switching since it was already on LTE.
Curious how you guys are checking it. Mine both say VoLTE and it seems to be fine for me.
I reset the network settings and it work for a few hours. The dual sim 4g instructions are broken .
