[Q] Will Nexus 7 work on 3G sim in India?

Hi...I am planning to get a Nexus 7, 32gb, wifi+mobile data, unlocked model from US with the help of a friend. I just wanted to know whether
1)it will work with 3G sim of operators like Airtel/Vodafone/BSNL in India??
2)Whether the device will have international warranty so that i can get it repaired in India if something goes wrong?
Thank you..
I have Nexus 7, will any indian SIM work on it
I wanted to know if any Indian SIM will work on Nexus 7 3g.
Does anyone have an answer ? I am also planning to buy the Nexus 7 3G model too.
Will it work with ANY MICRO SIM ? or is it specific for DATA ONLY SIM CARDS ?
It should work..
And Asus have international warranty for most of the stuff they sold.

Hello Guys,
I will receive my new Nexus7 today from US.
I have some points that I can clarify:
1). Yes it is a 3G device but does not support voice call only data is supported.
2). All Indian 3G sim cards will work (micro sims).
3). Though, sms can be used using sms apps like GOSMS Pro.
4). The device has a voice calling chip enabled but it is locked on the radio level and till now developers have not devised a way to unlock it or get it to work, you all can find lots of discussion on this on different user threads here on XDA.
not working in bsnl cellone
I own a nexus 7 in india originally shipped from us. The At&t sim works jus fine, with that my n7 detects APN and other things perfectly. But when my bsnl cellone Sim cut to the micro Sim size is inserted, it shows no service and there isn't any APN listed.
I tried the following
1. setting up APN manually. but n7 doesn't save the APN settings that I enter
2. choosing cellone network manually in the mobile networks section. but it says cannot connect to this network, try again later.
this is my experience I am trying other options but no progress so far. any suggestions?
I'm using n7 3g which was brought here in India by my cousin with tata docomo photon 3g sim cut to size. Everything rocks and blazing fast

After you enter APN settings, before going back you must click 3dot menu and click on save for it to save settings. Then go back and select that APN.
If you just go back, it wont save it.
I have 3 N7 in family for 3 members on Airtel, Vodafone and MTNL respectively. All working just fine with 3G.
Nexus 7 works fine on any 3g micro sim plus wifi.
I also received a voice call on my landline in US from India from the Nexus 7 through a google voice activated number (using grooveIP) and when the device was in the US in November of 2012 - could make voice calls to India through Vonage extensions
Just my two cents

Thank you.

Galaxy S4 i9505 suddenly shows "No Service"

Hi All
OK... for years I have been using an S4 and been really pleased with it (UK model i9505 SIM locked to EE Network).
Recently I was given a Note3, so have been using this with my EE Sim and left the S4 sitting in a drawer for a few weeks.
This week I ported my number from UK EE to UK Vodafone - so the original contract SIM which I had in my S4 is no longer available to try as it has been disconnected!
Anyway - I sold my S4 to a friend for her son for Xmas and I thought I should wipe it before giving it to her. I had Android 4.4.2 with CWM and also had CerberusApp rolled in the ROM so when a factory reset/wipe was done CerberusApp would still be there. However after doing a wipe I inserted a PAYG EE SIM and it says no service and shows a no entry sign on the top bar. When I put in a Vodafone PAYG SIM or O2 PAYG SIM it shows strength of signal (i.e. no 'no entry' sign) but says that the phone is network locked - which is correct!
But I cant work out why the EE SIM (which is the correct network) wont work. I have tried the EE PAYG SIM in my unlocked Note3 and it all works OK - so I know it cant be a SIM problem.
In desperation I upgraded the O/S to Android 5.0 using Kies and all seems OK but still the same problem. I have checked the IMEI is all OK (*#06#) and its all good - so I am lost why this wont work. Its almost as though the phone has been barred on EE - but its my phone, bought from a work colleague, so not reported lost etc so there is no reason it should be barred.
Can anyone throw in some ideas, or even let me know if there is a way to remove carrier lock on the S4 without doing it through the carrier as my colleague is not with EE now either, so I will struggle to get them to unlock it.
Additional info:
Wireless works fine
IMEI Number shows correct
No SIM/non EE SIM inserted - says not registered on network but see signal strength on top bar
EE SIM inserted (correct for carrier lock) - get a no entry sign and no signal strength on top bar
Model - GT-i9505
O/S - 5.0.1
BB - I9505XXUHOD7
Build - LRX22C.I9505XXUHOD7
Any help would be great as if I cant get it working I will need to go buy one for my friends son before Xmas as I have had and spent the money
Thanks in advance

Bump... anyone got any ideas?

Nexus 4 only work with at&t mexico, no other carrier

Hi, i recently buy an used nexus 4 in ebay, simply for nostalgia, so, i´m in Mexico, the nexus 4 that i had 3 year ago, was unlocked, so, i supose this too, when arrive, i connect to wifi immediately without any sim inside, the cellphone request for one upgrade, i accept, after that, i put my sim from Virgin Mobile and the nexus only showed " no simcard inside, only emergency calls.... y try with other carrier, weex mexico (virgin and weex work in Movistar, they are OMV) and the same all.... finally y put a sim from at&t mexico, nothing... with the sim (att) inside, i downgrade to android 4.4.4, when woke up, the nexus 4 with the same result, No simcard, so, the cellphone wasn´t detecting any simcard, after that, it request for the next upgrade, lollipop 5.0.1 that i accept, but in this chance, the nexus with the simcard from ATT showing signal¡¡¡¡¡ the cellphone was working at 100%, i made a couple calls, without problems.
But, i try with the other 2 simcards, and it doesnt detecting, simply show again No simcard, emergency only, so i switch back my Att sim and this is detecting without problems....
I install a rom named Pure Nexus, waiting for work, but the same, only with ATT simcard work, so i downgrade again to 4.4.4 but in this chance with other simcard differnt from AT&T, Virgin mobile.... but nothing, nexus 4 is not detecting any other simcard than at&t¡¡¡¡¡¡
What can i try? could be a nexus 4 locked only for one carrier or what? in google dont appear in blacklist, the imei is good nor corrupted... could be the sim holding?
try going back to stock using the nexus 4 toolkit,then root, and try one of the hybrid models LTE enabler or download the 107-3, if that doesnt work also, then it might be defective.

use this to go back to stock
http://www.wugfresh.com/nrt/
you will get android 5.1.1, you can also install custom recovery and root using it.
then if the sims doesnt work, change the modem using the LTE Enabler you can get it from the Play Store.
it has the modem until version 104-33, but im using another one the 107-33 that i got from
https://drive.google.com/open?id=0B77BTW0zStYCZmpPR0xTaWE5OUU
104 33 and 107 33 are hybrid modems, but you can also install stock modems,
the modem is the one that allows you to make calls and use the data channel in your phone
hope that makes sense, let me know how it goes. regards.

well, i flash EnableNexus4LTE.zip and LTEhybrid33-84 without good news, i have the same issue, only at&t mexico sim is detected and the others no, well, i´m now with 4G LTE but only working in at&t
i don´t know what other things trying in the nexus, seem like only prefer at&t sim and no one else.
Adding information, i have sims from cricket USA and t-mobile USA, i know is not supported in México, but it will be for try to get something like: Sim not activated... or invalid sim, but other different from my nightmare: NO sim, please insert....
SOLVE:
I´ll auto answer... after a lot off attempts, i found the problem is the sim reader, like i posted before, only working with at&t Mexico sim, so, I watch the thickness of this was little bit smaller than others, my "strategy" was try to imitate the fact that at&t sim is making contact gently on pins, i take a 3in1 simcard, and i put the nano sim in micro sim adapter (included in the sim) but not in all (i don know exactly the words in english), so by this waya the nano sim standing on a little bit from microsim adapter.
when i insert the sim by this way an my nexus, and turn on, the cellphone recognize inmediatly the sim, so i found the key of this problem, like i said, the problem here is the sim reader, because, a normal and good sim reader not need this tricks to get signal.......

I glad its working now, you can stay on 5.1.1 with the hybrid modem if you got the 4G signal, or return to 4.4.4 if you want. regards.

you should be able to select "LTE/GSM Auto" that way the phone will switch to GSM when needed.
and the option is only visible under *#*#4636#*#* menu, also, we have to switch to LTE/GSM auto, if the phone is restarted. there is a way to make it persistent, but I haven't tried. i'm fine with it since i don't restart the phone too often.
hope this helps, regards.

Unable to register phone on T-Mobile network

I've been a T-Mobile customer with my OnePlus 1, got the OnePlus 5 today and went by the local T-Mobile store and got a new SIM card. A couple hours later I got around to actually setting up my phone. I realized I wasn't getting app verification codes, so I called T-Mobile to make sure the SIM card activated properly. She had me confirm the SIM card was inserted properly, then she had me turn the phone off and she "sent it a signal." That got text and data working, but still no go on the phone. She transferred me to the next tier up tech support. On the phone with them, we turned off WiFi, WiFi calling preferred, VoLTE, and automatic selection for Network operators. The phone did it's search and we selected T-Mobile 4G for the Network operator. The phone says it registered on the network, but T-Mobile says it didn't. We tried the second SIM slot but no change. We did a couple reboots and still a no go. I was then told that since it's not a T-Mobile branded phone, they can't guarantee that it will work. They recommend I put the SIM in a T-Mobile phone to confirm that the SIM works - I'll do that when I get home and try it in my wife's phone.
When I turn on VoLTE, I get text and can make calls, otherwise if I make a call, it just calls T-Mobile.
Under Settings > About phone > Status > SIM status, Cellular network state shows disconnected.
I also see under Settings > SIM & network > SIM 1 > SIM name it shows the name as T-Mobile but Carrier says Unknown
Fresh out of the box, running 4.5.3. Has anyone else had any problems getting their OnePlus 5 to register on T-Mobile? I searched the T-Mobile support site but didn't find anything helpful.
I'll try the SIM card in the wife's T-Mobile S7 when I get home, but if anyone has any pointers, I'd appreciate the help.
OnePlus 5 on T-Mobile here and no issues at all.

Same here. I also have 0 issues
Are you using the latest 4.5.4 update for OP5? They had fixes for VoLTE not connecting. Even though I think that was Europe only thing, the download made its way to my phone automatically. If you're not on 4.5.4, go upgrade (it's a simple thing to do)
What are your APNs set to?
Goto...
Settings
Sim and network
Sim x (1 or 2, wherever the sim is installed)
Access point names
Without doing anything besides entering my sim card into the phone and starting it, I have 4 options
If you have anything outside of your current provider, add them. The easiest way to do this is to open up another TMobile phone you have, goto to the same location on that phone and copy settings manually to your OP5.
I did this for my wife's S7 coming from Verizon. Although she doesn't get WiFi calling without flashing firmware (which I'll be doing when she's ready) you shouldn't have that issue.
Bad SIM card
Turns out the SIM card was bad. Went to the T-Mobile store, let the guy double check everything, then he grabbed a new SIM card, popped it in and two minutes later everything was working. I asked him how often he sees bad SIM cards, he said one or two a year.
