It is been a long time coming and visit this topic, At the begaining,many says that the CPU is allowed to make the phone call, and not, It's been few months, but not any latest info posted. could there is anybody tell me how possible for it using as a phone... waiting for the professional to tell.

Me too. Just when I got addicted to google experience and had selected my next device to be Nexus 7, I was told that it cannot make 3g calls and now i am sad... I am praying that the devs at xda can find a way around for guys like us.

I wish if i could help in enabling the phone app. I have 9 years of programming experience in c++ and C#. I think if i get the source code of jelly bean (for N7), tools to compile the source code, some knowledge to put the compiled content on device, then i might be able to help here. let me know if any one knows about a useful tutorial walking through all these steps.

Okay time to unsubscribe from this thread. Too many clueless hopefuls, not enough actual devs. Folks, all the obvious strategies have been tried.
Bye...

I maybe have been living under rock
but what is the reason behind to crippled GSM calling on nexus 7 3G?

even a broader question
why cripple the device at all??
no tethering?
no camera?
no sms?
no gsm calling?


why why why why why why and why
I realize camera, sms and tethering has been fixed with a work around (anything not from google I call a work around :p)

what is the business reason for this?
do people even care? if yes then why google not respond with the reason why?

Tethering and SMS work just fine if you have the right sim card. For other things Google don't want you to have it for the price. No HDMI out as well BTW. You get some more features if you fork out more money for other tablets. Some Samsung tablets have calling ability, I don't buy them because I prefer Nexus.

This is so unfair, u get a 3g version with a cellular modem still u can't make phone calls
I thought devs will surely cracking open the gsm capability and bought it all the way from USA to use it as a phone replacement but it has turned out to be a complete fiasco :(

ussd

what is this ussd code ??? i dont get it

protocol used by GSM cellular telephones to communicate with the service provider's computers. USSD can be used for WAP browsing, prepaid callback service, mobile-money services, location-based content services, menu-based information services, and as part of configuring the phone on the network. E.g, simply dial *126# to check balance on Digi aka fat yellow man

    BEFORE YOU POST HERE - Keep in mind this is now a DEV thread and only those with a glimpse of DEV knowledge should be posting.
    There is other thread with the same subject open to everybody discuss it.

    Please, this thread isn't related to VOIP, SIP calls or Tethering and
    It's only to 3G version of Nexus 7.


    What do you think is the possibility of us getting this function guys, even if its not officially supported.

    I've seen it built in on the 7" samsung galaxy tab 2.

    http://www.youtube.com/watch?v=wZ9RN...t=HL1351349133

    At the moment we know:

    1- The chipset Intel (Infineon) XMM6260 is built-in on Nexus 7 3G (the same chipset is in that rather long list of phones). It means no hardware limitations.

    http://forum.xda-developers.com/showthread.php?p=34386544&highlight=6260#post34386544
    http://pdadb.net/index.php?m=specs&i...exus_7_3g_32gb
    http://forum.xda-developers.com/show....php?t=1483053

    it also the same controller is in the following devices

    - Lava XOLO X900 [Phone]
    - Lenovo K800 [Tablet/Pad]
    - LG-P920 (LG ?) [Phone]
    - LG-P925 (LG Optimus 3D?) [Phone]

    - Huawei E369 (3G Hi-Universe) [USB 3G Modem]
    - Huawei MU733/MU739 [PC/CE Module]
    - Samsung Galaxy Nexus (I9200) [Phone]

    2- SMS texting works perfectely with the native mms.apk but MMS messages crash the app (missed mms APN + framework parameters?)
    http://forum.xda-developers.com/showthread.php?t=1998702&page=4

    3- Modified framework-res.apk (by modifying bools.xml entry to name="config_voice_capable">true) shows up the native dialer (phone.apk) on the UI
    JB 4.2 http://forum.xda-developers.com/showthread.php?t=1958686&page=12
    JB 4.2.1 http://forum.xda-developers.com/showpost.php?p=34736932&postcount=314

    4- When placing calls trough the native dialer (phone.apk) with Skype app installed, it shows up a white menu asking "Do you want to complete this action using..." the options are "Mobile data" (w/ phone.apk blue icon) or "Skype" (w/ skype icon) and "Always" or "Just Once" (perhaps there is missing a "Phone" profile (or APN) as an option too)

    5- If Skype is chosen, the call is complete and everything goes well, but if "Mobile data" is chosen, we get a single sound (bip) and the call is not complete.

    6- Changing the DPI to 320 in build.prop file allow us to add a SIP account (SIP calls using native dialer is now possible), DPI could be restored after SIP account settings done.

    UPDATE 5th Dec 2012 by Synman

    ok, I hacked NetworkPolicyManager and am no longer crashing. Network time appears to be non-functional for the time-being. Network status is a little wonky too ... even though I have a good network signal the network icon never switches from gray to blue.
    MMS send/receive is fully functional (with the exception of screwed up timestamps)

    Hallo! Bin über meinen Beruf in die tegra3 Struktur geraten und bin einer Lösung für Telefonanrufe sehr nahe! google hat eine Sperre zum Anmelden in die Zellen der Mobilfunkbetreiber gesetzt.
    Ich kann bis jetzt Anrufe im Vorwahlbereich meines Standortes führen (nur Festnetz), nur noch keine Anrufe erhalten oder zu Mobilnummern führen.

    Ich muß leider erstmal prüfen ob ich hier durch meinen Arbeitgeber oder anderen Firmen Probleme bekomme und hoffe bis Weihnachten meinen jetzigen Lösungsansatz mit Euch teilen zu können!?

    Rough Translation:
    Hello! Here at my job I work with tegra3 and I am very close to finding a solution to making calls. Google has a lock to log into the cells of the mobile operators.
    My progress so far: I can make outgoing calls to numbers with the same area code (landline only), but not receive incoming calls from mobile numbers (Possibly same area code only).

    I have to make sure I'm not breaking any NDAs with my company before I can post this half-working solution.

    Thanks meter is on the left :)
