vakharia 23 Report post Posted March 21, 2014 Hi, After getting a Droid Maxx, I popped in an Idea SIM and realized that it does not allow voice calls. That SIM was actually cut from a normal SIM. I tried the global mode and that has no option to select the network. So I tried the other mode (LTE/ GSM) and that showed me Vodafone and Idea, but nothing worked. Then I manually put APN and data started working. I tried a Vodafone nano SIM (again cut from normal) and that one got data working, but no voice calls, though network bars showed up fine. I thought the cut SIMs are an issue, so I got a brand new Idea nano SIM and popped that inside the phone. That one does not even allow data now. The phone just states No service. I learnt now from a seller on ebay that the phone has to be activated on Verizon first. Then it can be used elsewhere. I am not sure what exactly Verizon installs on the mobile. But question is what can be done to unlock the GSM. I don't have access to CDMA nano SIM's so I cannot test that out. Share this post Link to post Share on other sites

vakharia 23 Report post Posted April 11, 2014 Android 4.4 comes out of factory on this phone now. Update on the issue: An entire IMEI range was missed out from GSM Association's global database. I submitted five such IMEI's belonging to devices in India. Now, the global database is updated. Indian carriers sync with this database periodically. But they can be requested to sync ad hoc as well. Does anyone have any contacts with Airtel/ Vodafone/ Idea Cellular? 1 Share this post Link to post Share on other sites
dev997 62 Report post Posted April 11, 2014 I think u have to keep the phone to 4.2.2 and then both GSM and CDMA RUIM works fine with all calls, sms and data. After upgrades ppl start to have issues. I have a pc on 4.2.2 and it works fine Share this post Link to post Share on other sites
vakharia 23 Report post Posted April 11, 2014 Since the phone comes with 4.4 out of the box, how do you downgrade it to 4.2.2 without having root access? Share this post Link to post Share on other sites

After upgrades ppl start to have issues. I have a pc on 4.2.2 and it works fine your phones must have been activated previously on verizon so they are working coz few of my droids brand new phones are worked with gsm as they are activated and used for 1 day Share this post Link to post Share on other sites
dev997 62 Report post Posted April 11, 2014 yeah mine is pre-activated. Do u know if its working for me on 4.2.2 would it still work if I upgrade to 4.4? I have heard from few ppl that it may cause problem with the update. Thanks Share this post Link to post Share on other sites

vakharia 23 Report post Posted April 22, 2014 So finally, after a month of follow up, it was discovered that an entire block of IMEI numbers was missing from the GSMA global database. Now, that has been added. Indian carriers have synced their database and four out of the five phones which I am aware of, are working. Ironically, only my phone is not working still. But I am on it. 2 Share this post Link to post Share on other sites

vakharia 23 Report post Posted April 24, 2014 Keep up the great work brother. This is something we had given up our hands on. Angelic indeed If you have other phones/ even something from the past, then let me know. Perhaps we can figure out a solution for the older models as well.

vakharia 23 Report post Posted April 30, 2014 Yesterday, Motorola forums support pointed me to this URL: http://forums.androidcentral.com/moto-x/346215-sim-card-unknown-source-moto-x-cdma-verizon-2.html Specifically the post around ICC ID was highlighted. I am not sure if this is relevant to the problem of some phones not working on Indian carriers, but it is worth digging into briefly. Can anyone test 20 and 19 digit ICC ID based SIM cards and report back which work and which do not? The 19 digit ICC ID's may not work as per the post on the AndroidCentral forum. But we have to test to figure out if that claim is true or not. More information about ICC ID is here: http://en.wikipedia.org/wiki/Subscriber_identity_module Another post on Apple forums talks about how 64KB SIM cards do not work and only 128KB SIM cards work. https://discussions.apple.com/thread/3390945?start=270&tstart=0 Harsha had mentioned about this earlier.

I will reach out to all those who had problems with Droid series not working in India (which subsequently started working after IMEI database was updated). If several users are facing this problem, then something in 4.4.4 is breaking support for us. Share this post Link to post Share on other sites
