I'm working on a project for work, one of the stipulations is being able to lock a single SIM card to a device - ie; if the phone is started up without the SIM it was provided with, it will refuse to start up unless the correct security (not SIM) code is entered, or the correct sim is put back in the phone.
We are currently doing this with nokia handsets with great success, but we're also looking for more customisable phones.
Soooo.... Is this possible with android? All i've found on my handset is weather or not my phone prompts me for the SIM PIN.
The reason for this is a large number of handsets we're being "lost" and we were a little suspect of how often some employees were "losing" their phones. After we started locking phones to SIMs, far (far far far) less devices were being lost...
If anyone could point me in the right direction, I'll gladly give you an internet high-five!
I am from the Android world, zero experience with WP7 and I want to buy this exact phone and possibly flash a custom ROM
and the goal is to get this to work on Page Plus (Verizon MVNO) and NOT Sprint
the phone is currently set up for C-Spire - a smaller CDMA carrier in Mississippi (formerly Cellular South)
I have access to CDMA workshop and other CDMA tools, such as qpst
I need Verizon coverage and a REAL keyboard at a cheap price ($55/month) and this looks like it could be the ticket!
I had the same question and found a post from bing searches with someone claiming to have succeeded in activating it on Page Plus. Unfortunately the person never really detailed how he did it.
I'd still like to know how it can be done.
The Arrive can be flashed to P+. I'm using one on it. You'll need the paid CDMAWS, not the hacked version.
Also, before you do this, remember that the 3G will be intermittent. The reason for this is that you cannot upload the authentication file to the phone's file system, so the phone never gets true 3G, it cycles between connecting and 1XRTT. To make this work properly, you'll need to have a ROM loaded that's a direct port from the HTC Trophy, or an Arrive ROM that has the Verizon operator package in it. I've yet to learn how to do this, but as time permits, I'll figure it out. I've got a few requests in to ansar and leadpoizon, two ROM Chefs that are heavily involved in GOLD_C (our phone's) development here.
Here's what I did:
1. Put the phone in Diag Mode, using ##MFG# on the phone dialer and connect to CDMAWS.
2. Obtain your MSL/SPC by using the HTC Method, then write it to 000000.
3. Program the phone using CDMAWS just as you would an android device; put in MIN, MDN and set your data settings to your#@vzw3g.com.
4. Load a modded PRL to put the phone on Verizon's Towers, and lose the roam triangle. (Attached)
5. Call P+ and give them the MEID of the Arrive. They'll tell you to do *22890, but do NOT do it.
6. Once they say it's active, make a test call, and enjoy your Arrive.
The steps above will give you voice calls, SMS, and spotty 3G. MMS will not work, unless you hack the registry of the phone. The phone works great with WiFi, though.
If you're brave, try forcing the phone into 1X by finding a non-EvDo PRL. You'll be showing that you're roaming, but it may yield better data results. If you do set 1X though, be sure to set MIP type (in CDMAWS) to Simple IP.
Post here w/ questions, if you have any...

It is fairly easy to install a new D6603 to work completly on the AT&T network. It is not so easy to find the answer of how to do it in the threads and posts. I tried many suggestions and wasted a lot of time. Hopefully this will save you from that fate.
First you must know that you can't use the IMEI number of your new phone if you want it to work completly as it should. If you use the Z3 IMEI you will have trouble with data of various sorts and the phone will go off line when on LTE after 20 or 30 minutes and you will not receive calls or SMS messages. I do not know why but it has been suggested that the AT&T network does not recognise this phone so it causes trouble.
If you have an AT&T nano-sim from your old phone then just put it in the phone. (Cut downs work but can cause other problems some say.) When the SIM is inserted for the first time into a new phone there is a prompt that asks if you want to download the APN. Hit 'yes' and the phone downloads the APN itself.
If it does not ask then go to Settings>More>Mobile Networks>Prefered Network Type and be sure LTE (Preferred) is selected. Then connect your phone to the internet and then go to Settings>More>Internet Settings and select AT&T. You should be good to go.
If you need to get a nano-sim then go to the AT&T store or call and they will give you one or send you one for free. You will need to use the IMEI number from a LTE phone that is already on the AT&T system. You can use your old phone or borrow the number from someone. If the rep installs the sim in the Z3 with the 6603 IMEI don't worry. Just call support later and tell them you sent your new phone back and want to go back to your old IMEI or have a new IMEI (from an existing AT&T phone). They will enter it and off you go. The phone from the IMEI will show in the picture on your account page. Big deal!
Update: This worked for hours last night but this morning it is back to not receiving calls. Simply turning wifi off and it began to receive calls as GPRS was switched back on. My wifi was on which has been said to cause problems. I will test with wifi off and report back. Had "no service" instead of AT&T on upper left of lock screen. A full shut down for several minutes than re-boot solved that.
YMMV. I've been on ATT with a Z3 purchased from Sony store for several months and it was registered in an ATT store by scanning the IMEI off the box followed by updating Internet settings in Setup. ATT online shows unknown model but everything works including LTE and MMS. There is something else involved when problems like this occur probably some setting not getting reset. I registered the Z3 on a new line with a new Sim card because I wanted to take my time moving stuff off my old phone--this may have avoided the problems.

I've also had no problems with my Z3 on AT&T. Works great, receives sms/mms immediately, etc..

AT&T's system sometimes takes a while to get updated with new IMEIs that trigger LTE provisioning for a users' account.
Once your account is provisioned for LTE you never have to worry about it again, but sometimes if you have a phone the system doesn't recognize, it is a pain to get AT&T to properly provision your account. Supposedly properly trained in-store reps can do it - the key being "properly trained" - Never try to do anything "unusual" by calling AT&T customer service, and NEVER use a franchise/kiosk in-person for service - make sure you're at a corporate-owned store! Even then, some stores might have incompetent staff. I've been lucky that all of my local corporate stores are pretty well staffed.
So you are saying that your Z3's with wifi and LTE on with AT&T are working as they should?
With LTE off my phone responds normally with wifi on. With LTE and wifi on it will not respond to calls after a 30 minute sleep. It does not show missed calls. Calls go straight to voice mail after 2 rings. Could you tell me what level your LTE dBm's are? Thanks!
I was told not to give them my imie# but, after recvng the minisim I had to call them in order to 'provision' it to work at all and they needed that #. I have never had any problems personally and am assuming this may be because you gave them the wrong #. Again I am only guessing. Oth, if I had had a different imie to give, I would have done so myself.
It is very strange and I am feeling it is more signal strength related than how you provision your phone. (Once it is provisioned correctly.) It seems that more people have less problems when they already have a nano-sim and just plunk it in the new phone. This might indicate that they already had a strong signal from the get go. My old HTC One + get's a better signal than the Sony in the same locations with the same (new) SIM. With the Devilcase bumper on it gets 5% less. My very limited tests yesterday seemed to indicate that it was signal strength related. I am not enough of a conspiracy theorist to imagine that AT&T would program their system to not function correctly with sims that are provisioned with these Sony phones which they are obviously ignoring for some reason. Or am I?
I had all kinds of problems with the Z3 on AT&T. The IMEI caused an issue since AT&T linked it to a flip phone and therefore couldn't provision LTE. I changed it to an old AT&T LTE device and then I was able to get LTE but was having the same issue with calls going directly to voicemail and texts showing up hours later in bunches. I found the solution was to switch off LTE in the quick settings menu. All calls and texts came through and on time while LTE was off. If I needed a data boost to stream, I turned it back on until I was finished streaming. This was while on KitKat. After upgrading to Lollipop, I was able to keep LTE turned on and calls and texts still arrived on time.
I use data rarely. Mostly wifi. If I don't leave LTE on, my phone reverts to wcdma preferred. And why can't LTE just work without me having to constantly turn it back on? What bugs me is having the APN settings greyed out. I want to be able to turn it off. If anything it seems the phone itself is preventing me from accessing the sim. It feels like I'm borrowing something which contains lots of MY private data. I know my phonebook is stored locally but I also noticed there is no option of specifying the sim or not. Anybody know how to switch APN on and off? In fact, overall even rooted, I still feel like I have almost no power over it. I can't even disable the cellular connection without going full on airplane mode and I do not trust that. I don't even fly so that needs work for sure. Dumb question but could I buy a working nanosim from say 7-eleven that my apn switch will work with?
"Anybody know how to switch APN on and off?"
On my Z3 on OTA stock Lollypop I have an icon in quick settings to turn LTE on and off. Drag two fingers down from the top of the screen. If no LTE icon then select the pencil icon at the top and select the LTE icon. There is also a mobile data icon switch there.
To turn off your radio completly you can get the Advanced Signal Status app and select additional info at the bottom and click phone information and turn off radio. Probably a number of ways to do it but that is one.
Sim contact storage was a way to move information from phone to phone. You can still do it but not really necessary with cloud backup and storage. Google does it for me without me having to do anything which I like. I still save contacts to the sim just because I can. Export and import in your contacts app menu.

Works fine here. I don't pay attention to the dBm estimates since these aren't measured with calibrated test equipment and vary widely. Those numbers are basically worthless.
The only valid comparison is data performance in a given environment (ideally a difficult weak-signal one) - and at my desk with very weak signal, every phone I've ever used performs similarly to the Z3.
"Those numbers are basically worthless."
True, but we have narrowed this down to the possibility that it might be signal related so it is worth a shot. If people whose phones are working fine would measure the LTE dBm on Advanced Signal Status at the location where their phone sits and works well the most we might possibly see some measure of difference in the phones that are not working. Most of the non-working phones seem to work sometimes so signal strength is the next best parameter to rule out. Thanks!
Here are the screen shots of my phone with LTE on, LTE and wi-fi and LTE off and wi-fi.
How do the working phones compare? Does your CDMA (voice) also go to 0% when LTE is on and GSM = n/a?
Thanks. I think adv sig nfo actually works. I'm amazed actually. I can't find the phone's native greyed out apn switch anyways which really makes no sense.
Hello everyone, new to xda and new to any advanced android fiddling in general.
I bought my Flex 2 off ebay and to my surprise it came unlocked already. All sprint would help me with the unlock is giving me the msl number which I could not find what to do with it, so I used this guide to change the node database and node journal to allow the phone to be used on tmobile. It was getting almost no reception except for about 10 seconds when I made a test phone call, then again no reception for a while, so I also used this guide to enable 4g roaming. It now calls and sends mms fine, but live in the united states and rarely travel out so I doubt that second change had any effect and I just had to wait a while to start working with tmobile. I still need to add apn to get internet working though.
My question is if I make all these changes, then update to 5.1.1, will it remove all of these changes and make it unusable with tmobile again? I know it removes root otherwise I would have no problem updating.
after update you'll loose root permission. and you'll not be able to add apn without root.
GSM will work , but CDMA wont.
Hey guys, I’ve recently entered the android headunit world and purchased a android 10, 10.1” joying headunit (octa-core 1.8ghz, 6gb ram 720p).
The headunit is fantastic and exceeds my expectations in every way, except the 4G mobile data function doesn’t work.
I’m from Aus, so I’m using a verified working 4g mobile broadband Telstra sim that is a GSM type (which joying says is compatible).
The unit detects the SIM as it should, identifies it as a Telstra sim, shows full 4G signal in the top bar however it has no data stream.
I have the mobile data function enabled, roaming enabled, no data saving features turned on and have made sure to set all my apps to unrestricted access.
The interesting thing is, if I turn the headunits hotspot feature on, and use the units 4g network as a hotspot and connect my phone to it, everything works perfectly and it shows a perfect data stream.
However the unit itself cannot use its own data.
I have followed all of the instructions given here:
Android car stereo, Android 10.0 Head unit
How to solve the 4G problem on Joyin --> How to solve the 4G problem on Joying head unit? Following ideas are for solving the 4G problem when there i
www.joyingauto.com
But seeing as how the unit can actively stream 4g data via the hotspot function, there doesn’t seem to be an issue with SIM card settings or anything hardware related.
Has anyone come across this or have any idea what I should do next?
(Let me know if you need any unit details)
I don't know if this will help because you said your hotspot works but have you checked your APN (access point names) settings to see if there are two options to switch between?
There was only one in there which was the default automatic setting. But I figured that if the headunit could still send and receive data via hot spot to another device that the APN must have been correct?

Yeah, that's what I would have figured too. But I'm not an expert. Is there a DNS setting you could change? Perhaps add a custom DNS hostname such as dns.quad9.net ? I'm just guessing here.
I’ll have another look tonight but I don’t remember seeing any settings to change the DNS host name.
I was able to hotspot data just fine however the headunit had no internet.
Verify that the acces point names (APN) are set correctly. I had to copy the settings from my phone (using telstra) and apply them to the headunit.
This can be done by going to Mobile Networks > Access Point Names > [first one in list]
I had to change APN to telstra.wap and APN Protocol to IPv6. Also, there's a bug where the text is white on the input box. Have to select it to read it.
This worked with both the newer Android 10 (universal 10.1") and older Android 8 (Honda acord kit) on telstra data sims
Absolute legend, thanks mate.
I’ll try that tomorrow and see how it goes!
Thought I’d let you know it worked a dream, just had to change the apn and the protocols.
Thanks again!
I ordered a JY-UQD11N6G about 10 months ago and since then I have tried EVERYTHING that has been suggested here and by Joying. I've tried the universal build from FYT from this very informative post. The head unit recognizes the SIM and properly populates the APN data, but for some reason the time on the device sets back to the build time and date of the ROM every time the device reboots. I have also deleted the prepopulated APNs and created a new APN according the information on my phone when the SIM is inserted and functional which corresponds to the information here.
It does get (or keep) the right time zone, but it will not keep a persistent time through a reboot with a consistent power source.
Joying has sent me an unreleased ROM that doesn't fix the issue. I've tried different external antennae and I've torn the device apart to ensure that the internal antennae are properly soldered to the carrier board (they are). At this point I'm tired of paying $30/mo for a line I can't use.
I just noticed two one pixel wide green lines vertically traversing the LCD, but before I request a warranted replacement, is there anything else I should try?
I tried 4 different SIM cards. T-Mobile pre-paid didn’t word. The head unit recognized the card and everything looked right but no data. T-Mobile post-paid card taken straight out of a display phone in the store worked perfectly, but the cheapest plan was $40/month, and that’s too much. The Verizon card I took out of my iPad and tried did the same as the pre-paid T-Mobile card.
The 4th one I got is from Mint Mobile. Since they use the T-Mobile network, I thought it was worth risking $45. From their website I bought a SIM card with the 4GB phone plan at $15/month for 3 months. It works perfectly! After 3 months I can renew the plan for 12 months and stay at $15/month. 4GB is more data than I will ever use in a month just streaming my music, navigating and doing a few other things, like checking weather/weather radar.
Go with Mint Mobile. It may fix your data issues.

I tried Mint and had the same positive experience, and a Visible (Verizon mvno) card did not work.
But it had bars and showed me an lte connection, it just didn't give me any data. Apn settings were blank, but also wouldn't let me change them, oddly. I'd like to try again as I'm sitting on a visible sim for the next two months that would be cool to use but wondering why some carriers work and others don't, even if they are the same carrier (mvno vs non)?
I have Verizon working on mine, you have to add the APN settings manually via an app from the playstore. However....the device is unknown to verizon so they keep adding it as a phone to my account....for like $50+ a month...I told them i just want data and it should be classified as a connected device.

what provider? what are they charging you for on your account (device type)?
I haven’t used the data service for a while since I started just using apple car play, however my Carrier was Telstra (Australia) and it was something like $15 a month for a
2 GB 4g data sim.
At least as far as I can remember, it did have a mobile number associated with it so I think they were classifying it as a phone plan.

What’s the APN app you got from play store?
I used an app called AddAPN on the Playstore for my Joying and it worked well.
AddAPN - Access the Add APN se - Apps on Google Play
Brings up the Add APN page directly without going through settings
play.google.com
Because the settings app doesnt allow access to edit them...the app edits the apn information since the stock settings app doesnt allow this for some strange reason..
