I got my lovely droid 2 global (white) today, which is amazing. However, when I turned on the phone, it required me to activate. How can I activate it in Toronto, Canada without in US? Thanks.
Exit that wizard, switch to GSM/UMTS and you are ready to go (assuming you unlocked)
hi all,
i've been using my lovely Droid 2 Global outside US for quite a while (unlocked and using GSM network), and it worked all fine till today...
i tried to install fission today, and it didn't work for me (it just won't boot up), so i restore to 2.3.29, and finally managed to boot it up...
but after i power up, and enter PIN for my SIM, it requires me to Activate the phone...when i hit Activate, it immediately show "Phone Activation not supported on this network"...any suggestion on what i should do? i think i have the unlock code that i got from the buyer, but the phone doesn't even give me a chance to enter it!!!
i don't need to use Verizon network, i just want to use my D2G under GSM!! Please help!
i should have asked: why i need to re-activate again simply bcs i restore from a SBF??? I thought it shall stay as activated and unlocked once it was done...am i thinking wrongly?!
Don't freak up. Activation is only for CDMA radio. Every time you do factory restore (wipe data) CDMA programming gets erased too. GSM radio doesn't need activation. Simply ignore this, switch to GSM/UMTS mode and start using your phone.
If you have US account and you want to reactivate so you can use CDMA roaming feature, you need to do manual activation, but you may need Verizon's support to help you with some numbers you need to put up in programming.
BTW - the boot loop happened because you didn't wipe data after SBF. Fission (and any other non-stock ROM) will cause boot loop if you don't wipe data after SBF flash. (SBF flash process does not wipe data as part of the flashing).
GSM radio need to activate to use outside USA ! You need to contact with Verizon to get unlock code or use some unlock sim

You are mistaking unlocking with activation process. On GSM you activate the SIM card (Subscriber Identification Module), while on CDMA the "SIM" is integrated in the radio, hence you activate the radio.
For Droid 2 Global since it has essentially 2 radios - a GSM and a CDMA one, for GSM you need active SIM card to activate and for CDMA you need to make sure phone's MEID is active on your Verizon account then you program it (activte) either automatically while on Verizon network by dialling *228 or manually by calling Verizon support.
For the GSM radio in D2G, in order to use non-Verizon SIM in it, you need to unlock the phone first. Once unlocked, phone remains permanently unlocked and no SBF or wipe or anything will change this status.
Hey guys. I just bought an unlocked D2G on ebay so I thought I would share my experiences.
I got to the same screen where I was told "phone activation not supported on this network" and it was extremely frustrating. my only option was to hit ok and go back to the "touch the android" screen. I tried everything including the menu button. Nothing worked. This was with my SIM card inserted.
So I took out my SIM card and tried again. this time the menu button worked; it brought up the wireless options menu. I wanted to switch to "GSM only" as I had a feeling that would fix the problem. But I was told "no GSM card, must use CDMA mode". So, feeling stuck, I called Verizon, and after waiting on hold with the first CSR, and getting about 30 seconds into the phone call with the high up tech guy, I was in the middle of telling him about how in CDMA mode the wireless options menu would come up, but not with a SIM card inserted, the wireless options menu actually did come up. So I switched to "GSM only" and I was in!
Well, sorta. I had to get the phone linked with my google account via wifi, because the phone had no internet at all. A quick search of the internet revealed that this was a common problem - "I can talk on my D2G, but no data!" I called Rogers and sure enough, there were some settings I had to change to make this work.
Go into wireless options, then mobile network settings, then GSM/UMTS options (I assume you have a D2G because you want a droid you can put your SIM card in, right?) and then to Access Point Names. As this phone is unlocked, there are no APNs listed and your phone is neutered until one is added. I had no idea because my last phone was straight from Rogers and was of course hardwired to know this stuff.
Setting up the APN is really easy. just give it any name, list the APN as internet.com, MCC is 302, and MNC is 720. That's all. Back out. You will notice nothing is showing there. Don't do it again. It's there, but it's not showing up until you reboot. On my first reboot I had the 3G icon pop up in the notification bar and just about filled my pants. finally, the phone I paid $400 for was fully functional! No issues since then. Smooth as butter.
Thanks for the information and sharing leobg and seventieslord!
Gingerbread's rolling out, I'm planning to update my dad's D2G, but we're outside the US with an unlocked phone using GSM. I was worried after updating to Gingerbread, the phone would ask for a reactivation. This thread put my mind to rest

The activation bit is for the sim card, I have a phone locked to O2 and what happens is you register the sim with them and then they enable it to use their network which is why until then it will say no network.
It is also the reason why if you put any other sim in the phone, and that sim has not yet been used to make calls, you get the same error.
As for the personalisation message on the unlock menu, I am unsure what you mean by the lock menu. I assume you mean the screen you see before you unlock your phone to use it each time, and did a search on google which produced no results but I would guess that if you are using a custom rom the message means you either have not personalised your screen or that the option is there to personalise it but has not been used.

unlock menu - where you enter the network unlock code.
i'm trying to use my 3 uk sim, its been on contract for over 2 years.
I know that a lot of unlocked phones wont work with 3, if you google 3 unlock you will find a lot of people have problems and some unlock companies even specify they wont unlock to 3 network but if it does the same with non 3 cards or only works with one operator perhaps the unlock was only partial?
I did a search for pedsonalisation and all I found were various unlock sites saying that a sucessful unlock needs you to have a personalisation menu.
My previous android phone had a device lock and a sim lock, could it be your unlock has only partially worked? Is it only one provider whose network you can access?

you're being really helpful so i give thanks.
i have tried o2 and vodafone sims in the phone also but to no avail... always says emergency only or no network, with both showing no signal.
would flashing the original orange rom back then retrying the lock code help? as of right now when i go to the unlock menu and click network lock it prompts a message stating my phone has no personalization.
sorry missed out a little bit of info.
the only network that works is orange, it gets full signal and works perfect, but i'd really like to use my contract sim instead of pay as you go extra on orange.
I've done some more searching and found that on a lot of phones that personalisation message means the phone unlock has failed and that after a successful unlock it should say something like "network lock has been personalised".
You do only get a certain number of tries so don't enter the code over and over, if you are sure you entered it correctly it means the code you got just didn't work (I had that when unlocking my previous LG and had to buy a code from somewhere else as the first one didn't work at all).
I am not recommending this site, it's just one that explained how to unlock so am posting a link in case it helps, but the site says you need to enter two codes on an Optimus 3D. One is for network lock and one for service provider lock, I know that some people on the xda forums have unlocked their phones so I hope they will jump in and help solve your problem as really all I can do is google for the bits I am unsure of but it would seem your code did not work, or that you need two codes and only had one.

just wondering if i could post a video link here to show how it happens, if not, mods can you delete this link:
http://videobam.com/YqMQH
might need to tilt head/computer screen
that was with orange sim, without orange sim it shows no signal and no network... its running thais rom.
heres a video of it using another sim.
when i start the phone with other sim, it prompts whether i'd like to use mobile data or not, but no connection!

Well having watched your videos I can clear up something, I think.
I had searched for terms based around "no personalisation available" which means your code did not work but searching for the actual message in the video "your phone is not personalised" produced completely different results.
That specific message means the option you are clicking on is not locked (not personalised by your provider) at least according to various pages I have found including a few on other well known Android forums so if that's correct your unlock did actually work and that is why the message appears.
The page at http://www.cpkb.org/wiki/LG_enter_NCK_code also mentions this code and its cause.
If the other sims you try offer you data or mobile but do not connect, yet you can make calls, then you need to set up your apn for that provider. The apn tells your phone how to connect to your provider.
This is really easy to do but you will need a free app called Apn global from the android market at https://market.android.com/details?id=osatek.apn.global obviously you need it on your device which can be done in various ways, possibly easiest if you can connect via wifi and go to the market.
Install and run it, pick the name of your provider (the provider whose sim you wish to use) and it will create the mms and internet settings for you. Then mobile data should work.
Alternatively if you have an android phone which you already use that sim on, install to that phone and choose the apps backup option which will backup your exact settings to sd card so you can import them to another android phone.
If you have other providers apns on there you will probably need to tell the phone to use your new settings. Simply go to your phones settings menu, find the wireless settings option and click it then scroll down the screen to "mobile networks" and click that. Then click "Access point names" and choose the desired provider. I have three on my phone and you can always revert to any other settings if you change provider later.
The apn app is very useful, I have used it on a few phones, it has a large list of providers worldwide so you should find your choice of provider there and hopefully that will solve your problem.
Dave
Thanks for the reply dave, but I have yet more bad news sadly.
I can't actually make calls, as shown in the second video it shows no network/emergency calls only.
It's hard to believe no-one else has this issue.
I have owned lots of android in the past(started with g1, then hero, then jumped to zte blade then galaxy 1, now this) none of them posed any difficulty removing network lock.
Its such a strange problem that a search of this forum shows at least one other person had this issue but no-one could help.
Sorry if this sounds stupid but have you gone into the settings menu on your phone (Settings/Wireless and Networks/Mobile Networks/) and chosen the "select your network provider" option?
There you can force your phone to use a specific network provider.

I have with error "Unable to connect to this network at this time. Please try again later."
I don't think I can help, though I did some more googling and on the cyanogen mod forums someone posted a similar problem....
I've been using the nightly builds of CM7 since they came out and have had no network problems. I then installed version 7.0 [stable] when it came out, and just yesterday I installed version 7.0.3 [stable].
I have had no signal since, and whenever I try and select my network from the Settings > Wireless & Networks > Mobile Networks > Network Operators, it comes up saying "Unable to connect to this network at this time. Please try again later.".
It is nothing to do with my network provider, as my brother's phone works fine and he is on the same network as me.
I am on Three Mobile.
Please help!
RESOLVED: I just wiped all userdata and reflashed CM 7.0.3, I'm a very impatient person

If you fail to get a solution this option may help but probably best as a last resort. One thing I did notice when watching your second video is that you have the wireless on, this will stop your phone connecting to any providers mobile data so at least as far as mobile data goes you won't be able to use it when connected to wifi and would have to switch wifi off in order to test the mobile data connection.
Also I know that on my O3D my wireless sometimes seems to cause my phone signal to switch off with the little x. I doubt that is the cause of your problem but may be worth trying to connect with no wifi.

I'm going to try reinstall the original orange rom that came with it and downgrade baseband, if that fails to work after a full reinstall using lgflashtool I'll have to try get another phone.
thanks for all your help dave, i really appreciate it!
A popular unlock site says the only steps needed to unlock to any network are...
1. Input a non accepted simcard
2. Phone will display enter “Sim network unlock PIN” or “Enter Network Unlock Code”
3. Input the 8 or 16 digit unlock code that was emailed to you
4. Phone is unlocked!
If you did this, which you obviously have, your phone is unlocked and the problem must be something else but if you're going to flash a copy of the orange rom you might want to check first with one of the more knowledgeable users here that the rom won't replace some of the locks you already removed.
I checked around and from what I have found it should be as easy as put the new providers apn on your phone, select their settings from mobile networks menu for provider and also mobile data and that should work.
One orange customer who unlocked a different model android phone found that all they had to do was flash the radio only (not the rom), not sure how you do that but there are probably guides on xda.
Dave
I flashed the original orange rom and after flashing the froyo basrband it suddenly worked. Flashed gb again and it still worked, seems i just hsd to reflash basebsnd/radio like you said.
Thank you so much

Hi pauliebb,
I have the same problem that you had. I bought a used unlock O3D vodafone ES to gift to my brother, he lives in south america and he told me that the mobile does not recognize his SIM. What did you exactly do you did to reflash the baseband firmware???
I supposed thet the mobile is unlock because it shows the same message when enter to the unlock options "phone is not personalised"

i have the same problem, i have phone from plus gsm poland, phone is not personalizet but read only sim card from plus, diffrent card not read and show info no sim card, help me how resolve this problem?
Is there any way to bypass simcard check on a a samsung admire 4g and use the cdma service only?
I have a samsung r820 that i bought second hand.The carrier is metro pcs. I don't have the micro sim that appears to have origianally come with the phone. I already unlocked the device to use with another carrier and flashed a new prl. the device didn't get service because the sim was missing so i installed an app named "switchit 4g lte toggle" from the market which allowed me to turn the the radio on. I have service now but i cant make any calls because a pop up window keeps appearing "insert Metro PCS SIM Emergency calls only" whenever I attempt to make a call. Is there any method to stop it from doing a sim card check or for it to think there is a sim card in it?
I already asked this question in the noob friendly section but i didn't get a response.
Update:
I bypassed sim check by glitching the phone. I used anycut to create a short cut to the activity labelled Attention. then I launch the shortcut and quickly slide the notification area downwards. it takes a few tries. the only inconvenience is something like a debug widget that stays on top of the homescreen. I now have service and the insert sim is off. hope this helps anyone that has the same problem.
Having an issue with a newly picked up at&t P907a and looking for a little help.
Love the note pro but when I add a sim the pro recognizes that it has been inserted and a pop up asks to be restarted to connect to the network.
Once restarted it simply says 'no sim installed' and won't let me into the mobile networks part of the android settings to change any networks etc..
Running stock at&t as it has been factory reset.
I've been assured this pro is unlocked but starting to have my suspicious...
Anyone else come up against this?
Thanks.
Call AT&T or go on their website and do live chat, they will look up the IMEI and can unlock it for you.
https://www.att.com/deviceunlock
Thanks Jargin,
So the issue I'm having is because the pro is not unlocked? Have you had the same issue with it saying no Sim installed?
I've been told that if you put in an unsupported Sim in one it will ask for an unlock code rather than just displaying no sim..
No after reboot my device asked for an unlock code. I would take it to a store, maybe someone entered too many won't pin codes, that can happen too.
Hi all. I just bought a S10e (G970U, Snapdragon) from China in order to use it in Spain, with Orange as a carrier. Once I set it up, everything worked fine for about 20 seconds. After that, the mobile data locked down. When I try to turn it up again the device says: "Security policy prevents use of mobile data". I tried to factory reset it several times, try different google accounts, try different SIMs, erase the data from some SIM- and network-related apps, but nothing changes. I guess that this has something to do with Samsung Knox.
What should I do? Is recommendable to contact Samsung support? Can I flash another firmware/ROM that fix this issue? Thanks a lot, any help is appreciated.
PS: Calls and SMS are also locked.

Hi. Thanks a lot for your help! I tried it and nothing changed. Indeed, the security policies were already updated out of the box...
I had the same problem. I had a signal but could not send/receive SMS or calls. After talking with carrier tech support and Samsung, I went to a UbreakIfix store, where they told me the 10e phones have a problem with the antenna on the motherboard. They said I needed to send the phone back to Samsung to get the mobo replaced. I just sent it back to the seller and bought an S20.
Also on S10+
I'm having the same problem on my GM-975U1 S10+. Basically mobile data and texting works long enough to authenticate into the Samsung account during setup, but once the android home screen appears after finishing the setup I can't place any calls and trying to enable mobile data gives a "Security policy prevents use of mobile data" error when attempting to enable it. Neither AT&T or Samsung have given instructions on how this can be fixed. It's behaving similarly to if the phone's IMEI were on a blacklist, but I get immediately shut out once the setup process completes.

I haven't found one yet either. Apparently the phone I purchased is locked to Tracphone after paying for an IMEI lookup (got scammed by an ebay seller who said it was the unlocked model), and the phone isn't able to do calls/mobile data properly except during the initial setup. Tried with SIM cards from two different US providers that both aren't working on it, and can connect to wifi just fine. Can see in the phone information test menu by dialing *#*#4636#*#* that my sim is being recognized, shows my phone number and IMSI, can switch between network types and see the cell towers it connects to; but isn't able to send/receive calls or mobile data. It fails the Ping test with 'Fail(2)' and HTTP Client Test with 'Fail: IOException'.
It's also showing that the phone receives a call inside of the Service Mode menu by dialing *#197328640# and going to '[1] BASIC INFORMATION'. Placing a call from another phone shows that my S10+ is picking up LTE bands and has some RF parameters that change when my number is being dialed, but don't get the option to pick up the call. It's also able to detect that I have a voicemail but am not able to dial in and listen to it. The Tx Pwr says '-- dBm' so I ultimately can't tell if it's a software or a hardware problem.

I am facing the same exact issue my sim number it shows inside the phone and signal I am getting is in negative dbm also my sim receives calls during the initial setup and as soon as the setup completes the LTE network goes away call gives error " call not sent". I am irritated by this now and there is no root available for this model so I cannot flash any custom rom to check. I have seen many people have same issue but no solution yet.
If your phone locked to a particular network, ie TracFone,AT&T, TMobile, Cricket, etc, then that is only network it will work on. Doesn't matter what custom ROM you use. You will need to get the network unlock code either from the network it's locked to or from a reputable online unlock site. Good luck getting it unlocked.

my device is already unlocked. It is not an unlocked phone issue. This is some stupid policy which is preventing from making calls or using data. Maybe this policy is saved in EFS don't know.

That's strange, it's acting exactly like a network locked device. When you say it's unlocked, are referring to the bootloader or network? Did you buy it new, unlocked from a reputable dealer? Check the firmware and make sure it is unlocked. There are other thread here with the same issue and message, those are all network locked phones.

I don't know I bought it from mercari that seller told me it is tmobile unlocked, but while checking I found the model number is G970U1. csc is XAA and binary U4. Bootloader is locked. Networks seems to be unlocked as when I put it my sim card it works till initial setup screen and then stops working. I searched it maybe locked to Consumercellular but is there any way I can unlock it ? I didn't find anything online.
Sounds like the seller lied to you.
Is there any way to unlock CC device ? I am on Binary u4. I am able to flash both g970u and g970u1 firmware but no success.

My S10+ model G975U is network unlocked, with the bootloader locked. I bought a network unlock code, but am getting the same behavior where the intial setup allows me to sign into my Samsung account when putting in both an ATT and T-Mobile sim card. I've also tried reflashing it with several different firmwares both carrier locked and unlocked, but this phone has been sitting in my drawer for the past month since it's unusable. Probably will end up trading it in since I was scammed by the random ebay seller I bought this from.

I'm having the exact same issue. Bought s10+ off ebay for 200 locked to consumer cellular. Bought an unlock code. It said unlock successful. Now get this error with any sim. It will show lte during initial setup only.
It will show that it's at&t or verizon when I put the sim in and populate the proper apn settings.
Before the unlock I would get the sim not provisioned error.
I did have to look up the dial code to make the unlock code window appear.
Now i can't actually use any service and i get the security policy error.
Finally was able to find the xaa firmware which seems to be the exact firmware on it.
Then lash that as no other u1 firmware would flash.

Hi all. I just bought a S10e (G970U, Snapdragon) from China in order to use it in Spain, with Orange as a carrier. Once I set it up, everything worked fine for about 20 seconds. After that, the mobile data locked down. When I try to turn it up again the device says: "Security policy prevents use of mobile data". I tried to factory reset it several times, try different google accounts, try different SIMs, erase the data from some SIM- and network-related apps, but nothing changes. I guess that this has something to do with Samsung Knox.
What should I do? Is recommendable to contact Samsung support? Can I flash another firmware/ROM that fix this issue? Thanks a lot, any help is appreciated.
PS: Calls and SMS are also locked.

I'm from the Philippines and my niece phone is network lock ( Smart Telecom ) I can use the sim 2 slot since it's a dual sim using another network Simcard, unfortunately, it won't allow me to use mobile data so I tried unlocking it *#272*IMEI FROM SIM 1 SLOT# so I choose GLB for globe network or XTC to openline so here's what happens, it got reset so upon set up yeah other sim works have data but when finish setting up everything I can use data again on other network and a message pop up
Security policy prevents use of mobile data
so I guess even it allows other network Simcard on network lock phone it needs to be unlocked by the network where it was lock
Did anyone ever find a solution to this problem?
I'm having the exact same problem with a new samsung s10e I just bought. Security policy prevents use of mobile data, and no calls or sms will go through. LTE shows on setup, but disappears as soon as setup is complete.
I initially assumed the phone was locked, but the seller is reputable and insists it is unlocked. It's also a U1 model, and an IMEI lookup appears to show that it's unlocked. In connection settings under mobile networks, i'm also able to select multiple carriers, so I'm inclined to believe that the device really is unlocked.
Anybody here ever manage to solve this problem, or am I SOL? I would hate to be out 200 bucks on this phone since i'm past the return window.
I am having same isuue with samsung not S20 ultra (SM-N986U1) I bought the mobile and its unlocked the seller send to me photo for the check screen and its open USA but can not use mobile data and make any calls when a make a call the call ended and give me screen call not sent

Yes, there is a solution, but only from an experienced professional 3rd party business, which means there's no free solution
