Do you have a working SIM card from AT&T or T-Mobile in the SIM slot?

Call VZW and ask.

On ebay it's a ton of services about whitestone unlock, and my problem was an issue on the operating band of GSM for example in the USA you must use 950/1900 on other countries like Costa Rica you need 1800, thanks to all for your help

You should be able to contact VZW and have them unlock it so you can use whatever carrier SIM you have for the country/area you are in. The stock SIM is Vodaphone and I think will only work where Vodaphone service exists. Otherwise make sure the phone is in Global and not CDMA only. Go to the Settings Tab, click Menu then select Phone Network Mode select Network tab.

I called verizon and they gave me codes to unlock both my phones. I slapped an ATT sim into my imagio and it was working on the ATT network, no problem at all.

Hi, where do you enter the sim unlock code on Imagio?
Thanks.

I just got off the phone with Verizon in regard to this.
Below is what I found. The Global Verizon Rep will be happier if you enter the code while you are on the phone with them; they want to verify that it works. It actually took about 10 minutes.
Here is what I found: http://pdaphonehome.com/forums/htc-imagio/138569-how-unlock-verizon-imagio-sim-card.html
If you are going to be traveling abroad or simply want your Imagio to be unlocked its very easy to do and should only take about 3-5 minutes on the phone with Verizon.
Call 1(800)-711-8300 from a different phone, enter your Verizon phone number, then select option 2.
Tell them that you will be traveling abroad and plan to just buy a pre-paid SIM card when you get there, and that you simply need the unlock code for your phone. They will check your account standings, and then give you an 8 digit code.
You need to enter the code in the security section of your phone.
With TF3D...
Start>Settings> All Settings> Personal> Security
Without TF3D Enabled...
Start> Settings> Personal> Security
One you do this, soft reset your phone and you are all done. I can take my work phones SIM card (AT&T), put it in my Imagio, and use my Imagio for work now. I did not test the data yet because I do not have data on my AT&T plan. Although if anyone does this and wants to check it, keep in mind you will have to change the number for the data line. both Sprint and Verizon use #777. I am not sure what AT&T or TMobile use.

I have an Imagio from VERIZON.
I had unlocked the GSM network, Should I Unlock the CDMA network as well if I want to use the CDMA Net work?
or I jus need 1 unlock code for both GSM and CDMA?
So, I will have 2 no. in 1 phone one is injected, and another one is using sim card.

“Answered but not Perfected” Getting the Droid 2 Global to work on USA GSM

I was at at&t and we where unable to activate the phone even though the phone is capable. At&t said everything was good on there end but the phone just wont get a signal but it says it is on at&t.
Does anybody have any ideas how to fix this?

Quite a few people (including myself) on various boards have acknowledged having this problem as well. I got the SIM unlock code from Verizon but when I do a GSM network scan, nothing is detected. I know it has been escalated above level 2 support at Motorola and hopefully they will address it shortly. Here's another thread about it over on droidforums: http://www.droidforums.net/forum/droid-2-global/96596-droid-2-global-unlock-foreign-sim.html

Yes, I have unlocked the phone from the code verizon gave me.

I hope its a fixable problem. But I noticed when I use an active tmob sim the phone doesnt even say tmobile. But when I use an at&t sim it atleasts says at&t.

I'm very interested (as I'm sure many others are) in a resolution to this. OP did you call VZW global support and let them know you're having this problem? Hopefully the more they hear about it, the faster they'll have a fix

They where no help at all they said it was for foreign sim cards only and that at&t and tmobile where not supported. But they did say verizon was better than both of them combined.

If you feel like experimenting try this:
Go to dialpad, and enter *#*#4636#*#*
Click on Phone Information, and then scroll down to bottom. Set preferred network type from "CDMA auto(PRL)" to "WCDMA preferred" and see if that kicks it on ATT.

I'm 99.9% sure after looking through the user guide that VZW has restricted use of the 850/1900 MHz GSM/UMTS bands, even though the device has the hardware to support them. Most foreign networks use 900/1800 GSM and 2100 UMTS but AT&T/T-Mobile use 850/1900, which is why no one has had any success with them yet.
Hopefully someone can figure out a workaround.
EDIT: Just a US GSM restriction...looks like 850/1900 work abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

These where the results I got, so clearly it is getting seeing the network. Just not connecting.

Just got off the phone with Motorola and they said the droid 2 global was only for verizon sim cards and when I told them about the unlock code the guy didn't know what they where for. So another dead end. Another theory I have is that the stock verizon rom is blocking at&t so maybe if someone can flash another rom we can see if this is the problem.

Further proof the 850/1900 bands are locked: https://motorola-global-portal.custhelp.com/app/answers/detail/a_id/57058/p/30,6720,7706
"GSM-based global services work only with a SIM card supplied by Verizon Wireless® or by another GSM 900 or GSM 1800 service provider. When you set your phone to use a GSM 900 or GSM 1800 network you may be prompted to enter a subsidy code. To get this code, contact Verizon Wireless."
EDIT: Looks like they're just locked in the US, not abroad: http://www.droidforums.net/forum/dr...d2-global-south-america-first-impression.html

If this is true why would they say it has the 850 and 1900 bands? I know its not a hardware problem, so if its a software problem there is a chance we can have a workaround. Or the locked bands might be because of the verizon rom.

I was able to put a new rom on my Droid 2 Global and although the rom was working since it was for a droid 2 the radio was not working properly. I was not able to force turn it on. I still have several more things I will try tonight.

Keep us posted!

This has been done before on Windows Mobile phones (CDMA HTC Touch Pro 2) and requires a radio reflash since the bands are locked in the radio firmware. I am hoping they will develop a solution for Android phones. http://rhodiumw.htc-unlocks.com/
Being that this the 1st CDMA/GSM (Tie if you count Droid Pro) Android device I would wait and see.

Good info, thanks

As from what I learned from previous devices the Droid 2 Global Verizon has a security locked radio. I have seen people unlock the radios from windows mobile phones, it is as easy as installing a .zip file that will unlock the security. I believe it is the same way with the Droid 2 Global. I will try to get this working but I don’t have much knowledge in the development field. But I do know you will have to be rooted. I have also spoke with a friend at Verizon, which claims that they did indeed lock the radios and there is a workaround. He said he was not familiar with this workaround but said it was close to the problem with the windows mobile security locked devices. I am calling this the official reason the phone wont work with US networks. This makes sense, and now that we found the problem it shouldn’t be long before we find a way around it.

Thanks for the info swangotp...that definitely sounds promising. Keep us posted!

Question to those who have their S4 _successfully_ unlocked by Sprint

Did you received any sort of OTA when Sprint unlocked your phone?
Currently Sprint claims that they just mark the phone as unlocked in their DB and then you need to restart it.
It clearly doesn't work for many, the phone still shows "Invalid SIM" message and the consensus is that this is not normal and the phone is not unlocked.
So the question for those who have their phones _successfully_ unlocked, was there anything in addition to Sprint saying that they unlocked your phone?

You call them (or chat) and ask to unlock the phone to be used with 3rd party GSM carriers. That's what I meant.

no, tmobile and att bands are supported by the hardware.. but are blocked by samsung/sprint regardless of unlocked sim status. if we can unblock it 3G would also be supported. WCDMA band support on the Sprint GS4 includes 850mhz and 1900mhz... so that means 3G works just about everywhere for ATT... and Tmobile would have no AWS band support but would have 3G in areas where Tmobile has refarmed 1900mhz.
Again.. the hardware itself supports these bands... its just an extra block thats stopping us. I am working on the unblock for ATT/Tmobile.
And to the OP @obender, @jj14's post show exactly what Sprint sends when the device is unlocked. Other than that... go thru the steps and that's that. As jj14 also states.. he can pop in a tmo sim and gets no error... proving he is truly unlocked.

I had my phone unlocked, and I did the above as per the email I received. However it just said that the profile had been successfully updated, which was the same thing it said before it was supposedly unlocked when I pressed UICC unlock. It also didn't change to GSM mode automatically. So I wasn't really sure it had worked, but I was able to put in the AT&T SIM from my Nexus 7 and I didn't get an invalid SIM error.
When I went to Costa Rica, I was successfully able to use my phone with a prepaid SIM (GSM and HSPA/WCDMA). That said, I had to go into the Testing menu and force it to use only WCDMA, otherwise it would only use GSM/EDGE (even selecting WCDMA preferred didn't work... it would switch back to GSM pretty quickly). I also had to make a build.prop edit to be able to add an APN to use data. So you basically need root if you want to use data.

You seem to be digging in the unlock for the S4, but are you just working on domestic, or also international unlock. Have anyone tried pulling all the nv items before and after the unlock?

I just recently got my S4 from sprint I had them unlock it for international use all the available networks now show up, but in regards to invalid sim msg I will not know till the end of September when i am out of country. and on a side note if you call Sprint before you own the phone for less than 90 days you have to go through a lot of loops but they will unlock it for international use. out side of that I am unsure as too how far the unlock actually goes.
will keep you updated as to my findings I will be trying a different sim card while over there

Verizon Moto g4 unlocked by Verizon

Has anyone who bought the g4 play Verizon version noticed the unlock policy says either use the phone for one year or make $75 in payments? I'm wondering if Verizon actually unlocks the device will it enable the 3g bands they are there but they're blocked. Has anyone actually had Verizon unlock this device?

How do you know that the 3G HSPA+ bands are present? The specs I've seen only list quad-band GSM, dual-band CDMA, and LTE bands 2, 4, 5, 13.

Ohk I got my Moto g4 unlocked and I actually got it to dial out the problem is I think because my phone is still on it kept taking me to Verizon my service was T-cdma and I couldn't find where I could input APN settings

Obviously the phone is capable of this feature.
Did you get advanced 4g lte after unlocking it with the code on Verizon or because you are using a T-Mobile sim?

Okay, so the phone has the capability but only through T-Mobile it seems.
Verizon and AT&T must have some sort of block on their network so the feature can't be used on the xt1609. Why, idk.
Makes no sense to me.

In order to be able to dial out you have to change the CDMA Subscription to NV if not you'll get "sim error or no sim" but the calls are still over 1x. Also for whatever reason different sims make the phone act differently. At&t sims only give u an option for APN, if you use a T-Mobile sim long as you change the network mode from LTE to 3g or 2g you get options to change cmda subscription, APN, advanced 4glte, search for networks etc. My network was always T-Cdma on T-Mobile long as I changed to NV while on at&t no signal pops in at all

I'm gonna try again once my month is up if I'm not mistaken CDMA is programmed in the phone so that could be a reason I'm having trouble but I also thought that if I remove the sim the CDMA portion would still work which is not the case but either way all my calls are routed to Verizon

Sprint Preordered SM-G950U MSL

So just wanted to let you guys know at least this worked on my end. If you have the SM-G950U preordered S8 and using Sprint, you can edit MSL settings.
1. Go to diaper and type in ##3282#
2. Either view DATA or Edit
3. Type in '000000' as your MSL Code.
Don't know if you can really change too much but I'm going to play around a little.
Let me know if this is helpful to anyone or if anybody has any further suggestions or comments.

Worked for me also. Thanks for the information.

I got it still can't edit the APNS

Yeah not sure why we can't. However, interestingly if we try to access APN list via settings - connections- mobile networks - access point names, I can see a list of 7 APNs. I assume most are only used for OTA updates and if you set your connection. From cdma/LTE mode to global mode. If I then go into DATA Menu and edit mode and click on the APNs then I can only see 2 options (EHRPD or LTE) but I am able to select the one I want and change it. However, I do see that I don't have the option to add a APN. This might be a limitation when using Sprint as the carrier.

Well the thing is that I have a sprint Galaxy S8 with i bought "unlocked" to my surprise it wasn't I have ATT. So im looking to whatever i can t get this cellphone unlocked!!!! Since I don't have a Sprint SIM. I can't edit APNS on settings!!

Hmm well I figured you probably already tried this but earlier if I went to Settings- connections - mobile networks- network mode and changed to gsm/umts I was able to then click manual and search for network and connect to either AT&T or T-Mobile. Not sure if this Must be done first.

I went to Settings-conection- I don't have mobile networks here.
I don't know if you need to have a sprint sim for this. But right now I don't have any sim because Im using ATT and using a older phone to be able to have a phone!!!

Okay so I just tried this option. Go into the connection and network mode and change to automatic. Then had to restart. Once restarted I went back to network mode and changed to gsm. Then I went to network operators and searched for network. Got the error that it must kill data connection before searching. I selected ok and searched. Att and T-Mobile came up. I selected Att and it said it registered on AT&T. I don't have an AT&T SIM so I can't test. However, in the morning of I see my roommate I might be able to try his SIM.

Also you might have to select gsm mode and then do the ##3282# and edit mode first and then go into settings to change network operators. Not sure but it seems ##3282# edit mode must be done to unlock additional settings in the phone.

Don't have conection mode either. I'm thinking you have this enabled because you have a sprint sim in it!!

Did you buy the phone already activated on Sprint network? And also it is a G950U correct? The only reason I ask is because I think the G950U is unlocked but if it was already activated on Sprint, then you might have to factory reset the phone and have the AT&T SIM inserted to have AT&T be your carrier.

I don't know I bought it from somebody locally who said it was unlocked and yes it says G90U but when I insert the sim card it says invalid sim card.
Let me try the reset with the AT&T sim in it to see

When I first turned the phone on it never had the Sprint splash screen until it finished setting up and power cycled. That was the first thing I noticed. Also the phone should be unlocked by default bc this variant is exactly the same for the 4 major carriers. When I checked the firmware both CSC and AP it was the exact same as T-Mobile firmware.

Please let me know if that works. It is just a suggestion and there is so much confusion on this at least from my part. Not to mention not much info on the forum yet. If this works then it might shed some light on the G950U variant.

Did it still the sprint splash screen comes on!!! Waiting until boots full

Hmm hopefully it isn't a firmware issue. I'm not sure if there is an AT&T firmware up on samfirm.com yet

Does not work. Is says please provide the UICC that came with the phone. So apparently when you activate it with a provider it locks!!

Sounds like it might SIM carrier lock. I think the law last year stated that we have to be able to swap phone on any carrier in the US. There is a UICC unlock under settings and software updates but it wouldn't work for me. If I remember properly I had to wait about a month or two before they would let me UICC unlock it. On samfirmware there isn't an AT&T firmware uploaded yet. There should be soon. You could try to wipe and use the T-Mobile firmware as this is GSM and will at least be the network of roam for AT&T. Might at least allow you to use the SIM or at least activate on AT&T

Well checked on sammobile.net still nothing for the AT&T varian, but if you look at the S8+ they already have the firmware for AT&T
