[Q] HTC HD2 wont connect to A&T network

I recently bought a TMOUS HTC HD2 and unlocked it to use on my AT&T network. However after unlocking the phone and trying a few roms I still am unable to connect to my AT&T network. I did unlock the phone on the stock winmo rom. And when I say i cant connect to the network I don't mean internet or mms. Not a single network function works, that includes calling, texting, mms, and internet.
Any help would be very much appreciateed. :fingers-crossed:

got any other sim cards available to try? (unlocking unlocks to all networks)

SIM cards
Well I have some old Tmo cards that I have from my old Tmo account. And I have a few other AT&T cards that are activated. Currently I have used one of the Tmos cards and one of the AT&T cards but they both do the same thing. It is rather frustrating. Do you think I am not picking up any of the EDGE signal the phone needs to work?

no, its not that, edge is just a manipulation of the 2g network, there is no 'edge signal', there are only 2g or 3g networks (simplified, and not really accurate/true, but close enough for this purpose)

have you EVER seen it working? id be tempted to think it was broken / blocked.

No I did not check before. Isn't there a way to tell if it is blocked with the imei number or something. I hate to think I bought a bad phone. If it is blocked is there anything I can do?

not sure, sorry. I'd maybe give at&t / tmo a call, see if they can offer any advice based on the imei.

Thank you for your help. One more thing the siginal bar at the top shows I have no signal but it has an x over the bar indicator. (I'm running gingerbread sense) When I drag the top bar down it says no service. Would this happen with a blocked phone?

No clue, sorry,

[Q] Using Verizon Galaxy Note 3 International

Can someone Please help me figure out why I cannot get service on my Verizon Galaxy Note 3 when I'm traveling or specifically in India. I thought Verizon Note 3 is world unlocked out of the box!!! Am I wrong?
BACKGROUND:
I have successfully flashed my Verizon Note 3 to Boost Mobile so that means I used a Samsung Galaxy Prevail as my donor phone which means I changed the MEID # of my Note3. I have also successfully rooted the phone and have also installed Beanstown106 leaked version of KK 4.4.2 on the Phone with the latest Safestrap and it works fine as far as I can tell. I used the instructions from the following thread to flash my phone to Boost; just FYI:
http://forum.xda-developers.com/showthread.php?t=2060085
QUESTION:
I try to insert the GSM SIM card for Vodafone carrier and it's unable to connect to network even though I added the correct APN settings. So does this have anything to do with me changing the MEID# on my Note 3, is this why it's not connecting to a network?
I kept getting the error message that "This SIM card is from an unknown source" So I disable the setup wizard 1.0 using nobloat app and it got rid of that message. I'm still unable to connect to a network?
Can someone please tell me what I need to do to fix it or can tell me what the problem is?
Or if there's anyone that has used the Verizon Note 3 overseas successfully that can tell me what I'm doing wrong?

purchase a local SIM from Airtel with a 1GB 3G package and 200 minutes of talktime for about 700 rupees ($10 or so)!!
When adding the new SIM you will see message "Non-Verizon SIM detected" but apart from that voice should work just great. Go into the APN settings the + now active and add in the new APN settings for Airtel. After you do this the internet will start working and you will be able to get H/H+ speeds there.
So yes, Verizon 4G LTE phones are truly unlocked for oversees use and you can just pop in a foreign SIM and go no worries...

Yes it may very well have to do with a IMEI change. I didnt think it was possible to change the imei.

So why would the Airtel SIM work and Vodafone will not? I don't get it they are both GSM carriers so why would one work and other one wont? Even though I fixed the APN settings for the Vodafone SIM.

My mistake, I meant I changed the MEID# not the IMEI.
But apparently you can change the IMEI# of the device as well, allegedly according to the following thread. I never done it myself.

That could easily cause you issues if your carrier can't understand the identification information your phone is providing the tower.

To be safe keep a log of what you have changed that way if it is worse you can know how to go back or what you have played with otherwise as with myself once time passes I completely forget all the details.

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.

No problem. I'm not really sure what would be beneficial to change but it is good that we ha e the access.

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.

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

Samsung Galaxy S7 Edge Issue!

Hello,
I have a big issue with SMG935V phone. I purchased the phone in US, and I am now currently living in Slovenia, EU. The problem is I can't connect to my local network with my local SIM card. Whenever I enter my local SIM, the info comes up, that says: ''This is not a Verizon Wireless SIM" and the network goes gray, I can't select a new network. I tried entering Access Point Names, but to no success. Last month when I was in US, I brought the phone to Verizon Store, where they guaranteed me, that the phone is unlocked and should work properly even in Europe.
Does anybody have an idea, what should I do?
Thanks in advance.

Have you tried contacting the website you used for unlock and asking for support? Perhaps this is a common issue that they know how to resolve easily.

Heres the issue. Sprint is a CDMA network, Family Mobile is Powered by T-Mobile, a GSM network. The odds of a sprint device working with any other carrier that isn't CDMA is next to none. I work at T-Mobile and we run across this issue frequently, sprint devices aren't compatible with our networks because of sprints difference in network hardware.

Ive unlocked the phone and it has a CDMA or a global GSM option so i doubt thats the issue. However it seems my actualy issue was that the person who sold me the phone only reported it stolen or missing once i bought it from him.

Take the device to a sprint store and have them run the IMEI, they can tell you. Having it unlocked doesnt mean its GSM if the hardware doesnt support GSM. I have that issue with sprint phones all the time.

The ls997 is gsm compatible, the only thing it wont do is Voice LTE, this will only work on sprint. Most sprint phones use sim cards now days, so the majority of sprint phone can be unlocked to be used on a gsm carrier.

Then you need to manually setup the APN settings for the data.

I am still dealing with Sprint now but i don't think they know what needs to be done.
MY device LG v20 (LS997) did received unlocked code.
I did update PRL, Profile, and UICC unlock button in System update .. and it did all without any error.
However when I insert NON-Sprint SIM CARD, the device can't recognize the SIM CARD.
Also I tried to add APN but the device can't save it. (even I clicked SAVE, the new APN does not show up as an option to select).
I am stuck here so badly now. i have 3 LG v20 and plan to move somewhere but I'd like to use them. arghh.
I fought back with Sprint and got MSL code but.. not sure what I can do with it.
There are so many other people in the sprint community forum who are having the same issue as me).
any help/options are appreciated.
thank you.

Have you tried switching it from factory mode to test ? In the hidde menu, i dont remember were it is, but there is an apk that installs the hidden menu witch will allow you to switch between gsm and cdma mode. And i dont believe you need to sim unlock the v20, i dint have too.
