[Q] AT&T Sim Lock

Hello,
I have recently just got back to the U.S from europe and have been given a blackberry phone with an AT&T sim card by my father. And have a HTC Topaz running ENERGY ROM but when i put the sim card from the Blackberry into the Topaz it doesn't work. It says:
Sim Lock
"network is locked, please input unlock code"
I used to have a pay as you go AT&T card last year and it worked fine but this one doesn't seem to work on my Topaz.
Any ideas on how to make it work?
I appreciate all information and help handed!
Thank-you in advance!

[Q] Phone network not working

Hey there,
Long story short, I sent a G1 for repair about 6 months ago because the touchscreen was busted, I finally got it back, decided to update the radios and hboot, before testing if the phone network worked in the first place.
If I go to Fastboot, the phone says
Dream PVT 32B SHIP S-ON
Hboot-1.33.0013d (DREA100000)
CPLD-4
Radio-2.22.28.25
Oct 21, 2009, 22:33:27.
Problem is that I tried a pair of Gingerbread Roms and can't get the phone to connect to the network. My G1 is unlocked, and I'm on Telcel (AT&T bands, not T-Mo bands), and all I get is a popup saying "Welcome to Telcel International Roaming", but it won't connect to any networks, roaming or not.
I've tried switching back to the 2.22.23 and 2.22.27 radios with no luck, the only thing I haven't tried is switching to the old hboot, because I'm afraid that coming from a newer hboot, it might brick the phone.
I'd appreciate any advice on what to do, I'd really like to have the G1 doing phone calls again.
Thanks.
Edit:
I'm currently on hboot 1.33.0013d, radio 2.22.23, Cyanogenmod 6.1.0 and still no phone signal.
I'm thinking on reverting the phone back to Android 1.0, flashing the original DREAMING.nbh on fastboot and the Andorid 1.0 rom. Will this undo all the hboot and radio changes I've done? Is it safe, considering the fact that I'm on hboot 1.33.0013d and radio 2.22.28?
Thanks.

i think your sim card is fried, it happened to me as well, just randomly out the blue one day i could connect to service provider, as far as the phone knew i had no sim so i went to tmobile store and got a new one for free and everything was fine again

I'm pretty sure it's not the sim card, I tested it on another phone and it still works.
At this point, I can only blame the guy that "fixed" my phone, who not only managed to not fix what I asked him to fix, he also broke the phone antenna, apparently.

hmm... wow that sucks man im sorry to hear that, have you tried different roms to see if the issue still exists?

[Q] Why isn’t sim card being recognized?

Hey all, I’m having problems with my sim card not working, my Captivate doesn’t recognize it at all. I got this captivate to hold on to from my older brother who is currently serving overseas (not possible for him to use phone) a few months ago. When I got it, I rooted it, sim unlocked it (I have t-mobile), and got to flash roms and have fun with it thanks to you good folks on these forums.
About 2 weeks ago, the speaker was issues that really bothered me(had to keep tapping it in to get It to work) so I decided to send it over to Samsung to fix. The phone was still under warranty, so it cost nothing to fix fortunately. I just got it back yesterday, and since then my t-mobile sim card would not work. I rooted, sim unlocked, and flashed many different roms and still not working. Its as if the phone thinks there is no sim card at all (“No SIM Card Emergency Calls Only”). I also tried this app called Samservmode, and enabled all bands (GSM/WCDMA) to see if it would work; it didn’t.
I was ready to call Samsung again, but when I went over to my friend’s house and tried his att sim card; it worked perfectly and I was able to send texts and make calls. So something must be wrong with my sim card, it works perfectly on my g1 though (my backup phone that was used while Captivate was away). I was able to use the same t-mobile sim for a few months in a row before I sent it to Samsung, isn’t this possible for me to do it again? Any advice on doing so would be much appreciated; thanks.
P.S. My t-mobile sim card is prepaid if that matters, so I don’t use 3g or edge or any data networks.
Also my current setup (if it even helps, I've been flashing between froyo and ginger nonstop trying to fix this issue)
Firmware: 2.2
Baseband: I897UCKB1
Kernel: 2.6.32.9
Phone number and network is unknown
Mobile network type: HSDPA
Service state: Out of service
Roaming: Not roaming
Mobile network state: Disconnected
Everything else works pretty fine on this phone (wifi, bluetooth, etc.)

UPDATE: I went back to my friend's place and with his att sim card in, I tried adding a t-mobile APN based on
http://forum.xda-developers.com/showthread.php?t=744535
Unfortunately this did not resolve the issue. I did this with his att sim card because when there is no sim (or in my case, my tmobile sim) in the phone, you can't access mobile networks in settings.
I am also currently on stock I897UCKH3

UPDATE 2: So I just tried my other friends t-mobile sim card (that is on a plan) and the captivate had service; was able to make calls and text. My prepaid sim card seems to be the culprit here. I don't understand because as I tested my friends sim card on the captivate, I also put my sim card in his iphone 3gs (unlocked) and it worked fine there. Is the captivate on strike against my sim card or something? I'm going to try calling t-mobile tomorrow (doubt they'll help since the captivate isn't their phone) and see if anything can be done. In the meantime if you guys have any advice, I'm all ears.

UPDATE 3 (This is getting kind of annoying): I just got off the phone with both Samsung and T-mobile and both of them don't know what to think. I'm beginning to think this is a special case and this problem only occurred to a very few amount of people. If anyone can help with suggestions I would be very grateful. I'm thinking about going to a t-mobile store today to see what they think, maybe seeing the issue in person would help in their perspective.

Doubt anyone is going to answer or even post, but here goes:
BUMP
I also went back to stock and followed this guide:

with no success.

You try getting a new sim card?
Sent from my I897 using xda premium

Does T-Mobile have any policy of replacing prepaid sim cards? If so, that sounds like your best option. Also, Samsung might have been angry at you cheating their system, and purposefully disabled your sim card. Make sure you take out your sim before sending it back for repair.

Thanks for the reply guys, much appreciated. I decided to just live with it and keep the captivate as a galaxy s wifi if you will for media purposes only like an ipod touch. My g1 will be a phone. Once the nexus prime comes out I will start up a contract and finally experience 4g speeds and w/e else I can get with a contract thats not available on prepaid.
Also I did not send Samsung the phone with the sim card in, idk how they must've known to block it. Thanks again.

[Q] Can connect to 3G but no calls or messages can be made or received.

Hi,
Recently I received an M7 my girlfriend found on the street. It was from Vodafone and I had a GiffGaff SIM. This is what I did:
I unlocked the bootloader
Rooted
Installed Android Revolution HD v91.x
I did this while on holiday in Spain. Inserted my SIM and it worked. Using roaming I was able to connect to 3G, do and receive calls. Last Friday I came back to UK and once landed I started my HTC and I got 3G connection but no signal bars at all, and I couldn't call or receive calls. Curious is that I had to create the APN manually.
What could be the cause? I've tried with various different SIM cards from different carriers, but with none I get signal. Could it be that Vodafone has blocked the IMEI?
I've tried doing S-OFF to change the CID but I'm not able. My phone info:
Code:
M7_UL PVT SHIP S-ON RH
HBOOT-1.56.0000
RADIO-4A.26.3263.05
OpenDSP-v32.120.274.0909
OS-4.19.161.11
eMMC-boot 2048MB
Any suggestion on what I could do ir try?
I wanted to get S-OFF to change the CID, or even the IMEI.
Any idea why I'm getting 3G but no signal and can't make or receive calls?
Thank you very much.
Any help is appreciated.

If the the device had been reported lost or stolen its very possible that the IMEI has been blacklisted.
You could try flashing it with an RUU, but if it is blacklisted that will make little difference. But if it's a software problem it should resolve it. :good:

Hi Danny,
Thanks for your answer! I've used Check Mend to see if the IMEI is blocked/blacklisted or not and yes, it is. Basically I can't do lot with the phone. I can use it as MP3 and "game console" while using my old Iphone for calls... I will probably end up buying a new phone, but I hate that they've moved the home and back buttons on to the actual screen :crying:
What I could do is call Vodafone and tell them that I found my phone and if they can unblock it. But they'll probably need a proof of purchase so I don't think it'll work.
Sad.
Thanks anyway!

AT&T HTC One unable to detect Sim Card. Doesn't even notify sim card missing.

my At&T Htc one m7 is unable to detect the sim card. It doesn't even show an error in the notification window almost all of the time, sometimes when i get the notification error (no sim card) i insert the sim again and it works. I tried the tape fix but it didn't work. Tried bending the tray a little that didn't work either. Tried using a nano-sim with a micro-sim adapter but that also doesn't work. Even when the sim card is inside the option to search networks is greyed out. I'm in India bought it on eBay in Dec'14. The HTC service guys are saying they cannot repair AT&T at all. What can be the issue ? Is the sim card reader faulty ?
I'm running Lollipop 5.02 stock with S-OFF.
Any help is appreciated.
Thanks.

I would strongly recommend not bending the tray, adding tape or using sim card adapters. All these things can make the situation worst, many members got their sim tray stuck inside the phone because of that.
Backup your files and try a factory reset first
If the phone isn't stock, you should flash back the stock rom
Also try with a new sim card
If nothing works its maybe an hardware damage and you'll need to send the phone for repair

I'm fully on stock, tried factory reset, tried with different sim cards (with a brand new one too) but nothing works. Problem is I don't know where to get the set repaired in India as the HTC service center refused to service it saying they won't get the parts for AT&T. Can sim reader be a problem ?

Not the first time I see this. Its a cheap excuse because they don't care/want to provide support for devices that were not purchased locally. I can't believe it's impossible for a big company like HTC to get the parts from the USA center or even directly from the manufacturer from Taiwan. Anyway it might not worth it depending the cost of repair, a brand new M7 cost around 200$

Maybe it could also be anything else like the radio or the motherboard, its hard to tell.

Got it rectified .. it was an issue with the imei .. the number just sometimes went blank because of which all this kept happening .. wrote the imei again and it's working fine since a day
Thanks ..

Sorry for the late reply man, nothing got rectified, I even got the network IC changed. After a day it became the same again. Sold the set as the HTC guys in Delhi said the motherboard needs to be replaced.
Were you able to solve the problem ?
