[Q] Won't connect to AT&T - HD2 General

I recently got an HD2. According to the seller it is unlocked, but With my AT&T SIM card in it, it won't connect to the network. Originally it had WM6.5 but I just installed ICS and it does the same thing. Help?

I think it possibly my SIM card was locked to my previous phone (I don't think I would have done that though). It wouldn't let me into the SIM lock info in the settings and now it is PUK-locked. I will try to get the PUK code from AT&T.
EDIT:
I just got the PUK code and unlocked the SIM. AT&T wouldn't show up in the available networks before; now it does. It still won't connect though. It cannot get past "Registering on AT&T..."

How do I know if my HTC is locked (simlocked) or not without another Sim?

Hi,
I've bought a HTC Magic from Rogers. From the internet, it seems that some ppl were saying Rogers did not lock any smartphone, but most said it does.
I've tested with my wife's Fido Pay-As-You-Go SIM card, it seems to work. So either my phone is unlocked or Rogers and that Fido prepaid card are sharing the same lock-code.
Anyhow, without any other tools, how can I tell/test if my phone is simlocked or not?
Thanks,
Gary
The Rogers phones are locked. Fido, PetroCan Mobility and Speak Out are all virtual network operators that run on the Rogers network so their SIM's will work in a locked Rogers phone.
You need a non-Rogers SIM (like from a new Bell or Telus phone) or a US or European SIM. As soon as you pop it in it will tell you your locked and will ask you for the unlock code.
Phone won't run home screen but instead will ask for "unlock code".
And unless you give it you can't use the phone for anything (you can't even check any menu, settings or anything).

[q] please help-atrix unlock issues

I am not sure what happened. I have an ATT branded atrix. I purchased an unlock code from someone on ebay, and the code was incorrect. I entered the code several times and I believe i have carrier locked the phone. Now even when i stick my att sim card in it brings up the "enter network unlock pin screen." I can hit dismiss and get into the phone but I cannot get service even with my att sim card in the phone. So as of right now my phone is not unlocked and is unable to be used with any sim card. Please help as i need the phone. any advice will be helpfull.​

[Q] SIM not valid - Enter SIM network unlock PIN

I have tried every code mentioned, in here, that was successful for others but not for me.
I started by buying my Galaxy S4, out right, at Walmart for use on Family Mobile. Poor signal everywhere except in my house. The phone has T-Mobile support as far as towers go. After about three weeks I had my phone number transferred to Straight Talk and they sent a SIM card for use with AT&T support. The phone was purchased as an unlocked phone, I did all the codes in this forum to check and sure enough, it is supposed to be unlocked, BUT, every SIM card I get from Straight Talk gives me "INVALID SIM CARD" when I boot up the phone then a black screen comes on with a subdued color message saying, "Sim network unlock PIN" and all the help from Family Mobile, T-Mobile, Straight Talk, Walmart and AT&T, have not helped my situation. I can't write a new APN and store it because I have an invalid SIM card. I have tried the service mode and did everything mention in these forums but no luck so far.
I really like the device(my NOT-Phone) but it does not function as a phone. Can anyone help with this one?

No warranty in Walmart?!
If it connects to T-Mobile towers out of the box, can you borrow a T-Mobile SIM from soneone and go through the SIM unlock procedure? I'd do that just to make sure it's SIM unlocked. Then try Straight Talk with whatever APNs they use. Do this on stock and once you can confirm you get that far and it's working then go crazy. Good luck.

If I put the original, 1st SIM (Family Mobile) that I bought, back in, I do not get the Unlock Sim code message but I also do not have service because I already had the number ported. I've been that route. I tried the APN routine but it won't save because I don't have service with that SIM card. I go into the unlock routine through the service mode and it says it's already unlocked. Any Sim card from Straight Talk gives me Invalid SIM.
I'm going to return it to Walmart and try another phone.

Unregistered SIM problem

But a S5(SM-G900W8) second hand that was described as unlocked on Jan 5. From the kijiji ad looks like they were using Telus. Put my Fido SIM and and off to the races. Except it wouldn't update. Flashed with ODIN to Telus firmware from SAMMOBILE. Still working fine.
Until Jan 14th. It just stopped working. Says unregistered SIM. Tried that sim in a G3 and it works no problem. Tried working SIM from G3 in S5 and no go. Took it to Fido store. No help but they did give a new sim. Can read SIM information using app.
Not blacklisted with Fido/Telus/Bell/Virgin/Koodo. Called them all. All of those providers have no information on phone when searching by IMEI.
There is a Bell TV app on phone so I thought maybe it was originally Bell and went to a store to see if they had any info. No info but girl in store tried her bell sim and it worked. I assumed that somehow in the firmware/software upgrade process it had lost it's unlock and must be back locked to bell. Tried to unlock it from Bell but it fails says IMEI not in database(from internet unlocking service).
Still thinking it might be locked called all providers mentioned above to see if they know anything. Nothing. Sidenote when I put my Fido sim in it just says unregistered SIM. Does not pop up for an unlock code or anything.
Tried a friends Rogers SIM. Unregistered SIM. Drove to Telus store to try a SIM. It worked but no service because it was not tied to an account(but did pull Telus APN's from connecting).
So it appears as though Bell/Telus SIM's work. But Fido/Rogers say unregistered SIM.
Called Fido again and they had me go through all the manual APN setup etc. Then something about sending a new signal to phone from Tower to reset network settings. Didn't work. Fido has no answer for me at all. But yet it did work on Fido for 9ish days.
I'm stumped.
Bueller?
Did you ever fix this issue or find the cause of it?

[Q] AT&T S5 -- Sim question

Thanks in advance for your time.
I consider myself somewhat savvy. I have searched all over for an answer before asking:
I bought a SM-G870A and I have tried putting an H2O SIM card with no unlock screen. I tried two other SIMS with no unlock screen. I assumed it was unlocked.
I tried selling this phone to a guy who was going to use it in Mexico and told him it was not SIM locked. He tells me that when he puts his SIM card in it asks for an unlock code.
I am lost as to why it would suddenly ask him for an unlock code but all my SIMS did not. I have not been able to see him try in person yet.
Why would I be able to put SIMS in the phone and not get asked for an unlock code. I thought that meant it was unlocked?
Thanks for the help!
I just went through this "sorta" thing when I unlocked my t-mobile s5. I took out my t-mobile sim and put in a metropcs pcs sim and got no unlock screen upon reboot. I put in a cricket wireless sim and upon reboot I got the unlock screen, which I quickly put in my unlock code.
I'm assuming since metropcs is owned by t-mobile, that is why it didn't ask for an unlock code.
Is h20 owned by at&t, if so, that could be why the phone didn't ask for an unlock code when you put in the h20 sim

Thanks for the feedback. There could be something like that going on.
h20 uses the ATT network.
I tried a Simple Mobile (T-mobile) and no unlock code prompt
I tried a US Cellular LTE card -- would not connect to network -- no unlock code prompt
I tried a Verizon LTE card -- Same as US Cellular
I am stumped as to why this would happen. I would think a locked phone would not accept those cards without an unlock code prompt.
