Hey I just received my HTC desire from Canada. I am trying to get it to work with At&t and it was supposed to be the Telus A8182 version. Right now it is not recognizing my sim card even though the device is supposedly unlocked. Because of this I cant access the APN settings to get it to work on AT&T network. I have noticed on the about phone settings that it says A8181 but the seller has told me that this could be due to the rom for the froyo update. I am new to these boards and android phone so any help would be appreciated. Thank You!!
Same Problem
I just got the Telus Desire as well and have the exact same problem. Here is what I have done so far and what i posted on another forum:
I just got an HTC Desire that was locked to Telus (Canadian Carrier). I have read that numerous people are using it on Rogers network. From the day I got it when I put my rogers sim card in (the right way) it said "No SIM card in phone" so I could not enter an unlock code. Thinking the SIM was defective went to Telus and tried one of their sim cards and it worked fine, then I went to Rogers thinking it was a problematic card. We tried 4 cards and none of them worked. I then went to Bell (another canadian carrier) and tried their sim card. It worked as well but said that the phone was locked. I purchased an unlock code from the internet which worked. Now the Bell sim card works as well becuase the phone is unlocked. I put my Rogers SIM back into it and it still sais "No SIM card in phone". I also tried a SIM from a european company and it did not work as well. This HTC Desire works on the same 3G 850/1900 GSM that Rogers uses.
I got my Telus Desire from Best Buy within the first week of release and unlocked it, works fine with my Fido SIM. Before unlocking it it did say "Network Locked".
Edit: Just checked with a deactivated Rogers SIM. Worked fine, notification bar said:
(No service)
Rogers
When I take the SIM from my AT&T One XL and try using it in an unlocked AT&T i747 (updated to stock, unrooted LH9) i'm thinking of buying it gets no data connection and only an occasional phone signal--and i'm in a good signal area.
Most of the time the i747 thinks there is no sim installed. For instance when I go into Settings->More Settings and try tapping on Mobile Networks the message 'Insert SIM card' is displayed.
I tried factory resetting the phone, no change.
I can swap my SIM into my wife's One XL and everything works fine... my wife's SIM works fine in my One XL. But neither my sim nor my wife's sim works in the i747.
I chatted with AT&T cust svc and they told me they have to register the IMEI of the new phone every time i want to swap SIMs which as far as I know is complete BS. Isn't the point of unlocked GSM phones easy SIM swapping?
I also tried shimming the SIM in the i747 with a sheet of paper in case it was loose. No change.
Any thoughts? Bad radio hardware? I'm there is something wrong with the i747 since two seemingly good SIMs won't work in it.
Might be a bad unlock aswell. Call att if your brave.

After many unsuccessful attempts i entered the secret code to check lock status (*#7465625#) and after it ran returned with:
'Connection problem or invalid MMI code'
But is that about lock status or that the running the code was in error?

I am on Rogers and can and always have been able to use my sim in any of my Rogers or unlocked devices. My wife on the other hand, is with Telus, and she cannot use her sim on any other device without registering the device first. There might be a self help online method if I recall. So it possible you have the same sort of deal is Telus?
Solved--exchanged phones at at&t service center, now have 4g on my s3 with same sim as i use with One X.
Hi everyone, I really need help
I dropped by a Verizon store to ask about M9's Verizon network locked, he told me that all their M9 is factory unlocked, and can use with different carrier than Verizon
So I went home and purchased a new Verizon M9 on eBay
The problem is when I inserted my MetroPCS sim card, it popped up "Non Verizon Sim - unknow carrier" and didn't work. I have already called Verizon and they also said that it is factory unlocked so it should have work.
Can anyone help me on that?

From what I know, you cannot use another carrier on a Verizon phone ( you can root and try to flash some carriers but that is pretty technical if your not familiar with it). Verizon phones are locked. I dont think metropcs frequency is compatible with Verizon. Verizon uses CDMA, metropcs is gsm
Sorry

I've used a couple Verizon devices on T-Mobile without issue. Sometimes you need to adjust the Apn settings. With the situation you have with Metro Pcs. Maybe you need to get another sim card and try that out. GSM does work on Verizon Devices without flashing anything. Do some Google research, I know someone has tried it. And I recall Tmobile is running the metro network now, so it should work.

You are going to need to be s-off to fix this......
For metro you have to go to a store and have them add the imei to their system
Since it's a Verizon phone, you will get an unknown SIM message when using another domestic SIM in the phone. It will work if the bands match, but the issue you'll likely have to add the APN settings for Metro.

I'm using VZW M9 with TMO without issues, so MetroPCS should work as well. You will have annoying "unknown SIM" icon on top of the screen, but other than that everything works fine. What does not work in your case? Please keep in mind, that VZW and TMO networks are different, so you might not have a signal from TMO network. If the signal is fine and you can place/receive calls and SMS messages, but there is no data connection and MMS messages do not work - you will need to store MetroPCS APN settings manually:

HI
Why cant I use an international sim in my Note 4. I have tried 5 different sims. Its like the phone isn't even trying to search for networks when I put them in.
If I'm not in the USA I cant activate the Phone can I?? I Think this maybe the problem. Its like the phone locks out the Gsm bands until its activated on the Verizon network. Ive tried a dummy Verizon sim but no dice.
Thanks
In advance
You have to call verizon before you travel to different country to unlock the phone. They will do it. I did the same. I traveled to India and used different sim and it worked. But you need to use apn settings from that carrier to make data work on note 4.

Hi even i have the same problem .Verizon should not lock as per their policy but they are doing so.Someone should put a case on them and sue them
The problem is when I was in the States I activated it on the Verizon Network, when I got home to Ireland phone worked fine with International sim.
Last week I did a Factory reset and its asking me to Activate on the Verizon network again and no sim is working, so I'm screwed I cant activate on the Verizon Network.
The thing I find funny is If you look at vn_mobiles root videos he is able to stick in his Vietnamese sim card after a Factory reset and have it work without having to Activate again on the Verizon Network. So am I missing something here?
I hope he can tell me if there is a work around for Activation because it seems to work for him.

vn_mobiles is a scammer.Any solutions? You gave verizon customer care email id? I am sure they will unlock GSM if we give our imei number since locking LTE phones is against their policy.
Unfortunatly I think the problem is it can't be unlocked unless registered on the Verizon network first with an active Verizon Sim (Which it was before factory reset). As Im not in the states any more I can't connect to the network so I can't activate, so its not really unlocked.
My phone never been activated on verizon and have formated the phone many times and gsm works fine with no issue except the lack of band 3 support....
Are good with DFS tool? If so pm me to test a few things that might get your phone working...
Got it sorted thanks guys.
Really strange one. I tried another Verizon sim. Tried activating and of course it wouldn't let me as I'm in Ireland. But as soon as I start sticking my local Sims in they just start working. Going to guard this little Verizon Sim with my life. Lol
They are unlocked but they might be needed to have vzw sim for few seconds. I was in Poland for 2 months and used my now retired note4. Was getting edge,3g,h+

Hello Sir
I actually bought a Samsung Note 4 910v from eBay which was being sold for parts which was not connecting any phone networks...
When I received the phone....it was on lollipop 5.0.1 and tried inserting a Orange Sim card from Mauritius network but It didn't work.
I flashed the note 4 to lollipop 5.1.1 and rooted it but still couldn't get the phone connected to a network...
I checked the phone IMei with Verizon ...it's clean
I read your post....please see image...
Could you help me with dsf tool or run a check of my phone plz...
Awaiting a positive reply from your side.
Hello,
I had my M8 replaced under warrenty and received a brand new M8. I am in Australia and use the Telstra network, and they provide network unlocked phones for plan customers, thus this phone isn't network locked.
When I first got it, it kept saying "Invalid Sim Card" on the lock screen for 2 days, and it went away by itself. The tech at the store said at that time they had significant network problems and we're resolved at the same time my phone was playing up. In those 2 days I also replaced the Sim Card and it made no difference.
Flash forward 4 weeks and I went overseas to Germany and the phone worked fine for a few days then again said Invalid Sim Card. No matter how many times I rebooted it I couldn't get it onto the network. Once I returned to Australia it worked fine.
I am now in South Africa and my Australian Telstra Sim Card was working fine but I needed a local number for data, so I purchased a Vodacom sim with data only and it worked straight away. My girlfriend also brought a Vodacom sim for her M10 (same Telstra plan as me) and hers is fine
My sim and phone ran on their networks fine for 12 hours and I wake up this morning and it's now saying "Invalid Sim Card" again. I've tried rebooting it several times with no luck.
Does anyone have any ideas?
I'm not convinced it's the Sim Card tray as it works fine on Australia, only when overseas. I don't know anything about the radio or baseband stuff but it's that related?? What can I check??
I used the IMEI24 website to confirm the phone was unlocked from the carrier, and entering *#*#4636#*#* doesn't show any info as it's not on the network.
Phone is currently unlocked, S-on, TWRP 3.0.2.0, rooted, Marshmallow.
I'm pretty angry as I have an ultra marathon in 2 days, and this phone was to connect my Garmin watch to the internet so my friends and family could track me, and most importantly my girlfriend could find me at the finish.
Any help would be greatly appreciated.
Thanks!

I doubt it has anything to do with radio baseband. GSM bands are pretty standard worldwide, and just about any "quad band" (850, 900, 1800, 1900) GSM phone should get you at least voice and EDGE data services. And all M8 versions support those GSM bands. Therefore, any M8 should get you at least GSM service, regardless of the radio baseband installed.
I wonder if the issue is the SIM modules themselves, and the "overseas" issue is a red herring? My thought is, that maybe the overseas SIMs you purchased don't quite fit as well as your local (Australian) SIM. One thing you can try, is put some Scotch tape on the SIM (on the side without the gold contacts) and see if that "fattens" up the SIM enough to make better contact. Be careful not to get tape stuck in SIM slot/tray. I've seen this trick work for some folks with the Invalid SIM error.
