PLEASE HELP!!!! Unlocked Diamond not reading Network 3 Sim card

Hi guys,
This is my very first post so please be patient with me.
I just received my HTC TD purchased through Ebay. It is a model P3720 with the Telstra NextG branding on box and phone cover. It was advertised as unlocked yet it does not read my 3 sim card. It comes up as sim card missing.
How do I resolve this issue? Can someone help? Im excited about receiving this phone today and simply dying to play with it, so if any of you can give me some advice I would greatly appreciate it.
Thanks

Step by Step...
I'd say first get a Telstra SIM and try that in the phone, this will tell you if the phone is working correctly... Then get a SIM from another network (not 3) and try it with that SIM, if the phone recognises the SIM it is unlocked, if not it isn't and you can get it unlocked by looking at the sticky Diamond unlocking thread on this forum...
If it works with the second SIM but does not work with the 3 SIM take the 3 SIM out wipe it off blow onto the contacts in the phone and try it again, if it still does not work try the 3 SIM in a 3 branded phone to see if it works. If it does and the Diamond is unlocked you might have to phone 3 customer services for advice - don't expect much though as they will probably say they don't support phones which are not branded as 3 phones.
The alternative is to search around here for some more help.
Hope the above has been helpful.

[Q] I can't get T-mobile to work..

I'm giving my incredible 2 to my friend who has T-mobile and i flashed cm9 global because it's a gsm default rom and it won't connect to any network i tried putting in the T-mobile apns and they won't show up, any help would be greatly appreciated.

Did you have the sim unlocked with Verizon before you left their service?

I still have there service i just upgraded phones and i gave my inc2 to one of my friends and no i haven't got it unlocked..

You'll need to call global support and get the unlock code for your sim.

Aye, but I'm not sure Verizon's policy on unlocking the SIM on an unactivated phone. You may have to activate the Inc2 again before they will unlock it.
Maybe someone else knows the policy more and can chime in...

They will unlock one phone per year, shouldn't have to activate it. Please let me know if you can get hspa+ on it once you've done it... For the life of me, I cant get mine to work.

I'm having a similar problem with an Incredible 2 for a friend. Flashed CM9. He was unlocked already, so he can get phone, but not data. I'll write up a post about it, but I'm still interested in this thread.

My girlfriend has my old inc2 and she is with tmobile. I just paid one of those sites 10$ for a unlock code and entered in tmobile's apn's and it has data. But with the inc2 being cdma radios and tmobile uses gsm it will only get edge "2g" connection.

I recently unlocked 2 Inc2s in anticipation of moving them to t-mobile. They were both out of contract but still activated, and my first call to global support ended with the woman telling me, bluntly, that Verizon doesn't unlock phones period. I had been telling her that we intended to give them to family members who weren't on Verizon after we upgrade to new phones. No dice.
Not being one to give up, I waited a few minutes, called back and said that we would be traveling to Europe and wanted to be able to use our phones on a local carrier while we were there. No problem, I was given the 2 unlock codes immediately.
So if/when you call, that's probably the best story to use. As soon as they hear that the phones will be going to another carrier, they have no incentive to help.

Ok i finally got the unlock code for it and i was running viper 1.20 and it told me to use the code so i put it in and it said invalid code so i returned to the stock rom and now i don't know what to do, like i don't know where to put the code in at..

Nevermind guys i finally got it unlocked and T-mobile is working fine on it

Finally I brick my E973,, :(

Couple days ago my beloved Bell E973 wont reay sim card.
Here is what happed. the original from bell, but I bought a unlocked code to use my Rogers sim. It's working perfect for 2 or 3 weeks. I love the screen. personal I like it bettter than S3.
I did not root or unlock the bootloader and one day when I put sim card in, it just said NO SIM. I tried with bell sim. same
So I rooted and tried all kind of ROMs, even F180S. that's fun. but still wont read sim.
If anyone buy it as a parts or want to fix it. let me know. I am in Toronto

You tried to re-unlock it ?
Also, if you flashed korean firmware, your radio will mostly be gone.

no really to re unlocked it, since I tried my friends Bell sim. doesnt work

i saw your post on kijiji lmfao !! we live around each other lmao!!

Did you put it in the proper way?
I made the mistake of putting a sim in the wrong way once on my BB and even took it to a Rogers store and then felt like an idiot after the guy pointed out what I did.

It's still under manufacturer warranty

Two things about your phone:
I may be interested in it for parts, depending on price of course. Mine has a dead spot in the digitizer, and as I bought it second hand, LG won't warranty it for me. I'd not want to spend more than the price of a screen/digitizer assembly, so it might be worth more to someone else.
Have you tried a different sim in it? If the phone is unlocked, try a friend's sim card, maybe your sim just died. Edit: missed your reply about trying your friend's bell sim

Have you tried a hard reset?
Have you tried reinstalling the original rom, using the original KDZ file and the "unbrick" method?

Can you browse internet, play store, or use any program with data connection via wifi?
- first, it might be the unlock procedure did it. I had 2 out 5 devices ran into this scenario after doing a factory unlock.
- second, but unlikely and super scarce situations, Bell might have locked up your device's IMEI that caused it. I got one relative that the carrier locked up his phone after doing a factory unlock.

My Rogers E971 stopped recognizing SIM cards yesterday. It is unlocked/rooted. Hoping I can reroot/lock bootloader and send in for warranty service. Still trying to figure it all out.

same problem

I am hoping to set mine back to stock and send in for warranty servicing.

Optimus G sim card inserted or removed all the variations of the device automatically restarts.
Did you notice this situation?
Inhabitants of this problem, removing or inserting the sim card would not open the device?

Woo911, you have used wrong title for your thread thus eliminating people who might know a solution to your problem to ignore the thread, inability to read the sim doesn't mean your device is bricked.

When I first got the phone it would reboot when I inserted and removed SIM cards. It has since stopped doing this.

Just an update. I couldn't figure out how to unroot and relock my bootloader. I ended up sending it off to LG for warranty servicing via my carrier and they fixed it free of charge.

[Q] data doesnt work on unlocked galaxy s3

Hi everyone,
I have, hopefully, a simple problem. I recently upgraded to a galaxy s4 from the s3. the s3 is a year old as my corporate contract allows me to upgrade my phone every year. so I am with bell, and my wife is with telus. she wanted my s3 since she has the iphone 4 and is sick of it. I updated the software on the s3 about 3 weeks ago so some of the threads on here wouldn't work for unlocking it. I went to the cell unlocker website and paid for a code. I still have the email they sent with all the codes, unlock, freeze etc, and it worked. I put her sim card in and could text and call out. the phone says telus where it said bell before. however the data will not work. Wi-Fi does but mobile data will not. we went to a telus store, they upgraded her sim card but to no avail. I tried searching for threads here but didn't come up with something like this. the phone is stock, no mods or anything, I even reset it back to factory settings, sim still works just no mobile data. I tried to get bell to unlock it before but they said they couldn't cuz it was tied to a contract.
I hope someone has seen this before and can help because i'm at a loss.
thanks for any ideas

Have you looked into the APN settings? I have them around here somewhere. I can locate them and forward them to you if you'd like. You can also find them right on the Telus website. I'm thinking that's a good place to start.

that would be awesome, thanks. I know the rep for the telus kiosk at Devonshire mall went in to look at a few things, but he wasn't sure and google what was happening but he said it was all at&t stuff, then gave me back my phone. but yeah I would appreciate the info. not sure if my email shows or not but it is [email protected]. I will try that out and post back as to what is happening.

Help flashing t-mobile firmware to SM-G9600 (international unlocked)

Hi all,
I recently purchased a galaxy s9, model SM-G9600. I have never flashed a phone before so I'm quite new to this all. The problem with this phone is that it has no wifi-calling option in the settings. I currently have my t-mobile sim card in it. I've tried looking all over for an outside solution to this or if it is possible to just flash the proper t-mobile firmware to be able to get the wifi-calling option in the phone. I cannot seem to find a concrete answer/directions as to how to solve this. I was wondering if anyone could help me find a concrete answer and/or point me in the right direction.
Thank you in advance!

Hiya bud. Well the answer I'm gonna give is one you probably won't enjoy much, but no one else responded sadly.
I'm pretty sure that the wifi calling option will only work if you're on the correct calling network (I believe only tmobile branded for that software ).
I could be wrong though and the calling may work for other carriera, but I just thought I'd warm though ahead of time on your quest for the holy grail in case anyways.. If things work out better for you, then definitely let us know!
Cheers bud!!

Did you get it to work?

I have the same model and am on the t-mobile network. Did you flash your phone with the t-mobile firmware?? If so, did it work??
Thanks!
