Now is it an HTC One S or the One X for AT&T. You never answer the question above, does it say Tmobile on the front of the handset?

I did answer! But yeah, it has T-Mobile up top and it's the One S.

that happend to me in my tmobile sensation. i bought a T-mob htc sensation 4g and unlocked it to use it in telcel mexico, after some months i decided to change company and put it a movistar simcard, but it didnt read it; the phone was re-locked to telcel in a strange way (i dont know how)

the only thing i did, was to re-use the unlock method for the htc sensation and everything was fine again...

so, try to use the unlock method for the htc one S and check if that helps you (:

I agree.
Networks have changed a lot in the last few years. A 5-yo sim card is likely to be the cause of the problem.
If the network is just sim-locked you would get an 'Insert unlock code' message [or similar].

Sorry i missed that. I would get a new sim like everyone has suggested.

Update:

Alas, getting a MircoSim did not work. Perhaps it is blacklisted (I tried asking the guy there and he said he couldn't check, ugh). So, For now, I'm going to try to get a refund (guy said he was willing to) or try to trade it on Craigslist for something that will work. Unless someone can send over a quick guide on how to unlock the SIM reader. I tried the one that is posted and I never got the options that should have popped up.

That suck ballz. Hack sim should work but if its on blacklist there no way it can work on T-Mobile if your unlock it.

Try this, on dialer hit
*#*#4636#*#*
Choose "Phone information"
Scroll down to Radio, see if it's On or Off.
Maybe pretty with it, turn it off turn it on see if it give you anything

When my One S was blacklisted, it gave me the same error.

You can call or chat online with T-Mobile support, and they'll tell you if it's blacklisted.

Will check tomorrow whether it's truly been blacklisted or not. And I had actually tried the radio thing earlier I was very hopeful that would work.
