While I'm waiting for my new 4g sim from att in using my 5yr old sim cut with my trusty kitchen knife..
It worked fine for voice but only registered the 4g apn which did not work (always thought the sim was simply a dumb number storage) ... So i manually typed the 3g cingular apn that registers on my old phone with the same Sim.
It worked. I do get data. But the data icon show "E" next to it...
Anyway to get gprs?

Im pretty sure its your networks APN. its different from postpaid. just like what we have here in manila. globe tel uses internet.globe.com.ph for postpaid and http.globe.com.ph for prepaid. commonly cm7 builds with auto APN detects my sim as a postpaid vut its not so I have to edit them after flash. happens also to my other phones.

"I called ATT..." GSM...
Have you checked the APN settings. Mine was unlocked when I got it and it just worked. When I downgraded though it wouldn't connect I went in and checked the APN settings and it had lost Tmobile's APN settings. I just re added them and reset and it worked. Hope this help

T-Mobile APN updated automatically. i said that in my original post. i believe my AHD is on ICS 4.0.4 is there an update above this that may be causing the issue? like i said, it is unlocked with ATT Sim Lock code but will not receive service except for Emergency Calls only. when the T-Mobile sim is inserted the network bars disappear but the APN updates
It looks like the phone is successfully unlocked.
You can double check the APN settings against the ones recommended by T-Mobile or even create a custom APN with these settings.
Is the SIM card activated? Does it get signal on another phone? If you use the Phone Info app or any other app that lets you in the hidden testing menu, can you check if you get signal if you change the preferred network type to GSM only or to WCDMA only? WARNING: Do not change the radio band.
FYI I'm on T-Mobile with ICS 4.0.4 and I've got signal in multiple places in the US and roaming overseas.

HI, GUYS,
so I just got this unlocked HTC ONE from HTC shop
and I am currently using T-mobile, but I have issues with 3g
i used to have HTC desire z and 3g works fine,
and I went to shop, change my sim card to micro sim card so that i can use it in HTC ONE
BUT, everything works perfect excepted 3g
mobile network only can find T-mobile 2g network and at&t 2g/3g/4g network when i search the network operators
and i am not going to do roaming.
I tried to change VPN but it doesn't work
I also tried tweakker, but for some reason, it kept saying my wifi didn't connect to internet but it did connect to internet..
so could somebody help me
i didn't root my phone yet, and the rom is official rom
Software number 1.29.1540.16
thanks
You're not going to like this answer, but the unlocked HTC one lacks the 1700 band needed for T-Mobile 3G. The good news is T-Mobile is in the process of reforming their network so your phone should get 3G by quarter 3 2013. Until then you could try an AT&T mvno or return it and buy one from T-Mobile that has the required bands.

which one to use at any particular time?
Just voice on Verizon - no SIM.

Looks like there are 100 other people who are just like me - don't know.
It looks like this would be possible with just a switch of APN's and checking a choice under "networks" or possibly it would auto choose the APN based on networks choice. But in practical application would it work?
I know i have switched b/w AT&T, T-Mobile, and VZW and it would recognize the network. Only network that wouldn't work for me was Sprint.
Verizon LTE phones require a Verizon SIM to work with both its CDMA network and its LTE network. If a Verizon SIM is not present in one of these devices, it won't work with either Verizon's CDMA network or its LTE network.

Yes, my question though is, for voice only on Verizon - without SIM just CDMA activation - Can a person have both and switch easily between them by activating the 3g data - voice via phone identification no SIM required with Verizon (pageplus) and a SIM for at&t (straighttalk or redpocket).

Ah, interesting. I hadn't thought about using a CDMA MVNO on Verizon. I know that if you are just using Verizon, CDMA activation without SIM won't work because Verizon is using the SIM to authenticate to its CDMA network on LTE-enabled phones. But for Page Plus, you may be able to manually program the CDMA activation without using a SIM? Have you manually programmed CDMA phones to work on Page Plus in the past, and if so, how does it work?

Yes, I have a Moto-G activated on pageplus. I called them up, gave the ph ID then called a Verizon activation number. Worked well.
My problem is I am on the edge where Verizon works a bit better (have to walk outside and find a reception area) at my home with AT&T not picking up except occasionally. If I had the cheap pageplus plan for Verizon (not LTE) and Redpocket or straighttalk activated on AT&T it would give me a bit of flexibility if I could do it on one phone.
I just don't know if it will work. Perhaps the Nexus 6 being a LTE device won't activate on pageplus as a 3g device.
I may just activate an AT&T MVNO SIM on data and just use hangouts and hangouts dialer. Use wi-fi at home and data SIM when about. Redpocket has a T-mobile 1 GB plan for $10/month; haven't yet tried Tmobile reception. I live in a cellular black hole.
As crazy as it sounds, I was experimenting with roaming ability and did a *228 and #2 on my phone with Verizon. Since I did that LTE went away all I see now is 3G
Did not change the APN only have one and set on LTE for network....
Could I have messed up my PRL but I thought the PRL is now on the SIM?
whats a *228 and a #2???
*228 is NOT supposed to be used with a 4G SIM Card, you may have broke your SIM.
This hasn't worked on any lte device, why do people keep trying it? You need a new sim.

Sounds like my man is right has broken the sim even putting it in iPhone still comes up 3g when it did LTE was the same phone I used to get a nano sim. Off to Verizon see if I can get a new sim.

I knew this was a bonehead move thinking I could get volte work after updating radio. Cause not listening to my inner man!
Similar thing happened to me as well, after I updated to 5.1. Worked good for a day then all of a sudden I couldn't receive calls no more. I could make calls, text and use data. I called Verizon and they reset some things and the service completely went away, then we got disconnected. After calling back the rep said my sim got broken somehow and told me to go the Verizon store and get a new one. i think the first rep disabled something and couldnt get it back on.
New sim was activated in another phone then put into the Nexus 6 and all was good. Funny thing is I didn't do the *228 thing and my LTE was still showing when I stopped receiveing calls.
