Mine doesn't pick up bars until I go into the mobile data settings, select "available GSM networks" at the bottom, then search for my network and select it. It should pick up bars after you do that.
[Sprint HTC One (M7)] k000:
Thanks so much ! Will be travelling shortly and will come in handy !

In fact I just chatted with Sprint and they wanted me to take the phone to the store.

BTW - what should be the default preferred network when in US and wanting to stay regular / BAU mode?
[Sprint HTC One (M7)] adamlee011:
Is this different than Sprint unlocking it? I've had them unlock already. Can I not use the networks as you guys are? If that's the case can I use this method safely when I'm already unlocked? Thanks.

I have similarly issue. There is no available networks- when I try to find one, but when I put the sim card(t-mobile) I was asked to choose the carrier(only APN has been changed to T-Mobile). What I have noticed I can get sms and calls from other peoples, but I cannot call or send message. :) I have updated radio but it did not work. Do you know what is the problem, because I have try almost everything(I thing so :) )?

Thank You for all answer.

Hello everyone,

Brand new to posting but I have been reading a lot on this site, so just sim unlocked Sprint HTC one using the methods listed got my T-mobile sim to work, but as usual seeing that DATA isn't working, APNs are somehow resetting back to sprint APNs cinet.spcs, I reset the APNs to default and after I reboot it still shows Sprints APN programmed, this might be the issue with everyone's phone, maybe someone can figure out how to hardcode the APN to stick with T-mobile instead of resetting to sprint any help would be great.
[Sprint HTC One (M7)] elvisypi:
You have to save the settings after changing them. You shouldn't reset them to default, just change them to your operator configuration
[Sprint HTC One (M7)] mgrade01:
I have changed them and saved changes, created new APNs for T-Mob, and saved and once i restart the phone the APN setting change back to cinet.spcs, I need your expertise on this one because I cant figure out what I am doing wrong.

time to give up

I have read all 40 pages in this post as well as every other post that has to do with getting this phone working on T-mobile or ATT, and think it is best for all of us to come to the fact that an unlocked SPRINT HTC one will not work properly with T-mobile or ATT. It is something that we all must face, if not this will drive you crazy. Sell your Sprint HTC One and buy a Tmobile or ATT HTC one and be happy.

So to the hard working guys who have provided all the unlocks and Roms, I thank you for all your hard work.

[Sprint HTC One (M7)] billa:
Well, at least you've eliminated that possibility, though it happens quite often once a phone goes into collection they blacklist it months down the line.

I would try a brand new sim card too as in rare cases they go bad too. Then focus on the firmware and finally the hardware.

Edit:

I wanted to SIM unlock cause I was having slow data connection, so I wanted to try different methods to speed it up. However Ive cancelled on doing that, because I went to my carrier earlier today and asked them one last time why I am unable to watch YouTube or Netflix. Thank goodness I spoke with a person that knows a bit about phones. Long story short, the phones cdma settings were still on the phone so what he had me do was clear settings the involved my Msl code. It worked and now I don't need to venture in this SIM unlock.

Good luck to all who are having issues, and thanks for a great read OP.

Hello,

I am about to embark on doing the methods on the OP. I have a few questions though.

1. I don't want to be wasting money on different sims, I have quite a few choices, however I am not in the US. I have docomo Pacific, IT&E, and GTA and all of them offer SIM cards. Which do I choose?

2. Downgrading to the required RUU, means I have to reunlock my bootloader correct? I'm s-off atm is there an easy way with out going through htcdev all over again?

3. I guess that's it for now I will be coming back if any issues arise cause I believe I'm the only on Guam that has done "XDA" type stuff that I've seen/read/heard of, so this might be helpful.

ATT finally unlocked

What's up everyone? After searching numerous threads, flashing almost every rom made for the Sprint M7, flashing multiple ruu's, and flashing different basebands I've finally got everything working. I have working voice,mms,sms, and even GSM data icon. But there's still data issues whenever i leave home, i have to reconnect and sometimes it doesnt work but i'll still have voice and regular sms. And another problem i have is after downgrading back to 4.1.2 software version 1.29.651.10 my rear camera is really fuzzy and it just basically sucks but if i flash to any of the 4.3 firmwares the camera's excellent, but with the 4.3 upgrade and a flashed 1.00.20.3015 baseband and the HtcOMADM_SPCS, which ive figured is only to get into *#*#46363*#* settings i cannot connect to ATT under "Available GSM Networks" i'll click on ATT but then i'll get "Operation Not Allowed" so i guess ATT users cant be on 4.3 due to some Sprint restrictions somewhere or i just havent found a thread for this to work yet. but i"ve try the stock with goodies version and still had no luck. soo basically i have everything working to an extent but not a fully functional camera and a disconnecting data signal. If anyone knows a fix for the camera please let me know thanks. But i guess i can live with that plus i have Note 2 i'm using as well.. Im running everything stock, on hboot 1.44, s-off, unlocked bootloader, 4.1.2, and 1.00.20.3015 baseband. Right now im following "http://xdaforums.com/showthread.php?t=2647305" to try and fix the connection issues, but im stuck at getting my SPC code which is telling me that its "000000" but when entered it says its in corect and to try again in 10secs. If i can fix this issue i'll update the fellow ATT users, but from what im seeing and reading Tmobile sim users are getting better connections. My steps were flashed ruu to 1.29.651.10, booted the phone, finished activation steps, went to dialer *#*#4636#*#* went down and changed "WCDMA" to "GSM only", go to settings hit "Mobile data", check "Allow GSM Data", then scroll back up to Network Mode and change "CDMA Only" to "GSM/UMTS Only", then go down and hit "Available GSM networks", then "Search networks", then select "ATT". After that wait a min or so and you'll get signal and *"*"*BAM*"*" GSM data symbol!

Thanks to all the dev's and the xda community for making things possible and pushing to make things better and easier for everyones phones. I attacted some screen shots for everyone to see how my M7 is set up.

Hello every one i just read through everything all 43 pages lol. From what i see people are more successful with tmobile sim cards than att cards. I bought an att card from straight talk but i wasn't able to get it to work. Since its the only phone i have i switched it back to my old phone before i would tamper with it some more. I really would like to get this htc one on straight talk. I even went as far as to buy the tmobile chip but since i just ordered it it will take a couple days to get here. First has any one done this with a straight talk sim? The phone i got is stock. I unlocked boot loader rooted it sim unlocked it. But when i activated the sim card i got no signal at all. Also when i would go to available gsm networks it was grayed out on this att sim card. i am using the 1.00.20.0315 baseband version. So i dont know what was the issue. Any suggestions would be great.

AT&T type sim cards (including Straight Talk) normally block/grey out network selection on ANY phone not just the HTC One. One way to solve it on your phone is to load a custom rom like this http://xdaforums.com/showthread.php?t=2635051 which doesn't have roaming restrictions.

Seems it occurs frequently with or without making phone calls.

I followed the QPST/ CDMADev guide to try and fix the problem but i'm stuck there, I need to enable CDMA DIag and i know my msl but when i enter it i get a prompt stating that its processing and to wait a few seconds but i've waited 5-10mins and nothing thus i can't use the method.

As a conclusion, I have two questions regarding the unlocking.

1. Is it possible, after all, operation in GSM 900/1800?

Or only in 1900MHz?

2. Do I understand correctly that the phone only works with the stock firmware, because, baseband is different from the "normal" HTC One?

Update. I know this information is not new to mobile users who understand Band Frequency's. Though this is for you users who think your phone is not unlocked when it is. Believe me when i say this stop being frustrated trying to get your HTC ONE working on AT&T it aint going to happen in your area. Sorry but thats how Band Frequency's work. Stop trying different roms flashing radios its irrelevant in your location. Save the stress and free your mind and just pop in a T-Mobile sim card.

As you can see in you area you going to get more frequency bands with in 1700 MHz Thats for voice obviously IDk what the 3G UHF is i think thats for text messaging.. I am also learning frequency's my self so i started searching. Though if someone can use this Picture to make more mobile users to understand Band Frequency's have at it.

I am NEED of assistance if ANYONE can offer it.

Does this sim unlock also work for phones that are currently registered on Sprints network? Like the account is still active? I've got a Sprint HTC one I've performed the Sim Unlock attempting to use my T-Mobile sim, but it says "Emergency Calls Only," and "Searching for network/No Service" I've got a red X where the signal bars are. Of course No text, no voice and no data. I've gone into the *#*#4636#*#* service menu and changed the settings to WCDMA, but NO dice. Yes, I went to mobile settings, searched for service and nothing appears, just a blank screen! The phone does recognize my Sim card and even shows my cell number and IMEI, UICC as well. I've even attempted to change RUIM settings in DFSCDMA Tool but that does very little. I have changed the radio around about 5 different times, currently using 3.04.651.2 with NO fix.

You need the old radio for it to work. I drove myself nuts until last week, even I finally flashed the .0315 (iirc) original radio back. The other radios seem to ignore any US GSM providers, but do work abroad. I had my Sprint phone on T-mobile. It does work!
