I haven't been able to find any solid information on SIM unlocking this phone, so I'm asking here. Back on Verizon, unlocking a global phone didn't seem to help much, as it still didnt work on other carriers (such as when travelling to India). Will the HTC One when SIM unlocked work?

The HTC One is a GSM-based phone. It will work on any GSM-based network, regarding calls/text/data(up to HSPA+). Not sure about LTE because of the way the frequency/bands work.

Verizon was CDMA which had limited availability in foreign countries. HTC One has a sim card slot (even the Sprint version, which is CDMA, should have a slot). Once you sim unlock, it should be compatible with most major countries since most countries use GSM - as long as the frequency bands are the same.
You can look up the frequency bands phone supports in the htc one's specs.

Hi,
I have bough one HTC ThunderBolt Verizon in America,
I tried to insert my sim card without success, can I unlock it? or is it impossible at this moment?

this post was a fail
the sim card in the phone is meant only for the 4g. the phone is only cdma, not gsm. you can't put the card in there and assume it's going to work.
The Thunderbolt isn't a GSM phone. It uses a sim card only on Verzion for 4G purposes. I doubt it would be useful to do any unlocks on it.
I think this thread is a fail.
I'm nearly certain that as of right now, the Thunderbolt will work on no other carrier but Verizon. MetroPCS flashing isn't really possible since the phone uses some of the new technology to activate itself, the old activation code doesn't work, I believe. And the voice technology is still CDMA, so even if the Verizon bands match up to a Euro/Canada carrier in the future, you'll have to wait for LTE to carry voice, which could still be quite some time.
My sim is 3g, and my operator are gsm/umts but 3G not 4G.
I cannot to use it? If I understand well it works only with operator 4G?
Thanks a lot
Z.
There is a solution to put it on metro and cricket.
Wow, how did you even find xda?

I am always confused between CDMA and GSM...
Why a 4 band phone ,Evo 3d will not work in Europe?
BTW I am searching to buy one at Ebay. the search shows only Spirit branded phones. do they work in Europe (GSM)?
What is ESN clean or Bad ESN? Whats is the meaning of "unlocked" and if i buy a locked one can i unlock it by my self?
Thank You

I'm far from the expert so I'll give your questions my best shot and maybe somebody else with more experience on GSM can fill in some of the gaps.
bad/clean ESN only applies to CDMA. CDMA does not use a SIM card. once a CDMA phone has had its ESN marked as bad, it will not operate on that carrier. example, sprint (only CDMA network) evo 3d, the owner doesnt pay his bills, they mark the ESN as Bad for that device. if he sells the evo 3d, it can't be activated on sprint's cdma network. if you want to activate it on another CDMA network, like metropcs, it is doable, but sometimes considered a legally *gray* area.
"unlocked" in regards to the carrier of the device only applies to GSM type devices. on GSM type devices, once they has been "unlocked" they will operate on any GSM carrier.
i'm not about the band count, i.e. 4 band GSM. i would suggest looking at which frequencies are used in those bands and matching them up by frequencies and GSM/CDMA. as your profile is marked albania, i think most of europe uses GSM so CDMA will probably not be useful for you.
hope that helps some of the questions!
thank you... you were very clear.
still searching for the last question. If i buy a locked GSM phone, can i unlock it here by myself or i have to buy unlock code?
Well, doesn't all phones come unlocked in Europe anyway? Locking applies to GSM phones, and I've always thought only north American carriers do that. For example, if you, living in Europe, wanted the infuse 4G which is locked to ATT in America, you would need to unlock it to use it. Moreover, you must make sure the phone's frequencies match your carrier's. If I'm not mistaken, I think unlocking an Android phone is similar to rooting it. It's a different process all together, but its something you would do on your own.
Before Android tho, you simply need to call your carrier, tell them you're traveling overseas and you wanna use your phone there, and they'll give you the unlock code. Use some special commands to bring up the carrier unlock screen, input the unlock code, and bam, you're good to go.
I don't know if you still need an unlock code with Android phones, but if you want it, you would get it from the carrier of the phone.
You won't see any unlocking tutorials for the EVO 3d in the forums for the obvious reason that its cdma phone in America. But I'm sure once its released on Tmo-us, then there'll be a method.

Some SIM adapter can hack the carrier information and make the phone believe that it is on another different network. Has anyone tried so far?
Can anyone confirm this?
I did look on amazon and found two (adapters) you place under the sim card.
I do not know if these two products really work, and you have to cut your sim in order for to fit. I would love to use my photon on tmobile.
Just search "isim" or "smartsim" on amazon. Those are the only two I found.
I just bought one from dealextreme for $3.48 with free shipping. Now I have my fingers crossed. Hope it will work.
If I am not mistaken this will SIM unlock your phone but not bypass the US GSM radio lock on the phone. To unlock the US GSM radio bands someone would have to rewrite the radio's like they did on the HTC TP2.
since the source code has been released, would it be possible now to rewrite the frequencies for domestic use?
I am still curious about the sim unlock if it will work.
For unblocked us gsm may need the atrix radio rom

It's not a sim lock issue.
Some users have been digging into the phone via Radiocomm have actually discovered what appears to be carrier suppression code. Seeing how that it's a Radio issue vs a Android issue.... I'm not convinced this one will be cracked easily as I do not believe carriers or manufacturers are compelled to release Radio code
Just received it. The SIM unlock adapter didn't work for AT&T at least... Sad...

Can I use the GSM outside US?
I mean is it locked to other GSM carriers except att and tmo?
It's not locked at all. Only us gsm towers are blocked. Eg: you could use an att sim just fine if you were roaming in Canada.

The phone is unlocked for roaming outside the us and works fine. i just returned from jamaica friday where my photon worked fine on their claro network. for internet you may need to manually set the settings but the phone worked great.
Hello guys. Currently I'm planning to get verizon contracted razr phone on amazon. But unfortunately I'm living outside of US and can't use Verizon SIM card.
As I understood there are no possiblilities to "compeletely unlock" bootloader. But, what about those safestrap\bootstrap things? Can it help to unlock SIM?
Or it's just about changing ROMs?
Is there are any possibilities to unlock a phone for use with any other operators?
Why not get an unlocked GSM Razr.
The Verizon Razr is CDMA and locked to Verizon and has nothing to do with the boot loader.
A SIM Lock and a locked bootloader are two ENTIRELY different things. None of our discussion pertains to SIM locking, which is something the carrier does to protect their subsidy, and can be unlocked by requesting the code from the carrier, usually with an associated fee.
However, unless the LTE Razr turns out to have international gsm radios like the Rezound, unlocking the Verizon model won't get you anywhere. I don't know of any compatible CDMA/LTE networks anywhere else in the world at this time. You need to buy the international GSM version of the RAZR, AFAIK there are no real differences other than the network type it uses.
My question remains, when carrier unlocking an s9 or s9+, is there any way to make it available on different network types like say if the phone started out using a carrier that uses CDMA, is their any way to flash it to utilize t-mobile's frequency bands?
I unlocked two galaxy s9+'s that were on xfinity, which uses verizon towers. The two phones did unlock, but only for carriers utilizing CDMA. I was hoping they would be able to be used on t-mobile after unlocking, but they can't. Only messaging and data works using a t-mobile SIM card. Verizon works fine. SO my question still remains, is there a way to make it work?
I used itekimei .com to have the phones unlocked, as I found they were suggested here on XDA. And they weren't really able to answer my question either. They said it should work with t-mobile, but the conversation ended with "t-mobile is having problems with unlocked phones." This is super frustrating trying to get an answer.
Edit: I found this forum https://forum.xda-developers.com/galaxy-s9-plus/help/sim-unlocking-sprint-samsung-galaxy-s9-t3783571 which debates whether it will work or not. Also this one specifically about Xfinity https://forum.xda-developers.com/galaxy-s9-plus/help/xfinity-mobile-unlock-service-t3796349. But mine didn't work. I don't think U.S. S9's are cross compatible from CDMA to GSM. I have been searching and searching and can't find a way.
Yes, the US unit hardware is cross compatible. Heck, Verizon itself isn't all CDMA. They are phasing out CDMA soon and most of their network is LTE.
I have a US unlocked S9+ and can use any carrier in the US. You could too, all you need to do is flash the US Unlocked firmware to the device using Odin.
Your problem may be the Xfinity firmware restricting certain bands is all. Or possibly the device isn't really unlocked.
