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 all. Soon (as soon as I end my mega carrier contract) I will be purchasing an unlocked HTC One M8 direct from HTC. I will use a nano simm from the new Cricket Wireless.
I believe this unlocked version is same as ATT&T sku. Buying unlocked, I can freely change carriers, and avoid a lot of bloat ware.
My question is, Is this the correct forum for that phone / carrier combination? I ask because I am sure I will be rooting, experimenting, etc.
Thank you all in advance!
It is and you'll find more in the international forums here: http://forum.xda-developers.com/htc-one-m8
Roms on that forum will state whether they're safe to use on the AT&T version.
I found one thread on how to unlock the GSM bands on a Razr Maxx, it seems very complicated and the slightest mistake will brick the phone. The tread was also started a while back, is there any newer easier methods to do this? I am looking to unlock the bands to use the phone on T-mobile/Walmart Family Mobile.
Does anyone know any software or quality unlocking providers who can carrier unlock a T-Mobile Samsung Light? (T-399)
Having a look around here as i post this as well.
All help is welcome. Thank You.
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.
