HTC One on the Sprint seem to be a world phone. It does have a Sim Card slot available.
Most likely Sprint will be locking the sim on all US carriers and would allow you to call in to unlock the sim portion for international use. I wonder when they will allow you to do this? Iphone users usually need to wait 90 days (active account) in order to unlock the sim.

Let's hear who has done this in the next week or two.

I can confirm that the Sprint version is simlocked. I put my sim in and it said simlock activated contact customer care.

This is pretty exciting. Where is the SIM slot on the phone? I can't find it in any of the pictures... is it hidden behind a button that pops up or something?

It's on the left side towards the top. Funny thing is, the Sprint version doesn't come with a SIM removal tool.

So once I call customer service to unlock, I should be able to buy a prepaid SIM in canada and just pop it in? I'd have a new number, but I'm fine with that. I just want to play ingress in Toronto LOL.

Everytime a new device comes out we seem to have the same discussion about SIM cards.

When are we going to finally understand Sprint phones work out of a funky frequency that GMS carriers don't pick up. So no your SIM card won't work on this phone.

the HTC ONE supports all GSM frequencies making it a world phone capable of using local SIM in other countries. Thanks.
How sure are you about this ? Can you point us to an official link which confirms that?
Also is the gsm bands pre-unlocked for outside states use ?

see the section about 2G/2.5G GSM:

"2G/2.5G - GSM/GPRS/EDGE:
850/900/1800/1900 MHz
3G - UMTS/ HSPA:
Europe/ Middle East/ Africa: 900/1900/2100 MHz with HSDPA up to 42 Mbps
Asia: 850/900/1900/2100 MHz with HSDPA up to 42 Mbps"

I am looking into the unlocked portion and will respond shortly.

Unfortunately, I doubt that this applies to the Sprint version. The reason I say this is because generally if a device has the technical capability of operating on bands that are available in the US, it needs to be tested and approved by the FCC for those bands (even if the carrier distributing the phone doesn't operate on those frequencies). However, the One did not undergo such testing. Same holds true for the UMTS 1900 band. Therefore, from a GSM/UMTS perspective, it appears that the device is good mostly for roaming in Europe and some Asian countries (and even then, not perfectly since there some carriers which supplement UMTS service with UMTS 900, which apperantly the Sprint Variant doesn't do either). The ostensible lack of GSM 850 / GSM 1900 and UMTS 850, UMTS 900 and UMTS 1900 does mean that the phone will not GSM roam in most of the Western Hemiphere as well as certain countries/carriers in Asia unfortunately.

Yeah that's not the sprint version there bud, that's the international version... Hence the lack of LTE mention... Ad other poster mentioned... Less the freq was tested during FCC testing..... Good luck getting it to work on a carrier that supports freq not tested at FCC testing when they tested the Sprint version.... Same can be said for the international version coming and working on sprint... Same as why the sprint one won't work on VZ LTE... Diff freq.

if you read closely, HTC is listing all common features on the phone, then splits it into carrier specific frequencies: All HTC ONE's support the 2G/2.5G frequencies for GSM, just like previously the Motorola Photon 4G and HTC Design 4G, iPhone 4S/5. the UMTS/HSPA then has some carrier specific limitations and then of course every LTE carrier has different frequencies, hence different SKU's for each carrier. I personally have used the HTC Design 4G abroad before without any issue. I hope this helps.

2G/2.5G - GSM/GPRS/EDGE:
850/900/1800/1900 MHz

3G - UMTS/ HSPA:
Europe/ Middle East/ Africa: 900/1900/2100 MHz with HSDPA up to 42 Mbps
Asia: 850/900/1900/2100 MHz with HSDPA up to 42 Mbps
Canada/ Latin America: 850/1900/2100 MHz up to HSDPA 42 Mbps
T-Mobile (US): 850/ AWS/1900/2100 MHz with HSDPA up to 42 Mbps
AT&T: 850/1900/2100 MHz with HSDPA up to 21 Mbps
Sprint: 1900/2100 MHz with HSDPA up to 14.4 Mbps
3G - CDMA:
800/1900 MHz for Sprint
4G - LTE:
Europe/ Middle East/ Africa: 800/1800/2600 MHz
Asia: 1800/2600 MHz
T-Mobile (US)/ AT&T/ Canada/ Latin America: 700 MHz and AWS band
Sprint: 1900 MHz

I bought a One the other day assuming I could use it with a pay as you go SIM from a canadian provider when I make my somewhat frequent trips to Toronto. Can someone absolutely confirm or deny that I'll be able to do that? If not, I might go the 14 day return policy route and return it :-/
