Re: Can the Jolla phone be used in the united states
 
I don't know single phone top of my head that supports EU LTE bands and a single US carrier LTE bands. US has it really complicated as big carriers have cut some of the frequencies to different bands for separate carriers.
Anyways thinking on what SoC they have on Jolla LTE should not work over in US.

Do we know Jolla hasn't gone through FCC? I don't remember how it went back in the N93 etc days when plenty of American's did order their Nokia's from overseas. N95 at least had its US versions.

Without FCC declaration of conformity a device generating RF emission cannot be used in US territory.
And considering that we are talking about a mobile phone, it is not exactly practical try to hide from it :D

I don't think the FCC can enforce any individual who brings a phone from abroad to do anything. Think about tourism for exmaple. What happens if I get a Jolla and decide to go to the US for a holiday/business meeting/etc.? The immigration forms ask a lot of questions about drugs and previous criminal convictions but nothing about devices that aren't approved by the FCC.
I doubt it's even legal that the FCC can confiscate anything that you own. If anything, it's impractical. If you get a Jolla, in fact, if a buch of you get a Jolla and it works in the US, it will be a drop in the ocean as far as RF transmissions are concerned. To be honest, I wouldn't worry, but I don't live there so it's up to the invidual ;-)

This changes a lot when you are commercialising devices, however.

I wonder what is the SAR value for Jolla with LTE + WiFi hotspot working at the same time, to pass the FCC it will have to be not higher than 1.6 W / kg.

* 3G-HSPA+ (850/900/1900/2100 MHz)
* 4G-LTE (700/1700/2100 MHz)

The specs for the HTC First and One mini are below, and for the latter there are indeed variations by region. As someone who has recently signed up to a contract with Vodafone UK (800/2600MHZ LTE), I hope they've used the European variant in the One mini.

Pretty sure whole EU will be supported (eu commission and regulatory bodies) us is wild west once again (ounce again, didn't you guys end with imperial ties?)

SAR to head 0.546 W/kg, body 1.470 W/kg (See http://jolla.com/guide/#sec-17). To head it is less than N95! See http://www.nokia.com/global/about-no...r-information/

cy8aer: That may be SAR during regular operation, unless they meant maximum possible use case. SAR of mobile radio + WiFi is always higher than just mobile.

From the community FAQ:

Quoting the sticker on the box: "GSM: 850/900/1800/1900 MHz, UMTS: 900/2100 MHz"
That's not good for T-Mobile really. Most probable result - we'll have to wait for another production batch.

Not even pentaband 3G? That's a serious disappointment, and surprising especially coming from Nokia alum (who have historically been very good about having their unlocked phones be global 3G).

May be they tried to cut costs? Device is already overpriced for the average level of such hardware. Better modem could increase the price even more.
