[Moto X Q&A] piskr:
Hi,

the detailed description of Moto x LTE frequencies could be found on: http://en.wikipedia.org/wiki/Moto_X. The only question is how accurate it is. Regarding my experience you should be careful with Central/South American bands and ask the seller about details before buying one. I asked a lot and once got the information that Claro's from Puerto Rico only supports LTE 700/850/1700. And it is confirmed that AT&T's Moto x with initial operating system (4.2.2) doesn't work on 2600Mhz. Regarding Wiki and some claims, when you upgrade it to 4.4 (KitKat), you get 2600 on LTE. That's what I ment in previous comment about LTE and AT&T. But this is just unproved information though there isn't any 2600MHz LTE network in the USA and nobody has tested it yet. In the USA they prefer lower LTE bands (700, 850 MHz) because they can obtain better signal range and penetration through buildings. But you can gain broader bandwith on higher frequencies, that's why Americans later built more networks on 1700, 1900 and 2500 MHz.

To make the situation clear: AT&T has on the LTE the most suatible frequencies to European networks. According to the Wiki is the same with other XT1058 models, Central/South American Vivo, Claro, Movistar. But for the latest Wiki might be wrong, it worth checking before buying.

As I mentioned before, AT&T's models has other more serious disadvantages. But I wouldn't neglect the LTE capacity of the phone, the features of modern phones which firstly look uninteresting becomes very actual this year. I mean NFC (apps management, direct payment) and LTE. Although LTE is not even nearly as widely spreaded in Europe as in the USA, the situation might change in the near future. European Commission which is very innovative on the field of mobile communications, issued last year the Decision 243/2012/EU establishing a multiannual radio spectrum policy to year 2020. In this policy it not only encourages member states to develop the 4G networks but make them also commited to. The frequencies available for the LTE should be:

- 790 do 862 MHz,

- 880 do 915 MHz,

- 925 do 960 MHz,

- 1.710 do 1.785 MHz,

- 1.805 do 1.880 MHz,

- 1.900 do 1.980 MHz,

- 2.010 do 2.025 MHz,

- 2.110 do 2.170 MHz,

- 2,5 do 2,69 GHz in

- 3,4 do 3,8 GHz.

In fact most of the European countries opt primarly for 2600MHz, 1800MHz, 800MHz and 2100MHz. In concreto in France a rollout of LTE networks began, mostly on 2600MHz and less on 800MHZ. The situation regarding LTE coverage might be completely different at the end of 2014.

There is no problem with GSM and 3G frequencies, all GSM models opreate on: GSM 850 / 900 / 1800 / 1900 and 850 / 900 / 1900 / 2100 HSDPA (T-mobile and Developers edition additionally on HSDPA 1700).

To summarize, what should be advised to the European buyer of Moto x:

1. Buy a new phone (although the service is only in the USA you still get full warranty registering your phone on the Motorola website).

2. Choose the right model taking into consideration: SIM unlocked/locked, bootloader locked/unlocked, LTE band. Sometimes is worth pay more to have significant less problems.

3. Pay with PayPal (you have effective claim against the seller if you don't get the phone as described).

4. Run it at least 1 or better 2 weeks before root or change ROM. That is minimal sufficient time to find out possible malfunctions.

A few words regarding warranty, SIM unlocking, rooting, bootloader unlocking:

In Europe SIM unlocking, rooting and bootloader unlocking is legal and for natural person, any of these acts could not void the warranty regarding Directive 1999/44/CE if the warranty claim doesn't derive from such act and the operating system is recovered to the original. In the USA rooting the device is legal and couldn't void the warranty as long as the device is reverted to original. The situation with SIM unlocking and bootloader unlocking is somehow funny. As from January 26th 2013 according to the Digital Millennium Copyright Act unlocking SIM without operators permittion is ilegal. But this rule only applies to cell phones, not to for example to tablets and other devices which use SIM cards and at least data transmittion if not telephony functionality. As regard unlock bootloader the previous stand of Motorola was even more absurd: They sell developers edition of Moto x and they encouraged usesrs to unlock the bootloader but they warned them if they had done so, they warranty would be void. Latter they changed that collision by issuing an original system image for recover and announcing that they would recognize the warranty despite the unlocked bootloader.

In other parts of the word including Canada SIM unlock doesn't have inpact on the warranty.
