Okay, so my issue is that i have been given a Motorola droid from my girlfriend, and she does not know about cellular 3g bands. because of this she caught me a euro 3g band phone, 2100 and 900 MHz 3g only, and it is well past the maximum return times. i am extremely good with cellular internals as well as many other electronics fields. however i am at a loss for this answer, i have asked many of my cellular contacts and every one seems to just shrug.
if i can get a American or canadian Motorola Droid parts, is it possible to switch the frequencies my current droid sees? what determines this? is it just a simple antenna or is it a combination of antenna and programming? does any one know of someone who can or has done this successfully?
any help or suggestions are much appreciated
Hi guys,
First of all my apologies if I couldn't find this question in the current forums. I'm the proud owner of my imported Motorola XOOM 3G 32GB from USA to The Netherlands, and I started reading a lot in the XOOM section of XDA-Devs (already have a HTC HD2 with Android so already got a lot of Droid experience).
I've already rooted (& unlocked??) my XOOM with 1-Click Root & Unlock, but when I plug in my T-Mobile Netherlands SIM card, the tablet keeps hanging on 'Activating your XOOM..' (or something). Why is it called 1-Click Root & Unlock but it doesn't unlock my XOOM? Is it just for USA cellular?
I've also red a lot about the fact that they use other hardware in the USA for 3G data than in de EU (EV-GE(?) vs HSDPA), is this the reason why I can't use my 3G function in European Union? I don't hope so because when that's true, I purchased about 200 euro more on a 3G function which actually don't work here.
Please let me know if it's possible to use the 3G, or tell me the hard and painfull truth that it's not going to work in EUROPE ?
Any h4cks or something would be great!
Let me know and best wishes from the land of wooden shoes, The Netherlands.
Max.
Pretty sure your trying to activate a Verizon 3G version (cdma) on a uk 3G network (gsm). Not possible...at all...period...

Hi all
I just got this phone for use in Italy, and am now waiting for my unlock code to come through.
Meanwhile, and as the main question, I wonder if it ever will be a way to turn on the WCDMA 900 band that we use here (along with WCDMA 2100), since it's not supported out of the box, being an American phone.
I would like it to be a 900/2100 phone, instead of 850/1900/2100.
I'm sure the phone supports it (being much newer than my current Motorola Defy that's able to do it), it just has to be unlocked somewhere.
Any info is appreciated!
Thank you

Sorry, but that is not possible as the hardware does not have those radio antennas in the phone. This is ONLY a GSM/HSDPA+ phone not a WCDMA phone. There is not a way to change that since it is a hardware antenna change.

As far as i know (pretty sure on this), all 3/3.5G is WCDMA. HSDPA(+) is WCDMA. WCDMA is just the name of a RF modulation, and 850, 900, 1900, 2100 are just the bands the protocol can run on.
In fact my question could just be translated to: as these settings are stored in the baseband rom, we need to flash an alternative baseband to enable those, or discover where they are set.
I guess a motorola phone similar enough to the A2 (i.e. same.hardware) should suffice as a "donor" phone for the baseband rom. May be an ipothetic european A2 of the future.
Has a phone like this been found yet?

The hardware on A2 does not support this, the antenna is not setup to capture these frequencies. Just because the baseband is in the rom does not mean that you can change the hardware.... Yes technically all 3G boils down to WCDMA or CDMA technology, but there are major operating differences between even the different spectrum in them. The issue you have is that the phone is not going to be able to capture those on the hardware layer. It is similar to trying to get am radio signals on an FM radio, with an FM antenna.
Well I hope you are wrong
I think (hope) motorola has put an universal antenna on the atrix 2, it'd be anti economic to do otherwise.
BTW, 850, 900 the antenna differences surely are minimal.
It sounds more like as a RF chipset limitation on the simultaneous bands used... like three of em. "Tri-band umts".
As with the good old gsm phones marketed as tri- or quad-band, like my v525, the actual bands used were depending on where you lived.
All of this, i hope...
Did you buy an MB865, or an ME865, as they have two totally different antennas. mostly we discuss the MB865 in here.... and I can tell you that there is no way to change the MB865, because it setup that way on purpose, and locked to AT&T's signals via the antenna and wireless chipset, by Motorola. The ME865 might be a better choice I think there are two versions of that one, one is the Chinese version and the other is more international.
ME865 it's for asia only. Motorola phones found over here follow the MB nomenclature. I have got an at&t MB865.
Anyway if a €300 phone (defy) can do that, I don't see why motorola would have chosen to spare on a $ .5 part on a €550 phone (euro price tag estimation), and have to redo a whole new pcb layout if the MB865 ever comes to the old world. Even taking into account the at&t exclusivity. It's anti economic for them.
Btw I don't want to be right at all cost, please don't misunderstand my words. ;-)
Also if you look at pdadb you will find two.models, mb865 and mb865a.
I don't know if they're both real or not, but they are identical specs-wise the only exception being the lack of wcdma900 band on the "a" version.
If such version actually comes to market, i guess a baseband transplantation could be done...
Hello, Am trying to get a phone to a relative that lives in the Dominican Republic, i live in Puerto Rico where we get all the US phones(we are a common wealth of the US) so basically i got access to all US version of the phones, the problem is that on the Dominican the company that am trying to get the phone on is Orange and they use HSPA(3g) in the 900mhz. Is there any US branded phone that works on that frequency? as of right now none us cellphone company uses those, nor At&t or Tmobile or even Claro PR(all gsm).
I know that even though the company doesnt use certain frequency the phone could still support it. Have any one here know of a US android phone working on Orange Dominicana 3g network??
[Specs am looking for]
Front Facing Camera
Led Flash for the back camera
Decent size screen 4.0"+
You'd probably be best off sourcing an International Asian or European model from eBay. Most APAC/EU networks use 900/2100 for 3G.
Good luck!
I decided to go into the webpage of the company am trying to get a phone to work on, i just went trough the phones they sell, found the LG 3D which is sold here locally around my budget, and it uses the 900mhz band . My issue is somewhat resolved.
...there should be an accurate way to find information of the radios/freq. our phones hardware comes with....
phonearena.com not reliable

Cliffs Notes:
I need a phone that will operate unlocked on GSM 900 that I can also program to use MY (not the carrier's) WiMAX base station at 2.5Ghz. Recommendations?
The longer version
Title pretty much says it all.
I'm running a Lab network that does GSM/EDGE and I've also got a WiMAX base station at the 2500 band with my own CPE's.
I want to use the Sprint Motorola Photon to access all three technologies by unlocking it. The GSM/EDGE should be cake.. It's a world phone so I shouldn't (hopefully) have to dork with unlocking it OR I can set my lab system to mimic a Sprint MNC/MCC push come shove.
The WiMAX is a question mark. I know I can allow the phone access to the base station, but getting the phone so see the base station is the question.
I assume I will need to somehow tell the phone to stop looking for Sprint's WiMAX and look for my channels instead. Seems like it should be doable - it's all IEEE 802.16e. The biggest challenge I see is reprogramming the appropriate WiMAX channels into the phone assuming it doesn't scan the entire band automatically and attempt to authenticate whatever it sees (like the way GSM does).
Before I drop $700.00 on a pair of phones though, I want to know it can be done.
What say ye?
Edited to provide more background info: My lab network when running GSM runs in the 900 band. I'd read where people were using the KDDI radio (I assume from Japanese carrier AU KDDI?) to enable USA / GSM.
I get the impression that I wouldn't have to do this to operate the phone at 900MHz GSM (ETSI spec), but what about the carrier unlock? Would the phone care at this point and want to see a 'Sprint' signal or would it accept any SIM (to include a made-by-me GemAlto?)..
Still though.. Need to know about the WiMAX bit.
For that matter, what about the Galaxy SII ISW11SC version. My understanding was that AU KDDI operates it's carrier services using CDMA2000 @ 800MHz. But I have also seen published specs that this version of the GS2 supports GSM as well as WiMAX2500. Perhaps a better potential candidate?
no takers?
