[Q] Can frequencies be changed by changing firmware - XPERIA X10 Q&A, Help & Troubleshooting

I recently switched to Mobilicity from Rogers...but the irony is that I can't use my lovely X10 on Mobilicity. Mine is X10a, and I recently flashed it to X10i (although I didn't know it will switch to X10i, but it did) using forum.xda-developers.com/showthread.php?t=825201 tutorial.
Ok, the big question is that can I somehow manage my X10 to work on the frequency Mobilicity is providing. Following are the lines from wikipedia.
"Mobilicity uses the UMTS IV frequency band, also known as AWS, to provide UMTS (with HSPA) service.[11] Using this band, user equipment transmits at 1710–1755 MHz, and receives at 2110–2155 MHz. This is the same frequency as Wind Mobile and Videotron in Canada and T-Mobile USA. Like WIND, they do not have a GSM network."
"The Xperia X10i uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 900/1700/2100. The Xperia X10a uses GSM/GPRS/EDGE 850/900/1800/1900 and UMTS/HSPA 800/850/1900/2100."
Please be easy on me as I am a newbie

Sorry buddy, that'd hard coded and can't be modified. U need a factory x10i

Thats a shame...I guess I will have to rely on the carrier to change the frequency
And thanks for welcome How come you have X10i version since you are from Canada as well.

Its flashed with 2.1

the carrier is not going to change the frequency for you.. As it looks Videotron and Mobli will survive Wind took a hard hit just today. The CRTC and Industry Canada are getting pressure to reopen the ownership debate. If that falls though Rogers will add data to chat-r and seal the fate of Wind. Then you can simply switch over and be fine.

ok, I will wait for a month or so. I guess North American handsets always had problems. I remember I took couple of handsets to South Asia 5 years ago and they werent working there, but their handsets worked in North America.
Btw, my current plan is 35+tax and it includes.
Unlimited Incoming & Outgoing
Unlimited Text (Global and domestic included)
Unlimited Long Distance for North America
Unlimited Data
Caller ID, Call waiting, Voicemail, Call Forward, 3 way calling
I doubt Rogers or its subsidaries can offer such a plan.
Btw, I am a webdeveloper who wants to get into mobile development scence as well. Any guidance will be appreciated as I am a complete newbie when it comes to mobile development.

It is funny to tell but my x10a is not working the right way
The 3G working bands are as the service menu says:
umts_bc1, umts_bc4, umts_bc8
instead of
umts_bc1, umts_bc2, umts_bc5, umts_bc6
So I can't use the 3G anymore that's because in my country none operator uses the bands that my phone has, It seems my x10a phone uses x10i bands now.

3G or No 3G

A coworker of mine just bought an Xperia X10a and is off the Germany for work she sent me a txt asking me to get her the unlock code and also to tell her if it will work in 3G while in Germany.. from what I can tell from the specs I think so.. but I thought best to ask the experts here. I know there is a X10a and a X10i I need to know if her X10a will get her 3G in Germany before I get the unlock code.
*edit* code is 6.00 is it would not be a total loss if it did not work..
thanks
So no one knows? or was it a silly q?
I don't know what services are available in Germany or what firmware you are putting on, but if it is available, it should still work. Debranding and unlocking don't take away the capability as long as it was available in that firmware and service is available in your area.

thank you.. I was hoping to hear that! I know my k850i was able to get 3g in Germany Italy and France.. so I was hoping her xperia x10 would be fine.
You need to have carrier frequencies to use the 3G. has nothing to do with the firmware but only the hardware.
10a are on 850/1900 and 10i on 900/1700/2100

That's right, 3G on the X10a won't work in Europe, or most of the rest of the world.
A little rant: Why do the US insist on always changing something instead of using the international standard? I can see no advantage in that to either their citizens or foreign travelers that visit the US. Just to mention a few: only 3 countries in the world don't use the metric system (US, Liberia and Myanmar), the cellphone bands are standard pretty much everywhere else, most countries have 220v energy (though the plugs vary in format you don't need a transformer). It's a bit like the English driving on the left side. It benefits no one.

The other thing your friend will need to check is that they have international data roaming available and also a LARGE bank account lol
She has my vodafone sim so roaming is not a problem. She is at a spa for the weekend so I can not report back but AFAIK it should be fine. I think she may want it debranded so i am thinking to debrand mine and just ship it to her as she will be there for a while. yeah I am good like that! So the consensus is it will work just fine?!

UK phone in US - 3G does not work.

I just purchased a SG SII here in the US and later found out it is a UK phone (the sales rep said it was a US model)
anyway, the phone works great EXCEPT it will not log onto T-Mobiles 3G network. All I get is EDGE which is terrible.
How can I get it to go to 3G?
Spoke with T-Mobile, even got a new sim card. No help
Spoke wth Samsung US - they tried, could not help and then said to contact the UK.
Called Samsung UK and they said it should work, if not, bring it back as it is broken!
anyway, is there some sort of settings that I can change to make it work in the US.
I also need it to work in Brazil as I will be going there and will be using the Brazilian Tim network and installing their sim card.
thank you for your assistance in advance.
The phone is suppose to be:
HSPA+ 21Mbps/ HSUPA 5.76Mbps
EDGE/ GPRS Class 12
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
Did you limit the phone to only work with 2G in the settings?
Check Wireless Network settings.
Much more better would be goto Settings->About phone, tell us what Baseband, and Kernel, and ROM version you are using.
Reboot phone.

Exactly, that phone will never work on T-Mobile USA 3G network, refund it or switch to AT&T. Makes you wish someone would regulate mobile networks here.
Edit: SGS2 should work fine on TIM Brazil.
you guys are absolutely certain that this phone will not work on T-Mobile?
what about certainty that it will work on Tim? I live in Brazil and defintely need it to work there.
Here, in the US, when I return next year, I can alway switch over to AT+T.
I need to be certain because if I get to brazil and it does not work, I am screwed because then it is almost impossible to get anything done to it.
BTW- they have been saying that t-mobile will have this same phone in a few months. How will that one be able to work? will it be possible to flash that info to this phone when it comes out?
thanks

The US T-mobile Variant is completely different from the UK model, won't be the same. Also it's true you can never get 3G with T-Mobile, don't know anything about TIM though.
T-Mobile uses the 1700 AWS band which this phone does not use so yes... You will NEVER get 3g or HSPA+ with T-Mobile U.S.

so when you say fine, the phone, 3g to get to the internet, etc etc will all work?
as it is here, the phone works great and when with wi-fi, the internet is great but EDGE sucks ass.
So, as I already know that I am beating the dead horse. 3G here with T-Mobile is never going to happen but it will work with AT+T, in Brazil, the phone for calls will work fine, 3G will also work fine too.
does anyone know about claro, vivo or oi in brazil? just wondering....
and what about other carriers in the US, will it work with anyone beside AT+T?
thanks again. this has been very useful!
EDGE runs on GPRS. Your phone matches TIM's UMTS frequencies so it will have 3G data on that network.

Why would you buy a phone without checking on what radio bands it works , its not like US has only one provider they all have different bands/frequencies.

so if I have been schooled properly. T-Mobile uses 1700 and 2100, so without the 1700 band, it wont work!
I guess I got to talk with AT+T
will any other carrier in the US support this?????

Photon in Australia

I moved to Australia this week. I brought my MoPho with me. It was a hassle getting it to work but i figured it out and thought to tell you how it went. I put a Vodafone AU SIM card in my phone but 3G would not work. I knew for a fact i was in a coverage area for 850Mhz 3G so I was pretty annoyed it would not work. Turns out with the Photon you have to manually ass the APN for Vodafone and probably a few others. I was able to get all the settings I needed from here.
http://ausdroid.net/apns/
tl;dr Sometimes when abroad you need to manually add the APN for the carrier.
I need to do that for my carrier too (Slingshot NZ, 850/2100Mhz) but after that it works fine, 3G GSM data is borked on the current ICS build though.
Ya. Im going to wait awhile before i put on another custom ROM. Still trying to get used to everything in Australia. Cant risk being without a phone. Im going to keep an eye on cm9. Until then i only have the precious data connection on my phone which is caped at 4GBs :'(. I miss unlimited.

Well. Thats a tricky question. Bellow i will list the different networks and what they support compared to the photon. Currently all three major carriers can provide 3G to the Photon. Telstra simply has a better network but it has nothing to do with how it interacts with the phone. For both Optus and Vodafone so far i have had to manually set the APNs. It was a ***** with the Optus one because of the separate APNs for internet and mms. Even though optus doesnt have umts850 and the photon doesnt have umts900 i am downloading about 4Mbs in East Killara (Suburb by Sydney) throught Optus' 2100 single band HSDPA+. I have not tested Telstra because they are so freaking expensive.
Photon supports:
800/1900 MHz (EV-DO Rev. A),
GSM 850/900/1800/1900 MHz,
UMTS/WCDMA 850/1900/2100 MHz (HSPA+ at 14.4 Mbit/s)
OPTUS/Amaysim: (I only recommend for when time is being spent in Capital Cities that support 2100 single band)
GSM - 900/1800
UMTS - 900/2100 (2100 single band)
TELSTRA:
2G - 900/1800
3G - 850/2100 (850 is NextG)
LTE - 1800
Vodafone:
2G - 900/1800
3G - 850/900/2100

after a bit of hassle i got optus working and am happy so far, vodafone is sooo bad in aus anyway.
Yea i used my sprint touch pro 2 all last year down under.
Hoping the photon puts my tp2 on the shelf.
I agree with hodie though
Optus is good when your in Melbourne, sydney, perth,etc.but i thought telstra had the better overall service.

3G issue
Hi,
Im from Dominican Republic and I got a Photon, the phone use to works fine with my carrier, but since 2 weeks ago the 3G network is unavailable. My carrier is Claro Dominicana (GSM 850 MHz) and searching for the possible problem I think that one of the motorola update block that band since is the same one as ATT. I had rooted the phone and try with custom roms and also restore it to the stock rom but with no luck. Does anyone have face this issue? Is there a solution for this?
Thanks.

Cannot run 4g. please help

Hi, I have the white s2 i9100unlock version and when I put in my
Tmobile Sim card it says that I am running on E network instead of 4g. Is there anything I can do to change this? I contact Tmobile and they say it's the phone not their line. Please help me out because running on the E network is very slow
Sent from my GT-I9100 using XDA App
The international i9100 does not support 4G. Only option would be to get a 4G enabled one.
its because the international galaxy s2 doesn't have the same 3g bands as T-Mobile (assuming you are T-Mobile USA). They run off of 1700/2100 while the phone itself supports 850/900/1900/2100. While only the 2100 band matches, if you don't get 2100 coverage in your area, you will default to 2g.

So you started another thread on this, where I also answered your question. This phone will never get HSPA+ speeds on T-Mobile USA - or what they call "4G". It lacks one of the necessary frequencies for it. It will only get Edge speeds. From what I remember on how T-Mobile USA's network functions, 3G and "4G" need both 1700 and 2100 mhz to function, as it uses one frequency for download and the other for upload.
EDIT: Here's the wikipedia article on AWS, which is the band T-Mobile uses for 3G/4G. In brief, AWS uses 1700 Mhz for uplink, and 2100 Mhz for downlink. So since it only gets half of the band, it won't do "4G".

Unfortunately, the bolded/underlined part is simply not true. T-Mobile USA needs your phone to be able to get both 1700 mhz and 2100 mhz UMTS frequencies to do 3G/4G. If your phone doesn't have one of the frequencies, it won't do 3G/4G at all, and fall to Edge (2.5G).
What if I overall another ROM? Will it help?

No. The phone simply doesn't have the hardware to receive the frequency. Nothing you can do to fix this.

You need Galaxy2 HD LTE to access 4G. That particular model is not available outside Korea at the moment. If you want 4G, try Samsung Galaxy Note or LG Optimus LTE - also known as Nitro HD, or HTC phones.

That indeed is weird and inconvenient, but I guess telco's can setup their system however they like... It may have lot to do with number of people using mobile services. In OZ we have 22 million potential mobile users using 4 major telco companies, whereas in USA, they would get most of OZ population just in New York city, let alone rest of the country.
Ah systemcrasher I think they might be load balancing the hspa+ mimo across the two freqs. Telstra nextg doesn't need to coz there's allot less people here.
If that's the case still should be allowed to fall back to a non mimo mode.
Let this be a lesson to the OP, always research all carrier pre requisites before buying, also consider other carriers encased you'd like to stay open to other options.

So the answer is the link to the wikipedia article in my quote above. It's not T-Mobile USA's doing per se - they just purchased the AWS-1 (also known as UMTS band IV) band of the spectrum. That's just the way this band is set up. Wind and Rogers in Canada also use this band.

It depends on the frequency that your carrier runs on. If your carrier uses on frequency 850/1900/2100 then X10a will work in your area but if your carrier uses another frequency other then that , then it won't work. Even if you debrand you cannot change the phones set of frequency.
As i see my carrier T mobile hr(Croatian HT) uses 1900 UMTS but somehow i am skeptical will it work!
My phone has arrived AT&T was unlocked and now x10a for Americans works in Croatia with 3G UMTS on Croatian T mobile HR i was lucky!Very happy!
