Over at http://www.xperiax1.net/forum, there is a report that, even though the phone setting on the Xperia shows support for 850 Band, the hardware appears to be missing from the Xperia that was shipped from Clove.
I cancelled my pre-order from Clove until this gets sorted out.
Here is the post:
"Guys,
OK after checking and checking again and despite being told that the X1 supports 850 and 1900 3G the device turned up today and guess what? It does not so I can't get Rogers 3G out here in Canada!!!!!!!
Going to the phone settings shows that the device can be switched into the correct mode but doing this seems to have no effect.
I can only guess that the device has the software to support the band but the hardware does not.
So be careful folks, while you will get great Edge coverage you will not be able to get 3G!!!!!!
You have been warned!!"
I think it's pretty well established that the X1i has UTMS bands 900/1900/2100. Europe uses 900 and 2100, and most reports say the 1900 band is working on ATT's 3G. Of course this requires you to live in an area with 1900 3G coverage, not just 850 mhz 3G. Sounds like he lives in an area where Rogers only has 850 mhz 3G available.
I looked at the 1900 and 850 3G Band coverage in the US on ATT. 1900 Band actually covers more area than the 850 Band. Is there any disadvantage to only having 1900 Band in the US on the Xperia?

850mhz is good for getting a signal indoors, since lower frequencies can travel through obstacles better. So no 850mhz support means you might get a weak 3G signal indoors, or no 3G signal at all.
Then again, you might just be living near a 1900mhz cellsite/tower that gives you a strong signal indoors, so YMMV.
Thank you. So do phones with both 850 and 1900 Band support use both Bands at the same time? Or, if not, how does the phone decide which band to use. Is the 3G speed the same on either Band, provided you get a good signal?
One issue that sways me more towards the X1i is the better video frame rate - 30 fps vs 24 fps on the X1a (because of the stupid Qualcomm patent issue here in the US)

Phones with both 850 and 1900 only use one at a time, but they can switch transparently from one to the other in areas with coverage from only one band. Exactly how it chooses which band I'm not sure (it could be network load, signal strength, etc).
Technically speaking, 1900 can offer more speed because the faster frequency allows for higher data rates. But since it's all just one 3G network, there should be no significant difference in 3G speed between 850 and 1900.
The Qualcomm patent is a tough reality for people that want the X1 for the US, and unfortunately there's just no way around it. If you happen to travel internationally frequently, the X1i will obviously be the prudent choice (you still get AT&T 1900 coverage, but also 2100/900 for virtually every other UMTS network in the world).
I found a new article with someone claiming to be receiving ATT 3g in an 850 only area. He states that none of the 1900 only devices he's tested receives a signal. He also said that SE reps he contacted claimed X1i support for 850 3g bands as well (yeah, I know not that credible).

Not getting my hopes up, but can anyone with an X1i confirm any of this?

He's trying to verify if it's actually 850Mhz now. Still not 100% sure.
My provider (Telstra AU) uses UMTS 850 Mhz for their NextG network.
I've always wondered why my coverage was garbage.
Now I realise that my Atom Life has no access to the 850mhz band - only 1900 and 2100.
Is this a hardware level restriction, or are there updated ROMs etc that will allow me to use the 850mhz network?
Anyone has the answer to that?
I too like to know if there is a way to enable the 850 band for either 3G or GSM.
I have an old duel band phone that i was able to turn in to a quad ban with just a new flash, so that makes me wonder if it is possible with this phone as well.

Would be nice because with 850/1900 umts you would also be able to use it with AT&T and Rogers in NA.
I live in the U.S. Virgin Islands.
We have AT&T wireless 850 band 3g.
I want to buy this phone but the idea of not being able to get 3g on it is scaring me.
I heard it has 850 band 3g built in but it is turned off by htc.
Is this true?
Do it have a crack?
Can you tell me what i can do?
There are 2 versions of this phone:
1) The T8282, which doesn't not have the 850 capability at all (not even crippled). This phone will not work at 3G speeds down there, if you're only on 850.
2) The T8285 (Telstra - Australia) version, which does have the 850 capability. You can find them on eBay - and they're generally a little more expensive. I live in the US - and own this version. The only problem I have in Chicago though is that AT&T also uses their 1900 frequency in many areas downtown. I only get Edge speeds down there, but as soon as I'm outside that area and close to an 850 tower, I get 3G speeds again.
Good luck!
It would not be the first time HTC did that.
Remember the touch diamond.
Hi,
I bought MyTouch 4g from US and unlock it. Now, I am using the same in India. The problem is that I cannot connect to 3g network in india.
I googled and found that MyTouch 4g recognize 1900 MHz frequency as 2g and in India, 3g works on that frequency.
Is it possible to make MyTouch 4g listen for 3g on 1900 MHz? Is it possible thru Radio rewrite or something?

My friend has the same phone. Got it from US and 3g is working with Airtel. Make sure that your sim is 3G ready. If it is old then it wont even search any network when in 3G mode. MyTouch 4g supports 2100 MHz. Airtel and every other 3g operator also uses the same Bandwidth in India. You don't need any radio flashing.

Hi Sagar! Thanks for the reply, I took my friend's sim (which is almost a year old), and tried but no luck , I checked the airtel site and they claim that to use 3g, you do not required new sim, the old one works.
I am really confused!

The myTouch 4G is designed to use on the T-Mobile network with HSDPA 900 / 1700 / 2100
The 3G network in some countries will be different. You should have this frequency to enjoy 3G service.
This is preset in the hardware itself, so can't change by flashing Radio. Try using some other carrier sim cards.
Always remember to ensure the compatibility of the carrier before purchasing the phone.
ummm , probably i got the same problem
im in china and when i connect to 3g network the phone displays 4g icon on the top ....

That's not a problem. myTouch 4G is designed for T-Mobile HSPA+ Network.
If your phone displays 4G icon, it means that you are having an HSPA+ network (speed > 14.2 Mbps)
I think you are on China Unicom network, if yes you can enjoy high speed network same as T-Mobile.

Hi, Thanks for the reply, the carrier that I am using has 3g frequency on 2100 Mhz and as you said, mytouch 4g supports that
HSDPA 900 / 1700 / 2100
so, technically, I should get the 3g service, right?

Technically i think it holds good....may be some other compatibility aspect.
I suggest to use the carrier TATA DOCOMO, since they use the advanced technology of NTT DOCOMO, JAPAN
Go through this Wikipedia link. Try changing the carrier sim until you reach the compatibile one.

Technically you should but may be you are in an area where there is no 3g coverage? Just guessing.

Yeah, manish might be right. Check whether 3g network is there and make sure that in settings->wireless n networks->use only 2g network is unchecked.
it should work. I don't see a prob with the phone as it worls here in Karnataka. Try using vodafone 3g too.

Hey Felix,
Just now I asked my friend (who owns MT4G) about airtel 3G in Ahmedabad. Airtel 3g is not yet deployed there it seems. That's what he told. He is getting 3G here in Bangalore but when he visited he dint get 3g. Vodafone has 3G there I guess.
No issues with phone I guess.
BTW, I am Diana's classmate.
you can find my email address in some of her forwards

See, world is too small!
Back to the point! My wife has HTC G2 (HTC GSM Hero) bought from India only, she is getting Airtel 3g, and I am not! ,
In any case, I am going to get a new sim card tomorrow, and also, I am going to check 3g service with TATA DOCOMO, as I checked with them and they are providing 3g services on HSDPA 2100 Mhz.
So, let me do these test cases and will let update you!
Thanks,

Read somewhere that Airtel has 900 Mhz band in some circle. It might deploy 3g in that band in some circle where it dint win 2100 Mhz band e.g. Gujarat. Tata Vodafone Idea won 2100 band for Gujarat.
It seems Airtel deployed 3G on 900 MHz band in Gujarat. your wife is getting 3G with the phone which has WCDMA 900/2100 Freq band support. MT4G has WCDMA 1700/2100 but you are not getting 3G. so logical conclusion is Airtel has deployed 3G on 900 Mhz. Try switching to Vodafone/Idea. You will get 3G if this is the case.

The T-Mobile myTouch 4G is designed for band frequency HSDPA 900 / 1700 / 2100
It uses HSPA+ (Evolved High-Speed Packet Access) network of T-Mobile.
Even if it's build with HSDPA technique & a maximum download speed of 14.4 Mbps,
It is termed as 4G not 3.5G because it uses the T-Mobile HSPA+ network (speed upto 42Mbps) all over the U.S.
GET THE FACTS CLEAR BEFORE YOU MAKE A COMMENT ON THIS FORUM
@above, FYI, WCDMA is the Physical layer technique for HSPA or HSPA+. So when u say it is HSPA/HSPA+ network your phone is using WCDMA for phy layer.
PLS DON'T COMMENT WHEN YOU DON'T UNDERSTAND THE POST.

I had already checked on their site. It supports 1700/2100 for HSPA(+) network and doesn't support 900 MHz

Wrong. MT4G doesn't support 900MHz band, only 1700(AWS)/2100. Refer to official HTC or T-Mo specs on their respective sites.
Additional possible reason for not having 3G is - you need the correct APNs entered to get the cellular data working.
Hi Friends,
Finally, getting 3g network (sometimes 3g and sometimes 'H') with Airtel only, I did these things
1) Change the sim card, as my sim card was around 6 years old!
2) On my carrier's site, it is not written that I need to request them to start 3g, but actually, we need to send sms '3G' to them, and then they will enable 3g network
3) I did my network mode to WCDMA only,
Some facts
- Airtel Gujarat 3G runs on 2100 Mhz
So, in nutshell
MyTouch 4g works in India with Airtel 3g network !
Thank you all!
Cheers,
Felix

Haha. I told you to change the SIM at first..
Yeah, even i thought 2100 MHz should be freq as it is the same everywhere else. Plus, I was just thinkinig about 900 because airtel dint get 2100 band for Gujarat. But also read somewhere that it tied up with idea for that frequency. So all in all, all is well.
I know it's an old thread. But incase if someone still looking for clean answer on which handset to buy for indian 2G and 3G neworks.
1. Technically AT&T US should do.
2. It should be having 2100 MHz (MegaHertz) 3G HSDPA (Indian carrier use this band to DOWNSTREAM data on 3G band) + 1900 Mhz (Indian carrier use this band to UPSTREAM data for 3G)
If any one of these (HSDPA 1900 / 2100 MHz) is missing from your mobile handset, Then your 3G will not work in India.
3. 900 and 1800 and 1900 MHz for 2G / EDGE / GSM / GPRS
So in all it should be like this to cover all indian operators
General 2G Network : GSM 900 / 1800 / 1900
3G Network : HSDPA 1900 / 2100
