no 3g on x10 mini pro - Sony Ericsson XPERIA X10 Mini

Hi. I'm having a problem using the 3G on my X10 Mini Pro. It was bought on the USA, but from the begginning I was using it here in peru. At first, I didn't used data traffic because I haven't accquired the mobile internet service. Many months after the purchase, I updated it ti android 2.1. Now, a month ago, I accquired internet service, but it was a bit slow for me. At first, I thought it was because of the provider, but now I realized its because the phone is only connecting with EDGE, not 3G, even when I do have 3G coverage. Here's the phone info:
Model: Xperia X10 Mini Pro U20i
Sales Item Number(on the back): 1237-6807
build.prop "ro.product.name": U20i_1238-0199
Service provider: Movistar peru (716-06)
Also, when the 2.1 update started rolling out, I updated it with the Generic Nordic, changing build.prop, but now, seeing the 3G doesn't works, I changed build.prop to the original values to install the original firmware, which was now updated to 2.1.
Does anyone knows about a solution?
Thanks in advance.

If it was bought in the US, it may have the hardware for the wrong 3g frequencies. u20a and u20i do not use the same frequency for 3g.

Hi. Thanks for your help. Is it just a software restriction, or hardware limitation? If it's the first, maybe flashing a u20a firmware could solve it...

it's a hardware restriction. But you could have bought a u20i in the united states. Double check what frequencies your carrier uses for 3g and also which frequencies each model (u20a/u20i) supports. Then try flashing firmware that works for the model you have. Best of luck!

Difference Xperia X10i and X10a

Hello, can someone pls explain to me the difference between the xperia x10i and the x10a. And is one better than the other? thanks
x10a is the american version x10i is the european version.
I live in the usa, should i be concerned that i just purchased the x10i. Will it hinder any of the features and such? And thanks for your quick reply.
i think you use Edge instead of 3G..

the difference is the radio bands, you should be fine if your cell phone provider supports the same cell radio as the phone. I have a 10i and I get 3G with T-mobile usa
The X10a works with AT&T 3G in the US and Rogers in Canada, while the X10i 3G works with Tmobile in the US and, I believe, Wind in Canada. The x10i will work with Edge on AT&T and the x10a will work with Edge on Tmobile.
Very helpful guys thx
Where do i get one here in the states at a reasonable price? X10i...
X10a FOR TRADE OR SALE IF IT HELPS YA!
I actually have an Xperia X10a that is newr new and MINT! However, I can't use it here in Canada on my Wind network Sooo if anyone out there wants to trade their X10i for my X10a...give me a shout!
I have a new X10i (used for a couple of days) I would love to trade so I can get my at&t 3g going

Some differences
So given the fact that ive used both X10a and X10i firmwares (accidentally ) I have noted some differences between the two. Firstly it should be noted that the X10i firmware I was using was - X10i Generic UK (R1FA016) -, and the current X10a firmware im using is - X10a Generic America BR (R1FB001).
Here are some things ive noticed that seem to function differently between the two.
1) I use Qik a lot to share vids with distant family. With the X10i FW I could use the "high quality" video setting and with the X10a I cannot.
2) With X10i I had access to the "auto internet settings" feature and with the X10a I do not.
3) Handcent. Works fine on both but with the X10i I had no problems with all the customization features like setting background images and with the X10a when trying to use images for background it causes FC every time.
4) Battery life. Seems to have been better with the X10i FW. Don't know what thats about but Ive definitely noted a difference.
Seems odd to me that these types of things would occur between the different FW versions?? Especially considering that the generic X10a R1FB001 is actually a newer version as I understand it.
Anyway just thought that id share that with all.
I live in Europe now, and I bought my X10i in UK, but from time to time I go to USA and Colombia to visit my family. Is there any way to get 3G instead of EDGE working there (besides the provider). I dont know a lot about this but If I flash the phone should I have to choose X10a or X10i and I can switch it? or it is pre-factory determined?
thanks for your help
maybe we have a difference of memory ram
hi dear
i have the same issue i didn't knew that there is a diffrence is there anybudy who has xperia x10i please contact with me 4165255226 thanks

At the moment, I am away on a trip but I found in my Generic World firmware a setting that you might want to try and see if it will work...
First enter *#*#4636#*#* in the keypad...
Then press Menu key (the left one)...
Pres the "Select Radio Band" (Not sure if this is available with other firmware)...
Selections are Automatic, Euro, USA, Japan, AUS, and AUS2...
If it works, then you can have X10i and X10 in your phone...
I just switched back to an X10a rom. When I first debranded AT&T I only found X10i roms. The boards all seemed to say there wasn't a difference between them. I recently became aware of certain apps like Google Earth that run only on the X10a. That's the main reason I switched back to the X10a. X10a seems to have an advantage, possibly due to some North America only releases for certain apps.

X10i is probably a good fit for Pakistan.

[Q] Can x10a use 3g in Asia?

I tried searching, but the only similar thread I found was one about x10i being used on Wind. Not sure if its the same though...
I'm flying to China and HK next month and was wondering if 3g would work there if I bring over an unlocked x10a. I flashed it to Nordic x10i for the 2.1 update, but I am assuming the bands is a hardware issue.
If it known to not work I'm just going to leave my phone in Canada and bring over another phone.
Thanks!

哈哈,我用中文回答你吧,你这些英文都用什么翻译的阿,牛头不对马嘴,语法都乱七八糟,外国人可能都看不懂,建议你还是会中国的索爱论坛好了,x10a在中国能用的。

[Q] Australia: X10i has 3g on Optus but stuck on EDGE on Telstra?

Hey Everyone!
sorry this isn't directly related with Roms etc.
BUT hoping someone here can help me out!
I have an X10a i got with telstra - (running Trips MIUI)
my Partner got an X10i with Optus, under insurance then once her plan was up changed to Telstra with a new phone. She got her phone stolen so she grabbed out the X10i and put the sim in, it works fine. but is stuck on EDGE not getting to 3G...
it's definitely not the sim card because i put her sim in mine an it got 3G (after about 15-20mins.
Put my sim in her's and mine gets only E.
Checked all APN Settings are all good, exactly same as mine... Grrr
i searched and read on another forum that apparently in America or something on Rogers the X10i will be stuck on EDGE and wont be compatible with 3G.
what about if i flash X10a Firmware to the X10i? could that free it up?? or is she STUFFED and stuck on Slow ass EDGE...
Gonna try that now just incase!
any help will be good!
Thanks Guys
Here's more details on her phone:
X10i
Baseband. 2.0.49
Rom: TripnMIUI 1.0 final

Thanks, Did explain it. obviously is hardware related so no matter what i do she's going to be stuck on EDGE!
it's not too bad, but still a pain not being able to run at full potential!!
thanks again

[Q] VERY Intermittent Service (3G HSDPA etc)

Hi,
I have a SE Xperia X10i that I purchased the other week which I had unlocked via the SE servers in a phone shop as I wanted to explore the full potential of this phone. Now it is second hand so bear this in mind....
It was originally locked to the Three network in the UK, I was on O2.
The original phone had 2.1 Android on it.
After having it unlocked I rooted the phone and also installed xRecovery version 3 and then installed CM7-ZMOD CYANOGENMOD 7 V3 from 19/08/2011 which is Android 2.3 and also Baseband .71.. I love this ROM thanks to zdzihu for producing this.
I have a problem with my network service.. It drops in and out all the time.. sometimes and can have a full signal at one location and return to that location 2 hours later and get the dreaded (No Service).. Also if I go into searching networks.. it also says no network providers can be found.. even when I have a signal!!!!
I jave tried the SIM in another phone LG and it works fine at that location. I have also tried another SIM, 02 in the phone and I get the same network drop out behaviour.. I go into Bristol every day.. quite a klarge city in the UK and I am sure that the coverage is there.. well actually I know it's there..
Now I have I got a Baseband problem or a phone hardware problem?
Anyone that could help I would be grateful of assistance.
Many Thanks.
Anyone??
Okay as I didn't get a reply to the original post I shall try a different tact....
As I am getting very intermittent phone signals (GPRS/3G) etc and the WiFi and GPS is okay would it be possible to downgrade the BaseBand version as I assume that this is what drives the functionality of 2G and 3G signals?
I am currently on the following:
Model X10i
Android Version: 2.3.5
Baseband Version: 2.1.71
Kernel Version: 2.6.29-zdzihu-19082011
Mod Ver: ZMOD
Build Number: CM7-ZDZIHU-MOD.
I know the Basebands are location dependent, well some of them. I live in the South West of the UK if it's important
Many Thanks
Paul
You could try switching to another rom, who knows, or maybe switching to another sim card

Yeah I have tried 2 other sims from different operators and also about 5 different ROMS.. (Wolf, Ultima, TEAM etc) No change... I just wondered what the process was to try a different BB.. (lower version).. If not I may have a HW problem..
Thanks for the response.

Try downgrading to 2.1 with baseband .67/.54 and see if that resolves your issue. If not, then it may indeed be a hardware fault.

Problem to connect to 3G

hi everybody,
i have a UK T-Mobile Motorola Atrix that i received as a gift (MB860; 45.31.2.MB860.T-Mobile.en.GB; android 2.3.4). I live in Morocco where there is no T-mobile. I try to set the phone up to get 3G connection but it never works. it keeps trying to synchronize and changing the signal from normal to 3G to H and so on.
i tried my simcard in other phones and it works and I tried other simcards with 3G in my phone but still the same problem. i called my network technical service and they told me to upgrade the OS. i did it since there was an update available in the t-mobile web to the version mentioned earlier yet the problem persists.
when i see other phones with android there is a option to activate the 3g that i don't have in mine, i think because it's a t-mobile version.
can anyone here give me a hand with this?
thanks in advance.
