ICSSGS 4.2 : 3G not working in Singapore

hi guys,
I have been using the RC4.2 in india for the past couple months. both 2G and 3G were working on Indian providers.
I recently moved to Singapore, and now 3G doesnt seem to work on SingTel network. The signal shows "G" written next to it, and phone status inside Settings shows network type as GPRS:1. That means its on 2G network.
I called up SingTel customer care and the APN setting seems fine. A friend of mine running CM9 ICS beta build on his galaxy ACE has perfect 3G connectivity in Singapore on SingTel. The network types is shown as HSDPA.
Has anyone used 3G in singapore, or faced this issue? or is there any 3G connectivity fix for RC4.2? Am i supposed to use any other Radio?
Please help..2G here sucks!!

hmm...ask what modem your friend uses. Try other modems, it's easy from rom manager (rom manager-->download roms)

thx..i tried KB3 and KF1..nexus S modems posted for Galaxy S on the development forum..but faced the same issue.
my friend has a galaxy ACE..the modem listed there is S5830DDKQ8 (in the Baseband Version field..i hope i am looking at the right thing). what shall i do now? would DDKQ8 be available for galaxy S?
also, can this be a kernel issue? i am using semaphore 1.0.0sbm!

Try DXJV9

Check if your HSDPA is enabled

Display Info > 1 is enabled
Finally, make sure you are using a 3G SIM card.

i am quite sure its a 3G sim card, coz other ppl are accessing 3G on a similar sim. I keyed in the code above, and chose "DISPLAY HSPA INFO." , it says "Serving Cell Info: HSDPA:0, HSUPA:0". this means HSDPA is not enabled? What do i do to enable this? I used to use 3G back in india, never did any enabling/disabling.
thanks for the help btw..but is there a way out now?

You have Galaxy S Settings app in your app drawer?
If yes, open it and under Radio, Enable HSDPA+HSUPA.

[Q] T-Mobile 6606 no lte on any generic rom

I'm in US Indiana I have the t-mobile 6606 Z no root.
I have flashed the German, French, Spain,and European roms with the flash tool and LTE will not work with them.
I made sure that the apn settings matched, lte preferred was checked but every time all I get is edge,3g and H+.
I did notice that the flash tool will always flash the hole ftf no matter what I checked to exclude.
I tried flashing the ftf with the t-mo baseband excluded but it always flashes it anyway.
I also noticed that my phone has a 12.8 mp camera so maybe the t-mo phones have some different hardware than the others?
Could anyone with a t-mobile phone US that has had any luck getting lte to work tell me how they did it?

You may do it again.
I am also on t-mobile Z and have LTE with stock t-mobile baseband.
You can download stock t-mobile ftf file and flash your Z with baseband only.
It should contain only 4 files, amss_fs_1.sin, amss_fs_2.sin, amss_fs_3.sin, loader.sin
It should work after you done flashing.

Would I have to pull out the baseband folder and flash it? because when I use the flash tool to flash just the baseband from the stock t-mo Rom with everything excluded but the baseband it still flashes the hole Rom. Just like when im on t-mo Rom and I flash the German Rom I exclude the baseband but it still flashes the hole German Rom. ??

You don't need to.
However, flashing baseband only takes few seconds, while flashing whole file will take more than a minute.
I did mine many times without a problem.

Thanks for the video and all the help guys. That's how I've been doing it.
I don't see why it's not working for me maybe I will uninstall flash tool and re install it.
Like I said when I exclude all but baseband it still flashes the hole thing.
Probably be later tonight if I mess with it again.

Okay so I tried it again and it seems that it worked this time.thanks for the help everyone.

It's good to know you did it.

[Q] How do I ENABLE MODEM to add frequencies on c6603? (Don't mean flashing baseband)

I have a c6603.
Want to "enable the modem"
not just flash new baseband or firmware.
(Tried that already)
Can anyone provide me with info on "enabling" the modem?
I've seen it referenced in threads, but can find nothing on how to do it.
I get H+ at 850 MHz on my c6603, but not H+ at 1900 MHz
The c6602 (which has same modem), is enabled for H+ at 1900MHz
Flashing c6602 firmware and baseand has not worked.
How would I "enable" the modem to expand the frequencies it uses?
Then I could flash c6602 firmware with the baseband that uses H+ @ 1900 MHz,
because the modem would then be "enabled" for the 1900 MHz frequency.
Thank you for any and all help!

1900 MHz should be enabled in the C6603
It is on mine

Thank you for answering.
I also have GSM1900 on my c6603, and that it what allows me to get Edge/2G data right now.
But I'm hoping to "enable" the modem to communicate on UTMS_BC2 (which is the 3G/H+ frequency at 1900Mhz)
just like the c6602 does, since both models have exactly the same harware.

Thank you for taking the time to answer my question.
You are right in that UTMS_BC2 (3G/HSPA+ at 1900MHz) is not enabled out of the box for the c6603.
But this modem channel is enabled for the c6602.
And both the c6602 and c6603 share exactly the same internal hardware, including the modem.
I'm hoping to find out how to change an internal setting (or something) that will allow me to "enable" communication on this frequency.
At the top of the link you shared, GSMArena does say that it is "also known as"
Anyways, any help on changing modem settings or programming that would enable this frequency would be appreciated.
NOTE: Flashing c6602 baseband onto my c6603 did not change available modem frequencies.
Other threads have said modem needs to be "enabled" without further explanation.
Thank you for taking the time to reply.

Hello! I don't try this because I don't want to change or add new frequencies but I am interesting in this issue and I'll try to help you if I can, sorry if I won't.
Maybe this can help you:

If not, have you tried this?
1º Open the dialer

5º And now Select radio band
For now, I don't know any solution in Xperia device, in Samsung seems to be easier:

Second, thank you for taking the time to reply to my question.
I am investigating the links that you shared with me and I will be trying the c6505 and c6052 baseband swaps tomorrow. I will post on the results.

Try flashing FTF C6506 baseband only

sigh i'm in the same boat, my phone is region locked to hong kong I believe. Does it make a difference? I don't know if buying XZ from another country restricted bands, and if that's the case, has anyone attempted and successfully unlocked bands for LTE?

Volte support

Hello, I purchased a HK model Xperia 10 II (to be used in US market) which currently doesn't support Volte. Does anyone know of how to support?

As it is not on US firmware it is being software restricted from supporting VoLTE. There is no US firmware and little to no development for this phone. Sony has not announced any plans for a us version or for a US kernel.
I LOVE this phone but the lack of VoLTE became a huge issue when major carriers and shared networks announced they would no longer support phones without this feature. They're also shutting down older frequencies on towers in prep for 5G. If it at least supported Wi-Fi calling that would help but it doesn't.

Even I need assistance with similar issue, I am using a UK model in India. I am struggling without VoLTE or VoWIFI support. Can somebody help me what we can do.

What kind of problem you are facing bcz I am planing to buy form UK also

I have the xperia 10 ii and did have T-Mobile but can confirm it works on google fi with VoLTE and wifi calling support as long as you activate the sim card in a google fi supported phone first. I switch just to support this phone and get a cheaper bill
Mine has the HK firmware on it but I'm sure this will work with any of the firmwares on it. The fi sim card must be in the first sim card slot it will not work in sim slot 2

Hi! May I ask how does regional customization affect the availability of the VoLTE option?
I am using Xperia 10 II (came with HK customization stock firmware) in Japan, and my operator is Rakuten Mobile. I don't have the VoLTE option and it's kind of a huge problem since the operator is a fairly new one and has no GSM/UMTS network, so I can't make or receive any phone calls. Data works fine after adjusting the preferred network type to LTE only.
Can I do the same thing (flashing the SEA customization) to get the VoLTE option? I would like to know what exactly controls whether the option is available if that is ok.

Sony Xperia 1ii XQ-AT51 to XQAT52 Conversion possible?

Hi,
Im owning a Sony Xperia 1ii XQ-AT51 US customized and currently using it India. My phone has no VOLTE provisioned enabled( Using Airtel Carrier) . I tried all UK, RU Customization I could not enable VOLTE. Can i flash AT52 Firmware on AT51 to enable VOLTE ? Will there be a problem?
Thanks
Lokesh

It should work, but AFAIK you need to be on your region's firmware to get VoLTE. If you have a sim-enabled VoLTE like Google Fi, it'll work. Unsure if there is a customized India firmware though.
But yeah, flashing AT52 on AT51 will work fine.
EDIT: Read on another topic that someone flashed Customized SEA and was able to get VoLTE + 5G working in India. You can try that!

I'm having trouble converting from HK AT52 to US AT51. I've done it about 10 times and every time it is corrupt.
Does it make any difference that I have the green model with 12gb RAM?
Are there any special steps for getting 58.1.A.5.441 (US firmware) to work on my phone?

Hi guys
My device is the Xperia 1 III 72 but my problem is similar
I am unable to get volte to work on Jio
I have flashed the SEA firmware but did not work. Any pointers?
Thanks in Advance
