[Q] LT30at doesn't pickup 3G on T-mobile??

I have an Xperia TL I purchased and unlocked, and it works fine making calls on T-mobile, I changed the APN settings so MMS works fine, etc, but I recently noticed that the phone NEVER has 3G, it's always either on Edge or 4G, so do I need to change the baseband to pickup 3G on T-mobile ? I'm guessing maybe AT&T uses different frequencies for their 3G?
Also my wifes LT18i seems to never get 3G after ICS update either. Hers is factory unlocked.
Is it possible to call T-mobile and have them send the correct settings over the network ?
Thanks a bunch for any help!

Flash the European baseband. That enabled the correct frequencies.

I don't think either T or TL supports the 1700

The LT30p does support it but not the LT30at

With right radio fw, lt30at does 1700...

So I have a LT30AT from At&t, which firmware I can flash to use it on the tmobile network ? will this "LT30p_9.1.A.0.492_Generic Italy(1265-1589).ftf" work ? Thanks

Sorry for the noob, I've been searching the forum and I assume that just flash the at&t phone with any of the European firmware and I should have the UMTS BC_4 band to work with the 1700 frequency (but without LTE). Is this correct or am I missing anything ? Thanks :fingers-crossed:

Yeah, you should be good to go with any European firmware. As long add it shows band 4 enabled. LTE also works, you just can't access settings from the normal network menu.

So if I started out with the stock ATT, should I flash the European with everything wipe or should I keep the baseband LTE exclude? Thanks

Any updates on this? How do you get UTMS_BC4 for the "Working bands?"

I flashed the Europe Version and my phone is now showing LT30p and It showed I have UMTS_BC4 in the configuration test: *#*#7378423#*#*
But I'm using Straight Talk with an AT&T sim now so I'm not sure about Tmobile

Did you exclude baseband when you flashed? Which UK verison did you flash? I did lt30p 9.1.a1.140 generic uk.

I think I did exclude baseband, been so long, can't remember . I think I got the 9.1.A.1.1.40 for my build

hmmm, interesting. I hope someone else can chime with more info on this

...Or mabye I did a 2nd flash from the European firmware without exclude baseband so I that now I only have H+ showing in my icon (and I'm on ATT network)

Do you still have the LTE bands LTE_BC4 and LTE_BC17?

This is what showing in my working bands:
GSM850,GSM900,GSM1800,GSM1900
UMTS_BC1, UMTS_BC2, UMTS_BC4, UMTS_BC5
LTE_BC2, LTE_BC4, LTE_BC5, LTE_BC17
Phone Software Version:
1262-6309_9.1.A.1.140
GENERIC - user
File System Version:
GLOBAL-HSPA_9.1.A.1.140
So my guess is you can always backup your current firmware and do the flash, see if it working for you, if not go back to whatever you have before and try again...

Thanks for all your help and info gokusay99!! I'm just going to wait until some other members chime in.

Bump.....anyone?

Dual SIM flashing CSC for VoLTE and Wifi Calling

Hi All,
Is it possible to get a dual sim model (I am in Canada), and then flash a canadian CSC that is meant for a single sim device so i can get VoLTE and Wifi calling? What would be the best way to get the dual sim version to use all features of the Telus network?
Thanks!

I imagine flashing the CSC of a single sim device would mean you'd lose access to the second sim slot. I'm in a similar boat with an unlocked single sim note 9 and while I have voLTE I have no wifi calling on verizon. I just flashed verizon CSC and no luck.

You will need the WiFi app from vz firmware. What model are you using?

Can someone else also confirm? I am reading a bit of conflicting information. If I flash a Canadian CSC, do I lose dual sim capabilities?

by default : XAC
so if you stay with XAC active CSC you wil have Volte for Bell-Internet , Rogers , Fido , Telus and Freedom Mobile

Your best bet might be to wait until a rooted combination ROM comes out for your model. Root allows a lot more flexibility with international devices and the firmware they can run.

Hi thanks for the response...but i'm a little lost...what does this mean? Will it work on the dual sim model, or not? thanks!

I'm not on a dual SIM Note 9, just a single, But the topic & processes here are interchangeable & the info I need fits this thread so I figured to ask. Sorry if I offended anyone.
What about note 9 Canada snapdragon model SM-N960W ESK (EASTLINK) which is my current setup. Phone is carrier unlocked. Question is Can I use the hidden code on the phone that looks like....
*#272*555777555333555# where the 5s 7s & 3s would be my IMEI? select BMC (Bell Mobile Canada) and CSC will be changed? Or To change the CSC and unlock wifi calling do I Flash bell firmware and if so do I do the phone code change after installing bell firmware? I hear that is the process and once completed I just pop in my ESK (EASTLINK) SIM card and I'm good to go & should have wifi calling & my current working Eastlink carrier. I hear I'll end up with just bell branded phone & bloatware & have to wait for bell updates not Eastlink ones.
--------------------------------------------------------------------
#################################
--------------------------------------------------------------------
Do I pick option: sales code change
or option: network code change
--------------------------------------------------------------------
#################################
--------------------------------------------------------------------
Here is my service provider info, also I'm still on bootloader v1 & not rooted.
Second of all could I Flash XAC firmware then boot up with bell sim in phone, I read XAC phones will pick up carrier of the first SIM that is put into the phone. I have a bell SIM but the SIM isn't activated so will it still work? If it does than after that I go back to my Eastlink SIM?
Right now I'm on Android v8.1.0 because I wanted to keep call recording:
Can anybody help me out? I need the process clearly stated & proven to work. I've been researching for days and see a lot of contradictory comments & various methods. I'm not dumb, rooted many phones (not this one.... Yet) but am not familiar with every term for things. Much thanks. Any help would be greatly appreciated!
If you need any more information from me please let me know, I check XDA Forums daily.

The XAC will adapt to any SIM put in the service from a Canadian carrier. If you put a Bell SIM in and then switch to Rogers. Once you out that Rogers SIM in, it will adapt and convert automatically.
Instead of using the dialer code, let the firmware do the work for you. All carrier sold devices in Canada are XAC.

If i do that my phone will be blocked as soon as i turn
on my device because in my country you can't use phones from other countries directly you have to register them to the network but it cost almost a new phone so you take an imei of an old phone and paste it the new one because older one's imei has already been registered to the system but you need a box to make it and i don't have the box i need to go out to fix it in a local phone store but the virus scares me.i know It is so much complicated.
Also i tried your method as my phone is rooted there are only 4 sub options under call.You have to root the phone to make an imei repair.

Question S21 Ultra Hong Kong (G9980) can not flash CHC rom

When I flash CHC rom via Odin. It says successful. But when I first setup the phone. It is stuck at activating phone page. I agree with all terms. When I click on Next, nothing happen. I can not go pass that stage. With TGY or BRI rom, there are no problem like this.
I want to change to CHC rom for native call recorder. I have try install TGY rom, then use Samkey to change csc to CHC. It restart but still there is no native call recorder option.
Anyone have the same issue?

Hey, i have a question for you since you own HK version.
Are you living in HK?
Does it miss any feature like Volte? Or 5g?
Anything worth noting before importing one?

No s21 has radio in any region. You can download FM application from the store.

Ummmm sorry but I read that the snapdragon version had a radio fm. Is not true ? Thanks again

Does the G9980 have a 5g Network Whitelist like the Note 20 Ultra N9860 ?
Anyone been into the service menu to verify?

I have tested the 9980 in my region which is kuwait.
Dual sim works, volte works, 5g on sim 2 only, u ca not have both 5g.
Haven't tested call quality tbh and just went with the exynos that is being sold here.
Also i have some friends who reported that they lost 5g after some updates.
So you guys can check and make sure.

CHC firmware received update today that enables 5G on both SIM.
TGY/BRI should follows.

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!

Never used Jio app for making calls. VOLTE WOKS FINE when you flash the XQ-AT52 SEA firmware. But going back to US Customized needs updated firmware 288

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
