Using Dual Sim phone in Australia - Sony Xperia XZ Questions & Answers

Recently, I've started to have random issues with phone calls not coming through to my phone. I noticed that my primary SIM with LTE has noticeably worse service than my secondary SIM. Both SIMs are on the same network, but the issue appears to be LTE-related. Whichever SIM I use, once connected to LTE the service drops at least 2 bars lower.
This is a Singapore stock Dual SIM phone with Malaysian firmware (for more reguar updates). Do I need to update the modem firmware to be more compliant with Australia's networks? Or is this something inherent to the phone?
Thanks for any help!

I never used the Malaysian firmware but I can tell you that I've had the Russian one before and my lte signal was pretty bad in Canada. I've reflashed with the Saudi Arabian fw and I'm seeing significant improvements.

Help: Hong Kong Touch Pro in Canada (Cityfone/Roger Wireless)

Cutting it short:
Got the Touch Pro for free from Hong Kong, brand new. Sim unlock (as indicated on HTC distributor website w/ IMEI and S/N confirmation).
Flashed to ROM version: 5.07.832.3 Radio version: 1.11.25.01, all from HTC website.
Using the phone in Canada, service provider is Cityfone (the phone indicates Rogers Wireless). I don't have a 3G plan so I'm using regular GSM network.
Problem: Everything on the phone works EXCEPT the phone function itself. Everytime I make a call or receive a call I can only talk for 5 seconds, then the phone mutes automatically.
Tried setting to GSM only and shutting down HSDPA, it just doesn't help at all.
Can anyone identify the problem for me? I really have no clue since I'm new to this pocket pc tech. If HK 3G phone simply doesn't support GSM network in Canada then I don't even do anything with it. If it's just hardware problem then I'd just send it back to HK for replacement.
Any input? Help please...Bump
I will tell you it definitely supports the GSM network in Canada but not the 3G network. I don't know the problem though.

Hmmm, the previous poster is correct, Rogers is the only GSM provider here in Canada. And they do support 3G and H data connections, but you need a North American version (e.g. the FUZE) to use the H speeds) It should be fine for voice, tho. I've never heard of Cityfone, but it may be a subdivision of Rogers or leasing the line time.
Where did you get the SIM card for your phone? It sounds like Rogers is not recognizing the card and is cutting you off.
I know for a fact that unlocked Raphael's will work fine on Rogers, since that's what I'm using, and I've used a lot of other GSM phones on the Rogers network with no problems at all.
If you really want to keep the phone, I would suggest checking with Cityfone re: whose network are they using, or set up a Rogers Wireless account.

I've been using the same sim card for a very long time without problem, on celphones that were purchased locally or other tri-band GSM phones in Hong Kong. I swap the sim card back to my Sony Ericsson W800i and the voice call is fine.
I used my mom's sim card (from Rogers Wireless) and same problem occurs on the Touch Pro--5 secs and the call mutes.
I'm just not sure if it is hardware problem on the Touch Pro or if there is compatability issue with the network (which I doubt since I can talk for 5 secs before the phone mutes...). Any possible way to identify what the real problem is?

Verizon M8 only connecting to 2G/GSM networks. No 3G/4G.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!

do you know the actual bands/frequency the gsm network uses where you are? the prl is going to be pulled from your sim card. have you also tried a diff sim card?

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

900/1800MHz for 2G
2100MHz for 3G
850/1800MHz for 4G/LTE

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.
so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

hmm this is quite the problem. if you can confirm you are using the same rom as the others, i would then think the issue is the radio being defective

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios

[Q] SM-G995FD on Freedom Mobile LTE

I have been trying to get my LTE working on my Samsung S8+ SM-G955FD with Freedom mobile. I have updated the CSC to XAC and GLW from the development forums and the phone will not connect to LTE at all. However flashing it to tmobiles CSC I was able to get LTE as it uses the same band 66. I initially got LTE by selecting the network operator "Home" once I lose connection from LTE to 4G it will not automatically reconnect back to LTE unless I select the network operator again. Any suggestions on fixing this?
Same issue with Reliance JIO (India) using VO LTE. Seems the phone does not support it either (the 6GB Ram Model)
up!
my 3g does work but lte not always!
I found this article around flashing csc, it seems like it's proven to work when they are the same model eg both g950w.
Keywords from the article since I'm too new a member to link directly. oneplus-5-other-unlocked-band-66-devices-may-be-incompatible-freedom

I would like to ask if you rooted your phone and changed the CSC as per instructions given in the Droidview website?
If you did, and the results were not satisfactory, then you would have tripped Knox, but gained little.
I am in the same situation, and am considering rooting the phone to try the method in Droidview.
Thanks.
I got s8+ from freedom and trust me I absolutely hate their reception. On a drive home or from I get interruptions of voice call for 5+min (highway drive) in some areas. Anywhere in US call reception is hit or miss. In Canada isnt always great other. Now for LTE well, it ok if you catch LTE signal. Allot of the times im on 4g. Speed are very slow. If im lucky I get LTE. So i don't know whether its the service or the phone but im not happy. I'll pay of this phone and move back to FIDO or on US network. Freedom is garbage to me. Im all over the city, country and north america - freedom isnt great for me. Fido was excellent but i didnt get any credit on the phones, in US fido rates are very high.

G955N signal unstable in HK after upgraded

Hello all
Have anyone faced an issue that G955N LTE signal unstable after upgraded?
I bought the Korean version in HK with CMHK carrier, when using stock AQDB firmware it went fine, after upgraded LTE signal always no data traffic almost every min., (sometimes signal dropped too and connect)
I also tried installing customs ROM and even flash to G9550 CSC but same.
Any solutions? or actually G955N 4G band is not suitable in this carrier?

LTE 4G not working on both sim

I'm on 5.1.9 but despite i activated the option only the Sim used for data traffic can actually connect to 4G. The other Sim seems forced and stuck in 3G at 900MHz (band 8)
There's no use for LTE on the phone sim unless you are lucky to live in China, India or Finland AND use a sim card of the view carriers supporting VoLTE in the OP6.
No sense reply. OP declares dual 4G on both Sim. My phone supports 4g only one sim and the worse the secondary sim is locked on 3G band 8
Are you using any custom rom? i faced similar issue on havoc rom

No. Pure stock 5.1.9
I had the same problem. But i went back to 5.1.8 and problem solved now dual 4g active.
Crazy but settings the phone on the English instead of my local language the problem seems gone.
I'm in America and I'm having the same problems after the 5.1.9 update, one SIM is always in regular GSM mode even with the dual-4G mode enabled.

That is completely false. Even T-Mobile in the US supports VoLTE. Even if it didn't though, it still allows for faster SIM switching since it was already on LTE.
Curious how you guys are checking it. Mine both say VoLTE and it seems to be fine for me.
I reset the network settings and it work for a few hours. The dual sim 4g instructions are broken .
