No development for T815? - Galaxy Tab S2 Q&A, Help & Troubleshooting

Any particular reason why the LTE variant has no developement going on?

Yeah...LOL! Because hardly anyone pays extra for a sim card option. I too am stuck with a not needed sim card and therefore no upgrade/update.

[q] lg revolution 4g unlocked

Has anyone ever seen the one click unlock or the unlock codes to get this phone to use another companys sim card... Ive checked all over and cannot fund anthing please let me know
Which company that uses the same frequencies that Verizon does were you hoping to use your phone on?
I've never heard of a Verizon phone that you could unlock... Well, except maybe their quad-band "world phones". I've had Verizon for years and this is the first with a sim card. I'm not sure, but I think the sim is just for access to their lte "4g" network, wich is of course probably just different enough from atts lte to not be interchangeable there either.
The sim card gives access to the network in general. Without the Revo is useless. I tried to take out my sim to save battery and not use my 4G radio before I relieve I could turn it off. Also, for OP I don't think there is a way because of how the phone works. Then again, I'm not a dev so I could be completely wrong.
the sim card in the revo is just for the lte access and is phone dependent it will fry its self if put in a different phone. also just a quick side note i guess verizon is moving to sim cards too (from what i heard from an associate on the phone the other day).

Yes. The SIM card cannot be unlocked and this phone will never be able to be used on a different carrier.

Single Sim vs Dual SIm

whats the difference between the single sim and dual sim models?
do they receive the updates on the same day?
are there any potential custom rom issues with going for the dual sim?
I went with the dual sim as I really need that convenience.
When it comes to development, I'm sure it will be the same update schedule. Plus I see no reason why having a dual sim would hinder custom ROM support.
What's the reason that Samsung brings out 2 versions? Is it just a different SIM holder or are there more differences? I normally use 1 SIM. But might get another private one. And thus I also wonder if it will be needing different software when I decide to root it.
I have contacted Samsung. Their answer was that there is no hardware or ROM difference.
If this is correct. I expect double SIM bays to be sold soon by other suppliers.
Ordered the double SIM now. And will do the double SIM mod. As it only allows 2 SIM or 1 SIM + SD.
Since the second SIM slot can be used for microSD card, I don't understand why would anybody want the single SIM model... especially that it looks like the dual-SIM one is cheaper?! Here's an example of both models on the same site:
https://www.techmania.ch/Product/Detail/23991212?parnr=12833993 ==> single SIM = 1075 CHF
https://www.techmania.ch/Product/Detail/23309783?parnr=12833993 ==> dual SIM = 999 CHF
the problem that the brand version is single sim
DS have DUOS on the back I hate that part, but overall better for reselling and usage if you end up needing second SIM slot. I might move from 2 phones to 1 phone soon
The ROM is not entirely identical. In comparing the two I found that the dual SIM model has several libraries that are not present on the single SIM models, in addition to the obvious settings differences to let the phone know how many SIM cards to look for.
Dual SIM model here. But nothing mentioned on the rear.
I can think of at least two reasons they'd release a single SIM version:
1. Most network operators don't like users to have a second SIM from a different operator - it's easier for the user to switch operators
2. Companies have many reasons not to give their employees dual SIM phones. Also, they migh not agree with SD cards in their phones.
Just curious.
I wonder what Samsung does with the "extra" storage space that the second SIM would have occupied for a single SIM phone?
It can't be all about the SD card slot
Question: I've read that the dual sim is the "international" version, while the single sim is the official UK version, and that some manufacturers refuse to honour warranty claims for international versions of their phones that are often grey far east imports. Does this affect Samsung dual sim phones?

Decided on the Verizon Note8... SIM card question

Can I take the SIM card out of my current Note4 and put it into my Note8? My Note4 and SIM card are just about 3 years old. Is there any lost functionality by not getting a new SIM card or should I just go to a Verizon store and get a newer SIM card? Any advantages or disadvantages to either approach (current SIM card versus new SIM card) like an activation fee or anything like that?
Thanks!
The SIM card is a nano compared to the older micro in your awesome Note4, I had one too before the Note8
You can cut the SIM card to size but there is a chance you can cut it incorrectly and have issues, also a cut SIM card is not covered when you bring it into a store.
Your best bet is go get a new nano SIM at your provider.
I cut my SIM and I am not experiencing any issues but I do want to get a new one soon.
Ok, I figured there was likely a change in something over the last 3 years. Do you know if they will charge me the ridiculous activation fee ($35, i think?)?

It has been suggested by all carriers that new SIMs be used because there have been several issues with previously used SIMs and provision functionality...in other words, there is better connections and access to carrier functions when using new SIMs...most are free from your carrier...I tested my s7e SIM and a new SIM and while they are both from my carrier, only the new SIM provisioned WiFi calling correctly and there was a considerable change in data speeds...just an idea though...

Thanks. That makes sense. I understand that the SIM is likely free. But, does anyone think Verizon will charge me the activation fee to put provision my Note8 on my account to replace my current Note4?
Thanks again!
One more question... Do i need the SIM card installed in the phone to actually go through the phone setup? I'm guessing not, but wasn't sure if it had to go through the setup all over again once the SIM finally is installed. I should get the phone today but probably won't get to a Verizon store to get a new SIM until a day or 2 from now. Thanks.

In most cases you shouldn't, and don't require a SIM card to get through the setup wizard, however I'm not sure if the process is different for US carriers so don't take my word for it.
Popping a SIM card in the phone after setup is complete also shouldn't be a problem.

I just did this yesterday went from the Note 4 to the Note 8 and Verizon gave me the sim for free. The only thing is they had to activate it while in the store so bring you Note 8 with you if you have already bought it. They didn't charge me anything however if you are upgrading through them (getting the Note 8 while there) they may.

This is perfect! I just got my Note8 in the mail today. (came a day earlier than expected)! I'll take it with me over to the Verizon store and hopefully I have the same experience as you did. Thanks!

Any Verizon users help?

I picked one of these up at nearly no cost bad screen
Before I put a screen in can Verizon users confirm its gsm unlocked. It works on Verizon based some cards but every time I put a cricket or other sim in. I get a sim card not readable.
I don't want to buy a screen if other hard ware issues first. I'll fix it myself. I guess I should just tear into it and see.

Xperia 1 II Dual SIM

Hello,
I am willing to get the new Xperia 1 II. I am living abroad, and for many reasons, I kept my native country's sim to keep my line open. Currently, I own two phones to have both lines up. But this new Xperia seams to be released with a variant getting dual sim feature which is what I am looking for so I could replace my LG V20 and LG G8 for this amazing phone.
I read online that this phone comes with different variants:
XQ-AT51
XQ-AT52
XQ-AT72
SO-51A (NTT DoCoMo)
SOG01 (AU/Okinawa Cellular)
On this website https://www.xperiablog.net/2020/04/...eria-model-number-structure-for-2020-devices/ they tend to say that this XQ-AT52 model would be the dual sim variant, but I cannot find any online resources to confirm this.
Is there anybody who knows yet what is the dual sim variant so I don't get wrong while ordering?
(I really hope it's not only the korean version to get this dual sim variant...)
Thanks!
Hello,
I come back to you guys to have some updates about this topic since now they released the phone and preorders are available, maybe someone has some details about this feature.
I really want to know if the variant sold in Europe is supporting 2 sim.
On GSMArena, they list the phone as Hybrid Dual SIM (Nano-SIM, dual stand-by) but on sony.de, sony.fr, sony.it they list it as SIM NUMBER
Single SIM.
On B&H bhphotovideo, the phone is proposed as Sony Xperia 1 II Dual-SIM 256GB Smartphone (Unlocked).
Why would they sell a dual sim capable in America and a single sim in Europe?

The model selling in Taiwan is XQ-AT52 with dual sim ( 5G/4G compatible ).
If you put 2 sims, it runs in 4G mode, 5G is only working when only one sim card inserted.
5G I only works with 1 SIM card inserted? That's not very good design.
Also, can you please try to switch between SIM card for data, does it require a reboot to active? I used to own Sony phones and they all require reboot when switching between SIMs, which is very inconvenience.
I use other brand dual SIM phone now and they don't require reboot when switching between SIM.

Do you know if the only difference between the single sim and duel sim variations are the sim tray provided with the phone and the software installed. I am wondering if I got a single sim version, if I could flash the international firmware and replace the tray with a dual sim version

Normally it should work as previously it was like that.
but the SIM holder looks different to Xperia 1 dual Version
You don't need to reboot to change or swap sim, that's what i heard and that's why you don't need a pin to open the tray.. you just need to pull it.
I guess the tray for single sim is different but software is different too.. means software can handle dual sim..
I know some people with Samsung single sim model, they put 1 sim in tray and stick the second sim on the microsd. It becomes a dual sim with micro sd.
But you have to be very good to unstick the sim from original card and stick on the microsd without damaging your sim
HI all
has anyone found a way to keep both the Sims running even when the 1st has 5G on.. Like let the 2nd sim run at 4G or 3G atleast.. but why does the 2nd sim has to be off or go off when the first one runs at 5G.
I keep wanting to use 5G at all times on my first sim.. but why should my 2nd SIM stay off. this is mind boggling why would SONY implement this on a Premium Flagship while others Like Xiaomi and others have better sim management options even when 5G
this is the only thing stopping me from getting this phone although i love it.
on a separate note.
Also someone has any idea if the Special Frosted edition of this phone releasing in Japan with 12GB RAM will be dual or single sim ?
