Hello there folks, i have a problem and hopefully someone in this forum could help me. Recently i bought a unlocked (international) Xperia Z3, model D6603 from Amazon. (its suppose to be a new unit, but i have my doubts since the box came unsealed, although the phone looks in perfect shape)
The thing is that the damn phone doesnt have any signal after inserting the nano SIM. The SIM is well insterted, the APN parameters are also well set, so i dont know what could be the problem.
Fyi..I live in Guatemala, my Carrier is Tigo, and the band Tigo uses for LTE is 850 or Band V, and the phone is supposed to work with these bands.
Also, i went to a Cell Phone Retail store, and tried my SIM in an exact same Z3 unlocked model, (D6603), and worked perfectly.
My quiestions are:
- Is there something else i need to configure?
- Could this phone be damaged?
I really appreciate someone´s help, advice, or orientation.
Best Regards and a happy 2016 to all.
Christian Schippers
P.S. My Carrier didnt want to check my phone because i didt buy it there, so i dont have any support from them (obviusly)
1. Does your SIM work in a different phone?
If no, have your carrier replace your SIM card.
If yes, you might have bought a blacklisted (stolen) phone. Maybe it's not stolen, might just be damaged. If it's damaged, go to Amazon and file a support ticket.

Hi guys
So, I got a friend that is going to Japan next month and I thought that she can buy me a new cell phone (galaxy s4 or xperia ZR) there.
I've been reading on the net that it is really difficult to buy a cell phone or even a sim card if you are no resident. It depends on the store that you are buying.
My question is: Is this cell phone going to work in my country, this case Brazil.
I asked this because in the past Japanese cell phones didn't use sim cards and networks where different, and I don't know how is it now.
Also, it can be network locked so it would't work with my carrier here.
any of you have some experience buying a cell phone in japan?
Thank you very much in advanced

I would advise buying against phones from Japan because most of them are tailored to their weird networks (general statement). I'd check what frequencies are used by your carrier and what frequencies the phone you're friend is going to buy supports. Japanese phones in general are usually made to operate in Japan with minimal support for extended use in other countries (e.g. you may get EDGE but that's it).
Thank you very much.
Looking on the web, I saw that there is a Sony store that sells international versions of their products. (And also a tax reduction )
Maybe I can find something there, looking at the webpage didn't find any cell phones.
I purchased a Oneplus One from a guy. Now I am faced with 2 problems.
The phone will read the sim card. For example if I throw a chatr sim card in it will say chatr on the top however, there will be no signal rendering no service.
the phone is not blacklisted or anything. IS there anyway to fix this.
I thought that all opo phones worked with all carriers (i.e Windmobile in canada) however I believe the opo i purchased was the chinese version. Is there any way to get this phone to work on wind if I can fix the first problem.
Any help is appreciated I am not very tech savy with this kind of stuff.
Thanks in advance.

The OnePlus One's Chinese model has those bands, but they are locked. You can use this guide to unlock them http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031. Good luck!
I get signals on chatr for 30 seconds and then they are gone,
I have this explanation mark where the bars are...
Please help
Hey guys this might be a weird one or very easy.
I bought my huawei ascend mate 7 in china in december 2014, has been working all good so far but while im in japan on holiday I havent been able to connect to the mobile network here at all.
I bought an "international sim" which is a sim service working through ecuador for some reason (dont ask lol)
and bought a data sim here in japan, both nano sims which ive entered the APN information for to no avail
My amaysim sim card from australia isnt working in the main sim slot either (although i didnt intend to use it so I havent activated roaming which is $8k per gb rofl)
When I go to the carrier list to try to choose a carrier the only ones that come up are chinese carriers like china mobile etc, im not sure if this has something to do with it since my phone has been working in australia using the auto select setting.
Any help would be much appreciated since ive lost my visa card and all sorts of horrid **** so im really pretty stuck at the moment.
I bought a oneplus 7 pro from someone through offerup
i had an old samsung j7 that had dual sim functionality that i need for work and productivity so when it came time for an upgrade i bought the oneplus as it was advertised as a dual sim phone by the guy who sold it to me.
at the time of purchase, i just opened the settings and saw that it had two sim settings (sim 1 and sim2) and i naturally assumed that it was a dual sim phone.
i also plugged my att sim and figured that it is unlocked. i also did a factory reset and there was no branding for any carrier when i started the device.
therefore i just assumed that this is the unlocked dual sim version.
however, once i got home and tried to put the two sim cards in it and i quickly realized that the sim tray can only fit one sim.
when i called oneplus support about this, they said the phone is designed as single sim and that it was a tmobile phone and thats about all the info they gave me.
i went to tmobile store and they confirmed the phone is unlocked and paid off but they wouldnt help
me any further with the dual sim functionality.
upon quick google search i found a dual sim tray for the phone and ordered it. it is arriving today. I am thinking that all i have to do is just install the new dual sim tray and have dual sims working.
however now that I am looking at the settings more clearly i see that the imei for both sim slot settings are the same.
i checked the firmware on the phone and it seems that guy who sold it to me installed the nonbranded firmware but i am not sure if it is still the tmobile branded firmware. Does the Tmobile firmware startup with the Tmobile logo? how can i know i am running the latest international firmware ?
are the imei numbers the same because it is still on the tmobile firmware?
the build number it reads is 9.5.11.GM21AA
Also, if i pop the two tmobile sims in it, will the device be blacklisted simce they both will have the same imei?

You are running international firmware.
The software is strange and just like the 6T it reports only one IMEID.
If you put in two SIMS they will have different IMEID.
Look in the forums for threads on T-Mobile converted to dual sim.
Thank you for the quick reply. The dual sim trey will arrive today so I will try it and report back.
Thank you.

Did the dual SIM tray worked for you? I am planning to do the same for OnePlus 7T..

If he is running a T-Mobile op7 that has been converted to International then he only has one IMEI. That same IMEI can be used in both Sim slots but you were wanting to be careful if you're using the same provider for example and an mvno that is on T-Mobile and then a second Sim that is also on T-Mobile although T-Mobile is one of the few that is pretty relaxed about duplicates. If you're on something like AT&T you'll want to pay a lot more attention.
If you are using two completely different Networks then you should not have an issue.
I know this works because I am using a T-Mobile version that was converted to International myself with a dual SIM tray.
If when the phone boots up you see that T-Mobile logo then you were still on the T-Mobile software. On the international version you'll see a little Android droid logo at the bottom and a OnePlus logo.

Hi,
New around here...
Any idea on how to unlock a T-mobile locked One Plus 7 Pro?
T-Mobile says I don't qualify for unlocking as I'm the 3rd owner and not having a T-Mobile account and SIM.
Any advice on this would be greatly appreciated as I'm going to inEurope for a while and need to insert local SIM cards for better rates.
Many thanks
Cris
As the title states, I have a T-Mobile OP 7 pro thats been converted to international. I already have the dual sim tray in it and have used it with a verizon sim in slot one and google fi in slot two. Only verizon required the imei to be attached to the sim. Google fi was pop it in and go.
Both lines worked perfectly with that set up.
I'm about to be using a verizon sim and a red pocket sim on att network in it. Thats going to require me to report the imei to redpocket to activate the sim sim same as verizon.
Will only haveing the one imei reported to both carriers be an issue? and is there a way to retrieve the second imei from the phone?+
I tried searching the forums and couldn't really find an answer.
As long as your 2 sims are on different networks for example one on AT&T and one on T-mobile you should be ok. The only time you might run into an issue is if you are using an mvno's sim that uses the same network as your primary. I'm doing that right now (also on a t-mobile op7 converted to international with dual sim tray) with T-mobile as my 2ndary and soon to be gone sim and Ultra Mobile as my Primary (which also uses t-mobile's network)......T-Mobile has been reported multiple times not to pay attention to this. Other networks may not be so forgiving. To answer your last questions...there IS no second imei to retrieve. The device was intended to be a single sim device so no 2nd one was allocated. The fact it works with the same imei in both is luck more than anything else.

Thanks for the reply, the second part is what I really wasn't sure of if the phone just hid the second IMEI or if it actually didn't have one.
I should be good then. I got the AT&T Redpocket sim and main will be Verizon.

Don't quote me on this, but from days with the 6T, I'm pretty sure it's just not reported in the software correctly but on the network side there are actually two different IMEID.
You should be able to (at least on Verizon) to log in and see the IMEID that is attached to a SIM.
Try the VZW sim in slot 1 and check online for the imei. Log out and switch the sim to slot 2 and check again. Hopefully you should see a different imei. Please let us know what you find out.

@blooddragon78 couple questions for you, as I also have OP7P that I bought from t-mo and switched to international:
- Were you able to use the sim tray that came with the phone? Or did you buy an aftermarket tray? I've heard mixed messages about the tray from t-mo having physical space for 2 sim cards.
- Did you have to unlock your phone to make use of the dual SIM functionality? Or in other words, are you still making device payments to t-mo?

I purchased a dual Sim tray from Amazon. The Sim tray from T-mobile will not fit 2 Sim cards. I'm a t-mobile tech expert so I do know for sure aside from owning one and doing it. For dual Sim to work the device does need to be unlocked as it only has one imei. If you didn't unlock before the conversion you will need to convert back to get the unlock app to be able to unlock.
There were a couple of threads on xda to get unlocked in the system but you still have to run the app. Not sure if they are active still.
If you need some help dm me.
Help with Op 7 Pro Sprint Unlocked version
Hello, I sent you a private message @blooddragon78, but Imma post here as well to see if anyone else can help me out, I'll greatly appreciate it. I came across this thread on being able to convert a T-mobile OP 7 Pro to the international version and enabling dual sim functionality. I was hoping to do the same as well, but I havent made the purchase yet in case it's not doable. Im currently looking at this OP7 Pro (Sprint version) that was factory unlocked and sold on Amazon (it's the OP 7 Pro sold at USD 499 by the Farmug Store) (if will be great if you guys can check and see the product to know what I mean exactly).
My question is what is the difference and meaning between "factory unlock/ phone unlocked" vs "sim unlocked" vs "unlocked bootloader?" I know this phone is unlocked for use on different carriers (and I live in Malaysia even), but how do I convert the phone to the international version so that I can receive updates from OnePlus directly (and not through the carrier)?
And how do I enable the dual sim functionality? Do I need to unlock the bootloader? Am I able to do that myself? Because I got confused as some people say unlocking the sim can only be done by the carrier, but Im not sure what is the difference of that with unlocking the bootloader.
In addition, say if Im able to convert it to the international version and get updates from OnePlus directly, dual sim functionality is enabled and such. Will updating the OS of the phone automatically (not doing it manually) lock the network/ brick the phone?

I don't k ow about dual sim.but converting International will allow Ota updates. If it's sim unlocked it should stay. Mine is still sim locked to t-mobile and I'm on internatti fimware
