Hi guys,
My phone recently fell into the water and everything on the phone works except for the sim card case. the cell phone identifies the sim but it does not work and consequently the mobile data does not work. so I can't unlock the bootload to root the phone because I can't register the account and release the mi unlock status, do you have any idea how to get around this situation? I can't find a solution anywhere

Hello,
Recently, I had bought a used phone from someone, very nice Xperia RAY [st18i], but I didn't know that it's sim locked to T-mobile. I went to T-mobile centre and they said to me, that they can't do anything because phone is still under varranty, and If it is they can't unlock. So I made some research, found a solutions like buying a unlock code via weird sites, but the phone Is THAT hard sim locked that I even can not simply insert a unlock code., also bootloader is locked and can not be unlocked. [bootloader unlock: no].
My friend recommended me a solution of buying a "Turbo Sim", so I had bought one of them. It was simple, but there was a need to cut my SIM card a little to fit with a Turbo Sim in a sim container. But it doesn't matter, my xperia turned on and was not anymore asking to sim unlock code, I had just filled my PIN code and ... it wasn't working.. In a few seconds in a progress bar I had saw, that I had no signal,.. then it showed red "x" next to an empty signal bars and then the X dissapeared and again, no signal. Like a loop or something. I was confused, what to do.. I had tryed many times without any luck or success.. another day I had tryed again AND luckily, It was working!! This time it showed me no signal bars, then the red "X" next to a signal bar marks and then it turns to a full signal with a letter "R" next to signal bars [maybe roaming?].. but it was working!
I was glad.. but only for two days when I forgotten to charge my Ray and It went off, so I switched it again and AGAIN no luck! Signal bars dissapeared, - I am sure that the Turbo Sim still works, its not damaged or broken. A two weeks after this, I had tryed again to put my sim into my Ray, and it worked.. I don't know why and how, but it was working!... So I tryed to prevent discharging, It worked for a week or two, but my android messed a little bit and showed me weird things so I needed to reboot.. My signal bars dissapeared again and I am not able to connect to network again.
I am confused, what to do? Does anyone experienced something similar or same?
I had also downloaded an app LTE settings - as those turbo sims are only for GSM networks and there in my country we have WCDMA preferred networks, so I changed this the second time and it worked for a while.. Also tryed to switch on and off DNS server control. I had tryed many different roms just to be sure that It's not software related, I was not able to change kernel because of locked bootloader, I had tryed everything I found on internet without success.
Please, can somebody tell me what else to do? What can I try? Why It is working sometimes, and then for a weeks it's not and than It again works.. It is working always for unlimited time SINCE reboot, than I am not able to catch signal again.. How this can happen?
Every advice would be greatly appreciated!

Well, no-body replied, as it was expected -_- Since yesterday I solved the Isuue - For the others which will be searching for this kind of problem - An user "cadnyc" at youtube said that "T-mobile - some of the users on the forum recommended i plug that tmobile sim card back to a tmobile phone. let me reconnect to the cell towers. make a call and hang up. your tmobile is on its network now. eject the sim and plug it back to the iphone. im testing that right now."
THATS works perfectly! Regards
So parents managed to get a used tipo (single sim) from somewhere - but it end up being sim/network locked. The seller refunded money and didn't ask the phone back ether.
It doesn't seem to ask for the unlock pin - it just wont connect to the network.
So what options are there to actually get rid of the lock? at what level is the locks set ( its not firmware/rom level it seems - where else do they store it then?). I doubt the provided ordered phones with custom chips just for that.
Hi!
I have a Sasmgun Galaxy S4 (gt9500 I think...). A couple of months ago I got my unlock pin code from my carrier and unlocked it.
Yesterday the phone went down after the battery ran out. When I turned it back on , It complained saying that the Sim card was inserted but was not valid.
I tried that chip in another phone, all good.
I tried a working gsm chip on my phone, no good.
So, any chip I put in my phone shows the same message...
Also I call my carrier and asked if my cell or line was marked as lost or stolen, but nop. Everything was fine at their end.
Is my cell phone broken? What could I try?
Thanks!!!
samsung always have that issue... even galaxy s5,s6,s6 edge faces that problem... you dont need to active it again.. its a simple glitch.. try to do simple tricks by googling,youtubing...
hit thanks button if helped
I tried inserting it again.
I tried setting factory defaults.
I tried gsm chips from my own carrier and other carriers...
Nothing.
Hey there, everyone.
I've had my Z5 for over a year now, it's been running completely fine and have been happy with the phone. However last Wednesday my SIM card doesn't seem to work anymore. Let me rephrase that, the Z5 no longer reads the sim card. I have tested the SIM on two other phones ( one Locked to O2 and one Unlocked) and the SIM does work on both.
I've tried many things such as :
Searching Google + XDA, however the threads seem to be 2-3 years old.
Hard resetting the phone
Taking the SIM card out and gently cleaning it
Upgraded phone to 32.2.A.5.11
Downgraded the phone to 32.1.A.1.163
Tried to turn the Radio ON in the *#*#4636#*#* , didn't do anything, won't turn ON.
doing a factory reset did not work.
I am beginning to think the SIM card slot inside the phone is somehow damaged or moved position.
Any ideas? I'm stuck.
Guess it's an hardware problem, if so, you're screwed but if you have a warranty (seller or Sony) try to use it, I can't help you further sorry mate
9 months ago I switched providers from NTT docomo (where I still used a SIM lock free iPhone) to SoftBank (where I got a new Pixel 3, and first time in many years that I got a phone + SIM).
But like how the whole nature of planned obsolence works, gradually going from best phone ever to falling apart to boiling my blood.
First the USB-C port of my phone stopped working (so I am now forced to use wireless charging and SFTP on a local network), then the FeliCa chip started becoming instable (which is fine, I can still switch back to a dedicated SUICA card where the FeliCa chip works for a decade), then I was forced to set up a finger print to use Google services (later on turned out to be just a policy issue in Google Apps, I already fixed that) which only makes my phone more insecure (random unlocking if accidentally unlocking the phone within 5 seconds or when the scanner touches the skin of my lag through my pants), but after I turned off finger print authentication my phone started to randomly unlock itself whenever I get extreme weather warnings (and since it's summer, I'm getting multiple times every day).
So I was looking for switching to another phone, and I bought a SoftBank branded Digno flip phone from Amazon, and my SIM card didn't work.
I went to SoftBank have them take a look, the guy was searching using my IMEI for 30 minutes only to tell me that the Digno problem is a very rare case and that Aquos flip phone doesn't have this problem because Digno is too old (released before 2015).
So I bought the Aquos flip phone that he recommended me, but again my SIM card didn't work.
I started to question it, and put my SIM card into my SIM free iPhone: didn't work.
Then I put it in an Aquos smartphone which I bought specifically as a SIM free phone: didn't work.
I went to SoftBank again (this time to a different store because I didn't have much time) and explained the situation.
The guy then told me that I must have my phone registered at SoftBank for the SIM to work.
Then I asked how I can do that, he said that I must purchase a phone via SoftBank instead of Amazon, or otherwise let a totally different SIM card get issued.
By this I'm not complaining or asking to hack the system, I only want to ask if anyone knows about such a tactic? Did anyone experience it too (in Japan or overseas)? And is it normal for a phone provider to lock your SIM card to a specific phone?
And while we're at it: if I flash my phone with a custom ROM, will this render my phone to be unusable with this SIM card as well?
Looks like you are down with a string of strange events and bad luck.
Softbank seems to be a d*ck and I would change a provider if I am you. It is illegal in my country, malaysia, to lock devices to network. But you can easily just register your phone imei to Softbank if you really like the coverage they provide.
As for phones I can't comment on that as I never used pixel, aquos or any of the phones you mentioned but the fingerprint able to unlock by touching your legs through your pants sounds like a hardware failure and I would bring the phone in for repair.

In my experience Docomo works really well within the Yamanote area of Tokyo, but I cannot afford living there and my work is just outside of that area.
And I already had home internet from SoftBank, which were the 2 reasons why I went with SoftBank, plus its coverage works really well (even when I go to a mountain village north from Sapporo, which I did yesterday, I still have really good coverage).
Their SIM only plans were also really good, I really feel like an idiot that I took a SIM + phone set this time…
My friends (I have them despite my username) also recommended me to go with au, but I didn't like what they covered (can't remember what exactly, but I remember it was somewhere among those lines).
But would be nice if our politicians would make this illegal too, once big companies obtain too much power, it's never going to be enough for them.
Edit:
I only want to add that the only time I had a bad coverage with SoftBank was when watching fireworks at the Edo river, but I'm not sure whether it's because I was near a big river or because the part of the river has a 3 point prefectural border (between Tokyo, Chiba, and Saitama).

It isn't a matter of "locking the device to the SIM", it is a matter of the device being registered on the service providers network using the device's IMEI number and the SIM card number being registered as being used with that device, both of these numbers must be registered together in your service account, that is how the network recognizes your device and how it knows to send service via that SIM to your device. When you switch to another device, the new device must be registered on the network and the SIM must be registered as being used with that device.
It's similar to registering your car and registering a license plate on that car. The car is registered to identify it as your car and the license plate is registered to identify that the license plate is for your car and not someone else's.

If it's true, then I'll try it out.
Somehow confusing if employees of the same ISP working at different branch stores tell me totally different things. (´；ω；｀)
