[Q] Very Weird Issue - LG Optimus G Pro

My wife and I have an ATT OGP. Starting yesterday, she was not able to get any kind of connection on her phone. The phone would not register on a network or anything. I put my SIM in her phone and everything was fine, so we assumed her SIM was bad. She went to the store this morning and they found that her SIM worked fine in other OGPs in the store as well as the guy that was helping her. Their test SIMS and several other SIMS they used worked in her phone. Long story short, her SIM will work in it seems any other phone but her OGP, and everyone's SIM will work just fine in her phone. Why would the OGP not take that specific SIM, but every other phone will?
They are replacing it, but I was just wandering if anyone has seen anything like this.

That's a first of hearing that!

Cannot connect to wind!?

Hey guys, I have a Galaxy S3 from Wind (T999V) It worked perfectly fine for over a year. After the warranty was up, I decided to root since I didn't really have much to lose. I flashed everything from, CM to Illuzions ROM. Everything worked great. One night I was on the phone with my girlfriend, we got off around 12. I put my phone on charge and then the next morning I woke up around 6:30, checked my phone and all was still good. Then after taking my dog for a walk, I checked once again at 7:30, and I was not connected to wind anymore. I turned airplane on and off, hard resets, unroot and back to stock. I have actually tried everything. Spent hours upon hours with wind tech support, and they even gave me a new sim. Went to a warranty center to pick up the sim and even with the new sim my phone wouldn't work. While there, I asked if they could try the sim in a different phone, and it worked in the other phone, so I'm pretty much certain its a hardware issue now, though it worked perfect for over a year,
Can someone please help me, PLEASE?!?!?!?!??!?!?!!?!!?!?!?!?!?!?!?!?!???!!??!!??!!??!?!?!?!?!?!?!
P.S. Already tried to manually select a network, All it will find is Wind Away. I put in my friends SIM from bell and it got bars, connected to the network, just wouldnt let me place calls because it is locked to wind.
Sounds more like an account issue to me. Find someone with a wind phone, and try their SIM in your phone. The way it sounds to me after testing with the Rogers SIM, is that the device is fine. If it were hardware your friends SIM would have done nothing more than yours.

Yea, but when I went to the wind store to get my new SIM, they tested it out on another device so I know the SIM is working, so wouldn't testing his SIM on mine be the same as testing my SIM on any other wind phone?
No idea. All I know is you mentioned that when you tried a Rogers SIM it seemed like it worked, or would if unlocked. Only way to know is to try another SIM on your phone. Could be an account issue. But if it appeared to work as expected with his SIM, that tells me it's probably not hardware.
Maybe a wind tower is having problems....

[Q] Unable to detect sim card

I bought my note 4 on launch day. Ever since then I've had an "unable to detect sim card please restart phone" error. At first it only showed up once every few days, but now it is getting more and more frequent and is happening multiple times a day. After reading starting the phone works fine for a while. I've done everything I can think of (pulling the battery, pulling and re inserting the sim, cleaning the sim), but nothing helps. Anyone else having this issue, or know of a solution? Thank you.

I am having the same issue. Not sure of a fix yet but it is getting more and more frequent which worries me.
Same here. :sadface:
Same here! Anybody contact Samsung or Sprint about it?
Same here!!!
Just got my note 4 from Amazon.com. I had been reading about the lte to 3g call drop issue, and someone posted using there sim the card from the phone they were replacing fix this issue. So I put mine in from my s4 before i even turn it on for the first time. The phone worked, but was unable to connet to the 4g (lte / spark ) network. 3g worked fine. I got the message you all are getting (no sim, restart device....). It would happen like every 10 minutes. Once I put the sim that came with the phone in , all my problems went away. Long story short, you need another sim card.
I just called sprint and they are sending me another SIM card. It happens from time to time, but they did tell me if it continues, I can get it replaced for no charge.

This happened after my sim card swap. It would say "network did not respond in time" then "could not detect sim" then phone would reboot. It did it three different times. Then connection became stable and has not done it again. Not sure if these issues are the same as whats happening here. Just posting my experiences.
I actually bought 2 N910P. I planned on making a little extra money by selling 1 of them, but didn't count on the N910P being so easy to get, so I've held onto the other one for a back up until I found a ROM that I wanted to run on it. Well, I found a awesome ROM & booted up my 2nd N910P & got the message you have all mentioned. I thought it was strange, so I rebooted & got the same message again. After doing this a few times, I thought why not take my SIM card from the 1st N910P & put it in the 2nd N910P. I still got the same message after doing this, so I swapped them back before it messed up my primary SIM card. @Yoshi1221, please keep me/us updated if the new SIM card works for you. Has anybody else got a new SIM card? Also, after installing the 2nd ROM that I was trying out, the fingerprint scanner stopped working. I went back to stock & it still doesn't work, so I made sure that I did a full NANDROID backup on my 2nd N910P in hopes that once I get it working & the fingerprint scanner stops working, I can go back. Anyone else had this trouble?
Edit: I tried to activate my new GN4, but the DEC & HEX numbers were not recoginzed by Sprint.com. So I went into chat & they informed me that it had been turned over to technical support & to contact them again after 24 hours, so we'll see where it goes from there.
Update: Chatted with Sprint & the lady activated the SIM card after giving her the number. Hope this will help out. Just go to Sprint.com & click on the chat button.
Looks like new SIM card is working, but just got it today, seriously had to give up an arm and leg in order for sprint to send me one, but so far it looks like it is working, but just got it today, lol

Cool, glad it work out for you.
Also found out from a supervisor in the U.S that sprint is now selling GSM phones now. If you take out the SIM card and only receive 3G, you have a GSM phone, if you take out the SIM card and have spark/LTE, you have a CDMA phone

I had this problem. Sprint sent me a new sim. Fixed the problem for a few weeks but it has returned. Anyone ever get this figured out?
Sim card not found
I had forgetten about this error. Saw that someone suggested a piece of paper between the sim and case cover. I had this happen with a phone I got off a forum. Sent it back and got a replacement. The paper, no matter how thin or thick may or maynot work, and only for a short time. Changing the sim might not work either. You may just need a new phone. I went through all with a s4. Now my note 4 is doing it. I thought it was my recently deceased (July 4) mother was messing with me. One more errand to add to my list for today.
same here?
help plz

Calls and text not working on AT&T?

Hey guys so I woke up this morning and noticed that I can't make calls or send texts. I can't even run those codes through my dialer to check on my data. Which is weird since my data is working perfectly fine.
At first I thought it was my apn settings that got all wonky but I put my Sim in my Optimus G Pro which is complete stock and I get the same results. It's currently Sunday and the AT&T store is closed. Do you guy's think it's a problem on their end or would it possibly be my Sim card that might have gotten damaged? I almost never took my Sim card out, it's stayed in my g3 for most of its life. I haven't taken it out for maybe 5 months now and everything was working perfectly yesterday.
I would just like to hear your opinions on this please.
Edit: All working now, guess it was a tower issue.

Faulty SIM reader! Anyone else? Getting phone replaced

Got my 16GB Ice Nexus 5x today. Took my att nano sim out of my nexus 6 and put it in 5x. Phone said no sim detected. Tried about 20 more times taking it out putting back in, nothing. Tried my old tmobile sim, nothing. Went to att store got a brand new nano. Still nothing. Working on getting it replaced now. Wont detect anyyyyyy sim. ugggggg
Maybe you your 5x needs to be added to their database? Not sure but I had a similar issue with my N5 with Sprint when they first released and bought direct from Google
Sent from my Nexus 5X using Tapatalk
A friend posted that he needs to buy a new SIM for his 5X because the SIM from his N6 is the same size but electronically different. (His is a Project Fi SIM if that matters.)
I'm skeptical about that but it seems clear that you are also having an issue using the SIM from an N6. I'm wondering if the SIM from my N5 is going to work.
this made me cut my att sim a few minutes ago from my N5. The cutter worked fine. http://tinyurl.com/o39so98
tested in N5X and worked fine, H to LTE hand off was about the same as N5, I was worried about that, but it's all good.
I put it back into the N5. But I had to use the old surround from att sim instead of the adapter that comes with that cutter.
There's a small difference, and for sure you can definitely f this up if not careful.
My Ting/GSM (The carrier who must not be named is T-Mobile ) Sim worked without difficulty. It was die cut for the smaller size. I kept the part I popped it out of just in case.
It took a surprisingly long time to get on the network. I kept checking and it showed no phone number for what seemed like a long time. I started looking into the Ting web pages and started to run through the process of activating a phone, thinking I needed to do that. At that point when I went to the settings to get the IMEI I saw that it had the phone number and calling was working. It was probably over an hour.
i have this problem too actually. After trying maybe 10 times it worked, but it would keep saying no sim card, and it would IMMEDIATELY work on my MXPE. That being said, i probably need a new sim card. A coworkers SIM card worked without issue.

Rooted P3aXL, I reset wifi/mobile/bluetooth, now no LTE and APN won't stay!!

Hey all - long story short, my upload speeds today topped out at .13MB/s, so in desperation I called Verizon, who did some resetting on their end and talked me into resetting my wifi/mobile/bluetooth, which is in settings/system/reset options.
Since then, I've had no 4G and nothing has brought it back. Just did a factory reset and STILL nothing!!
Interestingly, when I open up my APNs, there's only the Verizon one, but it's never selected - even if I select it, still no LTE, and after a reboot it's unselected again. Also with this phone seems I can't edit or add APNs.
I am *absolutely* out of options - really figured the factory reset would take care of it!! I would be most grateful for any help you can give! Thanks in advance - can't tell you how much I appreciate it.
So fun story - on a whim I put the SIM of another 4G phone in, and works like a CHARM. So somehow resetting the wifi/mobile/bluetooth fried the SIM! I think I got one for free at the Verizon store last time this happened, so I'll head there first thing tomorrow!

So you put the SIM in another phone and it worked fine? I am pretty sure you just proved the SIM is fine and the problem is in the device, or it's configuration...
I have been through a dozen phone on one SIM, never had a SIM fail and I have only replaced it when changing carriers. Odd that this happened to you, and happened at least once before...
Nope, I put another phone's SIM into my phone

But you put your original SIM into another phone and it worked fine in another device? Or am I misunderstanding?
I am not trying to argue here, just understand...
No, I never did - I didn't try my SIM in another phones, but I did take the SIM out of my girlfriend's phone and put it into mine, which then immediately got a 4G signal, so I knew the SIM was the issue. Ran to the Verizon store for a new one, and the guy there said "whoa, that's a really old SIM" and I had to remind him what a SIM cutter was - I've had it a while
