Hi all,
yesterday out of nowhere my moto g LTE lost all signal and instead is displaying "NO SERVICE". Iv'e tried reboot, soft reset, factory reset, removing and re-inserting the sim card, putting in another sim - nothing. the issue is not with the sim itself as I now have it in another device I have and everything is working great. anything I can do about this? tried searching for a solution but didn't find anything I didn't try already... the phone is quite new( ~7 months old) but I bought it while abroad and I'm not sure about warranty and such...
any help would be GREATLY appreciated
It normally does that when the phones been blocked by your provider.
You should ring them and double check it with them.
If not may be a dodgy antenna
I checked with my cell provider, and then re-checked my SIM with another device. everything was working perfectly. so the issue is indeed with the device =/ is there anything I can do about it? =/
I have the exact same problem, also tried factory reset and put on the stock rom, is it possible to change for a new antenna to find out if this is the real problem?

Hi everyone, I have run into an issue with my phone not recognizing my SIM card. Here's what happened:
I had been experiencing weak GPS issues with my phone, and I searched online. A lot of people recommended removing the screws on the back plate and putting them back in. I guess sometimes the screws get loose and then the GPS radio doesn't function as well. So I took all the screws out and put them back in. I rebooted the phone, and the GPS worked much better. Then I realized I was in roaming. No 4g, no 3g, no regular cell service. The phone says "No SIM Card - No Service".
I have checked the settings and I still have an IMEI. I have had to Odin back to stock a couple of times, but the fact that I have an IMEI still makes me think that that won't help in this case.
Could I have dislodged the SIM card connection somehow? Does anyone have any idea what to do? Is this a hardware fix I need to do?
Any help would be appreciated. Thanks!
Just a suggestion on something to check, no idea if this will fix it but it's worth looking at.
I recommend that you check the CDMA subscription to make sure that "RUIM/SIM" is selected and not "NV"
I am running an AOSP rom, to check this setting you'd go to System Settings -> Wireless & Networks -> More... -> Mobile Networks -> CDMA subscription

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
I bought a new OPO,
When i opened the box it looked so cool! i booted the device and then saw the beautiful screen. But then the horror started.
I opened the sim slot. put in my Nanosim and closed it. It asked for my pincode... When i enter my pincode it just went to the mainscreen and gave NO signal. Then 5 seconds later it asked me to enter the pincode again....
Over and over and over. So i thought..... My nanosim is bricked! i went to my provider and gotten myself a NEW MICROSIM. I plugged it into the phone and 1 2 3 guess what..... Same problem. i kept trying and trying watched 50 videos on how to plug in your simcard correctly...Still the same problem. I tried my dads sim, my moms sim (different carrier)....SAME PROBLEM.
Then i unlocked the bootloader, rooted it and flashed Oxygen on it. Guess what.... Same problem. Flashed back to CM11. Same problem.
I think its either an antenna problem, or a simreader problem. Anyone have any idea what i could do and what this issue might be? Also i received the phone in this state. The day itself i already contacted customer support with my complaint. So i assume this is warranty right?..
Heres a small video i made for the support about my problem.

Thanks lads
I assume you put the sim correctly as you stated, that is the metal contacts facing downwards. Also, have you tried resetting the phone from the setting menu? Another option would be to dial *#*#4636#*#* and choise the correct network option from the phone menu.
Well, what should i set the network to typing in that *#*#4636#*#*?
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.
I purchased a used US version Rog Phone 5 recently through an online seller. When receiving the phone, I gave it a good once over and powered it on and tested wifi and such and everything seemed to be in good working order. I then rooted the phone and set most of stuff up. After inserting my sim card, I noticed the cell reception was not that great. I suffered through for a couple of days but was missing calls and texts like crazy. I was constantly dropping reception entirely in areas where I have very good signal with other phones. The phone is essentially useless now. I tried several factory resets, flashed back to the non-rooted boot image, and then flashed to an older firmware with no improvements to signal. I can't imagine the reception issue is in any way related to the rooting process, but I'm throwing this out there just in case anyone has seen anything similar in the past.
A few things to note:
I am on AT&T
The APN is definitively configured correctly
I could have returned the phone to the online seller for a refund prior to unlocking the bootloader, but did not insert a sim before rooting, so I have no idea whether the issue was present from purchase or not. Lesson learned, I suppose... do a more thoroughly inspection before doing anything that will void a warranty or refund agreement.
I have tried the same sim in two other phones with no issues.
Everything else about the phone seems to work perfectly, only poor reception.
I had the phone up to approximately 30 miles from my house with no change, so it isn't limited to a specific tower.
Does anyone have any ideas? If I don't come up with anything I will be posting it on ebay as "not working - for parts only" so I will try about anything at this point.
Sim recognition issue
Owned the phone for about a month now. Phone was working perfectly fine for the majority of this time. I use 2 different sims and they were both working smoothly until recently. A few days ago, I woke up and the phone wouldn't recognize the Sim...

sim card problem
just all of sudden it became invalid sim try multiple time reset or clear data cache sim toolkit original sim to other phone is working other sim to original phone is working other sim to other phone is working anyone face the same problem...

Sounds like they pawned the issue off on you, but it should still be under warranty to have it repaired. When you contact Asus, don't mention unlocking the bootloader. Stick to the hardware concerns.
I have looked over both of those threads, but it seems to be a different issue. My sim is recognized fine, its just the signal strength that appears to be extremely low. Even when the phone has no service at all, it still recognizes the AT&T sim is present.

Yes, it is not the same issue, but it appears to be a similar issue. The important detail being that both required a motherboard replacement.
