Sim card not detected

Hey, I've had my Moto X Pure (XT1575) for a bit over a year now, and it's been great up until I updated it to 7.0 a week ago. It has been saying "No SIM card" and I have been unable to do much with it. Rebooting the phone will fix the issue and cell service will work for for about 5 minutes, then it disconnects again. Taking the sim card out and putting it back in will also fix it for about 5 minutes. I have cleaned the sim card and port, but that has not helped. I have also tried factory resetting the phone but the issue is still there, even during setup. The phone is running stock android with a locked bootloader. Any help would be greatly appreciated.

Replace the SIM card...

Check if another SIM card is working fine with the phone or not. If yes, then you need to follow what acejavelin has suggested above.

SIM card not detected

I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.
"8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi)"
You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.

I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.

And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.

I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.

Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.

I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.

Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.

could you detail how to do just that? Because I'm in Brazil and I have the same problem.

No SIM card - No service after Android 8.1 - Oreo Update

Hello everyone,
I am new to the forum and I would like to reach out to you guys to see if anybody can help me with an issue I am having with my Essential PH-1 phone after updating it to the latest version of Android. Basically the issue is that the system won't recognize my SIM card after the update, it just says "No SIM card - No service".
I've tried so many things already but haven't had any success, here is a list:
-> Rebooted several times.
-> Cleared cache.
-> Reset network settings.
-> Did a factory reset.
-> Rolled back to Android 7.1 (SIM card works) then updated it back to 8.1 (SIM stops working).
What's really funny though is that my girlfriend has the exact same phone, from the same carrier and she was able to update her phone to Android 8.1 without any problem. I also tested my SIM card on her phone and it works fine too.
Has anyone else experienced this issue? Any ideas on how to troubleshoot it?
Thanks,
Mike.

Where did you get the phones (hers and yours since you specify a diff)?
Did you try the unlock on this thread.
What carrier SIM are you using?

I haven't had that issue on this phone. When I previously encountered it (on the Pixel XL?) I powered my phone down, removed the SIM card, booted the phone up into Android with no SIM, powered back down, inserted the SIM and powered back up.
When you did the factory reset did you restore your phone from a Google Cloud backup? If you did you might have also restored the data that was causing your problem. Choosing the fresh start option instead of restoring from a backup is a much better idea.

Me too, with some added info

Might try having your girlfriend power cycle her phone.
I'm having the exact same issue with phone, Sprint service, except it did not manifest itself until a few days after the update when I power cycled the phone as the youtube app locked everything up.
I tried the advice above by the original poster, and the second poster, less the factory reset, to no avail.
Still looking for a fix. May revert to the prior version if I can figure out how to do that.

I am with a Canadian carrier called TELUS. I assume my phone in unlocked already because before the update I tested it with SIM cards from different carries and they all worked fine.

Yes, I did a fresh install, multiple times actually and it still didn't change anything.

Have you tried manually installing one the current builds from the manufacturer's website? That is what I plan to do next but haven't had the time yet...

I just did a SETTINGS/SYSTEM/RESET-OPTIONS/RESET-WIFI-MOBILE-BLUETOOTH.
It was fast, then I restarted. That worked for me!

This also happened to my wife's phone. It just started not recognizing the SIM card on Thursday the 19th. I tried a soft reset, a hard reset, removing and reinstalling the SIM card, updating the Profile and the PRL, all to no avail. I took it to the Sprint store, and they had no fix for it but gave me a code to dial ( *#*#72786#*#* ) that gives you some service for a short while. I finally had to file an insurance claim on it and had them send me out a new phone. I will not be updating to Oreo until they push out a fix for this...

Hey guys,
Just wanted to give you an update on my issue, not sure which one of these things helped but this is what I ended up doing and it seems to be working fine now:
-> Rolled back to Android 7.1
-> Reset Wi-Fi, mobile & bluetooth settings
-> Reset app preferences
-> Downloaded & install android 8.1 oreo update
-> Took out SIM card and restarted the phone
-> Connected to wi-fi
-> Inserted the SIM card and now it has been working fine

Glad to hear it's now working.

I have the same problem first with [ROM][8.1.0][trlte] Resurrection Remix 6.0.0 [20180425][OFFICIAL]. I took out the SIM card and inserted it back to the older Note II runing RR 5.8.5, it works!
Then I installed lineage-15.1-20180427-UNOFFICIAL-trlte.zip from https://basketbuild.com/devs/ripee/trlte [20180427 today], again, NO SIM CARD!
I noticed that both RR and Lineage Oreo 8.1 have the same problem at the first time system reboot: they both ask for inserting SIM card even though the SIM card was already inserted. I have never had such an issue in the countless ROM changes with earlier versions. Since current RR also use Lineage Oreo 8.1, I think the problem most likely comes from the Lineage Oreo 8.1.

I don't get it. Just realize I may be using a different phone (Galaxy Note 4). This method won't work.

I have a Motorola (Moto G5 Plus) and also had this problem. For me it occurred after 1st power down/up after update to Oreo 8.1 (from 8.0). Note that my phone has a dual sim (which I guess might be important here).
This is what worked for me
Settings → system → reset options → reset wifi, mobile, bluetooth.
Turn off the phone
remove sim
Start the phone.
Settings → network → SIM cards → enable Slot 1.
Then the screen with PIN-unlock was finally shown. I just needed to enter the PIN and it now works.
So thankfully didn't need to reset the system or even application settings. Just needed to enter my WiFi password again after all that.

Essential PH-1 SIM Card Problem
I discovered there is an information tag in the SIM Slot (it's got the texture of a mattress tag) the tag has FCC and Consumer Compliance Information printed on it. In my case, when I slid the SIM card into the SIM slot the tag got between the SIM Circuit and the SIM reader. I blew out the SIM Slot with canned air and the tag extended out the SIM slot. I tugged slightly on the tag. It's firmly attached at the top of the Sim slot. When I slid my SIM card back in I had a connection. I contacted Essential and they confirmed that the tag is there and said the tag shouldn't be a problem, but I think in many cases it might be. Essential said I could remove the tag if it interferes with the SIM connection.

I've been having this problem with the newest Android 10 update after about a hour of installation. I'm running twrp with stock Android tried resetting the connections, restarting the phone, and pulling the Sim tray and reinserting. The only thing the fixes the problem is wiping the phone and reinstalling. I'm currently back to running the last build. Anyone else having this problem?

Have to eject sim after a reboot for the phone to read it (Global Rom)

Hello everyone. After a lengthy battle, yesterday I finally was able to unlock my bootloader, flash a global rom (via MiFlash) to my Redmi Note 7 and lock the bootloader again using fastboot.
However I've encountered an issue that is very annoying. Every time the phone boots, it fails to read my Sim card, so I'm forced to eject it and then reinsert it in order for it to work properly. I use an SD card and I tend to reboot my phone once or twice a week, so you can get an idea of how much of an inconvenience this is.
I'm pretty sure this must be a software Issue because before the ROM change, I've never had an Issue with this. My phone model is M1901F7H and the rom is Miui global (10.3 Stable 10.3.5.0).
I need to mention that my current carrier (I got the phone from them) disables the hybrid sd card/sim slot and sells the phone with only one working sim slot and a custom ROM. After installing the global rom I noticed that now I can enable/disable the dual 4G connectivity for both sims toggle (it was greyed out before) however that is the only option regarding the dual sim settings that I can interact with and the second slot is still only usable for an Sdcard.
Currently I don't care much about the dual Sim feature, but it has crossed my mind that maybe my current Issue is related to this?
Anyways, thank you for taking your time to read this post and I apologize for the wall of text.
I would be very grateful if someone could help out.
Edit: I forgot to mention that one of my banking apps is now unusable as it crashes over and over again since I've installed the Global Rom. Don't know if it's related to the issue, but it worked just fine beforehand.

Check out my thread.
I'm also on 10.3.5 and think the issue is software related.
After reading your post, I'm thinking we may have something similar going on. My phone is working fine with no problems reading the SIM card after a factory reset a few days ago.
Hopefully you don't end up having the exact same problem I did.

I also have the same problem, I have to take out the SIM every time I reboot, I have the derpfest ROM and so far I have not been able to solve the error.

"No SIM card detected" & "No service"

Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!

Anyone?

I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.
https:// de.ifixit. com/Antworten/Ansehen/468864/Sim+Card+not+picking+up+mobile+network.+Possible+software+issue+(Oreo)
Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.

Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.

I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
