First of all, I don't know if this is the right place to post this, so do tell me if it's not.
I switched phones recently from an LG G3 to this one and so I had to ask my provider for a smaller SIM card in order to fit the phone's slot.
After switching phones and using the new card, I noticed that the messages people sent me had a considerable delay in being received, be it 10 minutes, some hours or sometimes even a full day (according to the details displayed by my messaging app)
I tested my SIM card on my old phone to see if the problem was fixed or not and I didn't notice any delay there, so I assumed it was the new phone and flashed LineageOS 14.1 to see if it would fix the problem. I didn't get any delay during the first day.
Today, however, a message got delayed by 10 minutes and so I have no idea if the problem was fixed or not.
Could anyone please help me understand what the issue might be and how to fix it?
Thanks in advance.
EDIT: I think I fixed it, if anyone's having the same problem.
Disable VoLTE and change the system select in the SIM options to Home only, that's what did it for me.
Please close this thread.
I didn't have the same issue
Maybe in Miui you have misconfigured the option security-permissions-sms-contacts ....
Solution to delayed messages with Miui 10 os.
I see some of you are having problems with delayed sms. What I will recommend to do is not a ?% fix, yet it has worked for me as a user of Miui 10.
1. Go to settings and select system apps under app settings.
2. Select messaging and scroll down to additional settings. You will see 'Short Message Service Center' select it.
3. The number provided in this field is actually your network provider service center number, which is what we will now replace. You put in your area code first with your cell number replacing the default 'service center number' founded. Problem solved.
This was my fix, having to deal with two step verifications being delayed, on my xiaomi redmi plus 5 which was annoying.

I've recently bought a Lenovo K860 from Bangalore, India. There were two issue.
1. After every SMS our service provider (TATA Docomo, India) sends a pop up message stating the charges for your last call/message. This message comes up with gibberish letters, completely UN-readable. I've called up Lenovo Customer Service and explained the problem to them. Now they are coming up with a patch to fix this issue.
2. Trying to send TEXT messages to another user is becoming a pain. When I try sending a text message, sometimes it just displays "Sending" and had to wait for a long time before it fails to send. When I try again to resend it, it eventually gets sent. Now this is happening quite frequent. I didn't face this problem when I had used the same sim card on any other phone.
Question: Is it a network problem?
Or is there a problem with my OS?
My guess would be.. it cannot be a network issue since I've tried using the same service provider on another phone. I think it would either be a software (OS) issue or settings. If someone can help me sort this out, I'd really be grateful and very much appreciated.
Can someone help/suggest?

Any other help?

Update: Took the phone to a Service Center a week back, the issue was immediately escalated to the higher up. Got a new Software Update yesterday, now the phone is working like a charm.
I somehow do not regret buying this phone. This is a trivial issue. Now no issues whatsoever. PERFECTO!!!

No other issues. Thank you. But one Amazing phone this K860 is. Just had a trivial issue.
Hi everyone,
I recently bought the phone from T-Dimension and it's having some issues and I was wondering if anyone could help me out or if they've run into something similar. The issue is I can't seem to send/receive any calls and I can't send/receive any texts. The bizarre thing is it works for the first 45 seconds when I reboot but then locks me out straight after that. The phone is issued from Hong Kong and had Color OS on it but I flashed CyanogenMod onto it, here's some more information.
- The phone is connected to Amaysim, which runs of the Optus network I believe, so it's connected onto the mobile network just fine.
- The Micro-SIM card I'm using is brand new, it's put in correctly into the slot, meaning upside down facing towards the bottom of the phone, so that's fine.
- I've tested the SIM with other phones and it works perfectly fine.
- When it locks me after 45 seconds, it fluctuates from saying, "Call Not Sent" to just it being stuck on the dialling screen.
- After being locked out, I can't receive any calls either, I've tried calling the phone but nothing shows up.
- After being locked out, I can't receive any messages either, when I try to send a message it just stays stuck in sending, and if I restart the phone, it just says the text failed.
- I've contacted Amaysim Help Desk, and they say my problems lie with the phone being locked, and I'll have to contact the manufacturer to sort it out.
- I've also contacted my supplier, who seems to have trouble finding out the issue.
- APN settings are set correctly with my mobile carrier.
- Already done a factory reset, didn't fix the issue.
- Put the preferred network type to 3G under Mobile Network settings.
- I flashed CyanogenMod 11S using this tutorial from youtube, /watch?v=QDKOEtN9pbo and downloaded the cm-11.0-XNPH22R-bacon-signed.zip file.
Please can anyone help me with issue, sorry for long wall of text, I really want this phone to work!
Cheers,
You probably should flash another modem & then try.Here

Hey there fellow Aussie. See link provided by other member, it should fix you up.
Transmitted via Bacon
That modem actually proved to be worse for me.. Before I didnt have stable 3G connection.. that modem made my 4G connection worse too. The best, and most stable modem I have found thus far is in the latest nightlies. It is still very very very weak when it comes to 3G connectivity but its better than everything else I have tried. And believe me, I have tried pretty much every rom there is on this forum including XNPH22R, XNPH25R, MahdiRom, CyanHacker, and All the nightlys.
The only one I havent tried is Color OS because I am afraid it will lock my bootloader again.
Hello everyone,
Let me submit here a problem that rots me life:I have a Xiaomi Mi4i and despite the updated 5.9.16, I have a problem with pop-up that appears every 30 seconds indicating the "Managed Roaming (Sub1) ....
sorry I'm not allowed to post a screenshot on this forum but you can see it folowing this link ( by replacing dashes by what is missing): h--p://w-w.hostingpics.net/viewer.php?id=168394Screenshot20150920200955.png
It is a message that tells you that your network operator you manually select from one of two sim cards is not captured and invites you to choose another manually or set to automatic mode.I'm forced to choose between cancel or ok to make disappear this message that highlights on the screen and causing interference on my running applications. Since I am in the border area, and that according to the side where I am of the border, there is always one of the two SIM cards no longer picks up the signal. I can not afford to let the sim cards in the automatic mode because roaming is too expensive and it's also the reason that made me choose this dual sim. Suddenly, the pop-up turns on the screen every 15 sercondes and it rots me, every time I pick up the phone I need to click cancel and it turns round. It annoys me so much that if I do not find a solution I'll have to buy another phone ... It's so stupid but I have no solution, I had the same problem with a MI2 2 years ago and I had to put it in a drawer ... I thought that since that time, problem had been resolved. But I can not be the one to meet this concern all the same! I tried everything without success.
I specify that I tried all possible versions miui and the problem is the same.
I think it is imperative that developers delete this message pop-up screen and simply leave the choice to seek a network from the notifications bar !!! I have a bottle thrown into the sea via the application "BUG" pending .. If someone has another solution waiting for the grace of an update includes a fix, I'd be eternally grateful to him ...
Please, can someone help me? I do not know what to do, this problem makes my phone unusable!
Yep, happens to me too. There are some weird bugs in MIUI.

Yes what a pity, I should have stayed on a standard model because Miui is for those who love having problems ....
This fuuccccck pop up....lost signal and then pop up simultaneous...how to delete forever this pop up
It's 2018 and the problem still here, but there's good news. I know it's an old thread, but this provides a possible solution. On Android 8, on the Available Networks screen, you can tap Choose Automatically and the problem stops, even if you are unable to connect to a network. Might also work for other android versions.
I have xiaomi a1 and still same problem.
If I put on automatic, phone will change to roaming network and I dont want that!
Im still on stock rom. If I take some custom rom will I have same problem.
Anybody know?????
My wife and I both have OP6's. I've run OB since the beginning, she runs stable. Since not long after my wife received her device, she began not receiving SMS messages nearly every morning until she restarted the phone. Data and sending sms work fine. She contacted her service provider (cricket - an at&t MVNO) and they reset something on their end but to no avail.
A few weeks ago I had to send my phone in to an OP service center to have the screen replaced. When I received it back, I began experiencing the same issue a few weeks later. I'm on AT&T directly, albeit through their prepaid program.
No idea what's causing this, or even if it's hardware or software related. I'm wondering if maybe it's hardware and OP exchanged my device instead of repairing the same one, as the turnaround time was lightning quick.
Anyone else have this issue or any ideas to look in to?

So what is the problems exactly? Delayed SMS, no SMS, sending or receiving?
1. Go through settings -> system -> recent app management and check if it's not deep clean
2. Go to battery settings -> battery optimization and chose the app you need and click don't optimize.
These are the simple solutions that might stop you from getting messages. Other solution could also be battery saver turned on since it limits background apps

Can send but not receive. "Pending" messages still are not received after reboot.

I turned off optimization for Textra (which we both use) but I've never had issues with it before. Recents behavior was normal clear, but I'm not a normal recents clearer like some people.
Heyy Guys,
I'm creating this post after facing terrible issues and embarrassing situations because I can't send sms from my Poco X3. It's a new phone and barely a month old, and I've tried uninstalling updates for career services app, Google messages app rebooting the phone and what not!! Still rarely on some lucky day I can send sms and rest of the time I can't..!! It's really frustrating when you need to do online payment and need to send a verification text..!
Thankfully @Dandito from XDA forum replied to a thread for another poco phone and he said that
"The problem is existing only when the VOLTE service is enabled. Try to move on 3G only or just stop Volte under 4G and it will be ok. Unfortunately Xiaomi are using some specific technology for volte sms sending and the your network provider does not support it. The phone is trying to send SMS through SS7 instead of SIP protocol when VoLTE is enabled. I'm trying to find a hidden menu where I can eventually switch or choose a protocol but without success."
This fix worked for me miraculously therefore kudos to him for finding this..!! Respect+++++++ for this guy!!!
Now if anyone can find a fix for using volte and sending sms at the same time then please please do reply to this thread!! I'm trying my best to find a solution but your help would be great too!!
I did some tests and I have new findings..! Please hear me out!
I can't send sms from my sim in poco x3 when volte is on!!! And when it's off then also rarely it works... sometimes I can't receive any otp on this phone!!
Do note that this idea 4g sim works perfectly and can send and receive sms in my realme 1 with volte on !
Now other sim cards work perfectly in my poco x3!! I tried everyones sim in my house and it worked fine..!!
Now if I complain to idea people then they'll say that it works well on another phone so please complain to phone company..!
And if I go to poco then they'll say that change your simcard as other sim works fine!!!
I'm genuinely tired and frustrated and I get heavy embarrassed while making online payments and imp work stuff!! Sending and receiving SMS is fundamental and necessary and this is barely a month old device!!!
Guys any suggestions would be heavily appreciated
I use Volte on both my SIMS and send SMS normally. Jio and Vi (Vodafone Idea).

Regular stock ROM that came with my phone.
MIUI 12.0.8. Are you sure this is an actual problem that exists or something wrong particularly with your device. I haven't heard of anyone having this problem of being unable to send SMS while on VoLTE. I have multiple devices and multiple providers and they work fine on all of them too.

Well since your steps of troubleshooting have failed to reach a singular conclusion, I have a feeling that something got messed up during original pairing of your phone and that particular SIM card.
One test says your phone is fine because other SIMS do their job just fine.
Other test says your SIM is fine because if you put it in another phone and they do their job fine.
Which leads me to one conclusion. There is some kind of pairing glitch with that particular SIM and your phone.
I have only a few suggestions. And you might want to do them ANYWAY.
1: Go to Idea (now Vi) showroom, ask for a replacement SIM. You don't need to explain to them why you need it. Just say it doesn't work or it's scratched. Don't tell them about it working on other phones etc. New SIM costs around 30 - 100 depending if they follow official process or want money in their pockets. Activates within 4 hours with the same plan but OTP will not work for 24 hours.
2: In the meanwhile or if you can't get a replacement SIM use Isopropyl alcohol and clean the current SIM you have.
3: Factory reset your phone WITHOUT your SIM inside and set it up fully without the SIM. (Make sure you remove your Google Account before the Factory Reset.)
4: Last if all else fails. Take your phone to Mi Service Center and make up some stupid reason and ask them to flash your phone. Tell them you have already Factory Reset (3 times 4 times etc) and that it didn't work. By default they automatically will jump to Flashing it, no questions asked.
They will also flash a version of MIUI around 1 or 2 versions behind current version.
All the best and please update after trying these steps.

Dayyyyuuummmm...!! I'll definitely try that Man...!! Thanks a lot for those suggestions...!! Will surely update here in detail once the issue is resolved..!
For reference, I faced a similar issue with my Idea SIM after I got it replaced once. I could NOT absolutely make any calls on 3G.
Everyone's SIM in my phone the calls worked fine, my SIM in others phones ALSO worked fine for making calls on 3G. But there was something particularly wrong with this CURRENT SIM and my PHONE together.
I got a new SIM for 30/-
It got activated within 20 minutes.
Everything works fine now.
(No needed to Factory Reset)
It's some pairing miscommunication that occurs at the time of activation and that error somehow stays with the card and phone combined. I'm not an expert on this so I could be wrong.
Technology is weird.

Also one wierd little detail I'd like to share..! As we have Google apps in dialer and messages....and this is for messages app in particular..! Whenever I receivet these flash message or pop-ups of remaining balance or recharge expiry days left after every phone call or sms..... then in my current sim card it comes as a full page banner anything that's currently running will be interrupted unless I cancel that persistent flash message and then continue my work...like full opaque page no transparent or translucent or anything!! And if I put other sim cards then it'll literally show up in the bottom without any interruption!! Just a small place at the bottom of screen...!!! Such wierd stuff happens man! I still can't figure out the reason for that!! Both sim of same company and same recharge plans...still they have completely different behaviour and quality.... technology is genuinely wierd

Same issue with my new Vi SIM. (Didn't happen when it was iDea SIM on the same phone). I have tried every possible thing to block this behavior including contacting my service provider to let them know I don't need the messages cause I'm on Unlimited pack.
This is more to do an issue with the way Vi sends those messages as a priority/emergency and not as a regular USSD message.

I'm glad to be of help. I knew the issue was with that particular SIM pairing. Here's some bonus information for you.
Type *199# in VI
Then send 2
Then send 2
Then send 4
This will stop the Data Notification.
If I have genuinely helped you please give all the comments I've made that helped you a THUMBS UP.
That would really be appreciated on XDA
