Issue with receiving text or making a call on Mi 9T - Redmi K20 / Xiaomi Mi 9T Questions & Answers

This happens every few months, my phone Mi 9T just stops receiving messages out of the blue. Using google message app, I am able to send message but if the recipient replies i will not receive. May never even receive till weeks later. I have moved the sim card into a different phone and it can receive and send with no issues so I don't think its my services.
After swapping sim cards I received all the messages i never got and then I put the sim card back into the Mi 9T and it seems normal again. Until randomly stopping again.
I like the phone and don't want to spend more money to replace a mint condition phone but this issue makes the phone a real pain to use, sometimes even unusable for messages and calls.
Has anyone encountered this issues and solved it?
I was considering if rooting and flashing a new OS from this forum will make the issue disappear.

I have those same issues honestly I've yet to find a fix. now that gpay has stopped working on miui 12 I'm gonna try rooting again and see if that fixes it

I fixed it by flashing Lineage OS, everything message and call related are working perfectly. With stock firmware notifications broke half the time, I missed a lot of professional calls with teams app, no notifications on screen for sms.... Despite all being set up

Flash rom with twrp then
FORMAT DATA with twrp
(Button at the bottom right of the Wipe pannel)
Then you will be able to boot ?

Cyanogenmod - cannot phone my phone, no SMS alerts...

Hi Everyone, I have searched for an answer to my problem but cannot find anything.
I have upgraded my G1 to Cyanogen, and everything works fine except I get no notifications to text messages, they just arrive, with nothing to tell me they have arrived.
Another problem is when I call my phone, it rings once and then gives an engaged tone. There is nothing coming up on the phone to say I have a call, however it does put the call in my missed call list...
I have checked GSM call settings but all forwarding is disabled.
I have just upgraded to the latest cyanogenmod with the updater software, however I still have the same problem.
Another thing that doesnt seem to work is the home button, and camera button, and the phone no longer locks.
I am at a loss for what to try, apart from trying to flash the phone back to its original state.
Any help would be greatly appreciated.
When you did the update did you wipe first? You can fix your problem, but you need to wipe your phone. So wipe, then reaaply the update. This does happen to people from time to time, and I've yet to see the direct cause or solution. A possibility is something in the dalvik-cache.

SMS issue with updated rom 1.66 WHY??

Hi,
I updated my ROM as soon as it came out in January.
I have been using my HTC HD2 on and off over the last two months due to its niggles but thought I would give the phone one more chance.
To my dismay again - I having issues with sending and incoming text messages.
For example
There was about a 3 hour window today where I suspect I was not receiving any text or sending any.
I noticed this because I phoned vodafone to give me an automated SMS message to tell me how many mins I got left. But after 2 attempts and left it for 90 mins, no messages came through.
I also sent out a couple of texts but noticed the delivery reports were shown as not delivered. These were two several different people.
So I thought this must be my phone then.
I switched off my phone and back on again, voila the messages I had sent were delivered 30 secs after my phone was switched back on.
I phoned up Vodafone again to get automated text message - viola the sms came within 5 seconds.
Question
What cause the cessation of incoming and outgoing messages in that 3 hour window? Could an app/update running in the background could have caused this?
Is this a common issue even with the latest official ROM update? Is there a fix?
Please help as this issue along with short battery life is making me thing whether to get rid of phone.
But I also love the other features of the phone - for that reason I want this fundamental feature of sending/receiving SMS message to be resolved.
Thanks -rant over
that sounds just like the original sms problem.
did you use backup software when you upgraded? with the wrong settings, when you restore it can cause problems by writing back some old system files.
could be as easy as a hard reset.
no I did not use any backup software. literally just installed the new ROM and then had to install all my programs manually in again. any ideas? it does seem like the old sms issue as the problem is much less frequent but annoying nonetheless lol.

Sorry to hear all your disappointing references your having with your HD2.
I not long after getting myne when had rom 1.48 and now 1.66 never have had any SMS problems(although a fix was installed by HTC straight away apon purchase)
I then installed a app to disable Sence Sms (sorry cant find where i got it from) being processed by Sence as it created a few limitations i liked in windows sms .
Any way by shifting the total responsibility back to Windows Sms functionality > i have never to today experienced a single problem with stuck sms.
I hope this helps.
but my problem is very intermittent. could a program running in the background cause this issue
I have an O2 HD2 which came with ROM V1.43 i had no issues with sms. I installed the V1.66 ROM...still no issues! It may be something to do with your network? might be worth trying a different networks sim card to prove???
I thought the same but i have no issue with my old phone. strange huH?

No calling, only SMS/data/wifi working on any ROM and/or stock

I've been using AICP for a while (Marshmallow), but haven't done an update in a while. By a while, I mean that I don't think I've flashed anything in weeks. Suddenly, I cannot make or receive calls today. Yesterday I made a number of calls just fine. I checked all the standard possible causes, dialer apps, default apps for phone, etc. After no success, I decided to flash back to stock.
Now I'm on stock 6.0. Same problem, cannot make calls. All I get is a screen which says "dialing" until it makes a tone sound and hangs up, never rings anyone. My phone never rings or responds when other people call. I do have full bars and service, and my APN is set up properly with AT&T in the USA. SMS and Data work fine, and so does WiFi. No other problems at all with the phone. I've had it for about a year and a half with no real hardware issues other than a loose charging port. No drops, no cracked screen or anything.
I'm wondering if anybody has a clue about what the problem with my phone is. I'm willing to generate and provide logs if there's a way to do that which could show the issue.
EDIT1: Derp, just tried the SIM in my girlfriend's phone. Seems to by my sim card. I'll go to AT&T tomorrow and report back here if the issue is fixed.

HELP. 6P not receiving texts/BLANK SMSC

To start, I'm on Android 7.0 using the September security patch and am rooted.
Never had an issue with this phone before. Ever since yesterday morning I have not been able to receive anyone's text messages. I'm not sure about MMS but I haven't gotten any of those either. The weird thing is that I can SEND texts just fine....and I can also send text messages to myself and they come through.
After digging and researching I accessed that hidden settings menu by typing *#*#4636#*#* into my dialer and looking at the SMSC number which should be for Tmobile, my provider, +12063130004. However, it's blank and I'm unable to change it. Hitting "update" gives me an "update error" in the field and if I hit refresh I get "+12063130004",145 with the quotes and the 145. If I hit update from there and reboot it's still blank. If I put in +12063130004 and reboot it's still blank.
I have data, I can make and receive calls and surf the web. So far I've tried switching sms apps to no avail. I'm currently using google messenger. I've tried removing the sim and placing it back in. I went in to TWRP wiped cache, dalvich cache and data and it did nothing. Finally I reverted to a nandroid I made about a month ago when sms was working fine and it's still not working.
I'm out of ideas fellas. At my wit's end here!
Oh, I should also let you know that I think this all started when my girlfriend sent me a text message that i received yesterday morning. It was the last text I was able to get......she's on a cruise so she sent it somewhere near mexico....I think it made my phone have a massive brain fart and I'm not sure how to fix this bug. Please help!!
No one? I've found nothing on the web..
This may sound obvious, but have you tried using a factory image to return to stock?
Sounds like you've done everything but that.
I suppose you could also try deleting your APN and manually entering a correct one for your carrier. That's helped me in the past on other devices when I've had weird data/service issues.
Funny you asked. I did a full wipe and returned to stock on the latest November build. Still a no go. People still get my texts and I can still use data/make and receive calls fine. I'll try the APN suggestion now.
As far as APN's go, I tried to reset them to default. I even tried deleting all of them except for the one I was using which in the past for other devices helped with certain issues. I then created a custom APN setting that I found on the 6p forum that helped other users with SMS/MMS issues....no help for me.
I can still send SMS,mms, make and receive phone calls. No idea what to do!!!
I have a similar but different issue. I can receive messages just fine. But sometimes when i send messages id say about 40% of the time my message gets stuck at the "sending" and it takes sometimes up to 10min for it to send. I can speed the process up if i go to the secret menu and toggle the radio off and on.
Im on ATT BTW. I thought it had something to do with ATT shutting down the 2G network and the phone getting confused as to which network to send messages on but im no expert its just a theroy.
PS. I had this problem pop out of nowhere. Had it start randomly on PN6 (last build) so i upgraded to PN7 same thing on 2 different versions of the ROM. And now im on SuperAx 7.1 and still have the issue.
Ive always had problems with Nexus's and messages. When i had the Nexus 5 i actually had to warranty it out because MMS all of a sudden would not work at all.
I received one text today from someone. That's it. Not getting all the missed sms messages and not getting any additional sms messages.

Cant send SMS... Sometimes?

I'm hoping somebody has experienced this before and found a fix and can help me out...
All day I've been struggling to send SMS messages... I'm on 11.0.1.1, magisk rooted, with RICE installed. Everything was working great but today when i woke up, i was unable to send SMS messages...
I'm receiving them, but sometimes they are delayed and i get a few at a time with nothing coming in again for a short time after that, but i've made no changes to my phone in the last 2 days. I've rebooted a few times between then and now (twice yesterday, just because), so i cant really understand why i would just randomly be unable to send text messages or why they are received in bursts like this?
I've gone in and reset my "Wi-Fi, Mobile & Bluetooth" settings from within the reset options, and this appears to fix the issue, but only for a minute or so and suddenly they stop sending again... I thought maybe its the tower, so i used my daughters phone to text my wife and that worked perfectly fine. Immediately before and after, mine wouldnt send.
Any ideas, links, or guidance that might help me figure this out?
Since there's been some updates and no responses to my thread, i wanted to revisit this and see if i'm still the only one on earth with this issue.
The issue seemed to have completely gone away on its own, no idea why or how... But a couple weeks ago i decided to install the update to 11.0.2.2 on my IN11AA. Ever since, my phone will randomly stop receiving SMS messages completely. I can still send, just cant receive. The only way to fix this is to reboot.
Anyone else with this issue? Anyone find a reason for this? A fix perhaps?

Seeming this issue doesn't seem to be widespread, could be a carrier side issue?
It's a shame we don't have dual boot capabilities because you could have switched to stock and checked.
Also try a secondary SIM from maybe someone in your household and send using that SIM and see what happens.
I know there are delays after rebooting, I do a lot of magisk module work and every reboot try sending notifications using SMS or some other methods and I get around 3 mins no send or receive but not at the length you do.

I just had the issue again yesterday. Wife and I started texting eachother at about 8am, except, i didnt receive any of her messages until 5:30pm when she got home and told me she had been texting me. I rebooted 3 times, which once usually resolves the issue but not this time. I had to go into the settings and reset my WiFi/Mobile/Bluetooth settings, then it worked immediately.
Because of the solutions, i wouldnt think its a sim issue, but im going to test it anyway. I've factory reset a few times in the past and i still get the issue. I've had the issue while rooted and not rooted. Four of us have phones, 3 are Samsung and then there's mine, and mine's the only one with the issue.

What SMS app are you using? I wonder if you have enabled RCS messaging the new Google style messaging? Because maybe it uses WiFi to download some of the SMS, and if your carrier doesn't support it maybe you only receive it when you are on WiFi.
Try on WiFi then try just on mobile data and see if you notice.
I attached a photo check the top setting. Google might be persisting your setting (if you are using Google messages)
Also why don't you and your wife try a simnswap next time you happen and you are both at home, if your wife doesn't receive it then it's sim/network related.

I'm using Google Messages, and yes i do have RCS enabled. I dont believe thats the case though because the messages that are blocked are sometimes just an "ok" message. I'm almost always on WiFi though too.
The primary issue with sim swapping with my wife is that we would need to swap sims for up to 2 weeks since sometimes I have no issues for 2 weeks, then i get the issue once or twice a day for three days. The worst part (for me anyway) is that her screen is SHATTERED on her phone (she's using a Note10+) and its hard to see anything, so i've been trying to get her to get a new phone. I think we might be FINALLY upgrading her (after 5 months) to an S21 Ultra, so maybe we'll give that a shot there.
I'm actually wondering if it has something to do with messages for web. I've noticed that the issue only really happens after using that, but.. It doesnt always happen after using messages for web, so it might just be a coincidence.
I'm pretty sure its not Google Messages, or RCS, and fairly certain its not messages for web, because i used to use Signal only, and i still had the issue a few times.

When you say "ok" are you just sending short messages or the suggested replies by Google?
I had problems with auto reply in notifications for a while.
Tbh I just use telegram or signal becuase they don't require being connected to the device directly when using the web/desktop versions.
Yeah swapping for 2 weeks isn't great!
Interesting you had this issue with signal too, sounds like Google cloud messaging (needed for any app push notifications and messaging) is in a standby mode.
You got naptime or servicely installed? Shame no one else is seeing this issue might be easier to diagnose
