Mobile Data turning off during standby automatically problem

I've been unable to get around this problem for the last few weeks now.
No matter what ROM my Milestone is on (It's the latest CM7 right now), it's been having problems keeping the mobile (2G/3G) data connection on, it seems lose connection every time the phone goes into standby.
At first I thought I was just losing connection to gtalk but I've caught the phone a few times coming out of standby with the data icon missing and then showing up a second later.
Other basic details;
I always flash the Singapore baseband from OR (which AFAIK is the same for Malaysia)
No battery saving apps
No Toggle2G use
WIFI has no data connectivity issues
I'm hoping someone can help me figure out this problem as it's a real killer to not get txts (gmail/whatsapp/etc), emails etc on-time

Going to try to leave wifi off for a day instead of a few hours for a better battery status screenshot but you can see what's happening in this one

In the period without wifi, and the period with actually, you can see I keep losing 3G/sync. This happens whether I'm moving or in the same location. Hell, it happens even at home.
Anyone think that flashing all the way back to stock froyo etc might help?
Are there any log files I should be looking at or posting for someone to help me with to figure out wtf?
I should also mention that this screenshot is from a FRESH flash of the latest CM7 from kabaldan, so I've ruled out (many many many times) that it's just a bad flash, or a bad rom (it does this on HO!NO!, FroyoMOD, milaq's cm6 and kabaldan's cm7 and probably others as well but those are the ones I've tried)
At this rate I'll get a new phone just for my sanity

I have the exact same problem with froyomod! help please!

update
I've flashed back to stock then to GOT 2.2.1 then to CM7 and it seems to have improved things by a lot on the first day. You can still see it happening however.

Looks like going to Stock -> GOT 2.2.1 -> CM7 has fixed my issue. More time needed but looks good already, I'm going to put down momentary loss of connection/3G as normal network issue rather than made by the phone now.
As you can tell, the last 2 screenshots have improved tremendously since re-flashing from stock
gosunta,
get on it, just follow the sticky'd posts.

I may have spoke too soon, it's still no good. New screenie in 6 or so hours to see if it continues.

Yep it's still doing it. It's worse when on the move and it obviously only notices its not connected/in-sync whenever I wake it up. I actually dropped the phone today and apart of me kinda hoped it would break so I could justify a new phone hahah .
Going to try going back a few versions of CM7 and see if that fixes it. Sick of this.

I had an idea a few hours ago of replacing the modded Talk (as included in Kabaldan's cm7 gapps or Ho!no! etc) for the stock one, so I went ahead and flashed gapps-gb-20110828-signed from the CM7 page.
Seems good so far over the last 2-3 hours, will report back in a day or two with screenshots. I hope this works. Also, if it does work I'm just going to go ahead and kill myself after all the flashing over and over of millions of roms (or so it feels hehehe)

There is no modding done to Google apps itself in the package I upload. Modding gapps is a bad idea, you would destroy the signatures by it, they need to match.
Only the updater script and app choice is modified.
Try to add this:
Code:
service dhcpcd_rmnet0 /system/bin/dhcpcd -ABKL
class post-zygote_services
disabled
oneshot
service iprenew_rmnet0 /system/bin/dhcpcd -n
class post-zygote_services
disabled
oneshot
to /system/etc/rootfs/init.mapphone_umts.rc like it can be seen here:
https://github.com/nadlabak/android...rebuilt/etc/rootfs/init.mapphone_umts.rc#L539
Let me know if it helped.
Btw., do you get connection to google servers at all when you switch to 2g only?

Hahah yeah I've just realised that your gapps isn't the issue, my bad kabs . It's still having the same problem now, lemme try your suggestion right now.
And yes, I do have connection to google servers while on 2g only.
edit in a few minutes.

Excuse the late reply as I've been busy but I figured it'd give me more screenshots of testing kabaldan's suggestion but...
Also note how the brown bars tend to correlate to when the phone is awake and even happening while the phone is awake.
It's still happening but I've noticed that the phone is at least capable of getting out of 2G and into 3G with some network activity which it has always done after sometime of use, get stuck in 2G and then I'd have to manually toggle it back despite WCDMA preference and no Toggle2G or Battery Saver usage.
I've noticed that I'm less likely to be disconnected from gtalk now though, it still happens obviously. My last chrome2phone sent link I waited 2 minutes with no response until I brought it out of standby and proceeded to use dropbox (thereby, I guess, it prompting to check connection to things...).
Kind of hankering to upgrade phones at this point but with the majority of phones being retail here and the fact that even a pre-order special of the Galaxy Nexus from my telco with a 24 month contract only results in saving less than 50EUR over retail, it would seem kind of stupid to get most phones still since everything is on the cusp of changing over the ICS :-/. Also STILL no droid3 here and I guess quite a few of us Milestone users love QWERTY like me

Same **** different day. Everyday. Going to now try updating to the newest CM7 and see if it still does it, been very busy (and disheartened by this issue as well) I only just noticed Kab's has 7.1.4 up.
I think I'm just going to start saving for a new phone

Have you tried using Toggle 2G/3G and setting 2G when screen is off? Yes, I know, it is not the solution, but, you would not gain anything using 3G with screen off and it would avoid this crazy 2G/3G/2G loop you get... I believe it is a decent work around.
By the way, in Brazil I got the same issue, only to realize that my phone carrier/operator is the one to blame, they have sold too much lines and their 3G connection is totally unrealiable due to that... When I saw that many of my friends were having the same issue with this carrier, then I've noticed that it was not the phone causing this issue... Perhaps somehow you are having the same issue, or, perhaps, someone build anything new between you and the tower causing this unrealiable connections (or perhaps you really have an issue). Are you sure you have flashed the proper baseband for your region? I believe CM7 comes with European Baseband (900/2100) which I believe is not the best for you....

The toggle2g suggestion might work, I'll look into it and see if it does it. However, I do think that I'm losing sync with g-chat even over 2G occasionally as well but I'll check anyway to be sure.
It seems to me that it specifically loses the data connection whenever the screen is off, as if its got a similar setting that it goes to sleep like "Wifi off when sleep". The actually annoying part is that when it does lose sync, it takes quite sometime before it gets it again (sometimes doesn't) or until I wake it. It looks like a loop but it clearly often matches against the Awake bars as well, ie the phone only noticing its not in sync (or 3g) when the phone is awaken.
Definitely don't have carrier problems, ruled that out as there's 3 others on same carrier at home without issue. Euro baseband seems to be the same thing but I always flash to Singapore anyway just to be sure.
I'll keep testing, I thought 7.1.4 CM7 update might fix this but it seems to be doing the same thing anyway . That reminds me that I need to try an older ROM and see if that helps.

kabaldan,
Any chance that if SU was denying radio permission that it would do this?
I've just noticed that in my SU logs radio keeps getting denied. In fact it has occurred to me that I haven't seen the Radio Allow/Deny SU screen every time I flash for some time now. I guess it gets stuck behind the setup-wizard screen and times out :-/
I'm reflashing to current CM7 right now and then if it happens again will Clear Data on SU and see if the radio permission screen comes up again and then check if its fixed my ****.

"Radio" asking for root permissions is Toggle2G.

Thanks for clearing that up for me kabaldan <3
I think I'm just going to assume my 3G radio is defective for now and put up with it.

Found this
http://code.google.com/p/market-enabler/issues/detail?id=116
Uninstalled it and reflashed.
Testing now. Looks good so far in battery stats.
EDIT:
Nope, not that either. OK I give up . It's definitely only doing it whenever it goes to Standby however. I've been running Sleep as Android lately to track my sleep cycles and it never loses sync when the screen is awake (the screen dims to minimum so that the app can track sleep, thus meaning the phone is always awake)

Any news on that issue? I'm having the same problem.

I'm having trouble with 3g and battery, my phone normally lasts for 16hs aprox with 6 hours of wifi and little / medium use, and I do not have a mobile data plan, so I never use it.
But, whenever I use 3g, my battery drops from 100% to 0% in less than 5 hours of almost "idle" and even with the screen off , it starts to heat like if I were playing Nova2 with a Walkie Talkie .
This is a battery problem or the mobile is not working properlly ?
Thanks

Bugs

Anyone notice any bugs so far with the one xl? If so, report them here. I'm getting some weird bugs.
Wifi issue 1: Sometimes when i leave a wifi zone the phone still shows its connected to wifi. Only way to get rid of it is to turn wifi off and then back on.
Wifi issue 2: It stays connected to wifi, however, i notice it jumps up and down quite often and doesnt remain consistent. Sometimes i loose connection at 0 bars and then it goes back to full.
Loading: Sometimes when i leave an application the screen needs to load and i get a "loading" notification in the middle of the screen.
SMS notifications sometimes don't notify me. I randomly have o check myself.
Facebook private messages don't notify me as well. I have to manuallty check. Even though its set to sync.
Sometimes my sim needs to re-register.
This is my second HTC one XL unit. Also, rogers cannot get lte to work on my device. Yes, i have an lte sim and my account has an lte plan. I just came from a sgs 2 lte.
Let me know if anyone else is experience any bugs?

Those are some serious bugs that would be a deal breaker for me. Hopefully it's just a defective unit and you could get it replaced?

Like i mentioned in my previous post this is my second unit!

I can safely say I have not encountered any of those issues yet.
LTE is working great (on Telus). No issues with WiFi. All SMS notifications are working. Haven't received any Facebook PMs yet, so not sure about that.
One issue I have noticed, though I'm not sure if it's with the device or with specific apps, is that some apps that have a dedicated menu key will still show the soft menu key at the bottom of the screen.
e.g...
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Note the app has it's own menu key, yet the soft menu key is still visible.

I previously stated my wifi was fine, but I am starting to notice some issues with it lately. It seems to drop connection from time to time. Sometimes my SMS also will not notify me, or if they do, I won't have a flashing green notification led.
I was having a problem earlier saying something like 'Network access changed. Calling is restricted' and forced me to have no signal. Switching airplane mode on/off fixed this problem, and playing around with the network mode (gsm/hspda/lte) seems to have fixed this problem for now.

I get the same issue with the calling is restricted issue. Then it registers the sim again. Seems like we have some of the same issues. These issues were both persistent on both of the HTC one xl phones i had.

I wasn't sure if it was from a screw up of mine or not, but I've noticed Wifi drops as well. I think I've had some network drops too but never any dropped calls and it's difficult to diagnose as a certainty.
The wifi definitely drops though. Hope a custom kernel with better wifi drivers comes out.

Haven't seen those on AT&T's version.

I've been using my One X nonstop since I got it yesterday, I haven't noticed my WiFi drop even once. Though I'm connected to a 5Ghz network; I've switched to my 2.4Ghz network now and I'll report back with my results later.

Does the AT&T version have a different radio baseband or anything? Otherwise, the AT&T and Rogers are the same model (X325e).

i believe our model is PJ83100... i could be wrong on that though.

I have noticed the wifi issue. It's fine when I'm near the hotspot (say, in my living room), but if I go out onto my deck, a place that other phones have no issue with, it goes completely squirrelly.
Rogers LTE is definitely weaker on this phone than on the Samsungs. At work, I get one bar with this phone (sometimes two) when I'm on LTE. With my Note, I got 3 or 4. It doesn't seem to affect the speed at all though.

Bars mean nothing... check the signal strength in dB to do a fair comparison...

LTE has been fine on mine but again I am in Calgary and the Rogers coverage here isn't the best for LTE, so I don't get in the coverage area often but even without LTE coverage my device is pulling 12-13/Mbs which I am more than content with.
I have experienced some minor signal issues with Wifi but nothing worse than what I have experienced in the past with my Galaxy SII (I9100M). The only real bug I have experienced is in the official twitter app.
Each time I go to compose a tweet the screen sometimes glitches out for a second before the popup to compose the tweet appears. That is all I have found so far.

I don't think that's the correct number.
I've been looking into this over the last few days. After all the videos I watched and reviews I read, etc. I can only find two models of the One X. The HSPA/WCDMA "International" variant, the S720e; and the HSPA/WCDMA/LTE variant, the X325a.
Everyone in this forum should have the X325a.

The pj83100 is the number listed on the pre order
HTC
America
Inc.
PJ83100
WHT
PHONE
Maybe just the number used for pre order or something
Sent from wherever I am!

Ah, I just got the "no SMS notification" bug.
It happens when you leave the SMS app open when the screen is shut off. Even off, it assumes you're in the app and doesn't generate a notification.

That is how ICS (Android 4.0x) displays the menu button on legacy apps that have not been upgraded to the new ICS standards yet when being displayed on a phone with hard buttons like the One X. When a phone has the on screen buttons native in ICS (like on the Galaxy Nexus or some tablets) those dots show up as a fourth button on the bottom menu bar. Over time, as developers come into compliance with the new guidelines, I am sure the dots will go away or move to the top where they are supposed to be. I see that that app has a menu button up top but I would try something like Google Voice that is done "the right way" to see if you get the same result. For now though it is a monster waste of space.

I get the sms notification bug as well. And I think it happens not only when you have the app open and the screen off, but also sometimes when you're using the phone (and maybe the app is running in the background).
Also experiencing the black screen and re-loading when app switching.
One that hasn't been mentioned, is while typing, I sometimes get a "strobe" like flash of the screen. It flashes really brightly for a mili-second, and then back to normal. I don't think this should be confused with the "flickering" that so many people who have the international version are talking about. I'm using swiftkey, so I suppose it could be related to that, but I don't think so.
Hopefully all of these bugs are software related and will be taken care of with an update.

They seem all software related. Im of course experiencing similar issues! the phone still rocks! just some bugs need to be resolved. But nothing to hinder your daily use.

My WiFi/SMS notifs are fine, however as for Facebook, I've never had a single device that properly notified me when receiving a message, and therefore deem that a Facebook issue, not a One X issue. I've not had any problems with mine whatsoever.

Phone modem/radio dead?

Not sure if the phone radio is completely dead or not but I've lost all signals completely today. Nothing I do works.
If I go into Mobile Networks and choose Network Operators, the phone is able to scan for the networks and showed my correct carrier in the list. However I choose to register on it, it doesn't work. It just keeps scanning and doesn't register.
Tried flashing new ROM from scratch with new radios from CM and Oxygen (230 and 241) and neither works. Tried flashing via recovery and fastboot. Tried restoring from a working TWRP backup, still the same issue.
I took my SIM card out and tried on an older phone, works fine. Used another working SIM card on my OPO, still doesn't work. At this point, I think it could be a hardware issue with the phone. Only thing I'm confused about is why it's able to list the carriers in Network Operators and this was never an issue in the past. Also, it doesn't show a question mark in the signal bar so that would lead me to think it's detecting the network but not fully working or registered on it for whatever reason.
All I see is completely no bars in my signal bar. I can't dial or receive calls, I can't use emergency calls, but it does pickup my network as Vodafone NZ. Any ideas?
Update:
Switching to 2G, 3G and LTE doesn't do anything, still no signals. Also, looks like the Network Operators function is irrelevant to your SIM card. Unplugged my SIM and it was still able to scan for it.

I suggest you to try kitkat modem on lollipop os. I know someone has the same problem with you .I dont know why but some OPOs does not work with lollipop modems.

Do you get to see your IMEI No.?

Yes, I do see my IMEI. Have tried all the solutions there are.......flashed oxygenOS, colorOS and imei is still there. I can see there's signal under About -> Status, but no network (unknown). My wifi works fine, just no phone signal.
My sim card is fine, tried on other phones and it works. Tried several sim cards in my OnePlus and they all fail. Wasn't like this last week, dunno what happened.
I think maybe my IMEI is blocked? I called my carrier and they said it's not. Will i need to contact OnePlus (my phone is the chinese version) to get this resolved?

Same problem. No reason. Just started happening last week...
I tried another network and it worked though.

Exactly the same problem here. It first happened when I traveled to Japan and inserted a Japanese SIM card, nothing worked, so I thought it's because of the strict radio regulations in Japan....now I'm in Ireland, popped a 3 Mobile sim card in, still not working.....God I would never buy a OnePlus product again....first the touch screen failed, now the modem......biggest mistake taking it travelling with me....

@chaoscreater @dahole @victorinoxs I have your same problem
IMEI, Baseband and WiFi are OK but no signal and status network unknown

Solutions people ! I am reading post forums , nobody haves a solution for this, is my phone Garbish?

I've got same problem after i forgot to connect antenna cable near the battery that comes from bottom board to main board. I've seen networks, but i were unable to use my phone inside any building

I am having the very same problem and, once I opened the One up I found the connector was disconnected.
But ... how to connect it back? It looks like it's a very difficult task to be accomplished!!!
SOLVED!
You can gently pull the pig tail cabletowards the center of the battery compartment, you connect it then push the cable back in.
The small narrow cable compartment that's on the side has a "soft curtain to keep the cablew in place. Be careful to put everything back in place properly.

Antenna goes to bottom board near battery under rubber cover that you can unstick, connect and stick back. Just disconnect battery and pull antenna to the side of power button until you will be able to connect

Yup! I "discovered" it shortly before you answered. And it worked indeed!!!

Same network issues !!
Hello everyone !!!
I'm new here and so dont know much how stuff works here. Hope to learn pretty soon
The thing is, I'm having similar problem with my OPO. I get only 4G network, no other network (2g/3g) gets connected. When on 4G, network randomly drops and connects, and when connected I can use internet, but just cannot make/recieve any calls. I have flashed many custom ROM's but to no avail. Finally after getting nowhere near solution, I stopped trying and currently I'm using Lineage OS (ver 14.1.20171001-NIGHTLY-bacon).
Drmuruga posted a link with CM13 modem zips, will flashing the CM 13 modem file work in my case ? If yes, there are two files on the link you provided, which one should I use ?

Firmware can be a game player for sure.You can use modem from cm13(any of them,the first one is from snapshot builds).Infact, have a look at: https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214
Which carrier are you on?

I am on Airtel (only 4g). I've tried using docomo as it is my secondary sim, but it never connects since it works on 3g network.
I've tried a couple of those from the list, but failed. Anyway, I'm gonna try the rest.
Does TWRP version matters ? I'm using 3.1.1-0.

It just needs to be latest.Try dialing *#*#4636#*#* in phone's dailer.Then,head over to Phone Information and you'll see preferred network modes.See attached screenshot.

Yeah I tried through that long before, but as soon as I set it on wcdma (only/preferred), there isn't any network (emergency mode only).
I've tried almost all firmwares from the link you provided using TWRP, but no luck. Maybe my card slot must have some hardware problem. Just to give it one last try, can you tell how I can Install those firmwares via ADB fastboot ?

Doesn't matter.Twrp flashes the firmware just fine.
Ps- It could be network antenna.Any recent activity that could damage the phone's hardware? Jio 4G,Bsnl 3G and Airtel 3G works fine here.I'm gonna get my Airtel 4G sim tomorrow,and I'll keep you posted if it works too.

Access Point Name settings are not available for this user - Poco X3 NFC

Hi everyone,
My Dad is having a problem with a Poco X3 NFC that I hope someone will be able to help us with.
I bought the phone for him as a Christmas present last year from Amazon Germany, as his previous phone was quite old and had been having occasional issues, and poor battery life. We put his SIM from that phone into the new Poco X3 NFC and initially it seemed to be working fine, and he was very happy with it. However, after a while it started having issues where calls would occasionally drop, or he'd be unable to make a call. I took at look at it on one of these occasions, and noticed that the network reception icon at the top was greyed out, and had an x through it:

Each time, a reboot fixed the issue, but it was annoying, and occasionally people couldn't reach him when they phoned him, presumably due to this same issue. At first we suspected the SIM, so we ordered a replacement from the network. Unfortunately the same issue occurred with it installed in the Poco X3 NFC. Then, to test this new SIM, we tried putting it into his old phone, which he then used for about two weeks. The issue did not occur on this phone during this time, but it occurred once again a few days after putting it back into the Poco X3 NFC.
So, we then thought that the problem was with the Poco phone itself. We contacted the retailer and they sent us a replacement (same model), and we set it up again. Unfortunately, after a few days it also exhibited the same problem. While the replacement phone was having one of these occurrences, I looked into it a bit more, and found something unusual in the APN settings. Here is how that screen looks when there is no problem - you can see the entry for our phone network:
However, when the problem occurs, I've discovered that the APN entry on this screen is missing, and instead the text 'Access Point Name settings are not available for this user' is present:
I believe the disappearance of the APN settings is causing the phone to lose its connection to the network, but I don't know why this is happening.
I did some Google searches for the above text, but a lot of what I found seems to be related to this being a permanent issue, not an intermittent one like we have. I also spoke to Xiaomi on a live chat on their website about this problem, but I wasn't confident in what they suggested. They first of all suggested that poor network coverage could be causing the issue, until I pointed out that this should not cause the APN settings to disappear.
They then advised trying a factory reset, and said if that didn't work that it could be sent away for repair. I don't think this is a hardware issue, and given that it's intermittent and we don't know how to recreate the problem, and that two models of this phone have both had this problem, I don't think sending it for repair will work. I'm also not keen on trying a factory reset since I'll have to back everything up and reinstall everything afterwards, and again, since both models of the phone had the issue, I'm not confident this will work either.
The representative on the chat also suggested that one of the applications installed by us could be causing the issue, but I'd have thought this to be pretty unlikely. I thought settings like this would be protected from other applications, and Dad only has a handful of applications on the phone, all of which are well known with thousands of users. All of these applications were also installed on his old phone and caused no problems there.
In case they are useful for anyone trying to assist us, below are the software versions on the phone. We've installed all prompted updates, and the problem still occurs with all of these installed.
Sorry this post got a bit long, but I wanted to include everything we experienced and tried so far. If anyone can help us out with this or suggest anything we can try, we'd be very grateful. Dad is very happy with the phone otherwise, but unfortunately it's not usable to him if its network connection isn't reliable.
Thanks in advance.

Please replace your SIM card.
I had this issue before too and it drove me nuts. I did all the steps you too undertook including getting a replacement phone. The solutions eventually was to get a new SIM (Of the same number.)
Even if your current SIM works fine in other phones, there is this weird pairing issue that occurs with Poco X3. There is already another user on the forum threads with this same issue who got it fixed by getting a new SIM by my suggestion.

Hi Alrich,
Thanks for your response. The thing is, with the first Poco X3 NFC we had, we tried a replacement SIM in it already, and we still got network disconnects and the X in the Network Reception icon. Admittedly, back then I wasn't checking whether the APN settings were going missing, but I suspect that would have been the case if I'd checked. Also, the replacement SIM that's having this problem in the current Poco X3 NFC works fine in Dad's old phone.
Is it likely that the SIM would work fine in a different phone, but still have problems in the Poco X3 NFC? I thought a faulty SIM would cause problems with any phone it was put in.

Though I don't have x3 NFC but the x3 pro, there's still some way to try.
You see the "Add APN" on your first screen shot?
Did you try manually adding the APN settings on your own?
Note down the APN setting from your dad's phone and manually type in your X3 NFC.
If you don't know the APN settings for your telecom service, you can ask your number carrier.
I guess you're in Ireland, so you can try this APN setting
Tesco Mobile Ireland APN Settings for iPhone 2023 - 4G 5G APN Settings
Tesco Mobile Ireland 4G LTE 3G APN Settings for iPhone Tesco Mobile APN Settings for iPhone In your Apple iPhone go to Settings -> Cellular -> Cellular Data Network -> APN and enter the following details Cellular Data: APN: tescomobile.liffeytelecom.com Username: blank Password: blank LTE...
www.apnsettings.org
Also remember some telecom service uses specific 4G bands that some phones don't support. So in this case, your phone can't find any signal, and it has to broadcast and try other bands to check if it works.

Try using 2g only or 3g only instead of lte/4g..... I am also having this kind of problem if set to 4g as preferred network.... There is problem with this phone 4g reception as I've used different phone at same location and the coverage is good.. Only with this poco x3 the 4g was unstable.

Question Signal problem only resolving after a restart

im facing a problem, i use 2 sim cards so whenever im in an area of bad coverage i completely lose the signal, the problem is when i went to a good coverage area, the signal is staying dead till i restart my phone. Airplane mode does nothing only restarting or if im just using one sim card (which is not an option unfortunately)

did you try to check the " Automatically select network " under mobile networks in the settings app ?
try to turn it on , or try to select your network manually

did you check if the problems happens when only ONE sim is installed?
are BOTH simcards of new generation? (I don't mean to support 5G but to be manufactured the same period).
It's useless to use simcard that is more than 5 years old. They cannot communicate with all new signal standards.

it works fine if i just have one sim card
yes they are ( one is like 2 years old and the other is ~3 years )

Does it make a difference if you use Sim card A or B when using only one sim card or do both of them run like a charm in single mode? Did you try to combinate sim a or b with a totally different simcard (from a fiend for example, or change the ports for A/B) ... did it ever function in the now used/wanted combination? Sorry for my bad english...

What is your OS system? MIUI or custom ROMs?
Does the signal comes back if you change "Preferred network type" ? Like switching to 2G only, wait for 30 seconds, then prefer 3G, wait for 30 seconds, then prefer LTE/4G ?

If you are in MIUI, you can also try forcing 2G only, 3G only LTE only as in following Xiaomi forum
https://c.mi.com/thread-2683781-1-0.html
This does not solve the problem, only some workaround to try to make your signal back without rebooting.
To solve the problem, report to Xiaomi or Poco. Or ask in the custom ROM thread if you are using custom ROMs.

try to check your network maybe they having their maintenance or you can use another sim if you have to check if it's still the same.
