Question Calling Some Numbers Results in Immediate "Call Ended" - Other Numbers Work Fine? - Xiaomi Poco F3 / Xiaomi Mi 11X / Redmi K40

Hi there
Wondering if someone could help me with this.
I recently purchased a Poco F3. Transferred all data from my Galaxy Note 9.
Everything has been going well other than this.
Certain contacts, when I call them result in an almost immediate "Call Ended" message (and that call ended tone sound).
It's as if the phone doesn't even initiate the call it happens so quick. The person I am calling doesn't get any call. No matter how many times I try calling the number, the same problem occurs. They can call me, I can never call them.
It's only happening with some numbers, others work fine?
I am unsure how to diagnose or fix this - I'm running MIUI Global 12.5.1 on SMARTY Network in the UK. I've naturally restarted the phone numerous times, tried airplane mode off and on, removed the SIM etc.

No incoming call notifications

My phone will switch itself off when in standby mode from time to time and it's a pain in the neck. I don't know if that's related to the main issue.
I can't receive incoming calls for periods of time, but I can still receive voicemail alerts. Yesterday, I was just picking up voicemail after voicemail. On top of this, intermittantly I won't get an incoming phone call notification, just the missed call icon afterwards.
I'm currently running Black 2.0 with Radio 1.38.00.10. Anyone got any ideas?
I suspect your phone is going into HSDPA mode and the network is not letting calls through during that time. I had the same problem on my non-operator bought phone with my provider 3-Sweden until I installed their extended ROM. If your operator hasn't offered a solution, you could try getting HTweakC and turning HSDPA off (this still allows regular 3G connections, which do allow incoming calls regardless).
I have a similar problem...
except mine has gone into this mode of operation permanently.
I'm running Black Satin & a radio ver 1.48 When I receive a call, the signal strength icon drops out & goes searching meanwhile the call is diverted to message box. My outgoing calls work fine as does both out & incoming SMS messages. I've tried changing swapping my sim card but it still does it with the different Sim. I've tried reflashing the roms & hard booting but the problem persists. I don't know whether this is a hardware issue or whether the firmware isn't working correctly with my operator vodafone NZ

[Q] Problems with Outgoing Calls

Hey everybody
So I've had my DHD on Vodafone since November. Since that time I've been having a recurring problem making out going calls as well as forwarding text messages and occasionally receiving calls.
Making Outgoing Calls: Whenever I try to make an outgoing call the phone will bleep and say 'Call ended'.. It does this alot at first it was across the board but tonight I seem to be able to call everyone apart from the person I actually need to call (typical).
Forwarding texts: I dont seem to be able to forward texts at all.. They get sent from my phone and it shows up as being sent but they are never received.
Receiving Calls: Less of a problem however every now and then people will try to call me and wont be able to get through.. Also sometimes the phone will cut out in the middle of calls.
Has anyone experienced problems like this before and if so what are the solutions??
I have tried switching the network settings and my wi fi is off and nothing has worked. I have also taken the phone apart and cleaned all of the contacts..
Phone already restored??
Sim Card tested in another phone, whether the card is OK??
Ask the provider to send you the right net configuration via sms??
only some ideas you can try....

Not Receiving all calls [i9250]

Hello All, I will start off by letting you know I am running AOKP M3 with the i9250UGKL1 (though this also happened before on the previous stock radio i was using), I am also on AT&T in northern new jersey. I work from my basement and service is pretty weak, 2 bars - 0 bars(though it still says I have service and I can make and receive calls). Before this phone I had a SGS2 I777 which never had a problem like this.
The problem is that sometimes when people call me my phone never rings, and on there end it continues to ring until given my voicemail, normally when I wouldnt have service or something it would go straight to voicemail, therefore the person would realize i was on the phone, or my phone was dead or something, but the problem is the phone rings on the other end yet I recieve no calls, I use google voice and have it set up that when I miss calls google voice sends me an email. So it is very weird, google voice recognizes that the call was missed and went through yet my phone never received the call or even acknowledges it ever happened. I can also call the person back from the same spot the phone has been sitting with no issue, so its not like i dont have service.. Since this is an international unlocked phone, I am assuming it would be pointless in calling at&t and seeing if they could do anything about it, So I am just wondering if anything else is experiencing anything like this or has a solution, its pretty irritating!

[Q] Number seems to be blacklisted, but not in call settings? CM7

I have a s5660, I installed CM7 on it and gave it to my boyfriend a while back, all was well.
But it seems MY mobile number has been blacklisted somehow within the last couple of days. When I call him from my phone it rings once then I hear a recorded announcement saying the person is unavailable. Then he gets an SMS from the carrier saying he has a missed call.
I can call all other numbers fine and he can receive calls from everyone else fine.
So I thought he blacklisted me, by accident (or intentionally who knows )
He swears he didn't, he's not too clued up with this stuff anyway so I don't think he has done it on purpose.
Anyway I checked the Settings>Call Settings>Blacklist, there are no numbers there.
My number still shows in his call log when I try to call him, as a 0.00 second call.
Swapped sims and it worked, so I guess it must be some setting on the phone somewhere, but IDK where, any ideas before I do a factory reset?

Random issues with outgoing and incoming calls.

Hello everyone,
I'm a new user of the G7 ThinQ, I live in France and have a fully unlimited plan with the operator "Free".
I bought a LG G7 ThinQ recently (model G710N) and it works good but I have an issue with calls.
Outgoing calls sometimes work fine, sometimes make me wait for around a minute then fail, and sometimes make me wait around a minute then work.
Incoming calls sometimes work fine, sometimes make the caller wait for around a minute, then get to my voicemail...
I searched the web about this issue and found an answer about disabling the Google app.
I disabled the Google app then made test calls (calling 2 contacts around 5 times each, then made them call me around 5 times each as well).
The test calls all worked fine, so I thought the issue was finally solved...
But then, back in real situation outgoing or incoming calls, the issue was back, while Google app is still disabled.
On a video, someone also disabled Chrome app, so, I did it too, but I don't know if it had any result yet.
Did anyone also have this issue ?
Any other trick to try ?
Thank you by advance.
Hello. If you have a ""refurbished"" phone bought from ebay/aliexpress, then you're not in luck. There's no problem with the google apps. The phone is mashed together with parts from different phones, different revisions, and those parts are not new. Especially the G710N, is very picky on carrier frequencies, and will randomly drop calls. You can try to flash an original rom, a korean one and see how it goes.
