Duel sim not functioning properly - Samsung Galaxy S9+ Questions & Answers

I have the duel sim model on T-Mobile. One line for work, the other personal.
I previously had a OnePlus3T, and the S9+ doesnt seem to operate at all the same.
My OnePlus3T didnt forward or deactivate a line when I was on a call on the other line. They both worked all the time, as wanted and expected.
I am constantly missing calls and there are times I dont get texts till hours after they were sent. There are no notifications that I have missed calls either in the status bar or in the call log.
I cant afford another phone and I'm not going back to carrying 2 phones. Is there some solution?
Further, when "dual sim mode always on" is active, it does NOT always forward the calls to the line in use. It is very frustrating.
And I'm curious, if calls are being forwarded to the other sim, what number is being displayed on the the callers phone?

I don't receive incoming calls!

So, with the stock root rom, with a few different roms, and even with different kernels and radios, I don't ever receive incoming calls (though if I make an outgoing phone call, it works just fine).
Anyone know if this is something I can fix? Or is it an issue on Verizon's side? They had to go through three 4G SIM cards before finding one that my phone could actually activate with, so I'm wondering if that's the problem.
Did you set up call forwarding? Try calling *73 as this disables all calls to be forwarded, and try again.
You know what? I think you might be right... before I got my Thunderbolt, I had an OG Droid set to forward calls to a different temporary number...
My phone is going through a restore right now, so the INSTANT it boots up, I'll be dialing *73.
EDIT
VICTORY! It must have kept the call forwarding on the line. Thank you SO MUCH.
you're welcome.

Why does it always say "Conditional call forwarding active" when I make any call?

Why does it always say "Conditional call forwarding active" when I make any call?
Hi there, basically I bought a new and sealed T-Mobile branded Samsung Galaxy SII phone from eBay and am using my 3 mobile sim in it.... I assume it wasn't originally locked when I bought it, as I went through the root and unlock method (ChainFire app), and the code was 00000000, and never at any point asked me to enter that code into the system, so hey, my 3 sim seems to work in it.... apart from the fact that for every call I make the message "Conditional call forwarding active" always crops up with a beep to go with it, then after a couple of seconds the call is made. It isn't a major problem as such I don't think, but hell it definitely isn't normal and is quite annoying after spending £400 on this otherwise amazing phone.
I have tried to fiddle with the settings but for some reason I cannot disable any of the call forwarding settings, some sort of error message crops up. I have phoned up the 3 network who I am with three times today and they asked me to enter a few # codes to sort the problem out, but I had no luck, and then they had me factory reset the phone using the option in the settings. I did that, and I still have this problem. I also get the message "Connection problem or invalid MMI" when entering most # codes, this seems to have happened after rooting, though I am not 100% sure if that is the case.
My phone is the Samsung Galaxy S II I900, just to confirm that.
I look forward to hearing from you guys
I am on Three and I get the same message although my S2 was purchased from O2 then rooted. I have not seen any other reports about this but the message has not bothered me.
I have the same message. Ave tried several hings without success, however since it really does nothing, I am starting to get use to it. But if someone knows how to solve it please let us know
voice mail
Hi guys i have this to but it only started when i activated my voicemail so i think its down to the voicemail
e.g if your on the phone and someone else calls they are placed forward to your voice mail ???
hope this helps
Hey there guys, thanks for the replies so far, glad to hear others are experiencing this annoying problem. I seem to have had this since rooting it, originally T-Mobile though I am 99% it was never "locked" to the network for some reason as I mentioned as I have never had to enter the 00000000 code, which the free ChainFire sim app gave me (seems like it means it is unlocked already???). The guys on the 3 helpline were giving me loads of codes which weren't of any help, and telling me about what options I could fiddle around with, but I had tried all of these to no avail.
Are people also getting the MMI message I mentioned in my original post, whenever they enter # codes in the dialer? It seems to me that both of these problems started at the same time (this error message and the forwarding issue - I am sure they are linked). It means, for example, I probably won't be able to set up a speed dial because of it, nor will I be able to use the "secret codes" as mentioned in the dedicated thread of the same name on this site.
Why is it a problem for some and not for the majority of people, we must have something in common which we have done with our phones which has caused this?
I really hope someone can sort this annoying problem out.
It's normal. "Call Forwarding Active" is displayed when all calls are forwarded. "Conditional Call Forwarding Active" shows when forward when busy, forward when unanswered, or forward when unreachable is selected. To make the message go away you'd have to disable the three forwarding options in their settings. The pre-populated number is always your carrier voicemail (read from the SIM) or Google Voice.

Cheers for the reply Barry, yeah I expect it is normal but the thing is I cannot change these settings, my phone won't let me as an error comes up. I know it's not a major problem, just a bit annoying I can't get it to go away. I can't disable those three things, I tried a few times already.
Plus, I constantly get the MMI error message, which I mentioned before, seems a bit of a coincidence how these problems started the same time. I can't enter the majority of "#" codes into the dialer, it always says "USSD Running" or something along those lines and then produces the message like 2 seconds later.
Any ideas? Thanks so far for the advice
I have this problem but unlike all others I cannot make any calls on account of it. When I try to disable call forwarding I get an error msg saying it's not supported by the operator.
There HAS to be a way to fix this. I cannot make any calls or use 3G.
Try this
menu-call-additional setting-select network default...
It work with my sgs2.
On the Galaxy S2 if you go to: settings-call-call settings-call forwarding-voice call forwarding -- You will most likely see that for unanswered or unreachable calls it's not disabled because it forwards it to your voicemail, that's why it says conditional call forwarding is active. If you disable all options you won't get the message but then unanswered calls won't go to voicemail.Hope that helps.

you realise thats almost a year old? Check the dates on threads before you post
ADMIN EDIT: True, but it is a current issue for some people so it's still valid to answer the question.
Doesn't work
My phone drops every call, even with SIM cards from different countries and in all conditions. Thinking this call forwarding might have something to do with it, I tried to deactivate it, first through the settings -- no luck -- than by reformatting the phone. Nothing, cannot get rid of it because it says it is set by the 2 different phone companies I use.
I don't mind the message but when I call someone, I can hear that the call is being sent somewhere, there is a 1st ring, then it rings the other phone. Does this have to do with call forwarding? Can it be interrupting the phone signal and causing the call to drop ?
I have also removed both the Turkcell and Telefonica SIM cards, put them into another unlocked phone and tried to cancel but as soon as I put them back, the message returns and my calls drop.
Im also getting this error when I updated to 4.1.2 and used galaxy s2 sim unlock
Has nothing to do with call forwarding !!!
The Message worked on all AT&T cell phones, since i can remember,. i been using go phones since 06..... and they all had this message when right after the number was just dialed, right after pushing the green phone icon button to dial it , right after entering the number to be dialed on the keypad.
I have found this message on LG Cell Phone 500 CU series... and all my other phones as well...
IT is NOT a CALL FORWARDING ISSUE>.. because i had worked on that for awhile myself...
IT is a Carrier Issue I believe.
and it doesnt happen ever single time , just on certain days . not sure, why... but perhaps, call your carrier and ask them what type of phone they have your phone listed as.
Then tell them the model and make u have. that might change things... Cell phone carriers know how to mess with your phone and break it too...
so if ur having issues with messaging, call forwarding, it just may be the settings the carrier has you listed or down for.
blah.
anyways. yes it is annoying, i just got a new phone, samsung galaxy express. it is starting to happen too on this one. but had it for a few days and it never showed up till about 2 days later.
I thing it is perfectly normal for your device to display this message, I'm central america and mine also says the same thing anytime i make a call "Conditional Call Forwarding Active. However since I have a prepaid or pay as you go plan with my carrier and whenever I have no more credits to make calls i get the message "Calling Barring Enabled". I guess it has something to do with your carriers settings, it doesn't bother me at all though since I'm already used to it so hope that helps.
Enabling call forwarding for real and then disabling it seems to work
I got the same error also on every version of the stock rom (it used to appear occasionally, though) on my Samsung Galaxy S2 (i9100, without g), in that case going into forwarding settings was enough, because the mobile used to read the current configuration from the network and recognized that there was no forwarding active!
I moved to Cyanogen Mod 10.1.3 / Stable and going into forwarding settings was useless... He was updating with the data from the newtwork, all the forwarding options were disabled but the notification message was still there...
I decided to enable it for real by putting a friend number from the same carrier and then disabling it immediately after, and it solved my problem! Hope it helps!
PS: I'm not sure that enabling the call forwarding is free of charge, just double check with your carrier first!

I had the problem. Just solved it. select any one sim. Select settings-call settings-call forwarding-make sure all the options listed therein are disabled. Do this selecting all your sims one by one. The problem will have solved.

[Q] No incoming calls

I've had the Galaxy S2 for about 2 months now without any problems.
As of last Friday, I can't receive incoming calls. People who try to call me hear one beep and then they get my voicemail.
Outgoing calls work just fine, as does SMS (incoming and outgoing).
I've put my T-Mobile SIM in another phone and then it is able to receive a call. Another SIM in my phone -> same problem: no incoming calls.
So I figured it must be the phone.
Customer support has started an investigation but that can take up to 1 week, so I thought let's ask XDA.
Can it be a simple setting that I've accidentally changed? Pretty often when I take my phone from my pocket, the screen is unlocked so that could be a cause.
If anyone has a clue or an identical situation, please let me know.

Does your phone ring when a call comes in and also does it go straight through to your voicemail?

Straight to voicemail. But I've figured it out after 3 days
There's an option to automatically block all incoming calls in the settings. Must have accidentally been activated when the phone was in my pocket.

In my case, the phone does not ring when I get a call at all. I have searched hi and low and I cant find a solution. I have rebooted, i have reflashed, I have changed my ringtone and nothing seems to work, please help!!
Hello my girlfriends SGS 2 has almost the same problem it cannot receive calls sometimes even though she can call everyone. The problem seems to fix by itself sometimes and it appears random.
I read that there was a problem with the samsung galaxy s when using 2G/EDGE connection with data activated and the problem was that the user could not receive calls randomly.
Can you confirm that you are using 2G/EDGE connection and Data activated? I am also trying to find the cause of this problem...
Hope my research helps good luck and waiting for your reply. (http://www.samsunggalaxysforum.com/...eive-incoming-calls-and-sms-while-using-edge/)
Later EDIT ---
She also has a vodafone provider but i have the same provider and never had this issue. Also no call filtering is done.
Make sure Call Forwarding is Disabled under Settings- Call- Call forwarding. And also try to delete the Voicemail number if you had set any.
Regards.
it's nothing Call Forwarding is Disabled related it is because of EDGE connection you can't have a sync or internet connection and while "dialing" data receive calls if you want to call anyone the network prioritizes and let's you dial whoever you want but it is not the same thing for incoming calls
^ Went over my head !
had the same problem in a bad 3g/data coverage area. solution was simply to turn data off and the calls started to come through.
turned data back on and now working ok.

Help, Sending Callers Directly to Voicemail

I received a replacement Atrix today and for some reason, it is sending callers directly to voicemail. I only know that they called if they leave a voicemail. I can't seem to figure out how to change it.

You need to go back to your service provider and have them check your phone and SIM card. This usually happens when the system cannot "find" your device on the network meaning something isn't connecting correctly. It's the same thing that happens if your phone is turned off. Network sends out a signal to see if your phone is there, gets no response, sends straight to VM.
Alright, thanks. The weird thing is the phone works fine when I call out. Only problem is when people call me. They sent me the phone with a new SIM, but it didn't work so I put my old SIM in which I'm thinking might be the problem. I'll run up there tomorrow and bring both SIMs to be sure.
settings - call settings - Call forwarding. Make sure Always Forward is disabled.

I cannot see from the screen which SIM the incoming call is on.

Hi I apologise in advance if I am posting in the wrong place or I'm just being a numpty.
I suspect it's me being dumb that's the problem but when someone rings one of my 2 SIMs in my Xiaomi Note5Plus with Global ROM from Xiaomi not flashed, I cannot see from the screen which SIM the incoming call is on. OK, I have 2 different ring tones set-up and that is fine but on silent/no vibration or if I miss the call, it's a real nuisance not knowing which SIM received the call. As an example, if I make a call to each of the SIMs from another mobile, then my phone just shows that I have had 2 calls from that mobile, rather than one call on each SIM from that mobile.
My old THL2015 did this automatically and so I could always tell what was going on.
The reason that this is particularly important for me is that SIM1 is for use by everyone who calls me and SIM2 is my back up line. If someone calls me, I need to know (if they are not in my contact list) whether this is a "real" call or a junk call on SIM2.
Hope all that makes sense and one of you kind people can suggest a Settings solution or an app please.
My thanks for any help offered.
