Save preferred SIM card per contact (dual sim operation)

andrej567

Is it possible to save per contact which SIM should be used for calling? Maybe it is well hidden - did not find it.
Also, when I click on a missed call, to call that person, it uses the default sim, not the sim which received the call.

Have latest stable on pixel 7a. thanks!

Bringing up old conversation, I know, however the title of this subject is perfect for my question and yet I do not see a solution. As the original post mentioned, "Maybe it is well hidden - did not find it."

Here is my scenario and I also can not find a solution:
I have a hard sim card (my main phone number I use 95% of the time)
I have an esim I use for the other 5%

I see not way to dial out based on the number you want to use. I am finding that I must first dial out on my default preference, then (as quick as humanly possibly) click "change sim".

GOD this sucks!.
1) I am hoping I click the button quick enough that my main number is not leaked
2) I am hoping I REMEMBER to do this in the first place.

Was hoping to find the ability where I can choose a contact, then somewhere inside the contact choose a "default sim to call out on" feature? Did I miss this? Was it already implemented because I cant find it.

I have looked for this feature as well but there seems to be none. Best compromise was to set the SIMs to "always ask" since I already leaked my private number once to a Business Customer...

N1b this solution doesn't work if you use a BT device (car BT by example) to initiate a call, due the phone opens the select sim dialog in the phone device even when the call is initiated by the BT device and you can't use the phone while driving

The workaround mentioned by N1b doesn't work for you?

If you select Settings> Network & Internet> Calls &SMS> Calls> ask every time, you will be asked which SIM you want to use each time before the call is established. The call is only established after you have made your selection.

An additional protection against leaking your phone number: For contacts who should not see your number under any circumstances, you could add the corresponding GSM code to their numbers in your phone book (depends on your home country, e.g. #31# or *67 - it is best to test it beforehand).

N1b: thanks!
80% time I use sim1. Not leaking the other sim accidentally would be really good.

does anybody have experience with some phone/contacts app having such feature?

i'll look up something myself, of course. i am trying to avoid adding some bloatware. paid apps are acceptable imho.

A potential solution would be to use two different dialer apps and limit access to each respective group via contact scopes.

[deleted]

[deleted] that doesn't tell each dialer which sim it should use, does it?

[deleted]

[deleted] I no longer have a dual sim setup so I can't verify, but the default AOSP dialer app has an option under settings for calling accounts. I recall you can set the default there, but it'd be worth testing.

I tried phone app from work profile (using island). First it seemed both phone apps modify the same setting but now it somehow seems to be stabilized and the work profile phone app uses second sim to call! i tried to restart and the setting stayed as I wanted.
Thanks, it is a better solution to install something additional. Not exactly intuitive but usable for graphene fans.

I just moved my second phone line (personal, I have been using esim for my professional line) with a physical SIM. This does NOT WORK WELL! I have texts that may need to go one way or the other, and even checking 'ask every time" does not work - it says "no preferred sim selected for sending SMS messages'. I have to go to settings and make one line THE sms number, then it will send. It doesn't seem to follow the previous number (ie a text TO one number seems that it should automatically go out using the same one). This does not seem very workable for me.

It also would be helpful to be able to rename the line to 'personal' & 'work' instead of BOTH simply saying 'Verizon'. One is in BLUE, one in GREEN, but that is not a good way to do it.

EDIT TO ADD: a LONG press on the 'send' button does bring up both numbers, but then pressing one of them simply yields the same message. This appears to be a bug in the messaging app. Is this thing really NOT ready for dual sim? I'm on a P-7 and if it doesn't work any better than this, I may end up picking up a cheap trash phone & give up on security for one line. It simply isn't usable as a dual sim if this is as good as it gets.

This is my first disappointment with the phone/OS. Is the implementation on stock android this bad? I cannot see anybody actually using a dual-SIM setup if they actually want to be able to frequently use both.

It is possible to rename SIMs. Go to Settings > Network & Internet > SIMs, and tap the pen 🖊️ icon in the top right hand corner of the screen.

DrJack60

treequell Ahhh, I went through everything but did NOT see the option there! That helps, a little. But it doesn't answer why it isn't actually accepting input to select one or the other for SMS.

As I look around online, the assigning of contacts to a particular SIM is listed as an Android feature, so apparently it is something that is removed in GoS. Renaming does help with identification; still cannot get the SMS app (standard one we all have) to actually work when I select "Ask every time". I am curious if others running dual SIMS would see if your install does the same thing if you choose this option.

No problems with "ask" here, works.
Merely cumbersome, particularly with using BT calling while driving - have to unlock phone and choose - as mentioned above.
Pixel 7 that is

DrJack60

d4f2 For phone, yes. But not for SMS, at least on my P7. Are you able to select & send text? Mine does nothing more than display both with long push. I'll go to Matrix & ask.

Follow-up: after selecting one of the other SIM & sending a message, suddenly on each thread it now has the proper acct noted in the reply area. It doesn't even ask for a selection, it is already attached. I can find no explanation but I am VERY pleased! What's interesting is that if I set it for "ask every time" neither works. But having selected a preference, it still defaults to the previously used acct. So there is still a bug, but it is trivial as it only requires selecting an acct one time then remembers which one to use 🤔

graphite-or-graphene I am using app called ACR Phone. You can assign SIM for a contact, it works. I paid them to get rid of ads. 5e is well deserved. My usage is the same - majority sim 1, sim 2 only sometimes, when i have to call back somebody from the office. I definitely dont want to disclose my personal number.

I have no info about the developers (whether they are 'good people' or somehow misuse my data).

fraphene

andrej567 I installed the app as well, but I can't find the option to assign a SIM per contact. Where were you able to set this up?

Thanks for the advice. I installed ACR phone and I can assign a specific Sim card to a contact like as required.

About privacy of user data, I hope Google checks an app's source code before publishing the app on Google play. I used to publish apps in Nokia store, and Nokia scrutinized source code before publishing.

Today operators of app stores like Apple's „App Store” and Google's „Play” (crazy name, BTW) check about danger for their platform, only.

The main thing is that money can be earned with an app and that it does not damage either the company's own platform or the reputation of the app store.
Whether the buyer is cheated or not plays a subordinate role.

If this wasn't the case, hundreds of torch apps or call filter apps wouldn't even exist because they either don't work at all or have unwanted additional functions.
