What is Reddit's opinion of Dual SIM Selector?

From 3.5 billion Reddit comments

With this app you can set the SIM card to be used for each contact and choose to always use this card on this contact or to always ask.

I don't have DS so I can't test it, but that should be what you're looking for. Note that this is a 7 day trial and it then is €3.99 (or whatever price & currency it will be for you)

> I don't think you can set a certain SIM for certain accounts...

I did not research the subject but know that there are some automatic dual sim apps that are binding phone numbers and/or contacts you select to SIM 1 or 2 & will automatically select it according to your choices like Dual SIM Selector for example.

I never tried them.

I have been using this app since my dual sim S7, works perfectly on my S9 too

It's a shame we need an app as my dual SIM LG G4 had something like this built in.

Dual SIM Selector has worked well for me with my OnePlus 3T. When you dial a number it asks which SIM to use, then will remember it for future calls.

You might want to check out the app Dual Sim Selector. I've tried it a bit so far and you can assign one of your sim cards to a contact/group/number.

Dual SIM Selector has solved all of my dual SIM issues.

This the pro version of this app:
