Dual SIM

[mawallace]

I've been trying to understand how Dual Sim works on S10

i. Can you set which one is the 'primary' SIM?

ii. Will it switch to the SIM with the strongest data signal - or do you have to do this manually. or can it be programmed to switch across when there is no data signal on the 'main/ SIM care.

Re: Dual Dim

I don't know about 1 (but possibly).

2. It's dual-standby. One SIM is working, while the other one isn't. You have to manually switch. (Nearly all dual-SIM phones work that way. Dual-active means 2 radios, and that can get expensive to the manufacturer [and passed on to the user], and most people don't know the difference until they keep missing calls on the not-active SIM.)

You're mostly wrong about how dual SIM standby works. The only time you can't get a call or text from SIM 2 is when you're on a call on SIM 1 and vice versa. When the phone is just sitting there, both SIMs are in standby and when you get a call the SIM it came through on becomes active. You never have to switch manually, except for the SIM you want for data which doesn't automatically switch.

Now, here's some screenshots that should be helpful...

EDIT: Apparently I have to do this one at a time.

This is the default text app, as you can see, you pick which soo to send with. Other messaging apps work similarly.

This is the default dialer app. As you can see you can select which SIM to call from. Other dialers work similarly.

Re: Dual Dim

This is the SIM picker in the notification shade. I find it to be completely useless and you can't get rid of it. One of Samsung's many poor design decisions.

You're talking about choosing the SIM to send with. The OP and I were talking about which SIM will receive calls in a dual-standby phone. If you lost the signal on the active SIM, the phone won't "switch to" the standby SIM, it will act just like a single SIM phone when you lose the signal. (You can still use whichever SIM you choose to send or call with.)

No.

Obviously if you lose signal on SIM 1, you can't receive calls on SIM 1, but you CAN receive calls on SIM 2 (assuming it has signal).

If both SIM cards have signal and someone calls you on SIM 1, your phone will ring. If both SIM cards have signal and someone calls you on SIM 2, your phone will ring.
