Nokia 3310 3G 用戶指南: 更有效地運用兩張 SIM 卡 (雙 SIM 卡手機)

Get the most out of the two SIM cards (dual SIM phones)

Your phone can use two SIM cards, and you can use them for different purposes.

Select which SIM card to use

Select Menu > > Connectivity > Dual SIM.
To choose which SIM to use for calls, select Preferred SIM for calls, and select SIM1 or SIM2.
To choose which SIM to use for messages, select Preferred SIM for messages, and select SIM1 or SIM2.
To choose which SIM to use for mobile data, select Mobile data connection, switch Mobile data on, and select either SIM1 or SIM2.

Forward calls between your 2 SIMs

Get the most out of your 2 SIM cards. If you forward your calls between your SIMs, when someone calls you on one SIM while you’re having a call on the other, you can manage your calls from both SIMs just like with only one SIM.

Make sure you have 2 SIM cards inserted in your phone.

Select Menu > > Connectivity > Dual SIM > SIM numbers.
Type in the numbers of your both SIMs and select Save.
Scroll up to Forward calls, and select Between two SIMs, From SIM1 to SIM2, or From SIM2 to SIM1.
