Dual Sim Caller: Dialer

Tired of picking a SIM every time you call? Dual Sim Caller is the dual SIM dialer and dual SIM manager that remembers which line to use — per contact, number, or group.

Set your work SIM for colleagues and your personal SIM for family once, then call without the popup. Bulk-assign defaults across your address book, and let smart routing handle the rest when your schedule, car mode, or Bluetooth setup would otherwise get in the way.

What you get
• Dual SIM phone dialer & SIM manager with keypad, recents, contacts, and in-call screen
• Default SIM / automatic SIM selection per contact or number — including bulk assignment
• Custom SIM names, colors, and ringtones so each line is obvious
• Smart rules: time of day, car/Bluetooth safe mode, wrong-line warnings
• Spam hints, block list, and quick tools for everyday calling

Built for people who run two lines on one phone: work and personal, home and travel, local and roaming. Dual Sim Caller works as your default Phone app so the right SIM sticks when it matters.

Try free for 3 days, then unlock premium once — no subscription.

Privacy note: Dual Sim Caller needs phone and contacts access to place calls on the SIM you chose and to save your preferences. Your call routing stays on your device.
