Dual SIM mobile phones allow users to use two SIM cards in a single device, providing them with the flexibility to switch between multiple phone numbers or carriers. These phones are particularly useful for international travelers or people who need separate numbers for work and personal use. Dual SIM mobile phones also provide cost savings by allowing users to take advantage of different data or call plans from different carriers. https://www.mobileciti.com.au/mobile-phones/dual-sim-phones
