Frequently Asked Questions
Can I use two eSIMs simultaneously instead of physical SIM + eSIM? Most current devices support only one active eSIM alongside a physical SIM. Some newer models are beginning to support dual active eSIMs, but this varies by manufacturer and model.
Do both SIM lines work simultaneously for calls and data? Yes, you can receive calls and messages on both lines simultaneously. However, only one line can provide data at a time, though you can switch between them easily.
Can I use different carriers for each SIM type? Absolutely. You can use any combination of Saudi carriers (STC, Zain, Mobily) or mix local carriers with international eSIM providers for optimal coverage and pricing.
Will dual SIM + eSIM drain my battery faster? Dual SIM usage typically has minimal impact on battery life with modern smartphones. However, poor signal strength on either line may increase battery consumption as the device works harder to maintain connections.
Can I transfer my existing number to eSIM while keeping another number on physical SIM? Yes, most Saudi carriers support number porting to eSIM. You can port your existing number to eSIM while activating a new or different number on your physical SIM.
