iPhone users wishing to benefit from using two or more phone numbers from a single Apple phone may be interested in knowing that multiple and dual SIM iPhone support is available using digital SIMs. Using two or more numbers on a single phone is useful if you would like to keep your personal calls separate from your business. Using eSIM a digital SIM platform allows you to add additional cellular or data plans without having to use a second physical SIM card. As physically adding dual Sim cards to the iPhone as impossible because Apple has only equipped the iPhone with a single SIM card slot since its launch.
Multiple SIM support is possible on the iPhones using either Dual SIM with either two active eSIMs or a nano-SIM and an eSIM on the iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 mini. Or you can use a multiple SIMs with a nano-SIM and an eSIM with older Apple phones such as the iPhone 12, iPhone 11, iPhone XS, iPhone XS Max and iPhone XR.
Once setup, the ability to use multiple or dual SIM on iPhone allows you to add a local data plans when travelling outside your prime country, enabling you to save money on roaming charges. You can also use separate SIMs for voice and data plans, allowing you to benefit from cheaper data allowances when creating mobile hotspots. Allowing you to connect your laptop, tablet or family devices directly to your iPhone.
If you would like to use 5G with Dual SIM on the older iPhone 12, you will need to have the iOS 14.5 operating system installed or later versions. If you are using dual SIMs with iOS 13, your phone can use one cellular data network at a time. Although with iOS 13 and above, iPhone users can make and receive voice and FaceTime calls as well as send and receive messages using iMessage, SMS, and MMS.
To enable Dual Sim support on your iPhone, you will need iPhone XS, iPhone XS Max, iPhone XR, or later with iOS 12.1 or later and be signed up with a cellular network carrier that supports eSIM technology. If you are unsure whether your network supports eSIM, a quick call to their support line or search of their website should provide the information you need.
Dual SIM support for unlocked iPhones
It is worth noting that if your iPhone is not unlocked, both your cellular network plans must be from the same provider. This becomes an issue if you are traveling to other countries where cellular providers may differ. If your iPhone is unlocked, then you can use two different carriers on the same handset. Apple also states that if a “CDMA carrier provides your first SIM, your second SIM won’t support CDMA”. For more clarification, it is best to discuss this with your network provider or if you are using a business iPhone, contact the administration team.
Setup eSIM on your iPhone
Apple allows you to store more than one eSIM on your iPhone, but you can only use one at a time. Requiring that you switch from one to the other. This is accomplished by going to your Settings app and selecting either Cellular or Mobile Data and selecting the plan you would wish to use. To help with quick and easy switching between dual SIM iPhone plans, we recommend labeling your plans. To change the name of each individual plan, go to Settings > select either Cellular or Mobile Data and then tap the telephone number of the plan you would like to rename and select Cellular Plan Label to type in your desired reference.
