When Apple unveiled iPhone XS, iPhone XS Max and iPhone XR, it came up with many great features and among these was the Dual SIM functionality. The iPhone XS series is the first from Apple to feature Dual SIM technology but just like the company does every time, its implementation is widely different from everything else in the market. And the way it is implemented, the Dual SIM feature of the iPhone XS and iPhone XR might not even work in most parts of the world.
iPhone XS, iPhone XS Max and iPhone XR Limitations
- To connect your iPhone XS or iPhone XR to two different network operators, you must own an unlocked device. On a carrier locked iPhone, you will be limited to using two SIMs from the same operator.
- If you use a CDMA SIM in the first slot, you cannot connect to another CDMA network with the secondary SIM.
- Finally, the dual-SIM feature on the iPhone XS and iPhone XS Max is not enabled as of now. It will be enabled with the upcoming iOS 12.1 update.
Easiest Way to use Dual SIM on iPhone XS, XS Max and iPhone XR
Now and as you know the dual SIM limitations it's time to start activating it:
STEP 1: Scan the eSIM'S QR code by either downloading your carrier's official app or use a QR code generated by them. In order to do this simply go to Settings ---> and navigate to cellular and tap on Add cellular plan and start scanning the QR code provided by your carrier.
STEP 2: Label the two SIM Cards
To help make it easier to manage multiple SIMs on your iPhone XS or iPhone XR, it is important that you label them. If you have two separate numbers for Personal and Business or for Business and Travel, you can label them accordingly. Your iPhone will refer to your SIM cards via this label so this is important. If you want, you can also enter a custom label name.
You will be automatically prompted to label the numbers after initially setting up dual-SIMs on your iPhone.
You can also do it later on from Settings -> Cellular, select the SIM whose label you want to change followed by the Cellular Plan Label option.
STEP 3: Set a default SIM Card
Make sure to set a default number as this will be the one used by iMessage and FaceTime for sending/receiving messages. Your default line will automatically be automatically used for cellular services, mobile data, phone calls, and SMS. You do have the option of using your secondary number for mobile data purposes, while your primary number will be used for voice, SMS, iMessage etc.
That's it now you have successfully set up dual SIM cards on your iPhone.
How to check the signal strength of your SIMS
Probably you want to check out the signal strength on your iPhone to see if the dual SIMs are working great without any weak signals. You will be able to see both the primary and the secondary SIM cards signals on the status bar above. The primary SIM will display its signal strength as usual, with the secondary SIM signal strength being shown right below it in the form of four dots as you can see below.
You can get a better idea of the signal strength and which carrier both SIMs are connected to by swiping down on the top right corner to access the Control Center.
How to switch between primary and secondary SIM for calls
By default, your iPhone will automatically use your primary number to call any contact or for sending an SMS. Alternatively, it will use the same number which you used to call a contact the last time around. So, if you called someone using your secondary number, your iPhone will automatically call that contact using your secondary number henceforth.
To switch between numbers from the Phone app, simply enter the phone number and proceed to tap your primary number’s label you see at the top and tap on the other number to switch to the second line.
So what do you think guys ?
