Dual SIM Card

Dual SIM provides the convenience of having two phone numbers on a single iPhone. You can have separate personal and business numbers, or add a second line when travelling internationally.

With Dual SIM, you can have two phone numbers to make and receive voice calls, and to send and receive text and multimedia messages (SMS and MMS).

On iPhone XR, iPhone XS and iPhone XS Max, Dual SIM service is offered through a combination of a physical SIM and an eSIM. An eSIM is a digital SIM that lets you activate a cellular plan without having to use a physical SIM card.

The two phone numbers can be on the same account, on different accounts, or from different carriers (for example, one line from Lucky Mobile and one line from an international carrier).

  1. Check that your iPhone is updated to iOS 12.1.1
  2. Go to Settings > Cellular > Add Cellular Plan.
  3. Tap the Add Cellular Plan button.

Will Lucky Mobile support the Dual SIM functionality on the iPhone XR, iPhone XS and iPhone XS Max?

Yes, Lucky Mobile supports Dual SIM functionality on these devices. To learn more about setting up and using an eSIM with your iPhone, visit the Apple support page.

What Plans are available for the two lines?

Both lines can be on any Lucky Mobile plan. You can choose to have a voice and text plan or a voice and data plan on either line.

I’m a Lucky Mobile customer with two phone numbers on two separate devices. Can I move one of my phone numbers to an eSIM card so I can have both my phone numbers on my one iPhone XS, iPhone XS Max or iPhone XR?

This is not possible at this time.

How do I tell which phone number I’m using?

The default labels for each of the lines are named “Primary” and “Secondary” respectively. In the “Cellular Settings” of your iPhone, you can create your own labels for each line. For example, you can name your lines “Work” or “Personal” or something else.

When you make and receive calls, as well as send and receive text messages, the first letter of each label will pop up as an indicator so you can identify each line by its respective label.

If I have a data feature on both lines, which data feature will I use and therefore be billed for?

Both lines can support data features; however, you can only access one line’s data feature at a time. Therefore, you cannot access both data features simultaneously.

At any one time, your data usage will come out of the data feature you have defaulted to in your iPhone’s “Cellular Settings”. You can then toggle to your other data feature within those settings. For example, during work hours, you can use the data from your “Work” line, and after work you can switch to your “Personal” line. For more details, please see the Apple support page.

Can I use data while on a call?

Yes, but only one line can use data at a time.

If “Cellular Data Switching” is turned off (in settings).

  • You can only use data while on a call made or received on the same line that you have selected for your data usage. For example: if you are on a call on Line 1 and your data is set to Line 1 as well, you can use data while you’re on the call. However, if you are on a call on Line 1 and your data is set to Line 2, you cannot use data while you’re on the call. For more details on how to set up your voice and data preferences, please see the Apple support page.

If “Cellular Data Switching” is turned on (in settings).

  • You will be able to use data during a call no matter what line your data or voice is set to. For example: if you are on a call on Line 1 and your data is set to Line 2, you will be able to use data from Line 2 while you’re on the call on Line 1.

You can also access Wi-Fi on either line regardless of which line you have selected for your data usage.

How will I be billed for voice and messaging?

Voice and messaging are calculated according to the rate plan of the line used for each activity. With Dual SIM, you have the choice of which phone number to use for each call and text.

Can both lines be connected to the network at the same time?

Yes, both lines are connected to the network at all times. However, when you are on a call on one line (e.g., Line 1), the other line (e.g., Line 2) automatically goes on standby mode. This means, if someone tries to call you on Line 2 when you are on a call on Line 1, you will not receive a call waiting notification for the incoming call. Instead, that call will be directed to your Line 2 voicemail.

Please be mindful that this has implications for 9-1-1 calls. If you are in a situation where you need to call 9-1-1 from Line 1, your phone then disconnects and you get another call on Line 2, you will not receive a notification that the 9-1-1 operator called you back on Line 1.

Will E9-1-1 and T9-1-1 work on both lines?

Both lines have the capability to dial 9-1-1. Where E9-1-1 is available, the caller’s number and approximate location will be provided, regardless of the line used.

For T9-1-1, each line needs to be registered separately. Register for T9-1-1.
