Which phone has Dual SIM and eSIM? ›

All iPhone models that support eSIM can have multiple eSIMs and use Dual SIM with two active SIMs at the same time. You can use Dual SIM by using a physical SIM and an eSIM. iPhone 13 models and later also support two active eSIMs. iPhone models without a physical SIM tray support two active eSIMs.

Dual SIM gives you the convenience of having two phone numbers on a single smartphone equipped with dual SIM with an eSIM. If you have a dual SIM phone with an eSIM, you can use Ubigi eSIM services. You can for instance have separate lines for personal and business purposes, or different lines for different countries.

An eSIM works the same way as a traditional SIM, but you don't need any physical SIM card anymore. The eSIM is welded in your device and activated over the air.

Like a traditional SIM card, the eSIM stores data that's needed for your device to use the EE network. Unlike a SIM card, an eSIM is downloaded onto your device. These phones are also 'Dual SIM'. They have two SIM slots meaning that you can have two numbers and two different plans on the same phone.

Management Complexity: Keeping track of contacts, messages, and calls for two numbers can be confusing and time-consuming. Network Limitations: Some phones may not support using 4G or 5G simultaneously on both SIMs, potentially reducing internet speeds or call quality.

An eSIM (embedded SIM) is a form of SIM card that is embedded directly into a device. Instead of an integrated circuit located on a removable SIM card, typically made of PVC, an eSIM consists of software installed onto an eUICC chip permanently attached to a device.

The answer is generally no. When you install an eSIM, it doesn't directly alter your phone number. Your phone number remains the same, and you can continue to use it as you normally would.

Each SIM Card whether it is a eSIM or the physical SIM Card can only have one mobile number for each SIM Card. The eSIM will have a different mobile number, and so would the physical SIM Card. Using the eSIM or physical SIM Card on a smartphone can only be done with the same device (Two mobiles number with one phone).

If your device has more than 1 SIM and is DSDS-capable, you can have multiple numbers on 1 phone (e.g., your business and personal numbers on the same phone). With DSDS, each SIM can be activated on a separate mobile phone number.

Changing devices might not be straightforward

If you are using an eSIM and you need to change phones, chances are that you will need to contact your local provider to enquire how to transfer your eSIM. While Android and iOS have eSIM transfer tools, not all carriers allow an eSIM transfer.

Can you make phone calls with Ubigi eSIM? ›

So, you can not make phone calls with Ubigi eSIM data plans but you can use iMessage and your favorite VoIP applications such as Skype, FaceTime, WhatsApp, Viber, Facebook Messenger, etc. By using these VoIP apps, you will be able to make calls and send text messages.

However, it doesn't support phone calls and text, which can be a major letdown for some users. Plus, its mobile app is a bit clunky. Overall, Ubigi is a great eSIM service, but it's a few steps behind others like Saily and Airalo.

Dual SIM models allow you to use two SIM cards in one device. This is handy if you have separate phone numbers for work and home or if you would like to use a local number while keeping your original number active when in a foreign country.

If you've noticed new, unfamiliar numbers on caller ID but the same voice responds, they might be using another SIM. Network Fluctuations: Dual-SIM phones often show two signal strength indicators. Notice if there are fluctuations or changes in the network icon(s) on their phone.

Can I switch off one SIM in a dual SIM phone? Yes you can..go to settings-sim card management-standby sim-then you can turn off one sim out of two.

There are different ways you can get dual SIM functionality depending on what phone you have and which SIM combo you are using (e.g. nano-SIM and eSIM). iPhones use an eSIM and nano-SIM combination while Android phones may use the nano-SIM/eSIM combination or two nano-SIM cards.

Each SIM Card whether it is a eSIM or the physical SIM Card can only have one mobile number for each SIM Card. The eSIM will have a different mobile number, and so would the physical SIM Card.
