If you've ever wanted two phone lines on a device, Apple's new Dual SIM Dual Standby technology can be a live switch. It will make it very convenient to have two phone numbers on a phone – one for business, another for personal use.

iPhones have always had a "plastic" SIM card – until now.

Apple released October 30 Apple iOS 12.1 and enabled support for its eSIM technology – enabling customers to enable additional lines – on iPhone XS iPhone XS Max and iPhone XR (outside China). However, Verizon, AT & T, and T-Mobile do not support eSIM immediately due to issues that include "impaired" service and visual voice messaging issues, according to CNET and MacRumors reporting. [19659000] Verizon, AT & T and T-Mobile do not tell support eSIM until the end of 2018

It is apparent that Apple and most US operators are still working through kinks to distribute dual-SIM via eSIM. And although it will not be the deciding factor for most phone buyers this year, Apple's support marks an important step closer to the mainstream for dual SIM phones. Below is an enlargement of what we currently know about Apple's take on dual-SIM and eSIM – and what it means for the three 2018 iPhones.

Note: The information below presents our current understanding of a developing technology. If you buy an iPhone XS, XS Max or XR to take advantage of dual-SIM and eSIM technology, you must purchase an unlocked phone (see below). Check with your supplier before making a purchase.

What does Apple's dual SIM message mean?

With 2018 iPhones, you will have two different phone numbers on the same phone. You can make and receive calls and send and receive texts on any line.

Why would I like a dual SIM phone?

There are two major benefits. You can have two different phone lines – say one for business and another for personal use – without wearing two phones. And while traveling internationally, dual SIM cards make it easier to add a local plan to your phone to avoid expensive international roaming and data costs.

Read: Why do you want a dual SIM phone [19659022] So, do iPhones have both an eSIM and a plastic SIM?

Yes. The new iPhones have a traditional plastic nano-SIM, the well-known hardware-based SIM chip that identifies you for your carrier network and an eSIM, the newer software-based equivalent.

And here's the big thing: ESIM can accommodate multiple phone numbers – which you can add, delete and configure directly from your iPhone's settings. In contrast, a plastic SIM must be physically removed and replaced.

In theory, when eSIM technology is often supported by carriers in the United States and internationally, Apple could completely outdone plastic SIM. Currently, by providing 2018 iPhones both a plastic SIM and eSIM, Apple covers all bases.

What is Dual SIM Dual Standby?

Apple's recording of dual SIMs is called Dual SIM Dual Standby. This means that the new iPhones can handle two phone lines simultaneously. Calls that enter a line call the phone and you can easily call and send texts from either row without reconfiguring settings or replacing SIM cards .

Note that you will not be able to send and receive data on both lines at the same time. If a line is on a call, incoming calls to the second number will be sent to the voicemail.

How does eSIM differ from Apple SIM?

Originally called Apple SIM, the first version of Apple's program-based SIM card appeared on LTE-compatible iPad and Apple Watch Series 3. We believe the basic technology is the same, but iOS 12 has introduced user interface improvements.

Note! Verizon, AT & T and T-Mobile are not currently supporting eSIM .

Can I add lines from different carriers?

Yes. Apple says you can add rows from two different carriers – if your iPhone is unlocked . And this is the big catch. If your phone is unlocked, both plans must be from the same operator. And if a CDMA operator – like Verizon, Sprint, US Cellular, Boost and Virgin – gives your first SIM card, your other SIM card will not support CDMA.

Note! Verizon has been alerted Current customers that activate another operator's service on an iPhone eSIM will result in worsened service due to the current application configuration.

Can I use eSIM on a locked iPhone?

When you buy an iPhone directly from Apple, online or in an Apple Store, it's unlocked – which means it can be configured for and enabled on any carrier's network (eg AT & T, Verizon, Sprint). A Genius adds an AT & T SIM, for example, activates the phone on AT & T's network, and you are looking for the contests.

But when a phone is locked, your possibilities are very limited. As my colleague Maggie Reardon explains, "A locked phone has a program code on it that prevents you from using it on another network. An unlocked phone also does not have the software lock on it or someone could get a code that unlocks the software. device is unlocked you can pop out the SIM card and insert another SIM card and get service. "Most operators require you to pay full for your phone before unlocking it and other restrictions may apply. (AT & T Unlock Portal provides a checklist of requirements to unlock the phone and switch to another operator.)

An unlocked phone with a plastic SIM needs a new plastic SIM to switch to a new operator. An eSIM, on the other hand, can accommodate multiple SIM profiles from multiple carriers. Up to now, eSIM has not received much support from operators, which are understandably cautious to make it easier for customers to activate another operator's service.

When will Apple start his eSIM feature?

Apple enabled the eSIM feature when it released iOS 12.1 on October 30th. But US carriers have called up the time to support eSIM while working through a number of technical issues. Reports suggest that the feature will be fully used since 2018.

How do I install eSIM on the new iPhone?

Owners of a 2018 iPhone will be able to access eSIM via iPhone settings. According to Apple VP Phil Schiller, you can use the phone's camera to scan a carrier QR code, which starts the process to activate a second row. Then iOS lets you choose a default line for calls and messages, choose a label for each line, and so on.

Apple has listed step by step instructions to create an eSIM on its support site.

Can an eSIM be overwritten?

An eSIM can be overwritten and accommodate a phone plan from all operators that support the technology.

Which carriers support eSIM technology?

Apple says that eSIM operates in 16 countries. In the United States, AT & T, T-Mobile and Verizon currently work on implementing the technology. (A Sprint spokesman assured CNET that the company will support the feature in the near future.) Internationally, participating operators currently include EE, Vodafone, Truphone, Bell, GigSky, Jio, Airtel and Deutsche Telekom.

At September 12, Keynote said Apple VP Phil Schiller that more carriers would support in the fall and next year.

Are there other phones with dual SIM technicians? And does not Google Pixel 2 have an eSIM?

There are plenty of phones that can hold two SIM cards, but most are not available in the US, but only a few so far that support eSIM. Google Pixel 2 has an eSIM – but it's primarily for use with Google's Project Fi mobile service.

Do I need approval from my main provider to add a second phone number?

No, you do not need permission or permission to add a second phone number. In fact, the big upside side of eSIM is that you do not even have to go to a store to activate the second line – it can all be done remotely.

Apple announced a special edition of the new iPhones for China, which will have two plastic SIM slots instead of eSIM technology. According to Neil Shah, which covers mobile technology for Counterpoint Research, dual-SIM technology is popular in China – but few bearers have built up support for eSIM technology.

Will we see more eSIM phones in the US?

Probably. After all, Apple often puts the trends. Will Stofega, covering cell phones for IDC, bearers have been careful with eSIM, and feared that it could lead customers to jump from plan to plane. But he points out that a new international standard established in June 2016 may pave the way for a greater adoption of eSIM in the US and abroad, especially if carriers realize all the benefits of selling and delivering telephones on distance activities that must be
