For example, AT & T explains that eSIM activations are delayed later in the year due to technical issues, partly related to Visual Voicemail.
According to an AT & T business manager who spoke with MacRumors stores have been told that AT & T does not support dual-SIM or eSIM at the present time, with stores recommended not to sell eSIM cards to customers .
Verizon and T-Mobile will not support eSIM currently, according to company spokesmen who spoke with PCMag . T-Mobile said that eSIM support is in work and will be available "when the software is ready" without timeline. Verizon, meanwhile, said that eSIM will be available after some kinks have been prepared.
It is also worth noting that Verizon customers should not activate eSIMs from other companies at this time due to performance issues. As mentioned by PCMag when a physical Verizon SIM is relegated to a "secondary" position of an eSIM from another company, the Verizon connection is downgraded to the 2G CDMA network.
Verizon says that it is working with Apple to resolve this issue, allowing customers to use eSIM without a result hit.
"Wireless customers will be able to activate Verizon service eSIMs as soon as we are sure that you will be able to get the great, high-quality service you expect from us on both your primary and secondary lines. A Verizon customer and you enable another carrier service on iPhones eSIM, your Verizon service will be degraded due to the current software configuration.
"Based on our discussions with Apple, we believe that these concerns will be resolved quickly and you should be able to add our amazing Verizon service to your secondary line before the turn of the year. Until the secondary line can deliver Verizon's full suite of speech and high speed data services, we will not activate the Verizon service on any eSIM, including our own customers 'iPhones with dual SIM features, as well as iPhones on competitors' networks. "
The fourth major US operator Sprint is not on Apple's list of operators who will implement eSIM support, but Sprint has said that it will add support at some point.
eSIM or digital SIM card is a non-physical SIM card slot that merges with the physical SIM card in iPhone XS XS Max and XR to enable dual-SIM dual standby, a feature that Allows iPhone users to get two phone numbers available at once.
With dual-SIM support, iPhone users can easily switch between the two phone numbers and facilitate the need for a second phone or SIM swap for work and travel.
While eSIM support is not available from major U.S. carriers, it is available in other countries around the world. Apple has a list of all carriers that support eSIM functionality on its website.
On Apple's website, eSIM support for AT & T, Verizon and T-Mobile "Comes later this year," suggests that the three carriers aim to launch the feature by the end of 201
