Prepare to use eSIMs with Apple devices
Cellular activation requires either a SIM or an eSIM provided by the carrier. eSIMs are preferred for a number of reasons, but your local carrier may not support them at the scale your organization needs. Carrier selection should also take into account coverage for where users live, work or attend school, as well as any location where devices are initially configured.
eSIM support
If your cellular carrier supports eSIM Carrier Activation, eSIMs can be automatically installed on an iPhone (with iOS 16 or later) or iPad (with iPadOS 16.1 or later):
With no mobile device management (MDM) solution required.
During device setup using Automated Device Enrollment with Apple School Manager or Apple Business Manager.

eSIM security benefits
eSIMs are exceptionally secure and tamper resistant. They can’t be cloned or modified, and they’re designed to operate only on a specific device. By design, the GSMA eSIM specification SGP.21 restricts eSIM profiles from being exported from one eUICC to another.
With a physical SIM, someone can quickly steal a user’s SIM (which contains the user’s phone number). This allows SMS communication to that number, such as receiving one-time passcodes or personal identification numbers. With an eSIM, this isn’t possible.
To prevent additional lines of service from being added to a user’s iPhone, you can use MDM and the AllowESIMModification restriction to prevent the addition or removal of eSIMs.
All iPhone 14 or later models sold in the United States, and all iPad Pro (M4) and iPad Air (M2) models are eSIM only. This provides an extra layer of protection because you can’t physically remove or replace an eSIM. If the iPhone or iPad is lost or stolen, its much harder to activate it on another line.
Carrier selection
All iPhone devices, and some iPad devices, have cellular coverage. To make best use of that coverage when planning deployment, make sure you have the right carrier for your needs.
Because eSIMs are software based, they afford much more deployment flexibility and are also easier to secure; administrators can trigger eSIM installation remotely and restrict a user’s ability to remove it from their device. If there’s a need to change the cellular carrier for devices after they’ve been deployed to users, a mobile device management (MDM) command lets you do that without any user interaction. There are other advantages to using an eSIM. For example, if permitted, the user can also change to use the previous eSIM in Settings > Cellular.
When selecting a carrier, ask the following:
After an agreement is signed, what is the time period to create and make available the eSIMs so they can be assigned to supported iPhone and iPad devices?
Does your carrier support eSIM Carrier Activation for automating eSIM installation?
Does your carrier allow users to transfer eSIMs between iPhone and iPad devices?
What is the URL for your carrier’s eSIM server (known as an SM-DP+ server)?
Ensure that access to the carrier’s eSIM server is available through firewalls.
Use the carrier’s eSIM server hostname when installing eSIMs using MDM.
Regarding cellular coverage and capacity, can the carrier provide a survey of cell towers close to where the devices are provisioned and where remote learning may be taking place?
Note: Because carriers may be sensitive to the number of devices simultaneously queuing for eSIM provisioning, many of them request that automated provisioning events be communicated to them.
