However, the transition to eSIM has not been friction free. While smartphones, wearables, and IoT hardware are adopting eSIM rapidly, the customer experience is inconsistent and carriers face backend complexities that are often invisible to end users.

The next phase of eSIM growth depends on solving these friction points.

The Core Challenges Slowing eSIM Adoption

Below are the most prominent challenges that mobile operators, device manufacturers, and the broader industry must address.

1. Fragmented Activation Processes

One of the biggest barriers to mass adoption is the lack of standardization in activation flows. Physical SIMs offer a universal experience. Users insert a SIM and begin using the device immediately.

With eSIM, the experience varies widely across:

• Different operators
• Device types
• Operating systems
• Regions
• Retail vs online onboarding

Some carriers require manual QR code scanning. Others require a dedicated app, a special webpage, or an in store provisioning process. Enterprise IoT devices often need a separate remote SIM provisioning platform with complex credentials.

This fragmentation confuses customers and discourages those who are not highly tech savvy. Many users still believe eSIM activation is more difficult than simply inserting a physical SIM, even though this is not always true.

What the industry must address

• Create unified activation standards across carriers
• Introduce intuitive, app based onboarding that works globally
• Offer clear step by step user guidance during provisioning
• Ensure backward compatibility with legacy workflows while optimizing for the future

A smooth, consistent activation experience is essential for future growth.

2. Limited Carrier Support in Some Markets

Despite rapid adoption in North America, Europe, and parts of Asia, many markets still lack widespread eSIM support. Some operators hesitate to roll out eSIM due to perceived churn risk, backend cost concerns, or limited consumer awareness.

In developing markets, carriers often prioritize physical SIM cards because:

• They generate significant revenue through SIM distribution networks
• Retail agents rely on commissions from SIM sales
• Infrastructure investment is needed to support eSIM provisioning

The result is a patchwork of availability that complicates global device manufacturing and international roaming.

What the industry must address

• Broader public education about the benefits of eSIM
• Affordable provisioning solutions for smaller carriers
• Incentives for operators in emerging markets to adopt digital SIM technology

To achieve true global interoperability, eSIM support must be universal.

3. User Confusion and Lack of Awareness

Even in markets where eSIM support is strong, many customers still do not fully understand what eSIM is or how it works. Surveys show that consumers frequently express concerns about:

• Losing access to their phone number
• Difficulties switching carriers
• Losing their eSIM profile during device resets
• Managing multiple profiles
• Transferring eSIM to a new device

This uncertainty creates hesitancy. Customers who are accustomed to the physical SIM card often view eSIM as an unfamiliar and potentially risky technology.

What the industry must address

• Develop simple, approachable consumer education
• Explain eSIM management in plain language rather than technical terms
• Provide visual guides and onboarding tutorials inside devices
• Reduce jargon such as “profiles,” “SM DP server,” and “remote provisioning”

When consumers understand eSIM better, their trust and willingness to adopt the technology will increase dramatically.

4. Device Transfer and Switching Complexities

Switching an eSIM profile from one device to another is one of the most commonly reported pain points. With a physical SIM card, users simply remove the card and insert it in a new device. With eSIM, they must:

• Request a new profile
• Scan a new QR code or use a transfer feature
• Confirm identity again
• Sometimes contact customer support

Although Apple and Google have introduced device to device eSIM transfer features, support varies by carrier and region. Enterprise devices often lack consumer friendly transfer processes altogether.

What the industry must address

• Universal support for secure, automated device to device transfers
• Instant transfer options for both consumers and enterprises
• Smarter fallback mechanisms when a device is lost or damaged
• Standardized APIs for seamless eSIM migration

The industry must ensure switching devices becomes as easy as it was with physical SIM cards. Until that happens, user frustration will persist.

5. Lack of Full Multi Profile Flexibility

One of the greatest promises of eSIM technology is the ability to host multiple carrier profiles on a single device. In theory, this allows:

• Travelers to switch to local plans instantly
• Dual connectivity for work and personal lines
• IoT devices to move between carriers automatically
• Businesses to manage connections remotely across regions

However, in practice:

• Many carriers limit the number of profiles
• Certain devices restrict simultaneous profile usage
• Some mobile operators charge extra fees for eSIM usage
• Roaming and local carrier interchangeability is still problematic

Until multi profile flexibility is universally supported, the full value of eSIM cannot be realized.

What the industry must address

• Remove barriers to holding multiple active profiles
• Simplify carrier switching for travelers
• Enable truly automatic carrier selection based on coverage and cost
• Allow seamless fallback connectivity when one profile experiences issues

A future where devices intelligently manage connectivity is only possible if multi profile support expands industry wide.

6. Backend Infrastructure and Operational Burdens

Many carriers struggle with the backend complexities of eSIM provisioning. Managing physical SIMs is straightforward. eSIM systems require investment in:

• SM DP and SM DS platforms
• Authenticated provisioning systems
• Secure remote management infrastructure
• Device binding and Cloud based profile deletion
• Fraud detection and identity verification systems

For smaller operators, the cost of implementing these systems is a significant barrier. Even large operators face challenges related to system performance, integration with legacy CRM and billing systems, and compliance with GSMA standards.

What the industry must address

• More affordable eSIM platform services for small operators
• Standardized APIs for provisioning and lifecycle management
• Cloud native provisioning platforms with scalability and automation
• Better visibility into active profiles and device status

The entire ecosystem benefits when carriers can focus on customer experience instead of backend complexity.

IoT is expected to be one of the biggest beneficiaries of eSIM technology, but adoption has been slower than anticipated. IoT deployments face unique challenges:

• Large scale provisioning for thousands or millions of devices
• Long device lifespans that require easy long term profile management
• Devices deployed in remote or hard to access locations
• Limited user interfaces for scanning QR codes or entering credentials
• Dependence on M2M eSIM standards that differ from consumer eSIM flows

The result is a fragmented landscape where some IoT devices use consumer eSIM provisioning, others use M2M remote provisioning, and many use hybrid systems.

What the industry must address

• Improve M2M remote provisioning standards
• Offer unified platforms for managing IoT connectivity
• Enable automatic carrier switching for global IoT fleets
• Increase support for low power devices and LPWAN technologies

IoT growth depends heavily on smoothing the eSIM experience at scale.

8. Interoperability Gaps Between Devices and Carriers

True eSIM success requires universal interoperability. Although GSMA standards help, real world scenarios reveal gaps:

• Some carriers do not support device to device transfers
• Certain devices restrict eSIM activation to proprietary apps
• Wearables use different provisioning workflows from smartphones
• Enterprise devices may require special configurations
• Carriers sometimes block eSIM activation for non approved devices

These inconsistencies complicate the user experience and increase support burden.

What the industry must address

• Strengthen enforcement of GSMA interoperability requirements
• Ensure all major devices support consistent provisioning methods
• Enable cross carrier transfers without special steps or delays
• Improve compatibility testing for manufacturers

True interoperability will make eSIM adoption frictionless across borders and devices.

9. Security and Fraud Concerns

Although eSIM is more secure than a physical SIM, carriers still face concerns such as:

• Fraudulent profile activation
