Communication on offshore platforms: how eSIM solves the connectivity problem

Connectivity has always been one of the main challenges of the offshore industry. On oil platforms located far from the coast, keeping teams connected in a stable, secure, and economically viable manner requires a complex combination of technologies.

With the advancement of digitalization in the oil and gas sector, the demand for offshore mobility, real-time communication, and continuous access to mobile data on mission grows. In this scenario, solutions based on eSIM are beginning to gain ground as a complementary alternative for corporate operations at sea.

The advancement of esim Yesim also follows a global trend of digitalization of business communications, especially in remote and hard-to-reach environments.

The unique communication challenges on offshore platforms

Offshore platforms operate in extreme environments. Many are located hundreds of kilometers from the coast, such as in the Brazilian pre-salt or regions of the North Sea.

This creates specific connectivity challenges:

• limitation of conventional mobile coverage
• high cost of satellite communication
• difficulty of mobility between countries and operations
• need for constant access to corporate data
• communication between international teams

Moreover, onboard professionals frequently alternate between different regions and countries during operations, which increases the complexity of connectivity management.

In practice, companies need to balance:

• communication availability
• operational security
• cost control
• international mobility

The digital transformation of the offshore sector has also increased the need for real-time connected applications, including:

• monitoring systems
• operational communication
• technical reports
• corporate applications
• remote access to management platforms

Traditional solutions and their limits: satellite, radio, and roaming

Historically, communication on oil and gas platforms has primarily relied on satellite, radio, and international roaming.

While these are important solutions, there are operational and financial limitations.

Satellite

Advantages:

• coverage in remote areas
• global operation

Limitations:

• high cost
• higher latency
• complex infrastructure
• dependence on specific equipment

Offshore Radio

Advantages:

• quick operational communication
• reliability over short distances

Limitations:

• limited range
• does not solve modern mobile access
• low flexibility for corporate data

International Roaming

Advantages:

• initial ease

Limitations:

• high costs
• difficulty in corporate management
• coverage inconsistency
• dependence on local operators

In this scenario, companies have started to seek more flexible solutions to complement traditional connectivity.

eSIM for Professional Offshore Use — How It Works in Practice

The eSIM functions as a virtual chip integrated into the device, allowing digital activation of mobile lines without the need for a physical SIM.

In practice, this greatly simplifies international operations and environments with high mobility.

In the offshore sector, the eSIM can be used in:

• corporate smartphones
• operational tablets
• IoT devices
• mobile monitoring equipment

One of the main advantages is the quick switch between operators and international plans without the need to physically replace SIM cards.

This is especially useful for teams operating between:

• Brazil pre-salt
• Gulf of Mexico
• North Sea
• platforms in Africa and the Middle East

Benefits of eSIM for Offshore Companies

• remote activation of connectivity
• reduced logistics with physical SIM cards
• more flexible management of corporate lines
• simplified international mobility
• less reliance on traditional roaming
• support for multiple profiles on the same device

Another important advantage is operational agility.

Instead of relying on physical delivery of SIM cards or complex local negotiations, the company can provision lines remotely.

For IT and HR managers looking to test corporate connectivity solutions, platforms like yesim offer simplified implementation and digital management.

yesim.app as a Complementary Tool for Offshore Teams

The yesim.app functions as a complementary solution for international corporate communication, especially in operations that require constant mobility.

The platform allows digital activation of international plans in various countries, without the need for physical SIM card exchange.

This can be useful for:

• professionals in international transit
• embarked teams
• employees on temporary missions
• multinational operations

In practice, the model reduces part of the operational complexity related to international connectivity.

Another important point is flexibility.

Offshore teams frequently alternate between countries, airports, ports, and operational bases. The international eSIM reduces the time needed for mobile communication activation in these movements.

Additionally, the digital model favors corporate scalability and greater administrative control over mobile lines.

Implementation: how your company can adopt corporate eSIM

The adoption of corporate eSIM tends to be gradual and complementary to the technologies already used offshore.

The process usually involves:

1. Identification of operational profiles

Evaluate:

• who really needs international mobility
• frequency of travel
• need for corporate mobile access

2. Device compatibility

Check if the devices used support:

• eSIM
• multiple profiles
• corporate management

Today, various premium Android and iPhone models already have native compatibility.

3. Definition of connectivity policy

The company can define:

• which teams will use eSIM
• mobile data limits
• international usage rules

4. Integration with existing operations

The eSIM does not completely replace critical solutions like offshore satellite, but it can act as a complementary layer of corporate mobility and connectivity.

This reduces operational costs and improves flexibility.

The future of offshore connectivity

The global trend points to increasingly connected offshore operations.

The growth of:

• industrial IoT
• remote monitoring
• corporate mobility
• operational digitalization

is expected to increase the demand for flexible communication solutions.

In this scenario, eSIM emerges as a modern alternative to simplify part of the management of international connectivity in complex environments.

Although it does not replace all traditional offshore technologies, the digital model enhances operational flexibility and reduces logistical barriers for global companies.
