eSIM for business is gaining popularity across industries, especially among mobile teams, replacing traditional SIM cards and simplifying remote operations. Whether you manage a small startup or a corporation with multiple offices worldwide, adopting a virtual SIM can transform your communication strategy. As companies expand overseas, providers like Ohayu help streamline communications, monitor data usage, and reduce spending.
This article explains how eSIM for business works, its main advantages in savings, security, and network quality, and how to choose the most reliable provider for 2025.
What is eSIM for Business?
An eSIM for business is a digital (embedded) SIM profile built into a device – smartphones, tablets, and even wearable tech such as smartwatches. Unlike a traditional SIM, the digital version can connect to available partner networks automatically, depending on how the provider configures the profile. It can be easily installed or removed, and allows several profiles to be stored on the same device, since it is not limited by the number of SIM slots.
Most flagship and mid-range phones produced after 2020 are eSIM-compatible, an exception is some basic Android models. You can check your device compatibility by dialling *#06# (this is not a call, just a free request to your device system) to display your phone information – if there is an EID number listed, your phone likely supports eSIM. Another way is to check your device settings: for iPhone, navigate to Mobile Data, and for Android, review the Network & Internet menu.
Under GSMA Remote SIM Provisioning (RSP) standards, it can switch between local operators based on your location, automatically. This means the user can land in any supported country, activate the data plan, and begin using the data right away – all while keeping the primary phone number for calls or apps like WhatsApp or Viber. With no physical card to insert or change, it brings convenience and flexibility to corporate use.
As a result, an eSIM for Business has become the preferred choice for companies managing employees across multiple regions.
New Rules of Business Travel
Switching to a corporate eSIM is one of the most significant upgrades in enterprise travel connectivity since 4G came along. The embedded SIM is supported by more than 400 mobile phone operators worldwide. For solo travellers like me, it’s both a practical convenience and a strategic upgrade that affects key areas: resource management, security, and operational efficiency. This is part of the big picture of how technology has a prominent position within business mobility.
If your company is still paying for roaming or leaving you to hunt for a local SIM every time you land, it’s a waste of both money and productivity. Wherever I land, my phone connects automatically, and I can get straight to work. For modern teams, it represents a new standard of connectivity and cost efficiency.
Why eSIM for Business is a Must
Key benefits of using data packages include price, coverage, and security. I have experienced these three benefits myself, so a digital SIM is a definite must-have for my work assignments abroad.
1. Real Cost Savings: Skip the Roaming Bill
Corporate mobile plans usually include roaming packages, which may become expensive once the data allowance is exceeded. So-called ‘roaming shock’ can significantly affect the budget of a company with frequent field trips.
With a virtual SIM, you can get a prepaid data bundle for the country you are visiting. These plans are notably cheaper than roaming rates because many eSIM vendors buy data via roaming agreements with local carriers. As a result, companies can forecast and control travel expenses more effectively, than with traditional roaming plans.
2. Consistent Global Connectivity
Everything moves fast in the work environment, and even a short delay in getting online can be a loss of valuable time. With an eSIM for business, accessing mobile networks becomes effortless. The digital SIM is built into your device, so there’s no need to buy or swap a local card. After you land, turn off the Flight Mode and activate your profile to get connected to the best signal.
For business, that means uninterrupted calls and meetings across borders. It keeps the projects moving, even when you’re on another continent. That’s exactly why organisations that operate abroad are increasingly integrating eSIM for business into their standard employee toolkits.
This setup can be described in 3 steps:
- Install a data plan before your trip.
- Turn off Flight mode when you land in your destination and activate your profile.
- Your phone is connected to the best local partner signal.
Right after that, you can send emails, jump on a Zoom call, or brief the team before leaving the airport. It’s a great example of technology making travel awesome.
Can I Use eSIM for WhatsApp Business?
This is one of the biggest advantages of this technology. When using an eSIM for data purposes, your primary phone number – the one linked to your WhatsApp account – remains active.

You can use WhatsApp, Viber, or any other app easily and securely, at lower costs and without changing your number. This flexibility makes eSIM for business a smart tool for teams relying heavily on communication platforms.
3. Enterprise-grade Security
When we talk about work trips, security is crucial. A safe connection is critical when handling confidential company data, and a public Wi-Fi in places like airport terminals or cafes rarely meets this requirement. This is where an eSIM makes a difference.
- No physical swap risk: A physical SIM card can be lost or stolen, while an embedded chip is built into the device, making it harder to access or tamper with.
- Encryption: data stored on the eSIM is cryptographically protected, offering a high level of security.
- Remote control: IT departments can activate, deactivate, or replace a data plan remotely if a device is lost.
In short, eSIM for business provides better protection than traditional SIM cards.
What’s the most secure eSIM for business use in 2025?
Enterprise eSIMs have high-end security features, which most consumer plans lack. All leading business digital SIMs comply with the GSMA RSP standard and support remote provisioning, enabling centralised control and over-the-air profile updates.
For example, Verizon and T-Mobile’s solutions can work with secure authentication protocols, and management dashboards that IT departments can use to monitor usage and enforce security policies.
Another example is Ohayu, a global eSIM provider with a 4.5+ TrustPilot rating. Its platform offers clear visibility of your plan usage and prioritizes user data protection. The company operates in compliance with GDPR requirements and processes payments through 3D Secure (3DS) checkout systems by trusted payment processors.
What’s the Best UK eSIM for Business?
This question is the one I am most often asked by colleagues. You can either choose a traditional operator or a specialised international vendor.
Traditional mobile operators in the UK and abroad, such as Vodafone, EE, O2, T-Mobile, Verizon, and Orange, offer digital SIM options within their own networks and roaming packages. However, these services are not designed for multi-network capability and are primarily focused on maintaining their own infrastructure.
Location-centric providers like Ohayu fill this gap. They do not own towers but cooperate with local carriers, including those mentioned earlier, seamlessly connecting users to the strongest available signal without adding roaming fees. For many UK-based firms, eSIM for business platforms combine cost savings with the best coverage worldwide.
The budget difference is even more noticeable for teams. I have worked with companies moving away from traditional roaming-based contracts to international mobile data solutions and reducing their communication expenses by 50-70%. That can amount to over £10,000 in annual savings for a team of remote workers.
Price Comparison of Corporate eSIM Plans
The end decision often boils down to a simple cost-of-use consideration. Here are examples of current data plans for a 30-day trip.
| Provider | Business eSIM Features | Price (per month, global) | Notes |
| Ohayu | Connects you to the best local signal automatically; flexible data packages; coverage in 190+ countries with country plans, and 110+ countries with a Global subscription. | From £5.90 (yearly, 24GB) | Automatic connection to local networks, e.g. Vodafone, O2, EE |
| Vodafone | Roaming in 51 European destinations; 6x unlimited data boosters | From £18.33 ex. VAT (1GB, Unlimited mins/SMS) | Good for EU-based firms, but less competitive outside Europe |
| O2 | 123 destinations worldwide | From £15.24 (40GB, Unlimited UK mins/texts) | Doubles in price after 12 months |
| EE | Includes 40 European destinations and 7 international locations (requires the addition of Roam Abroad Pass). | From £20.00 ex. VAT (10GB, Unlimited calls/SMS) | Fast speeds, but pricing varies widely |
| Verizon | Excellent US coverage; available in 210+ destinations | From £74.30 (Unlimited data/texts, 250 mins) | Strong in the US, weaker pricing internationally |
| T-Mobile | 215+ countries and destinations; Unlimited full-flight Wi-Fi sessions on U.S.-based airlines | From £30.00 (5GB, Unlimited talk, text, and data in Canada and Mexico) | Popular for multinational teams |
| Orange | Footprint in over 200 destinations | From £32.00 (20GB, 15mn and 50 SMS to the world) | Good option for France/Africa locations |
Note: These costs fluctuated considerably depending on the existing contract in the case of a traditional MNO like Vodafone or Verizon. The prices are tied to legacy agreements for roaming. The new-generation third-party providers (i.e., Ohayu) work on a more flexible, localised model and connect to MNOs all over the UK and the world with utmost speed. Prices verified in Q4 2025 via official websites; subject to change. Overall, these comparisons highlight why eSIM for Business has rapidly become a cornerstone of modern resource management.
Why I Chose Ohayu for My 2025 Business Strategy
Having tested several options over the past two years, I keep returning to the Ohayu Global eSIM for my international work setup. The primary reasoning is simple: to eliminate the complex choice of local networks and have the most reliable performance.

Traditional mobile plans require you either to accept roaming partnerships with your carrier or to manage multiple SIM profiles in various regions. However, Ohayu’s automatic network selection frees you from the need for both. There are no hidden payments, confusing tiers, or fair-use policies that are more opaque than you could imagine. I can pick a plan that suits my data consumption habits and manage it via the mobile app.
In other words, switching to cross-border connectivity solutions was an excellent decision. If your company is still paying high roaming fees, now is the time to check whether this technology can offer your team a similar cost-saving. For 2025 and beyond, adopting eSIM for business is not just about convenience – it’s about giving your company the flexibility to operate efficiently anywhere.
