How eSIM Provides Local Numbers for Travellers

eSIMs make it easy for travellers to get local phone numbers without the hassle of visiting stores or dealing with postal delays. Everything is handled digitally, saving time and effort.

Getting a Local Number with eSIM

To get a local number, you can buy a prepaid eSIM plan directly from local carriers. Many carriers offer these plans online or through their apps, so you can set things up before you even arrive. Alternatively, you can purchase a plan in person at places like airport kiosks or carrier stores. Activation is usually straightforward, often involving a QR code or a carrier app to guide you through the steps.

Before getting started, make sure your device supports eSIMs and is unlocked for international use. Depending on the country, you might also need to provide identity verification, such as showing your passport, to comply with local regulations.

If you’re looking for a simpler option, ZIM Connections offers international eSIM plans that include local phone numbers in over 200 destinations. Their prepaid voice and data plans eliminate the need to navigate various carrier websites or deal with potential language barriers. Activation is quick and easy – just scan a QR code or use their app over Wi-Fi, and you’re up and running in minutes. This convenience allows travellers to pick the plan that’s best suited to their needs.

Data-Only vs Voice and Number eSIM Plans

When choosing an eSIM plan, you’ll need to decide between a data-only plan or one that includes voice and a local number. Each option caters to different travel needs.

Data-only eSIMs are a popular choice for tourists. They’re usually more budget-friendly and allow you to use VoIP apps like WhatsApp or Skype for calls and messages, all while keeping your primary number active. These plans provide reliable 5G or 4G internet, making it easy to stay connected through messaging platforms.

Voice and number eSIM plans, on the other hand, include a local phone number for calls and SMS. These are particularly useful if you need to interact with local businesses or services that require a local number for verification. While data-only plans are often the cheaper option, having a dedicated local number can be a big advantage for business travellers or those on extended stays.

ZIM Connections offers both types of plans – local, regional, and global – so you can choose the one that fits your travel needs best. Whether you go for a data-only plan or one with voice and a local number, you’ll have the flexibility to stay connected during your trip.

Using Dual SIM Features

Once your local number is activated, you can take advantage of your phone’s dual SIM capabilities to manage both your UK number and your local eSIM. Modern smartphones with Dual SIM technology let you use an eSIM alongside your regular SIM, making it easy to stay connected on both numbers without swapping physical SIM cards.

To keep things organised, label your plans in your device settings (e.g., ‘UK SIM’ and ‘Local eSIM’). You can then set a default line for calls, texts, and mobile data based on your preferences. Features like "Allow Mobile Data Switching" let your phone automatically pick the best available connection. This setup ensures you’ll still receive important calls on your UK number while benefiting from local connectivity for data and domestic calls, helping you avoid costly roaming charges.

Step-by-Step Setup Guide

Setting up a local number with an eSIM can be a smooth process once you understand the steps. Here’s how to get your device ready and working seamlessly.

Check Device Compatibility

Before diving in, make sure your smartphone supports eSIM technology and is unlocked for international use. Most phones released since 2018 are eSIM-compatible, but this can vary depending on your location and carrier.

The easiest way to check is through your device settings:

Samsung Galaxy: Go to Settings > Connections > SIM Manager. If you see an "Add eSIM" option, your device is compatible.
Google Pixel: Navigate to Settings > Network & Internet and tap the ‘+’ next to SIMs. If you see "Download a SIM instead?", your phone supports eSIM.
Huawei: Open Settings > About Phone and select the option to display the EID. If an EID number appears, your phone is eSIM-capable.

Alternatively, dial *#06# on your phone to view your eSIM identification number.

Also, ensure your device is carrier-unlocked. Locked phones won’t accept international eSIM plans. If you’re unsure, contact your UK carrier to confirm the status. Once compatibility is confirmed, you’re ready to move on to selecting a local eSIM plan.

Purchase a Local eSIM Plan

With your device ready, it’s time to choose a local eSIM plan that suits your needs. Providers like ZIM Connections offer a range of options, including local, regional, and global plans, covering over 200 destinations worldwide. They even provide local phone numbers to keep you connected wherever you go.

When purchasing, you’ll usually need to provide basic details, and in some countries, passport information may be required to register your number.

Make sure to buy and install the eSIM profile before leaving the UK, ideally while connected to reliable Wi-Fi. This avoids potential issues with downloading the profile once abroad. Many providers, including ZIM Connections, allow you to purchase in advance and activate the plan upon arrival.

Downloading the provider’s app can also simplify the process, enabling one-click downloads and easier management of your settings.

Activate the eSIM and Local Number

Activating your eSIM is straightforward and can be done using a QR code, the provider’s app, or manual entry.

QR Code Method: Open your phone’s camera or go to your eSIM settings and scan the QR code. The profile will download and install automatically.
App-Based Activation: Download the provider’s app and follow the guided steps to activate your eSIM.
Manual Entry: Enter the SM-DP+ Address and activation code provided by your carrier in the "Add Cellular Plan" section of your eSIM settings.

It’s best to activate your eSIM while connected to stable Wi-Fi, ideally just before your flight or shortly after landing. Once activated, ensure mobile data (and roaming, if needed) is enabled in your settings. Some providers even offer automatic activation when you reach your destination. After activation, your eSIM is ready for use, allowing you to switch easily between your UK number and your local number.

Switching Between UK and Local Numbers

Managing both your UK number and local eSIM is simple, thanks to dual SIM technology. Start by labelling each plan in your settings – e.g., "UK SIM" and "Local eSIM" – to avoid confusion.

For iOS users:

Go to Settings > Cellular (or Mobile Data).
Under SIMs or Cellular Plans, review your installed eSIMs.
Select the active eSIM and disable the other if needed.
Use Cellular Data to choose which eSIM handles your data connection.

By default, your iPhone uses the last number you called a contact with, but you can specify a different number if needed.

For Android users:

Navigate to Settings > Connections (or Network & Internet) > SIM Manager (or Mobile Network).
Review your eSIM list and toggle them on or off as required.
Choose your preferred SIM for mobile data, calls, and texts in the settings.

Switching between numbers is also easy. For example, on an iPhone, tap the Info button next to a contact in your favourites to select a different number. When using the keypad, enter the number, tap the displayed phone number at the top, and choose the line you want. In Messages, tap the current number at the top of a conversation to switch.

Keep in mind that only one number can use mobile data at a time, but you can adjust this setting as needed. Thanks to Dual SIM Dual Standby technology, both numbers stay active for incoming calls and messages, so you won’t miss anything important.

Benefits for UK Travellers

eSIM technology isn’t just about staying connected; it offers a host of benefits that can make travelling abroad easier and more budget-friendly for UK travellers. By using a local number through eSIM, you can enjoy better rates, improved connectivity, and greater convenience during your trip.

Avoid Expensive Roaming Charges

One of the biggest perks of using a local eSIM is the potential to save money. Traditional roaming fees charged by many UK operators can quickly add up, often resulting in unexpected costs. However, with a local eSIM, you connect directly to local networks, avoiding those hefty charges. In fact, eSIM plans give travellers access to affordable data in over 190 countries, allowing you to pay for data upfront and stay in control of your budget.

For even more cost management, monitoring your data usage or choosing an unlimited data plan (where available) can prevent surprises. This makes it easier to plan your travel expenses without worrying about hidden fees.

Easy Communication with Local Contacts

Having a local number can significantly improve how you interact with businesses and individuals abroad. For instance, studies show that 85% of people ignore calls from unfamiliar international numbers. With a local number, you can easily contact restaurants, tour operators, or service providers, signalling trust and legitimacy.

For business travellers, this is particularly useful. A local number not only enhances communication but also demonstrates professionalism, showing that you’re serious about maintaining reliable contact no matter where you are. It helps create a stronger presence in the area you’re visiting.

Privacy and Convenience

eSIM technology also brings a new level of privacy and convenience. Unlike traditional SIM cards, an eSIM is embedded in your device, meaning it can’t be removed, lost, or tampered with. This adds an extra layer of security while you’re travelling.

Using a temporary local number can also protect your personal information, reducing the risk of identity fraud. Once your trip is over, you can deactivate the eSIM, ensuring no lingering concerns about privacy.

Additionally, the dual SIM functionality allows you to keep your UK number active for essential tasks like account logins or verification codes, while using the local number for everyday communication.

"eSIM is exactly the same as the physical SIM card, which stores identification data on the chip… you as user have full control (install, delete, activate, deactivate, pause…)" – Stefan Durina, Circular Founder at Beneko Mobile

Practical Considerations and Limitations

While eSIM technology brings plenty of perks for UK travellers, it’s not without its challenges. Knowing these potential issues in advance can save you from unpleasant surprises. Below, we break down some key limitations to help you plan your travels more smoothly.

Limitations of Local Number eSIM Plans

One major drawback of many eSIM plans is that they are often data-only, meaning they don’t come with a local phone number. If having a local number is essential – whether for making calls or sending texts – you’ll need to specifically search for eSIM plans that include voice and SMS services.

In some countries, regulations require identity verification, such as providing passport details or proof of address, before issuing a local number. This can create delays, especially for short-term visitors.

The availability of local numbers also depends heavily on where you’re travelling. Popular tourist destinations usually offer a range of eSIM services, including local numbers, but in remote or less developed areas, options might be scarce. In some cases, regulatory restrictions may even prevent foreign travellers from accessing local numbers altogether.

Another important point: eSIM profiles aren’t as easily transferable between devices as physical SIM cards. If your phone gets damaged or lost during your trip, moving your local number to a replacement device can be a slow and frustrating process [12].

Device and Plan Compatibility

Not all devices are eSIM-ready, and this could throw a wrench in your travel plans. Many budget smartphones don’t support eSIM technology [12], and your phone must also be unlocked to work with international carriers. Before you leave, check your device’s compatibility on the manufacturer’s website or through your eSIM provider’s compatibility guide.

Some phones tied to specific mobile operators may only work with data plans from that network, limiting your flexibility when travelling abroad.

The activation process can also vary. Some eSIMs activate automatically after installation, while others require manual steps like scanning a QR code. Additionally, the validity period of an eSIM plan isn’t always straightforward – some start as soon as you install the profile, while others only begin once you connect to a supported network.

Coverage is another factor to consider. An eSIM might perform well in urban centres but struggle in rural or remote areas. It’s a good idea to confirm that your chosen provider offers strong coverage in the specific regions you’ll be visiting, not just the country as a whole.

Special Considerations for Local Number Use

Switching to a local number can lead to unexpected complications beyond the technical aspects. For instance, many banking apps rely on your original UK number for two-factor authentication. Changing to a local number could lock you out of these essential services when you need them most.

Social media platforms, email accounts, and other apps that use SMS verification can also cause headaches. Services like iMessage and FaceTime may require manual reconfiguration to work properly with your new number. Without these adjustments, you might find your messages and calls misdirected or not working at all.

"It has issues, it’s a ‘work-in-progress’, and frustrating to deal with." – Apple Genius Bar Tech

This candid remark from an Apple technician underscores the ongoing struggles with eSIM technology, particularly around activation and troubleshooting.

Privacy concerns are another aspect to keep in mind. Unlike physical SIM cards, eSIMs can make it easier for network providers to track your location [12], which might be unsettling for privacy-conscious travellers.

Lastly, be mindful of your UK SIM settings. Leaving roaming enabled can lead to hefty charges, as some UK networks charge £6 to £8 per day for data roaming. Make sure to deactivate or properly manage your UK SIM to avoid unexpected costs.

Conclusion

eSIMs with local numbers offer UK travellers a smart way to save money and simplify connectivity. With 56% of travellers open to switching to avoid roaming charges and potential savings of up to 90% compared to traditional roaming costs, the benefits are clear. You can set up your eSIM before your trip and enjoy local rates right away, without the hassle of searching for SIM cards upon arrival. For context, with an average connectivity budget of £33 per traveller while abroad, these savings can make a big difference.

The convenience factor is another major draw. eSIMs eliminate the need to juggle physical SIM cards, reduce the risk of losing them, and let you keep your UK number while also using a local one. This dual functionality is especially useful for things like banking authentication or making local calls. As Surash Patel, Chief Revenue Officer of Proximus Global, explains:

"eSIMs are a game-changing opportunity for brands across travel, retail, and beyond. Consumers are actively looking for cost-effective connectivity, and non-traditional providers with strong customer bases are in a prime position to meet this demand. With the right approach, businesses can easily unlock new revenue streams and enhance customer loyalty by integrating eSIM into their offerings."
Surash Patel, Chief Revenue Officer, Proximus Global

With eSIMs, you can stay connected to your UK network while also benefiting from local rates, all without overspending. This is particularly useful for business travellers or those exploring multiple countries, as regional and global eSIM plans can cover entire trips with just one activation. By 2030, 76% of smartphone connections are projected to use eSIM technology, contributing to less plastic waste and improved security.

Key Takeaways

Here’s a quick recap of the main benefits of eSIMs: they offer cost savings, convenience, and security, all while keeping you connected to both home and local networks. They address common travel challenges by allowing advance activation, providing access to local rates, and eliminating the need to manage physical SIM cards. These features make eSIMs an excellent solution for hassle-free international connectivity.

Final Tips for UK Travellers

Before you travel, check if your device supports eSIM and look into your destination’s rules. Some countries may require identity verification or have restrictions on foreign travellers using local numbers.

Choose the right plan based on your needs. If you primarily rely on messaging apps, a data-only plan might work perfectly. However, if you need SMS for banking or local calls, opt for a plan that includes voice and SMS services.

Install your eSIM before you leave, but only activate it upon arrival to avoid any connectivity issues. Don’t forget to disable roaming on your UK SIM to prevent unexpected charges.

For a reliable and flexible solution, ZIM Connections offers eSIM plans for over 200 destinations worldwide. Whether you’re heading to one country or travelling across several, their platform ensures you stay connected without the usual international travel headaches. It’s the modern way to stay online, no matter where your journey takes you.

FAQs

How does an eSIM with a local number help save on roaming charges while travelling?

Using an eSIM with a local number lets you tap into local networks directly, saving you from the hefty roaming charges that often come with your primary SIM provider. Instead of sticking to international roaming, you can activate a local data or voice plan, which tends to be far more budget-friendly.

This is particularly handy for travellers, offering uninterrupted connectivity without the surprise of extra fees. With an eSIM, you benefit from local rates for calls, texts, and data – perfect for staying connected while exploring new destinations.

What’s the difference between data-only and voice-enabled eSIM plans, and how do I choose the best one for my trip?

Data-only eSIM plans are designed for internet access without a phone number. They’re a great choice if your main focus is browsing, using apps, or streaming while on the move. Plus, they often come at a lower cost compared to other options.

Voice-enabled eSIM plans, however, include a local or international phone number, enabling you to make calls and send texts. These are ideal if you need traditional communication methods during your travels.

Go for a data-only plan if you primarily use internet-based services like WhatsApp or Zoom to stay connected. If making regular phone calls or sending SMS messages is essential, a voice-enabled plan is the better option.

How can I check if my device supports eSIM before travelling abroad?

To check if your device supports eSIM technology, start with your device settings. For iPhones, head to Settings > General > About, and look for the EID number. On Android devices, you can usually find this by going to Settings > About Phone, or by dialling *#06# to view the EID or eSIM details.

It’s also important to confirm that your device is unlocked and eSIM-ready. If you’re unsure, reach out to your device’s manufacturer or your service provider for confirmation. Verifying compatibility ahead of time can save you hassle and ensure you stay connected without interruptions during your travels.
