    How does the Roamify eSIM work?

    1

    Pick the eSIM plan

    From unlimited data to fixed data and even plans with calls and hotspots, we have the right plan for you.

    2

    Pay for your order

    Chose the plan that suits you best and buy your eSIM card from our website or app. You will receive an email with your QR code.

    3

    Scan the QR code

    It's easy. Just scan the QR code we send you and turn on data roaming from your settings. Now you can enjoy it on your trip.

    Frequently Asked Questions about the Guernsey eSIM

    Everything you need to know about the Guernsey eSIM.

    01

    When does my data plan start?

    +

    Your plan starts the moment you activate your eSIM by scanning the QR code on your smartphone.

    02

    Can I make phone calls and send messages with the eSIM?

    +

    Unfortunately, the Guernsey plan only allows you to use mobile data. It does not include a phone number for mobile calls or messages. You can still make calls using apps like WhatsApp.

    03

    When will I receive my eSIM?

    +

    Once you purchase an eSIM, you will receive it immediately to your email address. You then just need to scan the QR code to activate the SIM. Note that no refunds can be made once you purchase your eSIM. See our refund policy for more information.

    04

    Can I keep my WhatsApp number?

    +

    You don't need to do anything to keep your WhatsApp number. You'll automatically keep your number, contacts and conversations.

    05

    What is the network speed of the eSIM?

    +

    The Roamify eSIM offers maximum speed coverage. But bear in mind that in some areas of limited coverage there may be a lower speed connection.

    06

    Do I have to activate data roaming on my device?

    +

    Yes. To ensure that your eSIM gets the best coverage, you must turn on data roaming on your mobile settings. This will not incur any additional charges, as long as you have already set up the eSIM.

    07

    Will my eSIM have a local IP address in Guernsey?

    +

    Not always. This plan connects through a roaming partner, so websites and apps may see an IP address registered in another country rather than in Guernsey. This is normal for travel eSIMs and does not change your data allowance, speed or coverage. If a service requires a local IP address, such as some banking apps or regional streaming catalogues, connect through a local network or use a VPN set to Guernsey.

    08

    What do I do if I delete or lose my eSIM's QR code?

    +

    If you cannot find the code, please contact our 24/7 customer support team at support@getroamify.com or our online chat function. We will resend the code to your email.

    09

    What happens if I use up my data or ny days of validity?

    +

    If you use all your data or run out of days, your eSIM card will no longer work and you will lose internet connection.

    10

    What eSIM data plan should I choose for Guernsey?

    +

    You can choose variable plans as shown above. You can contact us at any time if you're not sure which plan is best for you.

    11

    Will the connection speed be reduced?

    +

    This eSIM includes unlimited data for the contracted time. However, please note that the operator may reserve the right to apply a Fair Usage Policy, as it applies to all other network users. In particular, if the operator estimates the usage of more than 90GB of data in a month, it may temporarily reduce the speed to between 256-1024KB to avoid affecting other users. This limitation is intended to prevent network saturation and will be removed within 24 hours. If you think the local operator has limited your speed, please get in touch with us by chat, and we will check if there is any incidence and how to restore your rate to the maximum speed allowed by the network.

    12

    Can I renew or extend the data on my eSIM?

    +

    Yes, you can do so by logging into your customer panel on the Roamify website. You will find the data plans you can purchase there. Once you've made your purchase, it will be activated immediately on the eSIM you have linked.

    13

    Can I share data with other devices?

    +

    Yes, you can share data with other devices. You can do this by activating the hotspot on your device.

    14

    How do I set up the eSIM on my device?

    +

    Once you make your purchase, we will send you an email with precise instructions to install your eSIM in two ways; by scanning the QR code or by copying and pasting the manual installation codes. To install with the first option, it is essential that the QR code is printed or on another device. Otherwise, you can follow the manual installation instructions for your Roamify eSIM. If your device is iOS, you must enter Settings → Cellular → Add eSIM on your device and scan the QR code or paste the manual installation codes sent to your email. You must then follow the on-screen instructions to select your new eSIM for mobile data and calls. If your device is Android, follow the instructions we will email you to install your Roamify eSIM. Remember that your Roamify data plan should only be activated when you arrive at your destination. Once there, make sure to select your Roamify eSIM as your preferred option to make calls, then activate data roaming and also the Roamify calling plan. At Roamify, we want to make setting up your eSIM as easy as possible. For this reason, all our eSIM products come with complete instructions for easy setup. If you have any questions or need help, don't hesitate to contact our customer support team. We will be there for you 24/7.

    15

    When should I set up my eSIM?

    +

    Set up your eSIM before your departure. Once you reach your destination, just activate the data plan and turn on data roaming. We recommend you print the QR code and take it with you on your vacation just in case. Remember that you need internet access to activate the eSIM. Set up is quick and you will be able to enjoy your data plan right away.

    16

    How can I check how much data and minutes do I have left?

We're always happy to assist you with any questions or concerns you may have.

    17

    How many times can I use my eSIM card?

    18

    How can I delete the Roamify eSIM once I've used my data?

    +

    You don't need to delete the eSIM. But if you want to, please see how to delete eSIM on iOS and Android.

    19

    Can I use my (physical) SIM card and Roamify eSIM at the same time?

    +

    Sure! You can keep your physical SIM card with your Roamify eSIM simultaneously on your device. Just make sure you choose your eSIM as your default voice line and preferred option for mobile data in your device settings. Please note that if you leave your physical SIM card activated, you might get extra roaming fees from your network provider.

    20

    How do I get a refund?

    +

    The eSIM is a digital product. Roamify cannot check if you have used the data plan associated with the eSIM card. Therefore, once your eSIM is delivered, we cannot offer a refund. Please see our eSIM Refund Policy for more information.

    21

    Which eSIM carrier will I connect to in Guernsey

    Connectivity on the Cliff Paths of Guernsey

    Guernsey offers a unique blend of picturesque trails and quaint towns. As you meander along the cliff paths above St Peter Port, the island's capital, you'll enjoy breathtaking views of the English Channel. Visits often include a boat trip to the tranquil island of Herm, or a stroll through St Sampson and Castel. Staying connected here means balancing between nature's serenity and modern convenience.

    Mobile connectivity in Guernsey is remarkably good in urban areas like St Peter Port, where most travellers find themselves starting their journey. However, as you venture onto the cliff paths or take the boat to Herm, service can become spotty. The high cliffs and remote parts of the island are scenic but can sometimes challenge a stable connection.

    Before you fly

    To make the most of your trip, ensure your eSIM is set up before you land on the island. Download maps and any important documents you might need while you're still in a well-covered area. Upon arrival, you can expect reliable service in populous areas, which will help you stay connected as you explore Guernsey's charming towns and stunning coastlines.

    Using an eSIM in Guernsey

    Answers to the questions travellers actually ask about staying connected in Guernsey.

    20 questions

    What steps should I take to activate my travel eSIM upon landing at Guernsey Airport (GCI)?

    +

    Upon landing at Guernsey Airport, ensure your device is connected to the airport's Wi-Fi. Access your eSIM settings and follow the provider's activation instructions. Ensure roaming is enabled in your device settings. Restart your device if necessary, and check for a signal to confirm activation.

    Will my eSIM have coverage on the ferry from Guernsey to Herm?

    +

    Your eSIM will generally have coverage near Guernsey, especially when departing from St Peter Port. As you move toward Herm, the signal may weaken due to the distance from cell towers on the main island. To ensure you have essential information, download maps and documents before departure. Despite patchy coverage, you'll likely be able to stay connected close to the coast, but unpredictable areas make preparation essential.

    Is there reliable eSIM coverage in the scenic cliff paths above St Peter Port?

    +

    Coverage on the cliff paths above St Peter Port is typically strong, as these areas are near major urban centers. However, the rugged terrain and elevation can lead to occasional weak spots. To avoid issues, download offline maps in advance and enjoy the trails without worrying about constant connectivity. The close proximity to St Peter Port's network infrastructure generally assures a good connection, especially at higher elevations.

    Can I use my eSIM to access local transportation apps in Guernsey?

    +

    Yes, your eSIM enables access to local transportation apps in Guernsey. Guernsey's coverage in urban areas like St Peter Port and St Sampson helps maintain consistent internet. To ensure seamless access, download transportation apps and maps before leaving home. This helps you navigate schedules and routes even if you encounter weaker signals during your travels. Moreover, pre-downloading apps minimizes potential connectivity interruptions.

    How does eSIM coverage perform in the rural areas like Castel?

    +

    In Castel and other rural parts of Guernsey, eSIM coverage can vary due to sparse cell towers and natural obstructions. While serviced areas generally receive signals, deeper rural spots might experience inconsistencies. If your itinerary includes significant time in these regions, plan for offline resources and communication alternatives. This ensures your plans aren't hindered by connectivity issues, allowing for a more seamless travel experience.

    +See all 20 questions

    Can I use WhatsApp with an eSIM while exploring the Channel Islands from Guernsey?

    +

    WhatsApp should work effectively with an eSIM while exploring the Channel Islands. The service operates over data, which is available across most islands, including Guernsey and Jersey. Roaming settings may need adjustment when moving between islands to maintain coverage. Prepare by confirming your eSIM settings for data roaming and ensuring you're aware of each island's specific network capabilities. This allows for uninterrupted communication during your travels.

    What should I do if I run out of data on my eSIM during my visit to St Sampson?

    +

    If you exhaust your eSIM data in St Sampson, check your provider's app or website for top-up options. The area offers several Wi-Fi hotspots in cafes and public spaces, providing interim connectivity. Alternatively, visit local carriers' stores for additional data plans. Preparing in advance by identifying potential Wi-Fi networks ensures you remain connected and informed without worrying about running out of data unexpectedly.

    Is dual SIM functionality supported when using an eSIM in Guernsey for international calls?

    +

    Dual SIM functionality is generally supported in Guernsey, allowing eSIMs for data while a physical SIM manages international calls. Ensure your phone model supports dual SIM usage, and configure it accordingly before your trip. This lets you benefit from both local eSIM data and international calling via your physical SIM, providing flexibility in maintaining connections with minimal setting adjustments when abroad.

    How is the internet speed with an eSIM when staying in hotels in St Peter Port?

    +

    Internet speed with an eSIM across hotels in St Peter Port is typically strong, as the area benefits from comprehensive network service. Speeds may fluctuate due to hotel-specific infrastructure or network congestion, especially during peak times. To optimize, try off-peak internet usage, and inquire with hotels about any available high-speed options. This ensures more reliable connectivity throughout your stay, facilitating seamless communication and access.

    What should I do if my eSIM isn't connecting after arriving from Herm Island?

    +

    After arriving from Herm Island, first confirm your device's network settings are set to automatic selection. Restart the device, as this can often resolve connectivity issues. If the problem persists, check for network updates or contact your eSIM provider's support for assistance. Additionally, ensure roaming is enabled for seamless transition across networks, especially when traveling between islands or further from main service areas.

    Will my eSIM work in both St Peter Port and St Sampson without changing settings?

    +

    Your eSIM should function seamlessly in both St Peter Port and St Sampson without needing setting adjustments. Both locations fall within the primary coverage area of Guernsey's network infrastructure. This continuity simplifies connectivity, ensuring reliable access as you travel between these key commercial and residential areas. Always verify your phone's network settings align with automatic network selection to avoid potential disruptions.

    How do I ensure my eSIM works for mobile hotspot use while exploring the Guernsey countryside?

    +

    To use an eSIM as a mobile hotspot in Guernsey's countryside, confirm that your data plan supports tethering. Verify these settings in your phone's configurations and check signal strength before relying on it for critical connectivity tasks. Forested and less-developed areas might challenge consistent hotspot functionality, so plan ahead by downloading necessary information. Additionally, staying in open spaces often enhances reception.

    Are there any specific areas in Guernsey where eSIM connectivity is known to be weak?

    +

    Certain parts of Guernsey, particularly rural and remote areas like parts of Castel, experience weaker eSIM signals due to limited cell towers and natural barriers. While urban centers such as St Peter Port maintain strong coverage, planning visits to less populated areas might require downloading critical information beforehand. This preemptive approach ensures access to necessary resources despite potential connectivity challenges you may encounter.

    Will my eSIM automatically connect to the best available network while walking the cliff paths?

    +

    Most eSIMs are designed to auto-connect to the strongest network available. Walking the cliff paths above St Peter Port generally provides good connectivity, but signal strength may vary due to the undulating terrain. For assured access to information, download maps or guides in advance. This ensures that even when temporary connectivity drops occur, you remain informed without relying solely on real-time data.

    What happens to my eSIM connection if I take a boat trip from St Peter Port to Sark?

    +

    During a boat trip from St Peter Port to Sark, expect intermittent eSIM connectivity, particularly mid-journey, due to distance from main cell towers. To counteract potential disruptions in connectivity, download necessary maps, guides, or communications before departure. Utilize offline modes or saved details to navigate effectively during the transitional crossing, ensuring uninterrupted access to essential information and guidance throughout the trip.

    Can I manage my eSIM settings using local Wi-Fi in St Peter Port cafes?

    +

    Yes, managing eSIM settings via local Wi-Fi in St Peter Port's cafes is possible and practical. With reliable internet access, you can update plans, troubleshoot issues, or download necessary resources without relying on mobile data. Identifying Wi-Fi hotspots during early stages of your visit facilitates seamless connectivity management, ensuring you're well-prepared for any adjustments or configurations needed throughout your stay.

    How do I troubleshoot slow eSIM data speeds in busy areas of St Peter Port?

    +

    To address slow eSIM data speeds in St Peter Port's busy areas, first restart your device. Experiment with toggling between 3G and 4G network modes. If issues persist, manually select alternative networks in settings, as congestion can affect performance. By taking these steps, you mitigate potential delays, ensuring more consistent access to data and applications during peak times in crowded locations.

    Will my eSIM support emergency calls while hiking in Guernsey's rural areas?

    +

    eSIMs generally support emergency calls across Guernsey, yet signal strength in rural hiking areas may vary. To ensure safety, bring a backup device with emergency contacts stored offline. Pre-hiking, confirm local emergency numbers and consider informing someone of your route. Signal reliability improves closer to populated areas, but advance preparation ensures assistance is accessible should unforeseen circumstances or connectivity issues arise.

    How can I optimize data usage with my eSIM while touring Guernsey's historic sites?

    +

    Optimize eSIM data usage by pre-caching maps and guides for Guernsey's historic sites. Utilize local Wi-Fi connections at attractions, adjusting app settings to limit background data usage. This strategic approach minimizes consumption, extending available data for essential services. Prioritizing offline resources and consciously managing settings ensures you efficiently balance data constraints and maintain access throughout your exploration of the island's cultural landmarks.

    Is it possible to switch between Guernsey networks manually if my eSIM signal is weak?

    +

    Yes, you can manually switch between networks if your eSIM signal weakens. Access your phone's network settings and initiate a manual search to select a stronger alternative. This flexibility is essential in areas where automatic selection struggles, particularly in rural or less serviced regions. Regularly checking and adjusting settings facilitates continued connectivity, allowing seamless transitions and stable reception during your travels.
