    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 Guam eSIM

    Everything you need to know about the Guam 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 Guam 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 Guam?

    +

    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 Guam. 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 Guam.

    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 Guam?

    +

    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?

    +

    To check your remaining data balance, simply log in to our web app using the access details that we sent you via email when you made your purchase. You can also check your data balance in your device's data settings. To check your remaining minutes balance for making or receiving calls, please contact our support team. 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 Guam

    +

    The Guam eSIM uses one of the best eSIM providers in the country.

    Signal Strength Along Guam's Tumon Bay and Beyond

    Guam, locally known as Guåhan, offers a unique blend of vibrant city life and serene natural beauty. Travellers often find themselves exploring the bustling streets of Hagåtña, relaxing on the beaches of Tumon, or venturing into the lively markets of Dededo. Many journey to Apra Harbor to dive into historic wrecks or take in the breathtaking views from the cliffs overlooking Tumon Bay. As you traverse this island, staying connected can enhance your experience and keep you in touch with your surroundings.

    Connectivity in Guam tends to be strong in urban areas like Hagåtña and the tourist hotspot of Tumon. However, as you move toward more remote locations or venture into the rugged interior, signals can become less reliable. Areas with denser vegetation or higher elevation, such as the northern parts of the island, may not offer the same level of connectivity as the city centres do. Being aware of this helps in planning your communication needs effectively.

    Before you fly

    Before arriving in Guam, it's wise to set up your eSIM so you can have seamless connectivity as soon as you land. Downloading maps and guides in advance is also a good idea, especially if you plan to explore areas where coverage might be spotty. Expect robust service in the cities, but prepare for possible interruptions when you step into the island's more secluded spots.

    Using an eSIM in Guam

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

    20 questions

    Is there mobile network coverage in Apra Harbor for eSIM users?

    +

    Yes, Apra Harbor is generally covered by Guam's mobile networks because it's a popular spot for diving and marine activity. Most local carriers provide sufficient coverage in this area, but service quality might vary. It's recommended to check your eSIM provider's coverage map to ensure consistent service before you set out. Getting a local map with offline features can also help in case of spotty connections.

    How do I activate my eSIM upon arrival at Antonio B. Won Pat International Airport?

    +

    Activating your eSIM at Antonio B. Won Pat International Airport is straightforward. Once your plane lands and you're cleared to use your phone, go to your device settings, select 'Cellular' or 'Mobile Data', and activate your eSIM profile. Ensure your device is compatible with eSIM technology.

    Can I use my eSIM for data while hiking the cliffs above Tumon Bay?

    +

    You can generally use your eSIM for data while hiking the cliffs above Tumon Bay. This area often has good network coverage due to its proximity to Tumon, a major tourist area. Still, coverage can vary based on your provider, so verify your eSIM’s specific coverage before you go. Download offline maps or resources as a backup if connectivity becomes an issue during your hike.

    Will my eSIM work for internet access in the village of Dededo?

    +

    Your eSIM is likely to work for internet access in Dededo, which is one of Guam's more populated and developed villages. Local carriers have a robust presence here, enhancing connectivity. When visiting Dededo, affirm that your eSIM matches the local network frequencies and verify this with your eSIM provider. Download necessary information in advance to avoid disruptions while you're exploring the area.

    Is there reliable eSIM coverage on public transport routes in Hagåtña?

    +

    Yes, eSIM coverage is generally reliable along public transport routes in Hagåtña, Guam’s capital. The city's infrastructure supports strong network services. However, signal strength can fluctuate based on the exact route or bus schedule. Always check in advance by consulting your eSIM provider's coverage details. Also, carrying a portable Wi-Fi hotspot may offer additional connectivity insurance during your trip.

    +See all 20 questions

    Can I tether my eSIM data connection to other devices while on the beaches of Tumon Bay?

    +

    You can indeed tether your eSIM data connection to other devices while enjoying the beaches of Tumon Bay. The area benefits from robust network infrastructure due to its status as a tourist hub. Before doing so, ensure your eSIM plan supports tethering to avoid unexpected charges. If unsure, consult your provider and maybe have an offline backup for critical data needs.

    Will my eSIM maintain connection while diving near shipwrecks in Apra Harbor?

    +

    Your eSIM will likely not maintain a connection underwater near the shipwrecks in Apra Harbor. Mobile networks typically don’t extend below the water surface, so you can anticipate losing connectivity when diving. Before you dive, it's smart to download any necessary maps or guides for offline use to aid in navigation and exploration without the need for a data connection.

    If my eSIM does not connect in Tumon, what troubleshooting steps should I take?

    +

    If your eSIM isn't connecting in Tumon, start by confirming your device is not in airplane mode. Then, restart your phone and ensure your eSIM profile is active in the settings. Check for any network selections specific to your eSIM provider. If these steps don't resolve the issue, contacting your provider for support is advisable. Having a secondary plan like local Wi-Fi can also be useful.

    Can I use my eSIM to make calls via WhatsApp while in rural areas of Guam?

    +

    Using WhatsApp with an eSIM in rural areas of Guam is possible where adequate network coverage exists. However, remote regions may have spotty connectivity, possibly affecting call quality. Before you travel, review your provider’s coverage map for specific rural areas to gauge capacity. Having calls initiated in areas known for better coverage, such as around municipal centers, can mitigate issues.

    How does eSIM performance in Guam compare to nearby regions like the Northern Mariana Islands?

    +

    eSIM performance in Guam tends to be more robust than in nearby regions like the Northern Mariana Islands due to Guam's well-established network infrastructure and larger population centers. To optimize your experience, verify coverage specifics with your provider when planning travel across these areas. Be prepared for potential variability in network quality, especially in less populated islands or more remote areas.

    Is dual SIM functionality supported for travelers using eSIMs in Guam?

    +

    Dual SIM functionality is supported in Guam for most modern devices, allowing you to use an eSIM alongside a physical SIM. This can be particularly useful for travelers who need to maintain both a local and international number. Before your trip, confirm that your device is compatible with dual SIM technology and check if any settings need to be adjusted for a seamless transition.

    What should I do if I run out of eSIM data while exploring the Historic District of Hagåtña?

    +

    If you run out of eSIM data in the Historic District of Hagåtña, you can usually purchase additional data through your eSIM provider’s app or online portal. Alternatively, locate nearby Wi-Fi hotspots, often available in cafes or public areas, to stay connected temporarily. Planning to monitor your data usage can prevent running out unexpectedly, ensuring a smoother experience as you explore the district.

    Can eSIMs provide fast data speeds for video streaming at Tumon Bay hotels?

    +

    eSIMs generally offer fast enough data speeds for video streaming, especially in Tumon Bay, where the network infrastructure is robust due to the area's tourist popularity. Nevertheless, your streaming experience may still depend on your hotel's Wi-Fi quality and the specifics of your eSIM data plan. Verifying speed and plan details in advance ensures better service and helps manage expectations during your stay.

    Are there any eSIM compatibility issues with local carriers in Guam?

    +

    eSIMs are generally compatible with local carriers in Guam, though it's a good idea to check the compatibility with your specific device model and eSIM provider before your trip. This precaution helps avoid unexpected surprises related to frequency bands or network settings. By confirming details on your provider’s website or through customer service, you ensure smoother connectivity upon arrival.

    How does eSIM network quality affect online navigation apps while driving in Guam?

    +

    eSIM network quality in Guam is adequate for using online navigation apps, thanks to good coverage along major roads and urban areas like Hagåtña and Tumon. While planning your route, ensure a reliable internet connection, as network gaps are less frequent but still possible in remote or less populated areas. Downloading offline maps can serve as a backup for real-time navigation and ensure seamless travel.

    Is eSIM activation possible for travelers arriving late at the airport in Guam?

    +

    eSIM activation is indeed possible for travelers arriving late at Guam's Antonio B. Won Pat International Airport. The digital activation process can be performed at any time through your phone's settings once your device connects to a network. It’s convenient to activate upon arrival, but ensure your eSIM details are set up beforehand. If issues arise, airport personnel might offer assistance or access to Wi-Fi.

    How does eSIM coverage in Guam affect emergency contact ability during outdoor activities?

    +

    eSIM coverage in Guam is generally reliable, facilitating emergency contact during outdoor activities, especially in populated and tourist-prone areas. However, remote locations may offer limited coverage, which could affect communication. It's wise to prepare accordingly, perhaps by informing someone of your plans or using devices like satellite phones in areas known for poor connectivity to ensure safety in emergencies.

    What happens if my eSIM stops working while I'm on a boat tour around Cocos Island?

    +

    If your eSIM stops working while on a boat tour around Cocos Island, it's likely due to being outside the coverage range. Restart your device and attempt to move closer to the mainland to regain service. Having offline maps or guides can be a valuable backup in such scenarios, enabling you to continue navigation and keep informed about your surroundings without relying solely on connectivity.

    How can I check my remaining eSIM data balance while staying in Dededo?

    +

    Checking your eSIM data balance while staying in Dededo is straightforward via your provider’s mobile app or online account portal. Keeping track of your data usage helps avoid potential overages and ensures you remain connected throughout your visit. Set up alerts if possible to notify you of usage thresholds and consider opting for a plan upgrade if you anticipate high data requirements.

    Can I rely on eSIMs for consistent video call quality in Hagåtña?

    +

    You can generally rely on eSIMs for consistent video call quality in Hagåtña, thanks to the city's robust urban infrastructure. However, checking the signal strength before initiating a call ensures a stable connection. If you experience issues, relocating to a spot with better coverage or switching to a local Wi-Fi network can improve call quality. Optimizing settings for lower data usage may also help maintain clarity.
