    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 Thailand eSIM

    Everything you need to know about the Thailand 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 Thailand 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 Thailand?

    +

    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 Thailand. 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 Thailand.

    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 Thailand?

    +

    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?

    +

    Your eSIM can only be activated on one device. If you delete the eSIM from your device, you will not be able to reuse it. You cannot scan the QR code on two devices.

    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 Thailand

    +

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

    Connected from Bangkok’s Markets to Chiang Mai’s Hills

    Thailand, or ประเทศไทย, is a vibrant tapestry of bustling cities and serene landscapes. In Bangkok, the neon-lit night markets buzz with activity, a contrast to the peaceful, misty hills surrounding Chiang Mai. Phuket, with its beaches and gateway to Koh Phi Phi, offers a slice of island paradise. A typical trip might start in Bangkok's urban sprawl, wind through the cultural heart of Chiang Mai, and end with a relaxing island-hop in the south.

    Connectivity in Thailand is robust in urban centres like Bangkok and Chiang Mai, where mobile signals are strong and reliable. However, as you venture into the mountainous regions around Chiang Mai or the remote islands near Phuket, expect patchier coverage. National parks and some stretches of rural rail lines may also see reduced signal. The farther you drift from major thoroughfares, the thinner your connection might become.

    Before you fly

    For a smooth arrival, set up your eSIM before departure. Download essential apps and maps while on reliable Wi-Fi, ideally at home or in a major city. As you touch down in Thailand, expect to have reliable connectivity in urban areas, allowing you to effortlessly navigate from Bangkok's markets to the tranquillity of the northern hills.

    Using an eSIM in Thailand

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

    20 questions

    Will I have eSIM coverage when exploring the islands of Phuket and Koh Phi Phi?

    +

    Yes, you will generally have good eSIM coverage on popular tourist islands like Phuket and Koh Phi Phi. These locations have robust mobile network infrastructure to support the high volume of tourists. However, in remote areas such as secluded beaches or dense jungle trails on these islands, signal strength can vary. It's advisable to download offline maps and check the specific coverage maps provided by your eSIM provider before your trip.

    How do I activate my eSIM upon landing at Suvarnabhumi Airport (BKK) in Bangkok?

    +

    Upon landing at Suvarnabhumi Airport, ensure your device is connected to airport Wi-Fi or a temporary SIM. Follow the activation instructions provided by your eSIM supplier, which typically involve scanning a QR code and configuring network settings. Assistance is usually available at airport kiosks if needed.

    Can I use my eSIM on the train from Bangkok to Chiang Mai?

    +

    Yes, your eSIM should work on the train from Bangkok to Chiang Mai, a popular route serviced by reliable network providers. Coverage is typically strong in urban and peri-urban areas but may fluctuate when passing through mountainous regions like the northern highlands. Make sure your eSIM is activated and your plan has sufficient data allowance to stay connected throughout the journey.

    What should I do if my eSIM doesn't connect at Don Mueang Airport (DMK)?

    +

    If your eSIM doesn't connect at Don Mueang Airport, first ensure that airplane mode is off and mobile data is enabled. Restart your device to refresh network settings. If the issue persists, connect to the airport's free Wi-Fi to troubleshoot further or contact your eSIM provider's support line for assistance. It's beneficial to have your provider's contact information handy for such cases.

    Is an eSIM compatible with smartphones for exploring Thailand's rural areas?

    +

    Most modern smartphones support eSIM functionality, but first check if your device is unlocked and compatible with eSIM technology in Thailand. In rural areas like the northeastern Isaan region, network coverage can be sparse, affecting connectivity. Before your trip, verify coverage maps provided by your eSIM provider and consider downloading necessary information or maps for offline use to mitigate connectivity issues.

    +See all 20 questions

    Can I use an eSIM to make WhatsApp calls while visiting Chiang Mai's hill tribes?

    +

    Yes, you can use an eSIM for WhatsApp calls while visiting the hill tribes around Chiang Mai, but network coverage can be spotty in these remote areas. Since cellular infrastructure is less developed in mountainous regions, verify connectivity beforehand. It's a good idea to inform contacts about potential communication limitations and to plan key communications for when you have strong signal strength.

    How is network coverage on the Skytrain (BTS) in Bangkok?

    +

    Network coverage on Bangkok's Skytrain (BTS) is generally robust, providing strong eSIM connectivity for most of the journey. However, signal strength can weaken in underground sections or crowded stations like Siam or Asok. To avoid disruptions, ensure your eSIM plan includes adequate data, especially if you rely on apps for navigation or communication during your travels throughout Bangkok via the BTS.

    How can I troubleshoot if I run out of eSIM data while island hopping in Thailand?

    +

    If you exhaust your eSIM data while island hopping, first try connecting to available Wi-Fi networks at local cafes or accommodations in areas like Krabi or Koh Samui. Many eSIM providers enable online top-ups, which you can purchase using Wi-Fi. Before heading out, familiarize yourself with your provider's top-up options and payment methods to ensure you can smoothly extend your data plan if needed.

    Can I use my eSIM as a hotspot while traveling between Koh Samui and Koh Tao?

    +

    Yes, you can use your eSIM as a hotspot between Koh Samui and Koh Tao, provided your plan supports tethering and has sufficient data allowance. Be cautious, as using your phone as a hotspot can quickly consume data. Make sure to monitor your usage and disable the hotspot feature when not needed to conserve your allowance for essential activities during your trip.

    Will my eSIM work seamlessly when crossing the border from Thailand to Laos?

    +

    eSIM functionality can vary when crossing from Thailand to Laos. Check with your provider if they offer coverage in Laos, or if you'll need a separate plan for seamless connectivity. You may find it necessary to activate a local eSIM for Laos to maintain uninterrupted service. Researching and preparing for this beforehand will ensure you remain connected as you cross the border.

    How do I ensure my eSIM provides good data speed for video streaming in Bangkok?

    +

    To ensure good data speed for video streaming in Bangkok, choose an eSIM plan that offers high data limits and check reviews of the provider’s network speed in urban areas. Bangkok's city center, including areas like Sukhumvit and Silom, typically have strong network infrastructure for streaming. Verify with your provider about high-speed data availability, and adjust settings to prioritize video quality when needed.

    Why does my eSIM show no service when I'm at Chiang Mai International Airport (CNX)?

    +

    If your eSIM shows no service at Chiang Mai International Airport, check that your device settings allow roaming and mobile data access. Restart your device to reset network connections and ensure the eSIM profile is correctly installed. If issues continue, airport Wi-Fi can be utilized to contact your eSIM provider's support for further troubleshooting and resolution, helping you regain connectivity promptly.

    Is it viable to rely solely on an eSIM for data while backpacking through Thailand?

    +

    Relying solely on an eSIM for data while backpacking in Thailand is feasible if you confirm adequate network coverage across rural regions like Mae Hong Son or Nakhon Ratchasima. Choose a plan with ample data allowance to suit your needs, but keep contingency plans in mind. Consider having local SIM cards or access to Wi-Fi in remote areas where eSIM coverage might be limited.

    What should I consider when selecting an eSIM for a culinary tour in Bangkok's night markets?

    +

    When selecting an eSIM for a culinary tour in Bangkok's night markets like Yaowarat or Pratunam, consider one that offers reliable urban coverage and sufficient data for navigating and researching. Night markets are busy and fast-paced, so having a consistent connection helps with accessing maps and reviews. Verify coverage with your provider to ensure optimal performance and avoid data interruptions during your culinary explorations.

    Are there any specific steps for using an eSIM while visiting Thailand's national parks?

    +

    Before visiting national parks like Erawan or Doi Inthanon, confirm network coverage in these areas with your eSIM provider. Signal strength can be unreliable in remote park areas, so download offline maps and important information beforehand. Ensure your eSIM plan has enough data to cover unexpected connectivity dips, and consider alternative communication methods if you need to coordinate with others during your visit.

    How does eSIM data usage compare when traveling between urban Bangkok and rural Isaan?

    +

    While data usage remains consistent, coverage quality can vary significantly. Urban Bangkok is equipped with robust cellular networks supporting reliable eSIM connectivity, while rural areas like Isaan may experience patchy service. To ensure seamless communication, choose an eSIM plan that offers broad coverage across diverse regions of Thailand and make adjustments as needed based on the specific areas you plan to visit.

    What are the benefits of using an eSIM over a physical SIM while exploring Thailand?

    +

    Using an eSIM offers the convenience of avoiding physical SIM swaps, allowing for quick activation and easy management of multiple plans across Thailand. With eSIM technology, you can switch between carriers without the hassle of handling small physical cards. Ensure your smartphone is eSIM-compatible, which adds flexibility and seamless connectivity when traveling from bustling Bangkok streets to serene Chiang Rai landscapes.

    Can I use an eSIM for voice calls in Thailand, or is it data-only?

    +

    eSIMs are generally data-only, not supporting traditional voice calls directly. However, you can use applications like WhatsApp or Skype to make voice calls over data. For instances where traditional voice calls are necessary, consider supplementing your eSIM with a local SIM card or services offering Voice over LTE (VoLTE) functionality to accommodate all your communication needs while exploring vibrant Thai cities or tranquil rural landscapes.

    How reliable is eSIM connectivity when riding the Chiang Mai - Bangkok train?

    +

    eSIM connectivity on the Chiang Mai - Bangkok train is mostly reliable, mirroring the quality of local mobile networks. While the route offers strong connectivity through urban and semi-urban areas, expect occasional disruptions and weaker signals in more isolated regions like the mountainous terrain of the northern countryside. Verify that your plan covers nationwide networks, ensuring consistent service throughout your train journey in Thailand.

    Is it necessary to have a local eSIM provider when visiting Thailand's less-traveled regions?

    +

    In less-traveled regions, such as the remote areas of the Golden Triangle, a local eSIM provider might offer better coverage. Global eSIM plans may not extend adequately into these sparsely populated zones. To ensure continuous connectivity, check regional coverage maps and consider utilizing local providers if international eSIM options fall short. This preparation helps maintain connection in areas where network infrastructure might be limited.
