Buy the perfect eSIM for your trip in simple three steps:

First, choose the data plan that best suits your travel needs.
Second, securely complete your payment using the trusted PayPal gateway.
Finally, receive your QR code via email in as little as 15 minutes.

Regrettably, eSIM Singapore exclusively provides data-only plans, which do not encompass local phone numbers. Consequently, these eSIM packages do not support voice calls or SMS. Should you need voice call and SMS functionalities, we recommend utilizing VoIP (Voice over Internet Protocol) services such as Skype or other messaging applications that depend on data connectivity for calls and messaging.

Yes, you have the option to keep your WhatsApp number, along with all your conversations and contacts, when using an eSIM.

Currently, we only accept payments through PayPal. If you don’t have a PayPal account, we highly recommend creating one. It’s a simple process that can streamline your payment transactions.

Once your payment has been successfully processed, our eSIM QR code will be automatically sent to the email address you provided, typically within just 15 minutes. If you do not receive it within this time frame, please consider the following steps:

01. Check Spam or Promotion Folders: Be sure to inspect your spam or promotion folder, as it’s possible that your email may have been filtered there.
02. Contact Us for Assistance: If you suspect there might be a typo in your email address or if you have any other concerns, please feel free to reach out to us at [email protected] for a quick reissue.
03. Payment Processing Delay: If you used iDEAL or another non-PayPal payment method, there may be delays during the transfer to PayPal. In such instances, we recommend contacting the respective payment gateway for assistance.
04. PayPal Security Measures: It’s important to note that PayPal may occasionally subject your payment to security checks, which can take up to 72 hours. This is part of PayPal’s security protocol. For guidance in this regard, please contact PayPal’s customer service.

Please be aware that even for credit or debit card payments, the processing is routed through PayPal, which may involve PayPal’s security checks and a pending status. For additional assistance, we recommend getting in touch with PayPal’s customer service.

To monitor your data usage, you can access the settings on your device. For detailed information on data consumption, please reach out to us at [email protected]

The process may vary depending on your device’s manufacturer:

Apple Devices
1. Open [Settings]2. Select [Cellular/Mobile Data]3. You can check your data usage under “Current Period Roaming.”
4. Alternatively, detailed instructions are available on the Apple website here.
You can also dial 1019# to check your data usage via a call

Samsung Devices
1. Access [Settings] – [Connections]2. Select [Data usage]3. Your mobile data consumption will be displayed
4. You can also dial *101*9# and make a call to check your data usage

Google Devices
1. Open [Settings] – [Network & Internet] – [Internet]2. Tap [Settings] next to your operator
3. At the top, you’ll see the total data you have used

To verify the activation of your eSIM, watch out for these two crucial indicators:

eSIM Profiles
Go to your device’s eSIM settings, where you’ll find a list of available profiles or plans. Once your eSIM is successfully activated, you will see an active profile without a listed phone number among the options.

Signal and Connectivity
After your eSIM is activated and connected to a cellular network, you should see signal bars or connectivity icons in your device’s status bar. Additionally, you might notice the carrier name associated with the eSIM, confirming both its activation and network connection.

Yes, it is essential to enable data roaming for your secondary line, which is your added eSIM plan. To activate data roaming, please follow these steps:

For Apple Devices
1. Go to [Settings] – [Cellular]2. Choose the [Secondary] (the eSIM plan you’ve added)
3. Ensure that [Data Roaming] is switched to the ON position

To prevent unexpected charges, it’s important to disable the automatic switching of lines.
Here’s how to do it on Apple Devices:
1. Go to [Settings] – [Cellular]2. Tap [Cellular Data]3. Make sure that [Allow Cellular Data Switching] is turned OFF

We also recommend reaching out to your domestic carrier to inquire about “Blocked charged international roaming” services. This will help ensure you have the most suitable data options in place when using the eSIM plan.

It is strongly recommended to deactivate your original SIM to prevent incurring data roaming charges from your domestic carrier while using the eSIM. Deactivating your original SIM ensures that your device exclusively utilizes the eSIM for data connectivity during your travels.

However, if you prefer to continue receiving calls and SMS on your home number while using the eSIM, you have the option to keep your original SIM active. In such cases, we recommend disabling the “Automatic Cellular Data Switching” feature on your device to prevent unintentional data usage, ensuring that data traffic is routed through the eSIM plan rather than the original SIM

When your data is exhausted or the validity period expires, internet access will be suspended. If you wish to extend the validity or acquire additional data, topping up is a simple process. You can locate the “Make a Top-up” button in the email that contains the QR code.

Unfortunately, we do not offer refunds for eSIMs that have been activated and used for data. Once activation and data usage have taken place, it aligns with our policy, which does not permit refunds in such cases. We strongly advise customers to thoroughly review their plan details before proceeding to avoid any potential inconvenience.

Our dedicated customer support team is available 24/7 and is ready to help with any inquiries or concerns regarding your eSIM plan or its usage.
