An eSIM, also referred to as an embedded SIM, digital SIM card, or virtual SIM card, is a cloud-based mobile identity that allows users to activate and manage multiple cellular plans on a single device. It eliminates the need for a physical SIM card, offering the convenience of using several cellular providers on one device. eSIM enhances flexibility by enabling features such as adding an extra line for international travel and managing distinct data plans for personal and business use.

You can check your data usage through the email you received after purchase. It includes a link that directs you to your data usage details.

To connect to the internet using the Ottersim eSIM:

1. Navigate to your device's Mobile Data settings.
2. Enable eSIM that you have purchased from Ottersim
3. Activate Data Roaming if needed.
4. Select Ottersim's data as your primary connection.

Do NOT delete your eSIM, as it will be permanently removed and cannot be reinstalled or used again.

If you purchase an eSIM from Ottersim with 1GB of data daily for 5 days, you will receive 1GB of data each day. In contrast, if you opt for an eSIM with 1GB total for 5 days, you will have 1GB of data to use over the entire 5-day period.

Yes! It’s truly unlimited! When your high-speed data runs out, you’ll still have unlimited data at 128Kbps—perfect for WhatsApp, email, and other essential apps.

Each QR code is a unique identifier intended for single-use and specific to a particular device. Once activated, it cannot be reused on any other device or on the same device after the eSIM profile has been deleted. This security measure ensures the QR code is exclusively used for its designated device.

Our Ottersim prepaid eSIM plans are tailored for data usage and do not include a traditional phone number. For voice calls and text messaging, we recommend using VoIP apps such as Facebook Messenger, WhatsApp, Viber, Telegram, or Skype. This enables customers to stay connected globally without the necessity of purchasing a standard international SIM card from mobile operators or carriers while traveling.

Absolutely! You can continue using WhatsApp, Snapchat, Telegram, and other messaging apps with Ottersim's eSIM. Ottersim is designed to provide seamless data services without interfering with any apps.

Sharing mobile data with other devices using Ottersim is simple. Just install the eSIM on your device and activate Personal Hotspot in the settings. This feature is automatically enabled on your account at no extra cost, although data used while tethering will be deducted from your plan.

The eSIM data plan activates as soon as data roaming is turned on. If you're not using your mobile data right away, we advise waiting to enable data roaming for Ottersim's eSIM until you reach your destination. Please note: Ottersim's data services begin at UTC+8. Enabling data roaming at 11:30 PM UTC+8 provides just 30 minutes before the day's validity expires. We suggest adjusting your timing to optimize your data usage.

The speed of mobile data is influenced by several factors, including the type of smartphone, available network technology, accessed websites or apps, time of day, network congestion, transmission path conditions, and local cell tower usage. Download and upload speeds are also affected by the country's network infrastructure and broadband connection type. Slow internet speeds are often linked to inadequate coverage by the country's mobile operator. To improve data speed, consider these tips:

• Restart Your Device: Sometimes, a simple restart can refresh your connection and improve speeds.
• Check Network Signal: Ensure you have a strong signal by moving to an area with better coverage.
• Disable Background Apps: Close apps running in the background to conserve data and potentially enhance speed.
• Switch Network Modes: Experiment with switching between 4G/LTE and 3G modes to find the optimal performance.
• Clear Cache: Clear app cache and data periodically to resolve speed issues caused by temporary files.
• Update Software: Keep your device's operating system and apps up to date to benefit from performance enhancements and bug fixes.

Ottersim's prepaid data plans are contract-free and do not include any roaming fees. You only pay for the data you use based on the purchased eSIM plan.
