Understanding what unlimited eSIM is and how it works has become increasingly important as mobile technology evolves. An unlimited eSIM combines the flexibility of digital SIM technology with unrestricted data plans, offering a modern solution for staying connected. This revolutionary technology eliminates the need for physical SIM cards while providing seamless access to mobile networks worldwide.

An unlimited eSIM is a digital SIM solution that offers unlimited data for a specific period. Unlike fixed-data plans (such as 5GB for 30 days) which require renewal or a top-up once the data is depleted, unlimited plans provide continuous data access throughout the selected period.
This type of plan is designed for users who need constant connectivity while traveling or working.
While the term “unlimited” suggests no restrictions, it is important to note that “unlimited” does not always mean limitless in every sense. Many providers include certain limitations, such as reduced speeds after a set amount of high-speed data is used.
The reason behind this restriction is that many providers implement a Fair Use Policy (FUP), which slows down the Internet speed after a certain amount of high speed data usage is reached.
An unlimited eSIM works by being digitally activated on your device through a QR code or an activation code provided by the eSIM provider. Once activated, it connects your device to a local mobile network automatically, offering internet access without needing a physical SIM card. This convenience is ideal for frequent travelers, remote workers, or anyone who needs reliable connectivity.
For example, a plan may offer unlimited data, but only the first 25GB or 50GB will be at high speed (e.g., 4G or 5G). After that threshold, the speed could drop to 128 Kbps or 256 Kbps, which is only suitable for basic activities like email or messaging.
However, not every provider mentions these details in their advertisements, leaving users in the dark about the actual speed constraints.
Knowing the limitations of an “unlimited” eSIM plan helps users make informed decisions. If you rely on high-speed data for work or entertainment, understanding the throttling limits of your plan is essential to avoid frustration. Always check the terms and conditions before purchasing to ensure the plan meets your needs.
Unlimited eSIM brings major improvements to mobile connectivity.
When comparing unlimited eSIM and limited eSIM, the main differences generally revolve around the scope of data, validity, and usage. Here’s a detailed comparison:
| Feature | Unlimited eSIM | Limited eSIM |
|---|---|---|
| Data Usage | Unlimited (may throttle speeds after high-speed data usage based on Fair Use Policy) | Fixed data limit (e.g., 5GB, 10GB) |
| Validity Period | Often offers longer validity (e.g., 30 days with auto-renewal options) | Tied to the data limit or shorter periods |
| Cost | Higher due to unlimited data and flexibility | Generally more affordable, as the data allowance is capped. |
| Flexibility | Ideal for heavy users who need constant connectivity | Ideal for tourists or short-term needs. Suited for light/medium usage like browsing or occasional use. |
| Speed Restrictions | Some providers throttle speeds after reaching a certain usage threshold (fair-use policy). | Stops entirely once the limit is reached |
| Use Cases | Great for travelers needing continuous connectivity, frequent business travelers, or people needing high bandwidth. | Better for tourists, budget-conscious users, or those with specific short-term data needs. |
| Roaming Support | Many unlimited eSIMs include worldwide or regional roaming. | Limited eSIMs may have restricted coverage or additional roaming charges. |
| Renewal Options | Often auto-renewable monthly plans. | May require manual top-ups or re-purchasing new plans. |
► Recommendation: Unlimited eSIM clearly represents the future of mobile connectivity, offering superior flexibility, convenience, and environmental benefits compared to traditional SIM cards. While device compatibility remains a consideration, the advantages of digital management and instant global connectivity make it an increasingly attractive choice for modern users.
Yes, unlimited eSIM plans have a set duration (e.g., 8 days, 30 days). Once this period ends, the service stops unless renewed. Additionally, while data access remains unlimited during the validity period, the speed may reduce after a certain high-speed data threshold.
Check your plan’s terms for specific validity periods and renewal options.
1. Check cevice compatibility: make sure your phone supports eSIM (iPhone 11+, newer Samsung Galaxy, Google Pixel). See detailed guide to check phone supports eSIM.
2. Choose a reliable provider: compare and select from providers like Gigago. However, the unlimited eSIM plans are only available in some specific eSIM plans of specific countries, not all. Look for the destination you want to visit, and check if there is any unlimited plans are available (and also read carefully the description). If not, you need to use fixed plans as alternative.
3. Buy and activate: buy the plan, scan the QR code to install and activate it when you arrive in your destination.
4. Test connection: browsing the web to test if things work.
Not always. Many providers throttle speeds after a certain amount of high-speed data is used. Check the Fair Use Policy or plan details for specific limits.
No. These eSIMs are data-only plans – they don’t include calling or texting capabilities. You’ll need to use internet-based apps (like WhatsApp, Skype, or FaceTime) for communication.
Yes. eSIMs work on any compatible tablet or laptop, providing mobile data without a physical SIM card. Check your device’s settings menu or manufacturer’s website to confirm eSIM compatibility and find setup instructions.
