        2. What is Unlimited Data Plan? No restrictions?

        Unlimited data plans are a popular option for those who want to enjoy unrestricted internet access. However, "unlimited" does not always mean "unrestricted." Often, an "unlimited data plan" is a marketing term used by internet service providers to mean offering internet access without cutting data caps. When a user exceeds a certain data cap, the provider will start bandwidth throttling to reduce the speed at which the user can access data, thereby slowing down the user's internet usage. Specific rules and thresholds vary by provider, and MicroEsim is actively testing these limits to provide updates.


        3. What is Fair Usage Policy (FUP)?

        Telecommunications companies implement Fair Use Policies (FUP) to prevent network abuse. If you consume an unusually large amount of data in a short period, your provider might throttle your speed or temporarily disconnect your service. According to our observations, speeds may be throttled if usage exceeds 10GB to 20GB in a single day. This threshold varies according to local providers.

        We are testing the wireless data speed limits of various mobile phone providers and will update the blog with any findings. To avoid triggering the fair use policy, it's advisable to avoid prolonged video streaming or processing large amounts of data in a short time.


        4. Data Plan Options: “Terminate Data Plan” or “Unlimited Data Plan”

        Choosing between multiple data plan types can be confusing. Below you will understand the circumstances under which each plan is most beneficial, helping you make an informed choice based on your travel and data needs.

        Terminate Data Plan - Stop after High-Speed Data is Used Up

        The Terminate Data Plan means that your internet connection will stop when your high-speed data is used up. With this type of data package, you have a set amount of high-speed data. Once you exhaust this data, your internet connection will be cut off until you purchase additional data. This plan can be cost-effective if you have predictable and moderate data usage and is suitable for users who primarily use data for activities that do not require continuous high-speed internet, such as occasional browsing or checking emails.

        Considerations: There is no guarantee of unlimited low-speed data after your high-speed data is used up. You need to monitor your data usage closely to avoid unexpected disconnection.

        Unlimited Data Plan - Unlimited Low-Speed after High-Speed Data is exhausted

        Unlimited data plans allow you to continue using the internet at a lower speed after your high-speed data is exhausted. This option ensures you stay connected without additional costs, making it ideal for users with high data demands.

        Considerations: While you can continue using data at reduced speeds, activities that require high-speed internet, such as HD video streaming or online gaming, may be affected. Ensure that you are aware of the specific fair use limits set by your provider to avoid unexpected speed reductions.


        5. What can you do with different FUP Internet speeds?

        MicroEsim offers a variety of FUP (Fair Usage Policy) options, allowing you to maintain your network connection after the high-speed data is used up. Internet speeds under FUP can vary, affecting what activities you can perform online. The following describes the low-speed traffic and its availability under different FUPs:
