Why Does Speed Drop Occur in Unlimited eSIM Packages? Here Is What Is Wondered

About eSIM packages, which have recently become one of the most preferred internet solutions for users traveling abroad, one of the most frequently asked topics is the speed changes experienced in unlimited packages. Experts state that the speed drops seen in unlimited internet packages are not unique to a specific brand or service provider, but are a standard network management policy applied by the vast majority of operators worldwide.

Is There Really a Quota in Unlimited Packages?

Users can often interpret the expression "unlimited" as continuous high-speed internet without any usage limit. However, a significant part of unlimited packages in the mobile communication sector is offered within the scope of Fair Usage Policy (FUP). In this system, no limit is placed on the total daily data usage. The user can use tens or even hundreds of gigabytes of data during the day if they wish. However, if the determined high-speed usage quota is exceeded, the connection speed can be reduced. For example, in many international roaming and eSIM services, the first few gigabytes of the day are offered at maximum speed, and after that, although internet access continues, the speed is reduced to a certain level. In the unlimited packages offered by eSIMfo, there is also no total daily data usage limit. Even if users use 100 GB or more of data during the day, their internet access is not cut off. However, within the scope of the Fair Usage Policy, the first 3 GB of usage of each day is offered at maximum speed, and after 3 GB, the connection speed drops to the level of 1 Mbps. This speed limit is automatically renewed every 24 hours and users regain their right to high speed.

Is This Practice Only Present in eSIM Services?

No. Fair usage policies are applied not only in eSIM services but also on physical SIM cards in many countries and in unlimited packages offered by mobile operators. Especially in networks where intensive data consumption is experienced, operators can apply speed management after certain usage levels in order to provide a balanced service to all subscribers. For this reason, speed drop is accepted as a network optimization method widely used in the sector. It is possible to see similar practices in most of the unlimited packages offered with international roaming services, travel eSIMs, and physical SIM cards. Therefore, it is important for users to examine the package details before purchasing.

Can the Internet Be Used When the Speed Drops?

Yes. Internet access is not cut off after the speed limit. Users can continue to use their connections. Reduced speeds generally remain at a sufficient level for daily needs such as;

  • WhatsApp and Telegram messaging,
  • Social media usage,
  • Map and navigation applications,
  • Email transactions,
  • Internet browser usage,
  • Music listening services

remaining at a sufficient level for daily needs.

Which Packages Are More Suitable for Those Who Want Continuous High Speed?

Mobile internet usage habits can vary from user to user. While unlimited packages offer a very advantageous option for social media, messaging applications, and daily internet needs, it is recommended that users who perform operations requiring continuous high speed throughout the day evaluate different package types. Especially for users who perform data-intensive operations such as high-resolution video uploading and downloading, large file transfers, live broadcasting, or long-term high-quality video watching, high-speed packages with a specific data quota may be more suitable. Since internet access is offered at maximum speed until the usage right ends in quota packages, users who want to use the internet throughout the day without experiencing a speed drop can choose such packages according to their travel plans and data needs.

Is Hotspot Usage Possible?

Another topic that users are curious about in unlimited packages is internet sharing, that is, the hotspot feature. Unless restricted separately by the operator to which the package is connected, hotspot usage is supported in many unlimited eSIM packages. Thus, users can share their internet connections with their tablets, laptops, or other devices. This feature provides important advantages especially for users who use more than one device during travel, want to work from their computers, or plan to share their internet connection with their families.

Operator Policies Become Determinant

Sector representatives state that the speed policies applied in unlimited packages are determined not by the service providers, but by the network management systems of the local operators in the countries where the service is offered. For this reason, similar speed management practices appear as standard in international roaming services, eSIM platforms, and some physical SIM card packages worldwide. Experts advise users to check whether there is a total usage limit, the amount of daily high-speed usage, and the connection speed offered after the speed drop when evaluating the expression "unlimited internet". Thus, it becomes possible to choose the most suitable package for the travel plan and internet usage habits.
