Purchase Notice

  • Hotspot sharing consumes bandwidth, and network speed may vary depending on the device and geographical location. Therefore, a minimum network speed cannot be guaranteed. Please confirm before placing your order.
  • In order to maintain network quality, telecommunications companies strictly adhere to the principle of fair use of network communications. Controlling large amounts of network traffic within a short period may result in internet access disruptions or slower speeds.
  • To avoid violating the principle of fair use, it is recommended that any high-bandwidth network activity be conducted in a Wi-Fi environment, as follows:
  • Large-scale file transfers (uploading/downloading), watching videos, (watching) live streams, playing mobile games, and social media primarily consist of videos and photos; using these activities to a certain extent is equivalent to watching a large number of videos. It is also recommended to disable automatic updates and backups, automatic playback on social media, satellite map navigation mode (normal navigation mode can be used), and cloud drive data transfer functions.

  • Telecommunication network quality varies by country, with differences in base station density. Each country possesses its own unique regional and telecom infrastructure. Refunds cannot be requested due to signal conditions in specific areas

  • There might be restrictions imposed on irregular data usage (reaching 2–5GB per day), leading to slower or disconnected internet

  • To avoid violating the Fair Use Policy, please use Wi-Fi for activities that require large amounts of data, such as:

  • For mass file transfers (upload/download), video streaming, live broadcasts, mobile gaming, etc., it's recommended to disable automatic updates, backups, social app autoplay, and satellite map navigation (use standard mode). Additionally, please avoid transferring data via cloud drives

  • Fair Usage Policy (FUP) is a standard implemented by governments and telecommunications companies to protect the rights and interests of local users' Internet access. If you have concerns about the FUP policy, please book a fixed daily data or total data package
