- In order to maintain network quality, telecommunications companies adhere to the Fair Use Principles (FUP) of Internet communications. Large amounts of traffic in a short period of time are easily automatically controlled, which may result in inability to access the Internet or slow Internet speeds. If the speed is reduced due to the Internet Communication Fair Use Principle (FUP), please contact technical customer service
- The network may change depending on the number of users, climate, building shadows, and location. If the reception is unstable, please be sure to contact technical customer service.
- The quality of telecommunications networks in different countries varies. The base station construction is not as dense as that in Taiwan. The regionality and telecommunications construction of each country are different. We are sorry that we cannot request a refund due to the signal conditions in a few areas.
