The access to mobile internet is a mobile service available to all customers who have signed a contract with Yettel to use this service.
Depending on your mobile phone’s capabilities, you can restrict the access to mobile internet or to choose to use only Wi-Fi networks.
Please, bear in mind that most smartphones support such a restriction but restriction on behalf of Yettel is not applied.
Possible reasons for additional charging:
- Being in a no Wi-Fi area but the access to mobile internet has not been restricted from the phone’s menu
- Settings of an application or a program installed to your phone which require access to mobile internet through the network of the operator and may initiate internet sessions
When installing a new application on your smartphone pay attention to notifications referring to which system settings and functions the application has an access to. Check also currently installed applications on the same access rights.
For example, an access classified in your Android phone, such as:
is a possible reason for initiating internet sessions, even if you have selected only Wi-Fi networks and stopped the access to mobile internet from the phone’s menu.
