Choose a GPRS tariff model that suits your needs the most because the internet traffic is charged according to the amount of transferred data and not according to the duration of connection.

General Packet Radio Service enables you to access WAP pages with useful information and complete access to all internet services (e-mail, web pages, software libraries) by connecting your GPRS mobile phone to a laptop computer, connecting it to the service provider of your company from any place. You are thus able to access your business documents you may need while you are out of office. If you wish to read e-mail via GPRS, you will pay for the service depending on the amount of data transferred regardless of how long you have accessed your e-mail for. Thus you are able to foresee costs, unlike logging on to internet via CSD.

All T-Mobile users, without special activation, can use the Free surf tariff model. Free surf is a service included in the tariff bundle.

If you do not have a need for voice calls and are using your mobile phone only for data transfer (SMS, GPRS, CSD, fax) and internet access, the real substitution for fixed-line internet is the tariff model Mobile Internet.
