## Abstract

The present disclosure relates to a telecommunication method for controlling data access to a telecommunication server, the telecommunication server being connected to at least one client terminal via at least a first digital cellular telecommunication network, wherein the telecommunication server and the client terminal communicate via a stateless protocol, the client terminal being a battery powered device. The method comprises providing an electronic document having a plurality of input fields for entry of a set of user data; storing by the telecommunication server a status parameter in association with the electronic document, the status parameter having a first, second or third value, the first value indicating a first state of the electronic document in which the electronic document is not filled, the second value indicating a second state of the electronic document in which the electronic document is filled with the set of user data, the third value indicating a third state of the electronic document in which the electronic document is being requested for modifying at least part of the set of user data.
