In a telecommunication network, a method is carried out for assisting a first user terminal (1001) in benefiting from a data connectivity. A second user terminal (1002) indicates (s10), to a connectivity donation server (200), that it is willing to sponsor data connectivity of the first terminal (1001) and that, restriction(s) are imposed on how the sponsored connectivity can be used. The restriction(s) comprise: i) where the first terminal (1001) is to be located for benefiting from the sponsored connectivity; and ii) which access network(s) the first terminal (1001) has to connect to for benefiting from the sponsored connectivity. The connectivity donation server (200) then transmits a token to the second terminal (1002), which in turn transmits (s30) it to the first terminal (1001) using proximity-based means. Terminals, network nodes, and computer programs for use in the above method are also disclosed.
