1. A method performed at a network device for sending data to and receiving data from a cellular network, the method comprising:
a. establishing a first cellular connection by using a first wireless communication module (WCM) and a local Subscriber Identification Module (SIM);
b. establishing a first data connection with a SIM bank via the first cellular connection;
c. downloading a SIM profile of a remote SIM from the SIM bank;
d. establishing a second cellular connection by using a second WCM and the SIM profile;
e. establishing a second data connection with the SIM bank via the second cellular connection;
f. disconnecting the first cellular connection; and
g. establishing a third cellular connection by using a third WCM and the local SIM;
wherein;
the local SIM is housed in a local SIM interface or is an embedded SIM;
the second cellular connection and the third cellular connection are aggregated to establish an aggregated data connection with an aggregation server; and
the network device is configured to establish a third data connection with the SIM bank via the aggregated data connection.
