There are two different things, UMTS and MPTCP. MPTCP is protocol and UMTS is physical channel. Let's separate them.
1)Does UMTS channel work? If not, using ping to debug the channel.
2)Does your distribution provide MPTCP installation package? What's your distribution?

Hi, i have installed many versions of ns2
but mptcp works only with newer versions not with ns2.29,
my problem is i don't know how the traffic moves from different access interfaces and how analyse it

In general, ns2 is network simulator. The traffic never go to real interface, just moving in memory.
