Am screwed too, I have one and a half months left of my three months subscription just to wake up to a blocked UDP port (53). I happened to have the  another orange modem that uses UIM card instead of the orange SIM card. the orange UIM card network seems to have the port still working but the biggest downside of this uimcard is that it disconnects after every 5-10 mins and there seems to be no way to help it.
