There is always an INFORMATION frequency for the FIR (or a FIR sector), and them's the one you activate your flight plan with when in uncontrolled airspace; then just keep in touch with them and get eventually handed over. When you arrive at the FIR boundary (whether on time or not), you will usually have already been asked by the ATC to report passing a certain point, or, just as frequently, the ATC will call you as you are leaving their area and hand you over to the next FIR.
For example, if you have been asked to report DIK, just report it:
"BRUSSELS INFORMATION, EI-EIO overhead DIK".
ATC will tell you what to do next:
"EI_EIO Contact LANGEN INFORMATION at 123.525".
If you haven't been asked anything and haven't been called by the ATC when approaching the FIR boundary, you may want to say:
"BRUSSELS INFORMATION, EI-EIO overhead DIK, request frequency change to LANGEN", assuming you've done your homework and know what FIR you are flying into. The ATC will usually automatically give you the frequency.
You read it back, switch to the right frequency, and say:
"LANGEN INFORMATION, EI-EIO"
"EI-EIO, go ahead"
"EI-EIO PA34 en route from EIWF to EDKB, overhead DIK, altitude 1500 on QNH 1017"
"EI-EIO radar contact, squawk 3704"
"Squawk 3704 EI-EIO"
That's it.
And for chrissake, don't forget to close your flight plan once landed, or cancel it shortly before landing:
"LANGEN INFORMATION, EI-EIO destination in sight, request frequency change to EDKB and cancelling my flight plan"
"EI-EIO frequency change approved, your flight plan is cancelled at 1545. For your information, local QNH is 1016"
(or "your flight plan is cancelled at 1545, contact HANGELAR INFO 135.150")
