Narrative:

VFR flight from ZZZ airport to ZZZ1 airport. I inquired customs officials where to file a flight plan. They said most pilots would depart and file with ZZZ2 radio. I could not make pay phone at terminal work. FBO location remote and did not appear to have an office. I took the local advice and departed VFR. After departure, attempted to contact ZZZ2 radio on frequency -- no answer. Contacted ZZZ3 radio on frequency. They said 'extremely busy, standby.' soon there after, ZZZ3 radio started giving out numbers (aircraft X standby, you're no 8). I switched back to ZZZ2 approach frequency, they answered and asked my altitude 10500 ft said I was above their airspace, contact ZZZ5 center frequency. I called ZZZ5 center several times, could hear him talking to other aircraft, but would not reply. Called ZZZ3 radio again and asked for a number, said I was '#4, standby.' a few mins later he got to me. I requested he give commercial service my arrival ZZZ4 airport XA40. He said he would call 'because I had a to wait.' I did not try to air file a flight plan. Continued VFR to ZZ4 airport squawking 1200. Contacted ZZZ4 tower 10 mi southeast descending through 2000 ft. He said report midfield right downwind. Approximately 5 mi southeast of airport intercepted by 4 F16's, one with gear down. ZZZ4 asked if I had F16's in sight affirmative. Tower then cleared me to land. I perceived airfiling would be easy. I have done so before in continental us several times. I should have filed a flight plan from my hotel with reliable phone service and I should have landed and filed a flight plan in ZZZ2. Deciding to continue VFR to my original destination across the ADIZ with incorrect. I should have known weekend traffic would be heavy. Crossed ADIZ without a flight plan.
