B737 flight crew experiences lost comm during approach to runway 5R at MMMX. Attempts at contacting approach control; tower (two frequencies) and ground control are unsuccessful and the crew elects to land without clearance. After landing and clearing the runway; communication is established with clearance delivery and clearance to the gate is issued. The crew is advised that the tower frequency has changed to 124.7.

Narrative:
During approach and landing at MMMX all communications with ATC were normal until not receiving the handoff from the final approach controller to tower. The first officer (non flying pilot) attempted two or three times to get the handoff but to no avail. We switched to the published tower frequencies and again no response on multiple attempts on the two published frequencies. We tried one of two ground control frequencies; again no answer; all these attempts were made on both VHF radios. As captain; I elected to land in VFR conditions with no aircraft on or near runway 5R. After landing and holding short of 5L we were able to get a hold of someone on the clearance frequencies that cleared us across 5L and to the gate. He also told us the operating tower frequency was 124.7 which was not published on the current chart or by NOTAM.
