Narrative:
Aircraft X called up VFR about at 9000 or 9500 feet to pick up an IFR clearance. He was radar identified and issued clearance with a descent down to his requested altitude of 7000 feet and then shortly after given a communications changes. After we were relieved from the sector we were called back to be learn that the aircraft had entered the northern section of a 7200 foot minimum IFR altitude (mia) and was not in communication range of either sector since their frequencies are highly marginal between these two airports. Although; another sector was able to relay quite quickly through another aircraft and issue the safety alert and climb.we have to constantly work as a team and help each other ensure that operations are safe at all times and avoid getting complacent. Alaska is filled with large areas where small aircraft even when flying IFR are unable to talk to ATC and in some cases there is no way to establish radio contact with the pilot. This situation was not a super busy session at all and should have been easily caught by one of us on the sector; which none did. We must never let our guard down and constantly double and triple check what trainees are issuing to these aircraft.
