Narrative:

I was combined everything for the cleansing of the cab. Aircraft X landed runway xx left; and while rolling out I checked for their gate. They were going to the ramp as they must have been an international arrival. I issued them keep their speed up to tango; traffic two miles in trail; then taxi via bravo to the ramp and to contact ramp prior to bravo [X]. They read it back. Once they exited; I resumed my end of shift clean-up before the first mid shift person showed up in about 7 minutes. There were no other aircraft to work. I gave that next arrival the same instructions (to the ramp via bravo) and left out the ramp contact as they are regular users of that ramp control.as I continued to clean; the line rang from ramp tower. When I answered they asked me to have aircraft X call them as the flight was taxiing in without communicating with them. I hung up the line and tried aircraft X. The second call they answered and I told them they should have called ramp control at bravo [X]. The pilot communicating said 'we are working on it.' I have thoroughly provided anyone going into the ramp; while the other ramp closed until traffic picks back up; with the exception of air carrier X and air carrier Y aircraft the exact communication changeover stated in the previous narrative. I really do not know what else I can recommend other than them calling as described and read back.
