Hi,
Can you please explain how you will call the CLD via a phone call using a SIM? Also, what do you expect - the telephone number?
Also, here are the corresponding FAA records with the comm frequencies:
When something is wrong, please report it to the FAA because we use these offered frequencies.
Last, when you report an issue or a question, please look at the FAQ page on how to do this correctly.
Thank you very much
Richard
