Re ”The Quagmire of Making International Cellphone Calls,” by Joe Sharkey (On the Road column, Business Day, Oct. 17):
If Mr. Sharkey thought he had difficulty deciphering the international cellphone networks, he should try buying a cellphone that works with hearing aids.
Effective Sept. 16, the Federal Communications Commission mandates that cellphone providers must offer at least two handset models that have a minimum M3/T3 rating. The M rating (M3 or 4) represents microphone interference on a hearing aid and the T rating (T3 or 4) represents the hearing aid telecoil compatibility level. The higher the rating, the better.
