To the Editor:

The Sunday, October 3l, Boston Globe had an article datelined Katmandu, Nepal, and headlined “Cellphone service reaches the top of the world.” Two years ago, I was birding in Bolivia from the lowlands of Santa Cruz to the 11,000-foot high city of LaPaz, and all parts in between. This was during a nasty political insurrection. I was in cellphone contact with my concerned wife at all times and locations through our home phone in Chilmark. Cellphones do not work in most of Chilmark. Menemsha? Town center? The beaches? Why not? Our safety is on the line.
