América Móvil reported a 1% year-on-year rise in service revenues at constant exchange rates to almost 194 billion Mexican pesos (12.6 billion US dollars) in the first quarter. The group said: "The deceleration observed by service revenues reflects, among other things, the impact of the various regulatory measures implemented in Mexico including the elimination of termination charges for calls that terminate on our networks, and of national roaming and long distance charges (the latter ones from January 1st) on both the mobile and fixed-line platforms."
"The South American block continued to be the main driver of service revenue growth—4.6% year on year at constant exchange rates—followed by Central America and the Caribbean with 3.8%. whereas in Mexico they were down 6% on account of the measures mentioned above. In the US, service revenues rose 7.3% and in Europe they were flat (at constant exchange rates)." source: América Móvil statement
