in my case. my 2 sisters use globe. every time they call our smart lines be it the pre paid or post paid line. you won't hear each other on the first call... never misses. been like that for more than a year. but when i make the call smart to globe... first call goes well... don't know which network is at fault.

yung sun well mahina signal dito so talagang dropped palagi, either i go up to the second floor or go out to the garage to get a good signal.
