| Sprint | 158 N Glendora Ave | Phone calls do not ring through to my phone - go straight to voicemail... lots of poor reception area in Glendora along foothill corridor between Glendora Ave and Elwood; quadrant bordered by Meda on the south, Glendora Ave. on the west, and live oak on the east - all the way to the foothills! Very frustrating! | 2019 |
| AT&T | 439 E Bougainvillea Ln | Used to have AT&T coverage years ago. Then they sold the cell site to t-mobile. only reason I kept service was coverage in other areas. Still sucks in glendora. | 2019 |
