| AT&T | 7257 Wedel Cemetery Rd | For about the last 6-7 months, signal strength shown on iPhone has been '1-bar' when indoors, pretty much anywhere in the local area surrounding Heidenheimer, Tx. Long delays of several hours and longer are typical when sending/receiving SMS. Calls, incoming and out-going, are almost impossible, even on clear, sunny days, and usually go to the respective voice-mails without the voice-mail being received by the intended party. | 2015 |
