I've found that there are few tech's who even work for the company they represent, that really understand their own products. The little phones that fit into your pocket only have a 1/4 watt output power and maybe a 1/2 watt for some in the most favourable conditions! You never had a dropped call in your older bag phone because you had a full 3 watt power antenna. there are a lot more people on the networks now and more crowded cells of traffic.
