I think Vodafone has the best signal because it is the only signal that could be detected in basement, or underground. I know a lot people signed contract with Telfort, KPN or other companies, and they don't have signal there. Unfortunately, Vodafone usually has higher price than other company. Unless you really need calling in basement, I think signal quality is not really important as long as you can have it in normal buildings. So far as I know, Debitel (may not be written correct) is the only signal that is too bad to be acceptable. Normally, the signal provider plays more important role than your mobile phone itself. |
