My father drives a taxi. What mobile phone is suitable for him?

Nokia 6208 is quite good, with a metal body and good quality. This mobile phone is dual input by handwriting keyboard, which is more suitable for those who can't type with keyboard. And the font of this mobile phone is relatively large (some mobile phone fonts can be adjusted). In fact, handwritten mobile phones are not necessarily good. Handwritten mobile phones are generally intelligent business machines, which are relatively complicated to use and are not suitable for people who are not familiar with mobile phones.
