In have two confusions about the CC864-SR module (CDMA)
1. When i want a internet connection the userid & password are must. But if someone unknowingly change the RUIM then it never connects.
2. There is no delivery ok acknowledgment of data. If my device is a only transmitting device then how could it know which data were deliverd and which not.
