What does ttyUSB mean? Sometimes, the embedded microcontroller does not come with a hardware USB interface. While it is possible to use a software-only USB stack, the additional constraints put onto the CPU and the usually small storage size often lead board designers to include a dedicated UART to USB bridge.
Because of a busy weekend I didn't really follow up other than via emails and this still hasn't been resolved. The consistent word from them was that porting a number sometimes takes 24 to 48 hours.. I spoke to a rep by phone today who promised it would be done within 2 to 4 hours.. It wasn't.
Great question. WLNP (Wireless Local Number Portability) laws require that carriers comply with specific regulations regarding porting numbers in and out. Whether it's a prepaid or postpaid account, the reliability is the same. Your desire to test out a prepaid service and then port your number to the prepaid plan if you like it is very wise. You really shouldn't have any issues doing that. A few things to keep in mind: - Definitely don't cancel your old plan before porting your number out.
