"The 'block now' feature only works with visible numbers. For nuisance calls from abroad you have to block ALL international calls, meaning you cannot receive ANY calls from abroad. Same applies to withheld numbers, they cannot be blocked unless you block ALL withheld numbers.
After 3 weeks, all incoming calls phone gave one ring and then stopped.
Customer services were helpful but could not solve problems. Reset the device twice but with no success. Would return, but cannot find the receipt."
