I do apologise if the answer to my question has already been posted but as I'm new to the forum I couldn't find it.
I've been getting bombarded with "No caller id" calls over the past couple of days and there's nothing I can do to stop these calls. I'm getting them all times of the day n night. In excess of 50 calls through the day, majority through the night. I have an iPhone but that only thing I can block with that is certain numbers but there isn't a number linked with no caller id.
I have been told some networks provide the facility of permanently blocking out these calls.
