User Reviews

Most reviews praise Block Unknown Callers for effectively blocking spam and unknown calls, no ads, and ease of use. However, recurring issues include blocking not functioning in the background, intermittent failures after updates, and requests for better dual-SIM control. A few users report that updates break blocking or require manual app interaction to function. Addressing background reliability, update stability, and SIM-specific controls would better meet user expectations.

Pros

Blocks spam/unknown calls effectively
Works as described and does what the description says
Ad-free (no ads)
Easy to use with a simple interface
Reduces telemarketing/spam calls for many users

Cons

Not blocking in the background consistently / intermittent blocking
Blocking stops after app updates or crashes
Some users need to manually open the app for it to block (unclear blocking activation)
Limited or unclear dual-SIM support / desire to choose which SIM is affected
Occasional reliability issues or bugs reported after updates

Recent reviews

Because I receive Medicare, I have been deluged for 3 months of calls from the same area code as exchange as mine. There's no way to talk to anybody to remind them that I'm on the do not call list. This app stopped it all! I've had it for about a week and a half and it has been so peaceful and wonderful. and this isn't one of those that says it's free but, it really means for a trial, and you've got to give them your credit card information. This is absolutely free!
