Call Ranger: Mass Call Blocker

Block entire area codes, country codes, or any phone number range with Call Ranger!

Instead of blocking spam numbers one by one, create a single rule that covers a whole range. Choose how many of the last digits to replace with X, and every matching call and message is blocked. One rule can cover up to 10 billion numbers!

GLOBAL EXAMPLES:
• US: "+1 415 XXX XXXX" → blocks +1 415 000 0000 to +1 415 999 9999
• China: "+86 10 XXXX XXXX" → blocks +86 10 0000 0000 to +86 10 9999 9999
• Japan: "+81 3 XXXX XXXX" → blocks +81 3 0000 0000 to +81 3 9999 9999
• South Korea: "+82 70 XXXX XXXX" → blocks +82 70 0000 0000 to +82 70 9999 9999
