Using KT Rwanda Networks' (KTRN) IR.21 document to determine carrier ownership is incorrect for consumer applications. The authoritative source is the Rwanda Utilities Regulatory Authority (RURA) National Numbering Plan, which distinctly allocates these prefixes:
- 250 72 / 73: Airtel Rwanda
- 250 78 / 79: MTN Rwanda
- 250 77: KTRN
By mapping 7[237-9] entirely to KTRN, libphonenumber is currently misidentifying millions of MTN and Airtel users. Please revert this change to align with the official RURA allocations.
