Could you build this?
Partial Android exposes the network country, operator, and technology through telephony APIs, so a basic version is feasible, but iOS does not give apps reliable access to this cellular network information.
What it would actually take: On Android, use TelephonyManager to read the registered network's MCC/MNC and radio technology, mapped to country and operator tables, with a notification on change. An iOS version would need a different approach because the platform restricts this data, so it may not be fully buildable. The hard parts are the platform restrictions, accurate operator/MCC mapping data, and handling edge cases like multi-SIM and roaming detection, which call for mobile telephony knowledge.
