There are a few different causes depending on whether the name or the number itself is wrong.
Name is wrong or not showing — it may just need time
Caller ID name (CNAM) is stored in a carrier database that can take 24–72 hours to update after a new activation or number port. This resolves automatically — no action needed within this window.
Check whether you're calling from the right line
On dual-SIM devices, calls may be going out on a different SIM than you expect.
iPhone: Settings → Cellular → Default Voice Line
Android: Settings → Network & internet → Mobile network → select the correct SIM for calls
Third-party calling apps show different caller ID
WhatsApp, Google Voice, FaceTime, and other VoIP apps use their own caller ID — not your mobile number. This is expected and cannot be changed through your mobile plan settings.
