> I missed important business calls when in US. Because they were calling using same area code where my sim card was registered, so I thought it was from the area local to me. I just ignore calls from my prefix. There's literally nobody in my contacts that has the same prefix I have, and I consider it extremely unlikely that any legitimate calls will come from there. 90% of spam calls come from my prefix, and most of the rest come from out of state (different area code entirely). Another way is to just ignore all calls not in your contacts, and use Google voice's voicemail transcription (I think I've read about some way to do this with Twilio or another service, but I might be wrong).
