OsmO users switch on conditional call forwarding so their assistant can catch the calls they miss. Here is how often that actually works, network by network — measured from real setups, not surveyed.

Your carrier matters more than your phone.

On AT&T, 66% of people got call forwarding verified, against 3% on Metro by T-Mobile. Both are small groups (32 and 33 people), so read it as a signal, not a verdict. In India, Airtel (36%) edges out Jio (33%). Struggling? Our step-by-step forwarding guide covers the codes each network expects.

Why forwarding fails

The usual suspects when the code does not stick.

The wrong code for the network. GSM networks use **004*-style codes, while Verizon-family networks use their own *71 and *72 codes.
Dialled from the wrong SIM. On a dual-SIM phone the code must go out on the line that receives your calls.
The plan blocks it. Some prepaid and family plans switch conditional forwarding off until support turns it on.

How this is calculated

Tried: one recorded forwarding attempt per person and date.
Verified: the first inbound proof that forwarding works, within seven days of that attempt. A cohort is counted only after those seven days pass, so late proof has time to arrive.
The trend is a rolling 30-day window. Carrier names come from the phone’s network operator, so a reseller (MVNO) may appear under its own name.
This is OsmO product data, not a census of every phone on a network.

Only aggregate counts leave our database. A carrier stays hidden until at least 30 people have tried forwarding on it. No names, numbers, recordings or transcripts are used.
