Test OTP delivery on a real handset

Test one-time passcode SMS on real numbers. See whether the code arrived, whether the sender ID changed, and which vendor delivered it.

See whether a one-time code reached the handset.

The problem

A one-time code that arrives late, from the wrong sender, or not at all looks like your product failed. The supplier's delivery report can say delivered when the handset never got the code.

What to test

Send an OTP-style message — the ready-made one-time passcode is in the test form — to real numbers in the countries you serve, on each vendor you use. Check the sender ID the handset saw, whether the text changed, and how long the delivery report took.

The result

You see whether the code would have reached a real handset, and which vendor did it.
