Prefix Phone

Sound familiar?

Moments every prefix user knows

Will this call be discounted? I'm never quite sure.

A yellow mark tells you before you call. The mark turns yellow when the number qualifies for the discount. Tap it to see exactly what will be dialed.

I called a shop from Google Maps, and didn't get the discount.

Calls from other apps get the prefix too. That includes calls from Google Maps, restaurant apps and the browser.

My history is full of prefixes, and I can't tell who called.

History keeps the original number and name. Calls made with a prefix get a yellow mark, so you can see which ones were discounted.

An unknown number is calling. Answering is free — but should I?

Get clues while it's still ringing. If the number belongs to a listed business, you'll see its name. For any other number, Google results appear right on the call screen. Decide on the spot instead of paying to call back.

I called a work contact from my personal SIM.

Each contact is called from their usual SIM. Contacts show each person's SIM, and the call goes out with that SIM's prefix. A SIM without a prefix works just like a regular phone.
