There's plenty to do in Watch Dogs, and you'll need to finish all the little side missions if you want to get all the trophies or achievements for the game. One of the side missions involves finding 'burner phones', or untraceable, pre-paid cell phones, around the city. There are 8 phones total - after finding 7, you'll be rewarded with the Vespid LE muscle car. After finding them all, you'll get the bronze trophy/15 point achievement Sanity Check. You can find the phones in any particular order.
The burner phone locations will be marked on your map, but only if you have cleared through the ctOS towers in that area. Whether or not you can see them on the map, you'll still be able to pick them up from the start of the game. Remember, you can get these in any order. The story will progress in the same way.
This first phone is not missable - you'll get it in the opening mission called Bottom of the Eighth.
In the Pawnee district, find this phone in the trailer park. It is near the back, left-hand side, by a junked blue car. It's on the roof.
This one is also in the Pawnee area. It is to the north, on the roof of the motel here. Climb up the yellow ladder on the left side of the building and go across the roof to get the phone.
The last phone in the Pawnee district is in a shed behind a restaurant. It's south by the piers. Go through the gate next to the building to reach the shed and grab the phone from a tool box.
The Wards district has only one phone, located in ghetto. You can find it in the courtyard between the apartment buildings, on the third floor of a crumbling building.
This phone is found in The Loop district. It is found under the freeway, where the homeless people live in tents. Look for it on a makeshift bed in a cardboard box shelter.
The last two phones are found in Brandon Docks. This one is found in an industrial building on the vertical side of the island. Go inside and up the stairs to find the phone on top of a desk.
This Brandon Docks phone is in another industrial building, near the bridge between islands. This building has a large security gate that you need to hack to get in. Once inside the building, go upstairs and to the left. Then turn right to find the phone sitting on an old mattress.
