Come controllo quanti dati mi restano?

Ci allineiamo con la rete ogni 60 secondi e ti mostriamo l'orario, così sai sempre quanto è aggiornato il numero.

Why the app and your phone will never agree

They are counting two different things. Your phone counts every byte since a reset date you chose, including wifi on some builds, and it counts what the radio attempted. We count what the network actually billed, reconciled every 60 seconds. The two are always a little apart and neither is lying. When they disagree, the billed number is the one your balance moves on.

Why we print the timestamp

Because a usage figure with no time on it is a guess presented as a fact. Ours reconciles with the network every 60 seconds and the screen tells you when it last did. If you are on a train through a tunnel, the number can be a few minutes old and you can see that it is, rather than wondering.

When the number moves and you were not using the phone

Background traffic, in almost every case. Four things account for most of it and all four are worth turning off before a trip.

• Automatic photo and video backup over mobile data
• App updates over mobile data
• Mail fetching in the background on a short interval
• OS updates, which will take a gigabyte without asking twice

What we do automatically and what needs you

We reconcile every 60 seconds, show the timestamp, and estimate how many days are left at your own historical rate rather than at an average traveller's. We do not throttle a metered plan at any point, so a slowing connection is never us managing your usage quietly. What needs you is turning off backup over cellular, which is the single biggest cause of a plan emptying in a morning.

The numbers, and where they came from

Most people use 3 to 5 GB on a week long trip without streaming. The days remaining estimate uses your own past trips where we have them, and falls back to that range where we do not. A gigabyte costs $4.89 at the smallest tier and $1.36 a gigabyte at 50 GB, so a mid trip top up is a small decision rather than a large one.

Making a plan last, in order of effect

If the balance is going faster than the trip is, these four changes account for most of the difference, and they are ordered by how much they save.

• Turn off photo and video backup over mobile data. This is the single biggest one and it is not close.
• Turn off app updates over mobile data, and update everything on wifi before you fly.
• Download maps for the city offline before you leave. Navigation itself is small, map tiles are not.
• Set streaming apps to a lower quality over cellular, which most of them offer and none of them default to.
