If you’re having trouble starting a charging session, don’t worry — most issues can be resolved quickly.
When everything is done correctly, the most common reason a session does not start is a roaming issue between the operator and the charging provider.
Here’s what to try first, followed by a short guide to double-check the basics if needed.
1. Most common cause: Roaming issues
Roaming interruptions occur frequently across public charging networks and are the leading cause of failed session starts.
What to do
Try another charging point at the same location.
If it fails again, go to another nearby station.
If charging still does not start and you want to rule out other causes, follow the steps below.
2. If you’re unsure: Quick guide to check the basics
These steps help confirm that everything is set up correctly.
2.1 Check the connection between your car and the charger
Most stations work reliably, but different chargers require different start sequences.
If you’re not certain which sequence applies, this guide helps clarify it.
2.1.1 Give the charger a moment
Some chargers take a few extra seconds to initialise.
Try waiting about 30 seconds before retrying.
2.1.2 Confirm the correct charging sequence
Not all chargers behave the same. If the wrong order is used, the session may not start.
Check the instructions displayed at the station or try the sequences below.
Option A — Authenticate first, then plug in
(Most common on public AC and many DC chargers)
Open the charging app and select the charger or scan the QR code
Wait for the charger to unlock or become ready
Plug in the cable
Charging begins
Option B — Plug in first, then authenticate
(Common on DC fast chargers with automatic plug detection)
Plug your vehicle into the charger
The charger recognises your vehicle and prepares the connection
Authenticate in the app or via QR
Charging begins
If the session still does not start, continue to the next step.
2.2 Check your payment method
Before each session, Cariqa places a temporary hold (pre-authorization) on your payment method.
If the pre-authorization fails, the session cannot start.
Common reasons
Insufficient funds
Expired or invalid payment method
Bank or provider blocking the transaction
What you can do
Update or replace your payment method
Try again after updating
2.3 Check your network connection
Your phone must have sufficient signal to authenticate a charging session.
