There can be several reasons for this.

  1. If you have a new ChargeTag/Pass, it could be that it has not been activated. In this case, you must contact your carrier to activate the card.
  2. If you have activated your charge tag/charge card the same day, it may still be unknown to our Roaming partners.
    We advise the charging tag holder to wait 24 hours after activating the ChargeTag/Pass before it can be charged with our Roaming partners.
  3. Your Provider does not have a contract with Robo Charge / Robo Charge partners. Even though we accept cards from most Roaming partners, this may be the case.
    Contact your carrier to make sure your card is valid on the Robo Charge network.
