During the purchasing flow, you must provide a contact number for the collection and the delivery in case there is an issue. However, as a general rule, couriers won't call you before the delivery. Not all couriers carry business phones or can call.
The management of incidents with collections or deliveries is carried out from the central office of the transportation company, once the route has been completed, so they usually contact you the following day.
If it’s an international shipment, it’s important that you enter a local phone number, where the shipment is being delivered.
Although roaming in the EU is included in mobile tariffs, transportation companies do not call foreign phones to arrange pick up or delivery, as in most cases their terminals are blocked for this.
You can always check the status of your shipment in your Packlink PRO account.
