One application area of Teltonika Telematics‘ prepaid SIM and eSIM connectivity solution, which we have already featured, is vehicle tracking. Many transport businesses are regulated by governments worldwide. For example, lorries must be equipped with digital tachographs so that the data is sent according to a schedule; E-TOLL, modern toll collection solutions, are governed and electronically charged. Reporting is being digitised and made mandatory at the government level. Given this, measures should be put in place to facilitate the ease of data transfer and ensure its stability.



As most transport and logistics companies are controlled by public authorities, fleet owners are required to submit digital tachograph charts regularly based on strict rules. Failure to submit data on time will inevitably result in heavy fines.

In the case of E-TOLL, a GPS tracker sends information on the location of a vehicle, the data is processed in the payment collection system, and a local National Revenue Administration automatically taxes the vehicle or fleet owners respectively.

But what happens if the data is used up or the mobile network SIM card expires? Of course, the tracking device will be disconnected from the GSM network and no data will be sent at all.

Fortunately, Teltonika Telematics has a practical solution to help corporate fleets avoid such needless fines and ensure that the SIM cards of GPS trackers are always connected to the GSM network.



Every single Teltonika vehicle GPS tracker has a placeholder for a plastic (regular) SIM card or a possibility to install an eSIM module. The SIM card or eSIM is part of the Teltonika Global Connectivity Solution and is used to connect to mobile networks, and the GPS device will be able to send and receive data to and from locations covered by the data plan.

For example, the Teltonika Global Plan currently allows you to prevent roaming costs in 110 countries around the world and uses the same amount of data anywhere. But the fact is, any data plan has a limited number of megabytes, and if they are used up, a GPS tracker loses an access to the mobile network.

How it works – to keep SIM cards up and running continuously without physical and manual interference, we offer the convenient and practical Auto Top-Up feature. As the name implies, when properly set up, this function automatically renews the same data plan under the same conditions when the remaining amount of data has been used up to a specified limit. Thanks to it, fleet managers and business owners will not run into trouble if a SIM card plan data is nearly used up, or expiration term is around the corner but a person in charge has missed all the notifications, off duty, or simply forgot to top up the plan timely.

Please note, the mobile top-ups themselves need to be purchased in advance, so that they can automatically top up SIM cards of GPS trackers mounted on vehicles. To get ready to use the Auto Top-Up feature, please contact your Teltonika Sales Manager at your convenience. Handily, any number of top-ups can be purchased in advance, so fleets of any size will not be short of connectivity options.

With the SIM card management IoT Platform, you can set up specific SIM cards to be topped up, choose notification rules (via email or SMS) when 90% or any other percentage of data is used up, or inform a person in charge that the last top-up has been depleted and there are no more of them left. As a result, there is no point to monitor the amount of data or the expiry date anymore, as automatic top-ups reduce the need for manual maintenance of the SIM cards, and fleet GPS trackers will always remain connected to the GSM network with no service interruptions.

To sum up, the Auto Top-Up feature provides an effective way to automate the top-up procedure, stay continuously connected online, avoid data flow interruptions and/or unwanted penalties when a SIM card is used up or expires. Get as many mobile top-ups as your business needs, set the rules with an IoT Platform, never be disconnected again and keep your reputation intact!
