4G and/or 5G support on TomTom Bridge Terminal devices

Hi there,

we´re from germany and we´ve sold round about 50 TomTom Bridge Terminal devices to our customers. They use the devices for disposal logistics.
All our customers are located in germany aswell.
One of our customers asked, if the TomTom devices are supporting 4G and/or 5G Internet connection, because of the fact, that 3G will be deactivated in germany in may thios year (2021). Is there any possibility threw firmware updates or something similar to get these devices connected by 4G and/or 5G?
Thanks in advance

Tim
