The steps to select and lock LTE bands on Teltonika devices are as follows:
The steps to select and lock LTE bands on Teltonika devices are as follows:
#Open device‘s WebUI and go to '''Network''' -> '''Mobile''' -> '''General'''.
#Open device‘s WebUI and go to '''Network''' → '''Mobile''' → '''General'''.
#If necessary, select the SIM card you want to apply band lock to.
#If necessary, select the SIM card you want to apply band lock to.
#Under the SIM card settings section, select Service mode '''4G (LTE) only''', otherwise, in case of no LTE signal and depending on availability, the router will switch to 3G or 2G service.

You can check if the router established connectivity through your selected band by going to '''Status''' -> '''Network''' -> '''Mobile'''. In the mobile information table provided, there is a line called '''Connected band'''. It shows the band the device is currently connected to, which should also be the band that was chosen manually.

In this case, connection details shown in '''Status''' -> '''Network''' -> '''Mobile''' section also display a carrier aggregation status as '''Dual''', indicating that modem has established connectivity between two different frequencies.
