Unifi sim card can't use on GPS tracker

Hi,

Just found my unifi prepaid SIM card can't use on my GPS tracker after I use it for a few years. However, there is no problem to use on mobile phone. May I know is there any problem on the SIM card ?

Thank you

No. I use 4G SIM card to test on GPS tracker & it's work.
