Vehicle Types
TK103-A is single-SIM. TK103-2B is dual-SIM · auto-switches between two SIM cards for redundancy. Useful for cross-border (Orange SN + Mali SIM) or backup if one carrier fails. Otherwise identical hardware.
Yes · standard GPS103 protocol. Send SMS adminip,<password>,<ip>,<port> (Traxelio onboarding ships the exact string). Device reports to Traxelio without firmware change.
Honestly, no. It's the OG entry-level tracker, still functional, but the protocol is fragile and security is weak. For new installs, use GT06N (Concox) or SinoTrack ST-901 instead. Keep TK103 if it's already installed.
