Single SIM suitable for scenarios with good network coverage and stable operator signal; dual SIM suitable for three major scenarios: first is weak signal in remote areas with dual operator backup; second is high reliability requirement scenarios such as power, transportation, finance, automatic switching when single link fails; third is load balancing, dual card bandwidth aggregation. Tespro industrial router dual SIM supports intelligent switching with switching time less than 30 seconds, supporting same operator or different operator backup. Recommendation: single SIM is sufficient for ordinary projects, dual SIM backup is necessary for important projects. With 24 years of industrial communication experience, Tespro dual SIM technology has been verified by tens of thousands of projects, 99.99% uptime is industry benchmark.
