Category : Technologies, Wireless M2M

What is dual sim card router?

Router normally use one sim card for dialup. However, there is another type router use one more sim card. The most is two sim card.


Why need two sim card?

Cellular network sometimes is unstable. So with one sim, the network connection may be disconnected.


Two sim card gets two types also.

1)  Dual sim card with single module modem inside. Two sim can backup each other. One sim fails, the other sim will dialup. It cost some time to switch from the failed sim card to the working sim card.

2) Dual sim card with dual module modem inside. Two sim can work together. Also two sim card can backup each other.  The card switch time is very limited, which means the switching is faster than dual sim single module type.
There is another import feature that the dual sim card dual module can bind the bandwidth. With a VPN server taking binding feature, the two VPN turnel will increase the data speed up to 1.8 times, which is very useful for low data speed areas.
