LTAP 是常开Roaming, 過關要VOWIFI不是很方便,所有改了用mode-button, 按一下改那個SIM 連上網,WIFI網路不會斷太久。
開Mode-button:
/system routerboard mode-button set on-event=switchsim
/system routerboard mode-button set enabled=yes
system script switchsim
{
:local simSlot [/system routerboard sim get sim-slot]
:log info "Mode Button press, switch sim-slot current $simSlot"
:if ($simSlot="down") do={
/system routerboard sim set sim-slot=up
:log info "swtich sim position by mode to up"
} else {
/system routerboard sim set sim-slot=down
:log info "swtich sim position by mode to down"
}
在旅途中拿電腦開Winbox,來要改雙卡單待的 SIM比較難。所有改wiki mikrotik "dual sim Script". SIM up(hk) 是香港, SIM down(CN)是中國, 要是沒有連網, SIM UP and SIM down (互換)。
{
# Setup and read current values, switch between "up" SIM slot, and "down" if not connected.
:global simSlot [/system routerboard sim get sim-slot]
:global timeoutLTE 60
:global timeoutConnect 60
