Sierra Wireless AirCard 313U

Using with Ting

Reference: https://mycusthelp.net/SIERRAWIRELESS/_cs/AnswerDetail.aspx?aid=44

• First, make sure the SIM card is activated with ting
• Then, find the USB tty device. its usually the 3rd device created after plugging it in. so if you didn't have any ttyUSB* devices, it would be ttyS3 (starts at 1)

sudo screen /dev/ttyUSB3 115200

• To verify modem is responding type ati5. It shows modem IMEI and Firmware

ati5

• set ting APN:

at+cgdcont=1,"IP","wholesale"

That should do it. If you have a network manager running, you should use it to configure the device. Otherwise:

• dhclient <dev>

Other useful commands:

• Turn radio on:

at+cfun=1 

• Turn radio off:

at+cfun=0

To manual connect: at!scact=1,<profile>. e.g:

at!scact=1,1

To manual disconnect: at!scact=0,<profile>. e.g.:

at!scact=0,1

Using with pfSense

To use this device with pfSense:

• Login to pfsense web portal and go to Interfaces -> PPPs
• Click Add and use the following:
  • Link Type: PPP
  • Link Interfaces: /dev/cuaU0.3 (adjust if you have other USB tty devices)
• The rest will depend on your provider, but for Ting I use:
  • Country: United States
  • Provider: T-Mobile
  • Plan: LTS - fast.t-mobile.com
  • Username/Password: leave empty
  • Phone number: *99#
  • APN: wholesale
  • The rest: defaults
• Click Save
• Go to Interfaces -> Assign
• For Available network ports, choose "PPP0(cuaU0.3)" and click Add
• It named mine OPT1
• Click OPT1 to edit it and then use:
  • Enable: [x] (checked)
  • Description: WWAN
  • IPv4 Configuration Type: DHCP
  • IPv6 Configuration Type: DHCP6 (doesn't seem to support IPv6)
• Click Save

To set up as a failover internet access:

• Go to System -> Routing -> Gateway Groups
• Click Add and use the following:
• Group Name: INTERNET
• Gateway Priority:
  • [WWAN_DHCP] [Tier 2] [Interface Address] [Interface WWAN_DHCP Gateway]
  • [WAN_DHCP] [Tier 1] [Interface Address] [Interface WWAN_DHCP Gateway]
  • Trigger Level: Member down
  • The rest: defaults
• Click Save
• Go to System -> Routing -> Gateways and click on WWAN to edit
• Change the monitor IP to something different since the default won't work (I use 8.8.8.8)
• Click Save

You can now test the failover functionality by unplugging your WAN connection and see if your internet access works
