如果你的USB Modem能在MikroTik的OS认可，那么你可以通过OTG Micro-B plug to Standard-A receptacle，再加上适当配置，那么你的USB 3G在routerboadrd就可以上网。

然后插上我的modem在RB2011UAS-2HnD-IN，只能做到
  1. [admin@MikroTik] /system resource usb> print
  2. # DEVICE VENDOR                   NAME                  SPEED

  4. 1 1:6    HUAWEI Technology        HUAWEI Mobile         480 Mbps

不能再下一步：

    Suck at the port. Mikrotik cannot recognize the huawei modem.

The given link is broken

Do C-hing remember how to solve the problem?
作者: 角色    時間: 2013-10-21 19:33

I know whether the problem came from the Modem that I used or I did not know how to make it work.
作者: Qnewbie    時間: 2013-10-21 23:15

Seeking help from Mikrotik support as the modem is on the hardware compatible list.
作者: Qnewbie    時間: 2013-10-22 05:27

Finally got it work:
1. Power-off mikrotik's router.
2. Plug in USB modem.
3. Power on.

Bingo!

Did you insert any SiM card into the USB modem? What kind of modem that you used?
作者: Qnewbie    時間: 2013-10-22 19:39

Yes, SIM card is inserted.

Huawei E173.
作者: 角色    時間: 2013-10-22 20:27

Were you able to connect the Internet via the modem?

My E1550 modem is also able to give the same results as Qnewbie did

现在modem可以用console连上internet，但是在其他etherX不能上网。
作者: 角色    時間: 2013-10-26 17:01

Now I am able to use the 3G modem to connect internet and write this message. The most important issue to add a router from the 3G modem to the current network by
  1. /ip firewall nat> add chain=srcnat action=masquerade to-address                                                                             es=0.0.0.0 out-interface=ppp-out1

After adding, I moved the above rules to a suitable line.
作者: 角色    時間: 2013-10-26 17:06

For completeness, I included all the rules in my RB for your interest as follows:
  1. [admin@MikroTik] > /ip firewall nat
  2. [admin@MikroTik] /ip firewall nat> add chain=srcnat action=masquerade to-address                                                                             es=0.0.0.0 out-interface=ppp-out1

Maybe you forget the NAT rule:
  1. /ip firewall nat
  2. add chain=srcnat action=masquerade out-interface=ppp-out1
複製代碼
If it doesn't work after adding the nat rule. Check add-default-route option
  1. /interface ppp-client print
複製代碼
set add-default-route=yes if not.

Thanks!

Now I am able to access the Internet via my Huawei E1550 3G modem which was a gift when I renewed the PCCW broadband contract.
作者: Qnewbie    時間: 2013-10-26 19:09

You might need watchdog for your 3G connection too:
http://forum.mikrotik.com/viewtopic.php?f=9&t=69807

I set the 3G modem as failover internet connection and use dial-on-demand but in your case you might need the watchdog.
作者: 角色    時間: 2013-10-26 19:17

Thanks you for your advice.

By the way, what the lowest and best offer of the data plan in your area?
作者: Qnewbie    時間: 2013-10-26 20:28

I have been using mobile phone+surf(speed<1Mb/s) plan(~HK$70) per month for more than one year now.

There was a free data plan(1G/month), which I missed the promotion.
作者: 角色    時間: 2013-10-26 20:59

The plan is very good and not expansive. How comes the mobile phone charge is so high?With the low price data plan, you could make and receive voip calls via the data plan, right?
作者: Qnewbie    時間: 2013-10-26 21:24

Yes, I am using its data plan to make calls.
作者: 角色    時間: 2013-10-26 21:30

The major issue using data plan to make phone calls is the delay! However it will be much cheaper then ordinary mobile operators.
作者: 角色    時間: 2013-10-26 21:46

When the same data card was moved to another 3G modem which is specifically used for China Union network, I was not able to access the broadband internet.
