Go through these steps:

1) is your usb modem supported by ROS?
2) did you plug it in and do you see ppp-out1 interface?
3) did you set the correct data channel and info channel in ppp-out1 properties?
4) did you set correct APN name in properties?
5) last but not least, did you add nat rule?
/ip firewall nat add action=masquerade chain=srcnat disabled=no out-interface=ppp-out1

By ROS he meant Router OS.

You can take a look here for supported hardware: http://wiki.mikrotik.com/wiki/Supported_Hardware

ZTE MF110 works fine.

In case there are other users having problems configuring this modem :

[dark@RB951G] > interface ppp-client print detail
Flags: X - disabled, R - running
 0  R name="ppp-out1" max-mtu=1500 max-mru=1500 mrru=disabled port=usb1 data-channel=2 info-channel=2 apn="internet" pin="" user="" password=""
      profile=default phone="*99#" dial-command="ATDT" modem-init="ATZ;AT+CFUN=1;ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0" null-modem=no dial-on-demand=no
      add-default-route=no use-peer-dns=yes keepalive-timeout=10 allow=pap,chap,mschap1,mschap2

tested on RB951G - ROS 5.22
