Avoid roaming with Network Manager and HSDPA/3G dongles

Today a friend of mine asked if I knew a way to avoid connection via his HSDPA/3G dongle when in roaming: he uses Italy’s Tre network, and sometimes the connection will fall back to TIM or Vodafone, which he wants to avoid because of increased costs.

I’ve discovered that in GNOME’s Network Manager connection editor you can force a network by inserting the MCC/MNC (Mobile Network Codes), a list of which can be found at http://www.flatbatt.co.uk/Unlocking/Network_codes/network_codes.html

  1. Nice info!
    But i live in Indonesia, and don’t know my provider network codes. So I use umtsmon to force to 3G (UMTS) network.
