Hi Rich,
First of all, welcome to the eForum.
It sounds as though the nice Lady over the phone advised you to perform a Manual Search for the network. As I notice you have a Sony Ericsson C905 (Good choice by the way), I have provided you a step by step guide of how to do this again:
Press "Menu"
Scroll to
Settings, press "Select"
Scroll left or right to
Connectivity
Scroll to
Mobile networks, press "Select"
Scroll to
Select network, press "Select"
Select any network other than Vodafone
Once this has been done and it returns to your main screen with no reception, repeat the procedure and on the second time, Select Vodafone.
Once this has been done this will update your network on your BB modem SIM. In all honesty though, you should not have to do this on a regular basis so we might need to look at this closer for you. if the continued dropping of the network continues, we might need to look at replacing the SIM or sending the BB modem away for
repair.
As you have go no connection issues with your handset, I very much doubt that it is the network in your local area so i think we can rule that possibility already and the fact that you travel frequently should not make any difference at all to be honest. As you do travel abraod, you might want to check out our new
Going abroad Summer promotion as this will save you huge amounts when taking your mobile handset abroad.
Let us know how you go on with that and we will do all we can to assist you.
Many thanks
