Considering this is my job. I am the roaming engineer for Telia in Norway. I welcome the change. Yes we lose revenue, but at the same time, costs for customers are getting out of control. The funny point though is that the costs within EU are already low enough. What needs to be changed is roaming prices in the rest of the world.
It also means we have to work harder with our roaming partners to create new Wholesale discounts. Thing is though, I have read through the new plans. And the fair usage policy is ridiculously complicated, this is where we will have to focus everything and where telcos will win or lose their customer base. For example, of the 30days roaming, if a user is travelling to his home PLMN (home network) in the same day as travelling to visitor PLMN (foreign network) after having visited the VPLMN once in said day already, then it shouldnt count towards the 30day or 90 day tallies. Trying to keep track of this is brutal considering the sheer amount of Norwegians we have driving across the border to Sweden, or heading to Denmark.
BEREC have yet again made the new regulations pretty vague in areas, meaning its almost possible to interpret some scenarios however you want it.
