Some of our customers are assigned phone numbers that were previously assigned to somebody else. We do everything we can to ensure that a “new” number is given to our customers, but from time to time these numbers are still in people’s old address books.
Unfortunately there’s not much we can do to block unwanted calls. If you’re receiving telemarketing calls, you can register your Roam number with the National Do Not Call Registry. If you have a smartphone, you can install an app that blocks and manages calls for you – try iBlacklist for iOS or Call Control for Android.
