T-Mobile has stopped connecting its customers when they call someone using Truphone, saying the VoIP operator is overcharging for interconnection.
Instead, T-Mobile customers get a recorded announcement saying they must have misdialed.
It’s working perfectly fine for me. When I called SMS Text News reader Dan, a Truphone user, just a moment ago (that’s 7pm London time) the call was diverted nicely (he wasn’t in a WiFi area) and I was able to talk to him fine.
Before putting the call through, I got a recorded message letting me know that the call wasn’t part of my inclusive minutes.
