I recently returned from a trip to France and Morocco, my first since switching to Ting mobile. LSS, international roaming did not work at all. In every case, my phone (iPhone SE 2022) connected to the local service with LTE or 4G, but all data, calls and texts were blocked, nothing went through.
Extensive emails and calls with support were unable to resolve the problem. I am curious to hear if there are other users who have successfully used international roaming.
