I have only had my Lebara SIM for a few months. I visited Spain last month and I had no data roaming. I have checked my data settings, which were OK. I have now visited Spain again and still no data roaming. My wife has exactly the same Lebara SIM deal as me and she has no problems. I have to keep asking her to turn on her WiFi Hot Spot for me to get internet connection. Any suggestions to rectify this problem?
