Not happy at all!
Cost me £28 for 20GB of data to cover North America for 14 days. It was OK while in Vancouver, but once we embarked on our cruise ship, it was practically unusable. I do realise that coverage in Alaska is sketchy at the best of times, but onshore in major towns, it was still rubbish. We arrived in one town, and our bus driver told us there was an AT & T mast, so we would have no trouble connecting to the internet. I literally stood next to the mast, but still could get nothing. I contacted Airalo, when I could get a signal, and they asked me to check numerous settings on my phone, all of which were correct. They then asked me to turn on airplane mode for a full five minutes, then after turning it back off, I could not contact Airalo at all. That's £28 I'll never see again. Not happy!
