The ordering process was easy & the customer service people emailed me back quickly with a question. The enclosed info with my SIM card was easy to understand & can be put in my wallet for quick reference .

Easy online ordering. Received my SIM card within a few days. Looking forward to using the passport SIM card during my 10 week study in Japan. Nice to know customer service is available 24/7.
