You'll realize you made a horrible mistake once you load the nonrefundable account with money and begin to sort through the various plans which, at the time I did this admittedly a couple years ago, was a nightmare. I would suggest buying SIM cards when you land - it's easy, cheaper and you know you'll get it right. I suggested to OneSim that they let customers submit a travel schedule (my son went through like 10 countries) and then they could develop a plan for appropriate SIM cards. But, as you'll find out if you purchase this godawful service, you can spend hours getting through, talking to customer service, trying to parse plans and really still have a big question mark. In the end, OneSIM kept my $290 remaining dollars in my account and I had no choice but to part ways - then I found out using them wasn't even necessary.

Hello Troy, We are sorry to hear about your experience with us here at OneSimCard. Many customers use our option instead as we provide coverage in multiple countries without the need to purchase a local SIM card for each country they travel to. In certain countries, you are not even able to purchase a local SIM unless there is proof of residency. For SIM selection, we do have an online tool that allows customers to select the appropriate SIM card based on the country of travel. This can be found here: https://www.onesimcard.com/best-roaming-sim-card-selection/ In regards to plans, the discount data plan options are available and certain plans will cover a wide range of countries but not all. It is important that whatever plan is selected will cover the itinerary. We hope to have your continued business as you indicate that you have some remaining questions as well as a remaining balance. Please send us a quick message to [email protected] and a member of the support team will reach out. Please include your SIM card number and best contact info. Thank you again for the feedback and safe travels, OneSimCard
