Good experience no major problems with OneSim. But company may need to consider other modes of delivery during a holiday season. If my plans have not of changed for my trip I would not have received the card in time, therefore I would have lost money ,but the customer service is good at least the ones I have had communication so far

SMS service is invaluable for expats. Pricing options & plans are presented somewhat confusingly on website.

I paid 79.90USD for their 2-step verification sms number. The number worked and I did receive the sms code sent by PayPal but then PayPal suspended the account permanently saying the number used when opening the account is fraudulent&stolen. Do not use their service if you are looking to get a US Number to open a PayPal account and for receiving 2-step verification SMS codes.
