Very poor
Very poor. Onesimcard is supposed to be the "travellers' SIM", but when I filled in their purchase form I had 3 problems: 1. they didn't accept a non-US mobile phone number as my home mobile. So I had to invent a fake phone number just to progress my purchase. 2. they refused to accept a non-US post code - do travellers only come from the US? 3. when I contacted the "Help" chat, the guy got annoyed, and wrote "why is your delivery address different from your home address?" What?? Does the "travellers" SIM company not understand the nature of "travelling"? (ie: being somewhere other than home). Naturally did not buy the SIM, and judging from these other reviews, I had a lucky escape! But I did waste an hour of my precious time because of their incompetence, so they get the review.
