I purchased 5 SIM cards to be used for a trip to Europe for $120. They arrived on 6/20. None of them worked; when i put them into my phones, they all caused the phones to say No SIM card installed. It took several days to hear back from tech support and they could not resolve the problem. Since I was leaving on my trip a few days later, I did not have the time to try and get them to work and/or get replacements from them given their lack of responsiveness. I also did not trust the company or the cards assuming they did end up working, so I asked for a refund. I have been trying ever since to get a refund.
The company WILL NOT HONOR THEIR WARRANTY. They are refusing to give me a refund, even though it was requested within their stated 14 day window. Their warranty also is for 6 months against defective product, and they refuse to refund me based on that either. They keep telling me it is unlikely that none of the cards work, even though I tried troubleshooting them with their tech support before I went on my trip. The form to submit a refund request on their website does not work - it tells me that the case number is invalid, even though it is the same one they are using in their email correspondence. They tell me I should use their live chat so they can troubleshoot, but there is no way to access the live chat on their website, and they won't tell me how to access it.
This is a HORRIBLE COMPANY that thinks very little of their customers. They do not honor their warranty and do not stand behind their product. I am now out $120 thanks to them. I ended up purchasing my sim cards from OneSIM and they worked fine (with excellent customer service). If I could leave 0 stars I would.
UPDATE - since this review was posted, WorldSIM responded below. Their response is a complete lie. I am the actual customer and they have NOT issued a refund. They also claim you need unlocked phones. All of my phones are unlocked, otherwise the other SIM cards purchased would not work. This is further proof that the company does not operate honestly; posting lies about a customer is reprehensible.
