STAY AWAY! SIM broken in less than a week! Only way to get it replaced is to pay 30Euro! After less than a week, when I was in USA for work, the SIM got broken. I knew the problem was the SIM as it was sitting in the same phone in which was previously working (just tested before traveling abroad). I got in touch with the support several times. Each time they were trying to put the blame on the phone. If I wanted the SIM replaced I had to pay 30 and it will be shipped within a couple of weeks when I was already back from abroad and had no use anymore.
In a nutshell
1. The support isn't supporting you but just trying to get your money
2. The sim are poor quality and get broken as son as you start using it
A very bad experience
I purchased a WorldSIM for US and canada. It took me really a few second to do the purchase with the help from NANCY that has guided me and informed me about all the question I had. Very professional help!
Online Service was very helpful, was not aware what to choose. The agent give me a good solution. The online Chat Chapp was very Helpful.
Quick and satisfactory reply and I will order more in the future can't wait for my product delivery hope they gonna deliver it soon
The absolute WORST company to get a sim card from. The customer service is an absolute joke and send scripted replies and never answer real questions. They scammed me on phone calls charging $1.22 a minute for a call from the UK to the United States. They told me my US number was considered a "premium" number and that's why the high cost. Well, my premium number is a regular cell number with one of the big carriers here in the US.
And guess what, their crap customer service never got back to me after I informed them the number was a regular US cell number.
You have been warned.

I bought a Rs. 1999 WorldSIM UK card from an agent Shashank Sharma, Delhi India. Shashank and Megan promised me that it will work in UK. The SIM card never worked. I had so much difficulty because of this. I wrote to WorldSIM all I got from them was a lip service. DO NOT BUY FROM WORLDSIM INDIA. All agents in India are fraud scum

I'd like to write regarding to the "Worldsim" online support. Specially to support specialist Daniel. He has helped me very fast and on the highest level.
I purchased a TP Link mobile wifi device and upon their recommendations, purchased a data bundle SIM card to go with the device. This was to be used in Indonesia. The SIM card has a 7 day and 250MB data validity from the time of activation. I couldn't activate it on-line so called them on 14/01/2019 to get it activated. They emailed me to say the problem has been resolved and the SIM was activated for the 18/01/2019 (the day I was arriving overseas). On the 18/01/2019 I inserted the SIM card to the device and it wouldn't connect to the local network. I used my mobile phone to chat with WorldSim customer service. The person got me to try all sorts of things, including using another mobile phone to connect to the local network. It still didn't work. By then I had spent too much money on mobile data chatting to WorldSim and nothing was working. I decided to cut my losses short and accept that it wasn't working and address it when I arrived back in Australia. I am back in Australia and have been communicating for over a week with WorldSim and they just keep making up excuses. They want me to try the SIM card again on the device... well, I am now in Australia and the unused data allowance is now gone as it only had a 7 days validity from the 18/01/2019. They told me the device was not set up correctly but I used the device with another SIM card and it worked. They then said the matter was closed on the 14/01/2019, which was the chat I had with WorldSim to get the SIM card activated prior to me leaving the country. I kept going around in circles and I think this may be their tactic to get customers to give up their quest in getting a refund for a dodgy product. Avoid them like the measles!
Hi Novta,
We pulled up your problem sheet and found that indeed you had run into troubles while using our products. We had repeatedly tried to solve your issue through email and chat support. What you have failed to mention here is the actions we had requested you to perform to work with our mobile WiFi and our data SIM Card. As per our records indicate, we had assisted you in the best of our capacity. Here are some excerpts:
1. On the 18th January, I inserted the SIM on the device (the SIM card was purchased for the TP Link 4G LTE device I bought from you and the SIM card was purchased upon your recommendations). It didn't work.
When you tried, it was not connected to any network. The SIM must be connected to the network to use data. On the chat our representative had asked you to insert the SIM card in any unlocked phone but you said that you will try later. The chat was disconnected by you. Your last reply was "I have to go now. I will just try again later. If I knew it wouldn’t work with the TP link, I wouldn’t have bought it. Thanks anyway". After that we didn't get any request from you.
2. By then I had already spend close to $50 on costs and lost time chatting to you and none of your instructions could get the SIM card to work. The device itself was definitely set up correctly as when I inserted a different SIM card, it worked and I ended up using the device with no issue, so the device set up is NOT the problem.
Yes, you are correct. The device was set up correctly but the SIM card was not registered on the network. The SIM must registered on the network to use services.
3. Obviously, it was never activated because I was unable to use it on the 18th January. So you had sold me a faulty SIM card, promised me that it was activated for the 18th January, and when I got overseas, I wasn't able to use that SIM card. There is no need to send me instructions on how to set it up on the device because the SIM card is no longer valid as it was only valid for 7 days (supposedly from the 18th January) so I cannot use it. The credits I had purchased is now gone unused. Hence, I am seeking a refund for the full costs. (GBP25)
The SIM card is not faulty. If it is faulty, we will provide you a new SIM card without any charge. It's our responsibility. But before that, you need to follow the instruction. Here, we would like to bring it to your kind attention that, we do not have any monthly charges and contract so you can use this SIM in future as well. We have added $37.50 to your SIM.
As you can see, our instructions were not followed properly. Kindly, suggest a method we can help you in any other way. We promise you will have a amicable solution after you contact us.
Hoping to hear from you in earnest,
WorldSIM Support

They just want you to buy the card and then no support. I have called and emailed and open case for 10 times.( i have 10mails) and their answer was " please test again and if there is a problem we are happy to assist you" thats it. No solution, no nothing. I cannot call UK numbers 0044. I have sent 10 emails, I lost money from my job because of the time tryting to connect with them and 2 weeks later, today the answer I received for my 10th email was Dear customer, Please re-test and share latest couple of examples if failed again to investigate this issue further. We will be delighted to assist you with any further queries that you may have. What do you think? It is worth giving their money to them? Definately not.
