Sim did not work in Mexico - despite trying on three different handsets. I ended up buying a local Telcel sim which worked fine. Currently requesting a full refund which I hope to receive,
Daniel, was my rep. And spent a lot time with me by answering the questions I needed answered concerning a portable hotspot and updating my Int'l world sim card. Daniel was very processional and knowledgeable. Thank you Daniel
So following my complaints, a SIM replacement was mailed and i got a few apology messages (and some snippy messages which implied I was at fault for their delay in resolving the situation) - The customer service is overall a bit better. No reviews yet for the product... we will have to wait for that!
I have been asking for a solution from WorldSIM since June 11.
I have now sent them the receipt of my purchase 8 times. I wanted a replacement sim card since the one i bought the first time is defective. I have changed my mind... I doubt they have a real service that works properly since you cant even deal with a defective sim card.
I have really had enough of WorldSIM - for future customers, I lost USD 30 buying from them... don't bother falling for this scam!
Also the guy hung up on me twice today when I called once more to ask for a resolution.
False advertising - make sure you read the fine print. The International SIM claims to come with a free UK and Free US phone number. You get a UK phone number and if you can figure out how to get one, you can get a US phone number that expires every 60 days. Then, when people text you on your US phone number, your reply comes through on the UK number so if they hit reply, they end up getting charged for international texting. NOT COOL!

I'm sure they won't be "doing business" for very much longer. I am pursuing legal action...

Excellent service from Allen! Allen answered all my queries and provided me with interesting information that would profit me further.
This is by far the worst roaming/SIM card experience ever. The customer service in India is huge disappointment. They have no clue of what they are doing and Mike (their manager) is the most irritating person you can talk to. At the end of the whole thing they definitely won... as they had my money and I ended up buying a SIM Card directly from AT&T.

I bought a mobile hotspot and data card from them. I should have just flushed the money down the toilet. Neither worked. It ruined my daughter's vacation. Ther customer service is a very bad joke. Trust me, the good reviews here are paid for. I only give one star because they don't allow negative numbers.

My data SIM has never worked and I've tried it in 5 countries now over the past year. I've emailed the support centre so many times, and I just keep getting asked the same questions over and over. They tell me they aren't getting any tracking on the SIM - that's because I'm home and not using it but getting that message across is impossible. I've asked for a refund of my account balance FOUR times now and no progress - just the same questions repeated over and over. Waste of time and money. When I was in Italy I became ill and needed to use wifi - it wouldn't work - and I get no response to this. Stay away from this company and their SIMs, they are useless. The small amount of time it did work, it cost an arm and a leg anyway.

DO NOT buy these cards. You will have so many issues with them. The customer service is a call center in India where they barely speak English. You will have to wait on hold for at least 30 minutes a call and they don't even address the issue half the time. I lost a lot of money with these cards and spent hours speaking to reps who did not even know their own product and just wasted my time.
Hello Hal K.,
We are deeply sorry that you had to wait for 30 minutes to speak to our customer care representative. We would like inform you that we don't have any waiting times for receiving a customer's call. Your call is extremely important to us and it is treated as a top priority.
In the most extreme cases such as technical issues (Servers being down) or a huge amount of calls being received at once, the customer sometimes has to be on waiting. Unfortunately you were one such customer.
Hope you provide us another opportunity to serve you. Have a great day!
Many Thanks,
WorldSIM Support
It's not very expensive for the amount of data and minutes you get. The service is also superbly good! They stay with you until you are 100% happy
Don't believe what you see on their website, WorldSIM are practically lying in how deceptive their prices are. It seems like a great deal but the realty is exactly the opposite. I paid for a SIM card, thinking I would get discounted mobile service overseas but I ended up paying MUCH more for less. Here are three surprises I encountered, hopefully this review will spare you the experience.
1) In Indonesia, only one service is available and my phone tries to constantly connect to it. Following WorldSIM advice actually connects me to it automatically. But instead of the < $0.50 USD per minute advertised rate to call the US, it costs me OVER $5.00 USD, more than 10x the adviertised price.
2) Despite notices everywhere highlighting free incoming calls, they actually charge me $0.17 USD per minute. When confronted, they tell me free calls only apply if someone calls your UK number. This is not mentioned on their website, and is useless to me since I'm based in the US.
3) My phone receives texts but cannot send them. When confronted, they tell me the WorldSIM system is not compatible with Verizon, the US's largest carrier.
I will NEVER use WorldSIM again and feel they owe me money for how deceptive their website is. After spending about $80 on the SIM card and service credit, I'm walking away--better than spending more money for almost nothing.
Dear Josh N.
We hope everything is clear as discussed via email. In case if still any issue, please let us know.
Thanks,

The sim is working quite well as promised.
The best part is the customer service. I had some issue with call connectivity in another country and had to use the online chat to get it fixed. Annie helped me to sort out the issue. I was quite impressed with her service. She was able to troubleshoot the issue quickly. Keep up the good work.
The customer service I received from World Sim is excellent My transaction was completed quickly and the comer service reps are very polite and knowlegable
I bought their sim card for data and voice, it works perfectly in my country. Jonathan was also a good customer service; he answered all my questions and even gave me a discount code to use on my purchase. Great customer service!
Great Service, prompt and courteous staff - Cathy was good handling my issues. Please keep it up. I would recommend WorldSIM to my friends
Matt was very patient and attentive. Thank for you making me choose world sim. All this minor and serious issues I had with the sim was easily sorted by Matt. I hope to keep doing my business with world sim.

Answer: To set up data, I believe you require to set the APN as mobiledata. And their return is around 2 weeks from the day you receive the product.
Answer: THey never answer and if they answer they just say we will solve your problem and they never do. Stay away from world sim card. They are cheeting. 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. Stay away and try to find other sim cards for calling. Travelsim, gocard, gosim, nowroming and others. STAY AWay people from WORLDSIM card
