Outstanding service and help line is always there to get you out of the mire. The descriptions of the products sometimes tend to gloss over the details, but this is also understandable on one page. Recommended
Awesome help from the online support. I knew nothing about the product and in minutes they helped me find any information i wanted. Especially a guy named Daniel was very friendly and useful! I would definitely recommend this company to friends and family!
Very prompt and professional reply. Quick on the answers throughout the conversation. Great user experience. Highly recommended. I was up and running in less than 2 minutes! Keep up the great work.

World Sim to me happens to be the best because their staffs especially the online assistance platform are unique group of people when it comes to resolving issues both technical and network issues. Shawn was very helpful too
I was just looking over things for an upcoming trip. Didn't plan on purchasing any data bundle because my trip is not for another few weeks. I saw that a chat popped up and was greeted by Nancy. She was very helpful and let me know if I got the data bundle now, that I could activate at later date. She even gave me a discount code... that was a bonus... thanks Nancy.
We have used the WorldSim on holiday in Thailand without any issued. It was a live saver as a holiday must when travelling.
Rose has been great. I was having a bit of back and forth trying to understand a charge on a company SIM being used by a colleague and Rose cleared up my query so easily.
Thanks Rose!
I have been using worldsim for a while now, and I love it, very easy to stay in touch with family and friends on the road. I recommend it.
Their simcards work as advertised and if you have any problem at all, their customer services is just plain awesome. They will work with you till the problem has been solved, like Daniel just did. Great job.
As such Matt was quick and hepful, I was told by all representatives that I would be given atleast $25 talktime but ended up giving hardly $10. Very sad.
When I am shopping around international SIM and coming to the WorldSIM website, I chatted with Annie, she helped my for the information of Terms of Service of my purchased international SIM. I need to use the SIM at least once a year to keep my number and keep my credit. I am in US and get additional US number. The direct calling feature is important for my alarm system out going voice message (call back SIM does not work for alarm system). I will say that WorldSIM provides better Terms of Service then some of other SIM vendors. I am considering to buy another one for my car GPS tracker.
My World SIM arrived today. It does work and I do have some credit. But there is no customer service option that works. Just nothing. I am supposed to be able to call free by dialing 190 or 154 from my handset. Neither of these work. The UK customer service number on their website and on e-mails is *******2557. This is not valid number, if I ring it it just cuts out. Their instant chat is just a useless bot, no help at all. I filled in an enquiry form saying that *******2557 was not a valid number and I got an instant reply telling me to ring *******2557! I sent a FB message saying I could not get in contact and got an instance response telling me to use instant chat or ring *******2557. All in all terrible, utterly terible - it is going in the bin. Do not be fooled like me.

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
