Hi. I started to use World SIM only for phone, and now I started also with data transfer. Was some problem with settings at the very beginning, but with the help from World SIM help we fixed everything. Thank you NANCY. You help was very professional.
I use worldSIM almost 5 years, still on going. And never have any problems during my trip where ever I go.
Easy to buy, easy to top up and a helpful assistance (Rose)
Well done WorldSIM and Rose
I couldn't make an important international call in central america. Nancy helped me quickly and professionally. I'm happy with the service that she gave me.
Excellent services from world sim. Wonderful online help from NANCY. If the whole world services to world citizens, the whole world would be a wonderful place to live. Please keep it up. I do appreciate your services.
I have ordered World Sim with the help from NANCY that has guided me and I have not gotten the sim up to now, it has taken all my time from beginning of December and nothing has happened. They are full of lies
WorldSIM have the best rates, smooth and easy, great customer service from Nancy!
Defiantly recommended.
Verry professional and quick assistance via the web application. Had issues with payment being accepted by their system, which were quickly and efficiently address by the customer service. Recommended!
I know WorldSim for almost 7 Years. Im based in USA and by far this is the best sim card option you can purchase when you want to go overseas. Pretty much you get GSM coverage worldwide at the best roaming rates. They also have a excellent customer service, i guess they never sleep lol. Overtime i called or chatted with them they were available to assist. I guess they have so much customers worldwide and they got to accommodate everyones timing. I recently bough there new Sim card so i can use my iPhone, the old sim was not compatible. So got on their chat system and ROSE asset me quickly to activate and switch my balance from old sim to the new one.
Overall I'm happy with their service. Hope you can experience the same way :)
I had many questions, which ANNIE answered promptly and with patience. I appreciate her assistance and look forward to the benefits of using my WorldSIM card.
This is REAL. When i saw the recommendation on youtube, i thought it is fake. But it works! And NANCY, the operator, has been dealing with me for over an hour since i can't use the card properly. I called her to setup the card. Then, she has been working through all the steps on phone and on the website with chat. Like when i hand up with her on phone. I tried to buy the data bundle online, and i chat with her on the website since i have few questions. Then, she directly give me a call and said she can give me a discount. I didn't even say anything but she already give me the promotion code! Also, my girlfriend from UK cannot call my number. And end up she told us the format of the phone call is wrong, thats why it doesnt go through. But she is answering the question for me over an hour... what else i can say? She is AWESOME!
Nancy was very helpful and answeres all of my questions regarding the specifics or worldsim. I expect this will improve my travel communication experience
After ive done the order, the website said that there is a processing problem. Ive dealt with the chat support. His name was Daniel, he solved all my problems. It took a while but everything went well.
I purchased two SIMs for use in Italy. One "worked", but not as advertised: text messages could not be forwarded. The other never worked at all. I had to bail and buy much more expensive service from AT&T.
I never used the SIMs. I contacted them twice for a refund and received no response. I am in the process of contesting the purchase through my credit card company.
Daniel helped me to get my sim working again, his instructions were easy to follow, and was very polite. Will continue to use world sim as travel quite a lot to different countries.
I purchased the dual-sim smartphone Sync5z from WorldSIM, as they advertised it as a 3G band phone. Unfortunately, they lied, the phone is only capable of discovering a 2G provider, and I tested and re-tested two phones for a couple of weeks in order to conclude that. The worst was that they never acknowledged it, they blamed me for not being technically savvy enough, and they refused to replace or refund. I somehow managed to limit the damage by appealing to PayPal, who were really helpful. I had to warn everybody: they are still selling this and they still claim that the phone supports 3G!
Hello Dor,
It seems you are unable to properly configure the settings to use the 3G services. The Sync5Z from WorldSIM is 100% 3G enabled dual SIM phone. Please follow the link below to confirm the same:
https://www.worldsim.com/sync-5z-stk-3g-dual-sim-android-phone#technical_specs
Please reach out to us on LIVE Chat (available 24/7) to immediately configure your phone in the correct manner.
We hope you give us another chance to resolve your matter amicably.
Best,

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

Hi Bryan,
We humbly request you to never share your number in any public forum. If you need to highlight any number only share a partial number in the future to highlight your grievance. For example 4474XXXXX.
We would also like to bring to your kind attention that after using any services from any of our SIM, the company policy makes it void for a future refund claim. Our servers clearly show that you have used both these numbers over an extended period of time.We have checked and both numbers are working fine. The last usage details are as follow:
44745237xxxx: Last usage in Italy on 01-Oct-18 12:29:08.11 UTC
44745228xxxx: Last usage in Italy on 01-Oct-18 12:27:11.28 UTC
On a parting note, we would like to inform you that no Operator provides text forwarding facility. This is applicable not only for WorldSIM but also for any contemporary mobile operator.
If you are still unsatisfied with our response, please reach out to us at [email protected]
Hoping to hear from you soon,
WorldSIM Support
