WorldSIM

Worst service ever! DO NOT waste your money! Unresponsive and bad customer service. The global eSIM I purchased before traveling didn’t work in the USA at all! After insisting the offered me a complimentary USA-only eSIM that stopped working after TWO days of usage! Then I had to buy another eSIM card from a different provider, obviously, for… Read more

the rest of my trip outside the USA.

Extremely disappointing and unreliable!

I asked for reimbursement since day 1 contacting you but got no response to that. Felt like a proper scam!

Paid for an item on the 24th December with a 5-7 day delivery time. Haven’t even received tracking yet and no response from customer service. Avoid this company.

Connection Help Excellent – I used the WorldSim Chat line (Annie) to get help in activating a Sim card (it wouldnt activate as it should have). She was terrific, responded quickly and was very patient. I do think the set up process could be more seamless but, once set up, the service works brilliantly and is quite quick. Wonderful! Show details

Customer Service – Very friendly customer service always and very fast at solving problems. Well done to a awesome company. Also love the fact that their chat is available at most times and they are quick to answer. Show details

Quality Service at a resonable Price – WORLLDSIM service has been outstanding as I travel the world. It provides all the connectivity one could use at reasonable prices. It is much more economical than a monthly subscription if you are not a heavy cellular user. Well worth the price to use during your travels. Customer support by Chat or e mail is extremely fast.

- September 19: My SIM stopped working - showed “No service”. Balance check code dialed from calls history that previously worked returned no information - September 20: Needing urgent service and suspecting a low balance, I made a £10 top-up. The service was not restored. - September 20: I contacted customer support. After extensive… Read more

troubleshooting, their agent identified the cause as an "internal issue of local provider" and promised a resolution by their team and follow-up email by the next business day. I received no email update on this. - September 24 - Present: With the line still completely inactive, I requested a refund for the £10 top-up, which was made under the false pretense that balance was the issue. Since then, I have faced daily refusal and have been offered only a "future credit" for a service I cannot use.

In their final response, WorldSIM ignored the documented history and falsely claimed the line was active, using a screenshot of data usage that ended on September 20—the very day I reported the total failure—as proof. This demonstrates their refusal to engage with the facts.

WorldSIM has failed to provide the service I paid for, ignored to admit the technical fault diagnosed earlier by their team, and refuses to refund the mistaken payment.

Purchased a data sim. Didn't work from the start. Contacted World Sim twice and they advised they would fix the problem and send me an email. Its been 6 weeks and nothing. DON'T waste your money or time with these scammers. They are selling a product that they can not provide. They will take your money and run. Unfortunately they don't even… Read more

deserve 1 star. And to top it off I continue to get sales emails from them offering 10% off. And There is no "unsubscribe" option.

Very poor eSIM option for Europe - purchased data and voice eSIM with promise of up to 11Gb in data usage but credit ran out after just over 1Gb. Service also kept dropping out for long periods. Spent hours talking to tech support to no avail - kept being told that advertised data amounts are ‘estimates’ only. Ended up moving to another data-only eSIM that has been much better and seamless. Show details

Don't buy - just get a SIM card in the country you're going to – I received a physical SIM card from this company which was supposed to work in all the countries I was travelling to. I double checked with an employee before I purchased the product that it would work and they assured me it would. However, when I arrived, it did work for a few days and afterwards I experienced countless issues that I tried to… Read more

resolve with the live chat but even the employee trying to help me didn't know why it wasn't working. I had to resolve the issue myself and after somehow getting it to work in the first country, I experienced more issues in the next country and ultimately couldn't get the SIM card to work. At this point, I gave up and just bought another SIM card for the country I am in which works perfectly.

Terrible Service – No Order, No Refund, and Unjustified Charges – I ordered from WorldSIM and never received my order. Despite multiple attempts to contact customer service, I have been given no updates on my refund. Instead, I’ve been passed from one person to another with no resolution. To make matters worse, I was charged for 20GBP shipping costs even though I never received the product! This is completely… Read more

unacceptable.

Their customer support is unhelpful and dismissive. After over a month of waiting, I still have no refund and no solution. I would strongly advise against using WorldSIM – their service is unreliable, and their refund process is a nightmare.

Avoid this fraudulent company at all costs! – WORLDSIM is a SCAM, phony and extremely fraudulent company. It is even shameful to deem it as a company because if you look at the website, it's a joke because they claim to be a small team situated somewhere in the UK. The descriptions on their website is completely false and misleading. They say that they can provide you with an international… Read more

sim card with a US number. But all their numbers are sent out with a UK number, if you are even lucky enough to get the sim card delivered to you. They charge you 25€ (I KID YOU NOT) just for the postage from the UK to Germany and more if you are located somewhere else. This is a bloody joke because they promise you that you will receive the product within 3 days. But they actually ship out the product on the 3rd day so the product won't even reach you in 2 weeks. They then ship out your product with the wrong address or the wrong name even after contacting them multiple times to inform them about the right address, and then they have the audacity to mention on their website that they have a return policy but will only return the product amount but will not refund the postage amount, lol. That is if you even actually receive the product. And then comes the part where you have to contact them every single day for more than a month to fight for the refund and they will lend you a deaf ear saying they will look into it. Nothing gets done until you get sick of it and either let it go and choose to take it as a lesson learnt or just choose to initiate a chargeback on your credit card. Please take this from me, this fraudulent company will do everything wrong and then some more to make it the worst experience for you and all to avoid refunding you. Most of the 5 star reviews for WORLDSIM are fake and were written by themselves and you can deduce it if you look at them closely. No one, I repeat, NO ONE who has experienced their service would even think of leaving a half decent review for this crap. They have a blog which is basically generic articles written by AI and half of them do not even make sense. The "company" can be very closely compared to one of the scam call centres located in India. It works similarly and their customer support is THE WORST! If you make the mistake of buying anything from them, just forget your money or any hopes of getting a refund because not only will you not get your product that you ordered, but if you ask for a refund, they will act dumb and will make you frustrated enough to just give up trying to get a refund. They reply to your email with generic automated responses and they get you nowhere. If you want to waste your money and give scammers your personal card info, then WORLDSIM is your best choice. If you want good service and a product that you actually ordered, then STAY AWAY from this scam of a website. It's criminal that they even exist. Please, I implore you to make the right choice, check their website out, trust your gut feeling and avoid this fraudulent company.

DONT BUY THIS ! – I bought this international SIM (World SIM) for Singapur trip for 7 days through Bookmyforex.com. Paid around 1300 INR. though I got a NEXT Cellular SIM, No communication as to how to activate the sim was done. It did not work in Singapore. tried to contact Next Cellular contact. they did not help. wasted my money. looks like scam!! Show details

WorldSIM 2023 Experience – I just returned from Japan, where I gave WorldSIM one last chance. There was one network that I could occasionally get WorldSIM to work with. I had no service in Yokohama or Tokyo. My wife has Google Fi, and it worked flawlessly everywhere we went. This was a bit better than past experiences in Israel, Tanzania and Caribbean locations where… Read more

WorldSIM was useless, no coverage at all, though their website claims otherwise. I’ve spent many hours of vacation time trying to get WorldSIM to work. Only in parts of Europe and the United States has it been somewhat dependable. It’s extremely brittle, unpredictable, and will stop working for no apparent reason. It’s definitely not something you want to rely on if you truly need cellular service, or value your time.

Other issues I’ve had include inconsistency between information on their web site, printed instructions, and customer service responses. I’ve been charged for calls I did not answer, or when incoming calls were supposed to be free, and for using data when WorldSIM wasn’t working at all. It will switch from a preferred operator and nail you with predatory charges. I was charged $24.90 and $10.25 for data sessions of 1.658 Mb and 0.6 Mb. I was refused refunds/credit when WorldSIM did not perform properly, and received frustrating customer service responses that ignored my questions and/or claimed things that were not true.

I’m fairly astute when it comes to technology, but after more than 7 years of frustrations, using at least 4 different phones, I give up! I am baffled by all the positive reviews on some sites. I hope this one will help someone make a better choice than I did.

Great service – I have been using this service since the beginning of the year, it was great, and their customer service was quick and helpful

Faulty and refuse to respond to me – Bought a product from WorldSIM and it doesn't work. Support couldn't fix the problem and said they would send a follow-up email but they never did. I have asked for a refund and they have stopped responding to me entirely. Waste of money.

DO NOT BUY FROM WORLD SIM – I bought a phone and data bundle SIM to cover ASIA region travelling in July 2022. It took many hours of help to convince customer service that I was not connected. They were hopeless and just kept quoting the same information. Eventually I got connected and made one call to UK for less than 2 minutes. Stopped working again only to be told I… Read more

had no credit and needed to top up. Total Scam, It would have been cheaper to keep my usual UK providers package. People in my group bought from other providers with no issue at all. AVOID!

They are online scam and completely coruption – Please take care of them! they put me into trouble and paid lots of money for the SImcard which is completely unusable. My name is Zak and i ask them cone to here and reply !!! Show details

Unreliable and Hidden Costs – After just 2 years, I have just had to pay 32 pounds to get a new sim card as they have discontinued support for my current one and decided to upgrade their system and they have told me that I will also loose my number. (13 for the new card and 19 pounds delivery fee). Don't believe the website where they say free 3-5 day shipping as the online… Read more

assistant told me this was not possible... Very disappointed to loose my number and surely if they are the ones upgrading the sim cards and no longer supporting the old ones they should at least have covered the cost. Had it not been for the large amount of credit I still had, I would have wasted my time staying with them...

Paid Rs. 3588 for a US Number. Got a UK Instead that doesn't even work right – Absolutely disappointed with World Sim services. I booked their service via BookMyForex. They gave the Sim real quick but the SIM has scrambling numbers and I can't share this number anywhere. They have given a really weird reason stating that there's some issue with US numbers and their team is "working on the issue". After exchanging a couple of… Read more

emails, the issue still hasn't been resolved and now every time I use their International SIM, a different number reflects on the receiver's phone display. They have not bothered to fix the issue or even get back to me saying that there may be a delay in response/service. Highly! Highly Disappointing. Money totally wasted here!

This company is smoke and mirrors – This company is smoke and mirrors. Deplorable "service", fake reviews in TrustPilot, the Facebook Page is a joke, and they take users for fools. That "taking" includes inexplicable charges, eroding of credits, that can be interpreted as silent theft. Mysterious terms of service and constantly changing fees, that make tropical weather patterns,… Read more

seem stable. With over 40+ years in technology, and 6 of those being exposed to the "services" of WorldSIM, I cannot cut up my SIM card, into small enough pieces. This "company" is the epitome of being conned into parting with good money, to receive bad "service" in return. WorldSIM is to be given a VERY wide berth. Run, don't walk.

In the Past Was Fine Now a Total Joke – I have used this company for years but it has just deteriorated progressively over time to the point where it's now completely dysfunctional. An employee currently in Spain contacted them this morning it said that their phone line (UK) was not taking calls then he got eventually through to someone on another line it asked for a number to call him… Read more

back on but it seemed like the whole system is not working he's not keeping his fingers crossed because I warned him it's very unlikely they will return the call.

I don't know what has gone wrong with the company it used to be really excellent but it's so bad now it's frankly completely on usable and when you look at the reviews you can see that people are not even getting the product it's quite obvious they are tottering on the point of collapse.

The only place this card ever works is in the UK! I have tried it in AU, NZ, Spain, Germany, Mexico, US, Canada etc and it's a complete and utter waste of time occasionally you can use it to receive calls but can't make calls out other times it won't receive or enable you to make calls. Frankly it is the most horrific option for travel and causes so much stress it is absolutely 100% best avoided. If you contact support they go to all sorts of nonsense about taking the card out putting it back in waiting two minutes it just goes on and on I have another card from the Channel Islands which you just switch on and it works every time I just don't understand why with WorldSIM there is so much complication and nonsense. Looking elsewhere you can see that the whole service is clearly an absolute joke unless of course it's one of these positive reviews or something referring to someone called Annie which seems to be some sort of reply by the company themselves. I looked on Trustpilot and it was quite obvious that the reviews were in many cases false, why on earth Trustpilot themselves have not identified this I have no idea because it must be absolutely obvious to anyone with an ounce of common sense.

I've uploaded a proof of payment to the company but I can't be sure which of the cards we use this relates to as there are five or six but it relates to one of them and the problems are the same across-the-board regardless of which card is involved every single one is a total and utter waste of time.

SCAMMERS – Do not purchase !!!!! The "FREE" US number is a virtual number that cost you 17 cents a minute for incoming calls. They advertise free US number and free incoming calls. Now I am forced to use it and use up the credit or spend more money to ship it back. DO NOT do business with these SCAMMERS. Show details

Very bad customer service and experience – Paid for a SIM card 10 days previous to my trip. It didn’t arrive and when I asked for the refund, they put a lot of obstacles and haven’t done it to date. Show details

Never received my order and didn't get any answers either! – I'd ordered a sim card on the 6th of December for a trip on Christmas day - I have never received my sim card. Never received my order and didn't get any answers either after I opened countless tickets asking for a refund. Show details

No Delivery! – CAS-SXTS1555 refers. I have ordered a data SIM for my upcoming USA trip. Hasn't been delivered yet. No-one responding to this query. Not a great way to start a relationship... Show details

Tier 1 and Tier 2 support no giving support or fixing issues – I have opened a ticket on December last year (2019) , now we are in February 2020 and the issue is still not solved ( sim card not able to register in local network, phone calls not working, internet not working). Several emails have been exchanged with support (tier 1 and tier 2) also customer support and not formal explanation or solution was… Read more

given., Now they want me to buy a new simcard without confirming if this is going to solve the issue I have. I am asking several times for a refund and compensation because of this issue but so far they do not want to offer any of them. I am also requesting to escalate this issue to management and still not getting any reply just non sense updates with no permanent fix from customer support and tech support. It is really annoying not get a fix even after providing information and update a ticket several times in a month for the last 3 months.

Wasted money – Tried to use it in North America and Australia. The MoreCards application with an original WorldSIM SIM card most of the time either not registering in local networks or shows "NO SIM" . Completely dissatisfied with this product. Would give it below zero, if I could. Don't waste you money for it. Show details

Do Not Use – Pretty useless. I’m learning the hard way that it is much easier and cheaper to buy SIM cards upon landing in each country, even if you’re going to give different ones like me. Show details

Unreliable – Since i travel a lot I have used a Worldsim as my main number for quite some time. However of late the service has become hopelessly unreliable; in the last two months the following has happened: a) when you change countries you need to lock it onto the recommended supplier, this is seldom smooth and often requires the phone to be powered off and… Read more

the Sim removed. Since I can be in two or three countries in Europe in a day this is a real bind. Customer service are usually slow to respond with anything helpful and I have normally moved to the next destination before they try to do anything useful and the issue remained unresolved in recent visits to Hungary and Germany b) even when you do get it to lock onto a provider it may not make all calls. I find that it is normally fine for inter European mainland but calls back to the UK often dont work (recent experience calling home in Austria, Germany, Italy and Hungary). Oddly enough it seems to receive most calls and SMS is fine. This remains unresolved by customer service, they seem to have just ignored my numerous complaints as being too difficult despite a history of failed calls on the log. c) I have had consistent issues with their North American provider AT&T, my handset just doesnt pick them up. Again customer services have no solution other than a suggestion that my Motorola handset isnt compatible with North America. They eventually solved this by putting me onto another (more expensive) network d) the data bundles have been worthless, I bought one for a visit to Greece in October and it proved to be virtually unusable for anything other than reading emails and browsing. Video was just out of the question on their local network providers just not enough bandwidth - ended up having to use normal wifi. Additionally I couldn't call home to the UK from the sim and this was the other main purpose of buying the bundle. At the end of the validity period I still had most of the bundle left, unable to use it. My complaints to Worldsim customer services simply went unanswered. e) frequent changes in networks used and service settings make it difficult to keep track of what network to use and of course if you are not able to access the information because the sim isnt working you have to wait until you can get public wifi. f) Customer service are generally well meaning and are good at the standard issues. The stuff that I have is seldom within their capability and by the time they come up with anything I have moved on, the really hard stuff they just ignore. g) You never get the rates they advertise since they advertise a per minute cost but bill in increments of 2minutes. This can make quite a bit of difference if you have a short call or one which is 2minutes 1 second. As someone who travels for @ 9 months a year I should be their target customer however since the sim is so unreliable I now no longer depend on it. Only the dread of changing my number has prevented me from throwing it away.

Not a happy customer – WorldSim. This company sucks. I placed an order on November 20. Tracked it through DHL. they claimed it was delivered Nov 26. With a signature. It was delivered at a wrong address. Now, I've been going back and forth with WorldSim and DHL for whole month with no solution. It is now Dec 26th They claim, both WorldSim and DHL are investigating what… Read more

happened. I'm leaving for Asia in a week. With no wifi hotspot. I finally asked for a refund...WorldSim told me they'll get back to me. By the way, they've said they'll get to me each time. They never did. I had to initiate contact every couple of days. Everytime, they said they'll investigate I believe they'll never contact me and my money is gone. If and when I get my product and or refund. I will be more than happy to retract this review. Well, I'll still rewrite one... waiting well over a month for a resolution.
