It’s widely accepted that using mobile data abroad is a recipe for bankruptcy. There are far, far too many articles on The Daily Mail and The Telegraph of hapless tourists who decided to stream some TV, or download a Neil Diamond album (choice quote: “I’m really not that big a Neil Diamond fan”), only to be stung with a multi-thousand dollar bill. 

As a frequent traveler who visited 11 countries last year, I’m in favor of anything that makes it affordable to use the Internet abroad. I should be excited about the WhatSim. But I’m not. In fact, I’m downright cynical, and you should be too. Here’s why.

What’s A WhatSim?

WhatSim is a SIM card available to purchase online for €10, plus €5 shipping. But it’s not like any other SIM card. It allows the user to use Facebook-owned Facebook WhatsApp, SkyDrive OneDrive, Yahoo Siri, Apple Tesla [Tech News Digest] Facebook WhatsApp, SkyDrive OneDrive, Yahoo Siri, Apple Tesla [Tech News Digest] Facebook buys WhatsApp, FCC responds to the loss of 'net neutrality', SkyDrive becomes OneDrive, Yahoo wants its own Siri, Apple is interested in Tesla, and Samsung mocks Apple in its latest set of television commercials. Read More IM service WhatsApp Better Than Text Messages & Free - WhatsApp For Android Reviewed Better Than Text Messages & Free - WhatsApp For Android Reviewed A moment of introspection, please: What do you do more often - call people using your phone, or text them? I would bet it's the latter. For many people, texting is more convenient than calling.... Read More in any country, without limit, for a year.

whatsim-home

It’s available in nano, micro, and standard SIM sizes, and WhatSim even promises to refund the $1 fee you pay to use WhatsApp starting from your second year on the service. What could possibly go wrong?

… Terms And Conditions May Apply

When WhatSim talk about “unlimited Whatsapp”, they’re not talking about the full functionality of the app. They’re not talking about unlimited voice messages, and photos. Nor are they talking about videos. They’re talking about text messages.

If you want to share your holiday snaps with your friends, you’d better be prepared to cough up.

In addition to the €10 you pay for your sim, you are also expected to buy “credits” in order to send non-text messages. €5 gets you 1,000 credits, whilst €50 gets you 10,000 credits.

Media messages are charged dependent upon the location you’re in, and by the size of the message sent. A photo in the United States will only cost you 20 credits (€0.10), but the same picture in Barbados will cost you 200 credits (€1.00). A video in Slovakia will cost you 100 credits (€0.50), but the same video in Argentina will cost you 800 credits (€4).

whatsim-pricing

Four Euros for a vine-length video. Hardly affordable, is it? Frustratingly, media messages aren’t listed with a currency value on their pricing page, making it slightly opaque how much everything costs.

Surely there’s a better way.

Are There Any Cheaper Alternatives?

Absolutely. If you live in the EU, you’ll be glad to hear Brussels is gunning for the phone companies, and will soon make intra-European roaming a thing of the past. They’ve already massively slashed prices within the 28 nation block. You can read my coverage on it here The EU Just Made Using Your Phone Abroad Cheaper. Here’s Why. The EU Just Made Using Your Phone Abroad Cheaper. Here’s Why. Thank EU! Rules introduced by the EU designed to control the cost of using mobile phones abroad take force from the 1st of July. Read More .

But what if you’re traveling outside of the European Union?

Well, even there, it’s almost always cheaper to just buy a local SIM card.

Take Argentina, for example. With Argentine network Personal, you can get a SIM card with 5000 messages and unlimited data, valid for 5 days. Total cost? $22.90 Argentine Pesos. That’s about €2.30. Sending just one vine length video with WhatSim costs €4.00. 

whatsim-buenos

Looking at the United Kingdom, we can see Asda Mobile has offers 100 minutes, 2000 texts and 100mb of data for only £5. At current exchange rates, that’s close to €6.60. With those 100mb, we could send about 2000 images at 50 kilobytes each. For the same price with with WhatSim, we’re looking at closer to 130 images.

Planing a trip to Abu Dhabi? A gig of data with local provider Etisalat will cost you about €22. With that, you could send around 20,000 pictures at 50 kilobytes each. But at €0.75 a picture with WhatSim, €22 will only get you around 29 pictures.

It just doesn’t compare, does it?

Repeating History

Of course, WhatSim isn’t the first company to take a flat-fee approach to mobile usage.

Last year, crowdfunded mobile network Ovivo hit the UK. Their offering was pretty simple. Pay a flat fee, once. In return, you’ll get a certain amount of minutes, messages and megabytes of data. For free, and for life.

Predictably, this wasn’t sustainable, and Ovivo folded amidst much wailing and gnashing of teeth. Punters who had forked out for a SIM ended up out of pocket, and unable to transfer their phone number to a different phone network.

whatsim-sim

Also last year, UK community driven MVNO What Is an MVNO and How Does It Save Money on Your Cellular Bill? [MakeUseOf Explains] What Is an MVNO and How Does It Save Money on Your Cellular Bill? [MakeUseOf Explains] In the US and Canada, we're taught that we need to sign contracts because cell phones and cellular service are so pricey. That's a bald-faced lie. Read More  Giffgaff eliminated their (competitively priced) unlimited data packages. The reason? A small section of heavy users made it economically unviable for them to offer all-you-can-eat data.

The lesson? If something sounds too good to be true, it usually is.

And yes, I can’t predict the future. But I can look to the past, and I can see Ovivo shutting shop as a result of their ludicrously short-sighted business model. And I can see Giffgaff re-evaluating their pricing after it became apparent their service wasn’t sustainable. From that, I can see WhatSim either folding (after all, roaming is very expensive), or having to change their pricing to a less attractive one, as a result of a handful of heavy users. Or, they’ll just keep on charging ridiculously high fees to send pictures, videos and voice messages.

Just Get A Prepaid Sim

If you travel to a lot of countries and you only really want to send text messages, then maybe, just maybe WhatSim is worth getting. But everyone else will find they’ll get a better deal by purchasing a local SIM card when their plane touches down.

Have you got a strategy for using mobile data abroad? Let me know.

    Mate:
    As an international airline crew, I think this deal is pretty good,and if you are talking about travel extensively, I travel between different country in Africa, Europe, Asia, N or S America every month, each time average about 1-2 day in each country.
    I use to collect the different SIM card in every country, but a lot of SIM card in only valid for 3-6month, than it expired, so I will need to buy SIM card every single time, unless I can limited myself only go to few destination, but that sounds a little too much.
    I agree with you the function is pretty limited, but it is still better than pay 6-10Euro every country, at least in my case, I think I can accept the limited function for the function.

    Good lord, so much discussion and NOTHING about how this sim works in a locked phone! If you are traveling from the US, which most who are interested in this sim card would be, you most likely have a contract and a locked smartphone. If you have AT&T for example, you can't unlock your phone without being out of contract for at least 1 year. When we travel internationally, we bring along a cheap Samsung clamshell phone which works beautifully for local sims in just about any country. But your smartphone? You might as well leave it at the bottom of your travel bag. It will be useless until you land back on US soil. How can you write an article like this without mentioning the locked phone issue?

    • Matthew Hughes
      February 23, 2015 at 9:38 pm

      Well, if the phone is locked, chances are high it won't work. Period. But the trend is that the majority of phones are being released unlocked. At least, in Europe.

What you stated is not new, everything terms and conditions of the usage are stated in the Whatsim website. Yes we know that we can only text, but that's what most frequent travelers and crew working in the airline industry needs. The perfect solution to texting home to our loved ones and with the convenience of 1 SIM card at 10 Euros without needing to pay for a new sim card to every single country we visit. WIFI is abundance in most countries and hotel now. So yea I agree with Wilson, you don't have a clue what you are complaining or arguing about. LOL

    There seems to be enough wifi hotspots around the world to be able to most of your data heavy lifting. Because of that, WhatSIM does not have to do any of that. However, in most areas of the world where there is no wifi, but there is cell service, WhatSim provides a very cheap means of communication. This is no data plan, but at $15 a year, it does not have to be. If the argument that most of the WhatSim add ons are an enormous rip off, I agree. So do not use them. However, unlimited WhatsApp texting from most areas of the world that has cell service, for $15 a year, is incredibly handy, and incredibly cheap! Sure, WhatSIM is a one trick pony, but man what a trick!

    Thumbs-up for the comments but thumbs-down for the article. The only adding-value part of the article is that it may sound too good to be true, but text messaging with whatsapp consumes almost no data at all and that could make this project profitable enough to be sustainable in time... anyway, I'm willing to pay 15e for one year to see if it works. For me is a win-win situation because I'm an immigrant in Canada and I receive a lot of visits from abroad during the year, and I also travel a lot to many different countries during the year (work and leisure) so with only one SIM and a low flat yearly rate I could solve the problem to keep my visitors communicated all times and keep myself communicated all times as well when travelling.
    My only concern will be to know what network companies will work with WhatSim (to know if I'm fully covered in the country where I'm travelling) and if can I deactivate the reception of data to not receive multimedia files while using the service or be able to use only wifi connection for multimedia files when available. Also I think that an unlocked-whatsapp-capable cellphone is needed (which fortunately I have).
    I can wait to read the reviews when the service becomes available. We will see...

    Whatsim really IS a good deal! Collecting multiple local sims really IS a nonsense (unless you have one if you spend a looong time on one place abroad...)
    One single Whatsim is a trouble-free solution always in your pocket (or phone) without any need to spend hours searching for the best local data pack offer and hunting local sims resellers instead of enjoying your private holiday or a business trip.
    And ABOVE ALL it is NOT meant to replace your laptop, smartphone or any other device capable of wifi connection that one can usually find in hotels, restaurants etc. and use to transfer unlimited numbers of photos, videos or other kinds of high data volume files. Whatsim is primarily about being constantly reachable and able to reach anybody else - moreover with the advantage of automatic choice of the best roaming signal regardless on your normal sim operator's policy...
    Have you ever traveled? And impatiently had to search / wait for a free wifi hot spot while you had a really urgent message to deliver or a question that could not wait to ask? Or ended up without signal of the roaming partner of your operator while other networks performed perfect? Yes! Whatsim solves all these blind spots (paid Wifi at the airports, in hotels, or no wifi along the trips by cars, taxis, buses, trains or just walking around the city or jungle ;-) And believe me - time you spend out of the reach of free wifi is really more frequent and longer than the one your devices are wifi "covered".
    Just use Whatsim for what it serves best and that is it!
    Nobody wants a sports car to plough a field on a farm... as tractor is much better for this job. Then why you expect Whatsim to transfer tons of files instead of appreciating fast, cost free and ubiquitous possibility to share any joyful or in worst case urgent or even "life saving" info?
    I will go for it for sure ;-)

      Yes. I have. I usually go abroad once every couple of months. Last year, I visited 11 countries. I personally know how expensive roaming costs are, and I'm acutely aware of how annoying it is to not be able to use mobile data abroad.

      The difference is, I don't think WhatSim is the answer to this. An expensive SIM which works with only one messaging app? No thanks. I'd rather just spend €5 EUR and buy a SIM in country.

    WhatSim is a good deal, how do you expect to send Photos, Movies and voice message with a flat fee?! This is expected that those are extra, after all they have to do deals with Network providers for Connectivity, they don't own them, they must pay for that bandwidth that you use... Nothing is free, especially when roaming.

      Exactly. Nothing is free. Which is kinda my point.

        Dear Matthew! ChatSim has never claimed that the service is free. You can exchange unlimited instant messages and emoji, through the most popular chat apps ( and we are working on expanding the list of the compatible apps), for only 10 euros a year, which is insanely cheap. also, the rates for exchanging multimedia are published on our website. Everything is transparent

    You are right.....partially!
    If you spend a long period in a single country, local sim is the solution.
    But what about if you visit 7-8 different country in a month? And stay in that country 1 or 2 days max! In this case whatsim is the perfect solution. If you need to send media file, just use the wifie connection of the hotel that, most of the time, is available for free.....or go in a Starbucks!
    I will go for whatsim 100%!!!

    What if I told you that I only text through whatsapp and a month of Internet in any European country cost you like 8e and that the cheap ones... Whatsim looks like a good deal, it's less than 1e per month. Ahhh and I have dual sim phone.

      Really? You can get a sim card and £/€5's worth of credit pretty easy in the UK, and France, and Switzerland....

      Oh, and that credit will let you use the entire Internet. Not just some of the functionality of one app.

      Dear Fabii, Kekes and Matthew,

      WhatSim has evolved. It is now called ChatSim. ChatSim World ( our new product) can be used with many more apps now: WhatsApp, Facebook Messenger, WeChat, Telegram, BBM, Line, Kik, Hike, Kakao, and QQi. These are all popular apps. We are still working on expanding this list. ChatSim World can work with 4G technology. It has a firewall that can block unwanted data traffic up to 90%. You can connect to more than 400 operators in more than 150 countries.

      Matthew, ChatSim, as you can understand from the name, is not an internet sim, but a chat sim. You cannot use it for other features ( browsing the internet, etc), and this is very clear. ChatSim was born for people who travel a lot and don't want to be out of touch with their loved ones, while spending very little ( 10 euros a year is a very cheap price). the main priority of this people is to send text messages to their friends and family.

      You can buy a sim for 5 euros in those countries, but you can use them in only ONE country. Or you can buy ChatSim for 10 euros , and use it in 150 countries.

      If you want more information, don't hesitate to contact us: info@chatsim.com

    This is a good breakdown of the fine print. And, no, I don't think the WhatSim sounds like a bargain. I'd love to see a chart that shows the names and options on some of those cards in common travel spots. My wife and I travel back and forth between the U.S and Europe a lot, enough that it doesn't make sense to have year-long contracts in either place. So we do a thing with T-Mobile in the US where we buy use-anytime credit in $100 blocks, which includes some data. It's not ideal but the best option we've found there. And in the EU, where a lot of the time is in France, we do Joe Mobile, which is a flat 20€ per month for 2GB of data, unlimited text and calls, including calls to the US. The selling feature there is that the account is easily managed online, including the option to suspend the account (and charges) via app, when we're not in the country. That's a pretty specific option, mostly for France travelers, but still...

    Even despite your reservations, it sounds pretty good to me. In the 10 countries I've been to, if I'd bought a local sim for each one, it would have cost me upwards of $100. All for a few Whatsapp messages and maybe a couple of texts. The only reason I'd need the SIM is generally to get in contact with people I'm staying with, or a couple of people I meet along the way (usually Facebook via wifi suffices). From my experience, most of these locals and travelers use WhatsApp (especially in Asia). So, with all of this in mind, I want a Whatsim! ;)

      You want a hugely-restrictive, expensive SIM which only works with some of the functionality of a single app? fair enough.

      Something about fools and money.

      It'd save me money, over needing to purchase a new sim for each country I visit (which works out at $5-10 a pop, usually not including any credit). Often when using AirBnB, hosts ask for my WhatsApp name, but I can't give it to them, as my phone is never on... if I had this SIM, it'd help me out a lot.. The other features are not things I need..... :)
