WhatsApp is by far the biggest cross-platform instant messaging service around the world. Smartphone users rely on WhatsApp to communicate with friends, family and colleagues on a daily basis. WhatsApp is free to use but a data-driven app, making it necessary to have an active data plan on your phone or a Wi-Fi connection.

If you are roaming abroad or anywhere within your country, it gets tricky to find a stable data connection or even a Wi-Fi hotspot. Understanding these problems, an Italian firm Zeromobile developed a SIM card just for using WhatsApp anywhere in the world. This way, you can stay connected with others no matter where you are, without worrying about getting a special data pack or looking for free Wi-Fi.

Interestingly, ChatSim is not limited to just WhatsApp but also allows access to a wide range of apps including Line, SnapChat, Facebook Messenger, WeChat, Telegram, BBM, Kik, Imo, Kakao Talk, Hike and others.

WhatSim, which is now ChatSim, is available for purchase online in euros. The WhatsApp SIM card works in about 150 countries and connects to more than 400 operators to bring you the best coverage and signal. 

WhatSim (ChatSim) Price and Plans

WhatSim aka ChatSim is available for a base fee of €10 (Rs. 734) but you need to pay additional fee for using the SIM card. The €10 fee covers the cost of the SIM that comes in nano, micro and standard sizes. Additionally, a €10 fee will be charged as validity for 1 year, which also includes use of text and emojis. But if you plan on sharing images, videos or make calls, you will need multimedia recharge, which starts at €10 for 2,000 credits.

With 2,000 credits, users can exchange 200 photos or 40 videos or 80 minutes of calls with another WhatsApp user. You can add more credits to your ChatSim by paying €25 (Rs. 1,835) for 5,000 credits (500 photos/100 videos/200 minutes of calls) and €50 (Rs. 3,671) for 10,000 credits (1,000 photos/200 videos/400 calling minutes).

For instance, residents of India can have ChatSim shipped to their local address by paying shipping fees of €7.50 (Rs. 550). So buying a ChatSim with 2,000 credits will cost you around Rs. 2,753 (€37.50).

To put these plans in perspective, an average of 5MB will let you exchange 1,000 messages. There is a cap of 5MB per day, post which the data speed is slowed down until the next day. In case your credits run out, you can recharge for more anytime.

In the US, ChatSim is available for purchase on Amazon for $25.
