WhatsApp launched WhatSim, a WhatsApp-only SIM that comes with a plan for free while travelling across about 150 countries.

WhatsApp is one of the most popular instant messaging services worldwide, with the company recently announcing 700 million monthly active users. Now, in an attempt to woo the large WhatsApp user base, an Italian company has launched WhatSim, a WhatsApp-only SIM that comes with a plan that will let you use the popular messaging app for free while travelling across about 150 countries.

WhatsApp finally makes the jump to your web browser.

The new messaging service currently only works with Google's Chrome browser and will not be available to iPhone users "due to Apple platform limitations," according to WhatsApp.

Mobile messaging service Whatsapp is now available in web server.

WhatsApp can be connected by https://web.whatsapp.com in a Google Chrome browser.

Update the WhatsApp app to the latest version in your phone.

WhatsApp banned them for 24 hours because they violated the app's 'terms of service' by using a third-party client.

Some users are reporting WhatsApp banned them for 24 hours because they violated the app's 'terms of service' by using a third-party client.

Users are reporting about the ban via different social networks (Facebook, Google+ and Twitter) revealing that the ban is only for those Android users who are using the popular third-party client WhatsApp+ or WhatsApp Plus.

The company is now asking users to uninstall WhatsApp+ and install an authorised version of WhatsApp from official website or Google Play to reuse the service, although the 24-hour ban period will reportedly remain in effect for the full duration despite replacing or uninstalling the app.
