Send SMS directly from Chrome

Google’s Chrome browser is head and shoulders above the competition in terms of user numbers. Thus, it is only logical to release our browser extension for sending SMS in Chrome as our first one. We sincerely hope that you’ll enjoy using it!

Why Chrome?

Chrome is where the users are. In Germany, almost 45 percent of Internet users are on Chrome. Worldwide, it’s even more impressive at 69 percent. The browser’s popularity is certainly based on several reasons. This starts with the built-in compatibility with popular Google apps. Users also like the speed – Chrome tends to launch faster and load pages quicker than the competition. Although Chrome is the newest of the “big” browsers, it has very quickly claimed the top of the market.

However, the browser’s market dominance also has the effect that some websites are not only optimized for Chrome, but are completely incompatible with other browsers. Some of these are Google’s own websites, others are third-party sites. There are only two ways of dealing with this: Either you don’t user the particular website, or you use – at least for these pages – the market leader.

What Chrome has not been able to do so far, despite all its great features, is send SMS. We have addressed this flaw and offer our new browser extension.

After downloading the plugin as a .zip file, unpack it into any folder on your computer. Got to chrome://extensions in your browser and activate developer mode. Click on Load unzipped extension and select the folder you just unzipped. Now the sms77 extension should be active.

Update January 2020

To send SMS you need an sms77-Account in addition to Chrome and the plugin. Under the menu item Developer you can create and copy your API key in the corresponding section.

Sending SMS in Chrome
