The Line2 app is now available for Android phones and tablets. Toktumi announces that its SMS-enabled VoIP app can now be downloaded in the Android marketplace. Line2 becomes the first VoIP app for Android to feature carrier-grade SMS texting combined with feature-rich calling functionality, allowing customers to use one number for both types of communication.

Customers use Line2 to add a second line to their smartphone or turn an iPod or tablet device into a fully-featured telephone. The app allows customers to make phone calls and send texts where they don’t have cell reception, reduce their cell bills, add a second line for business use, or get another number so they can keep their personal cell number private. Many customers take advantage of Line2’s free port-in offer, which lets them move an existing number to Line2 free of charge.

Line2 for Android includes all of the functionality and features that are currently available to Apple iOS users plus few Android-only features, such as the ability to speak their text messages and have them transcribed so they can text without typing.

No other app offers the features and functionality of Line2. Line2’s tri-mode VoIP/cellular calling capabilities allow Android users to place and receive calls over Wi-Fi, 3G/4G data, or cellular voice networks using the same number, ensuring that calls will always get through. If Wi-Fi isn’t available, Line2 can use the phone’s 3G or 4G data network to place or receive the call. This allows callers to avoid cellular minute charges while still having complete mobility. If a reliable data connection is not available, for example while in a moving vehicle, Line2 can still place and receive calls using the phone’s cellular voice line, although with the Line2 number. The application detects the best available network based on customer preferences and places and receives calls over that network automatically. This allows customers to use one app and number for all types of calling, an industry-first.

Line2 for Android offers full backgrounding support. This means customers can receive calls on their Line2 number even when they are running other apps, browsing the web, or listening to music. Line2 customers can be sure to never miss a call, even if they don’t have cell reception.

The app’s Wi-Fi capabilities allow international travelers to place and receive calls while overseas without incurring voice or data roaming charges. When using Line2 over Wi-Fi, calls to any number back home will be free as will calls to other Line2 users, wherever they are worldwide. Calls to international numbers start at $0.02 per minute, whether calling from home or abroad. Line2’s Wi-Fi call quality is better than traditional cellular quality, and Wi-Fi calls between two Line2 customers use 16-kHz HD audio for crystal clear sound quality that is stunning to experience.

Line2 is a free download that comes with 30 days of free service. After that, service costs just $9.95/month for unlimited US/Canada calling and texting.

Also available for Android is Toktumi Unlimited which comes with all of the features of Line2 plus business PBX features like auto-attendant ("Press 1 for..."), call screening, caller-specific call forwarding, after-hours settings, and Mac/PC-based calling for just $14.95/month.
