We're trying Text Plus out as an alternative to paying a carrier for a texting plan. This is a 1.99 iPhone application. It's basically group ware.We cancelled our texting plan so nobody can text us directly now. Text Plus fixes that indirectly but there is a catch.
Text Plus is built around communities. You can create a named community and then ask people to join it using either TEXTing (their phone number) or their text plus id if they have it. Community membership can be open or closed. You can indicate if only you as the creator can invite people or any member can invite someone or people can invite them selves.
Each community gets its own real phone number that looks like 60611XXXXX. If you invite someone with a TEXT capable phone then they receive the invite, do some registration, and then they are in the community. They should save the 60611XXX number so that they can later send messages to the community paired with that number.
It's important to realize that ALL members of a community receive all TEXTs send using that communities 60611XXX number. If you want private texting between you and someone else, make a closed community with just that person as the other member. That private community has its own number like 60611YYYY and then they can text with you only using that number. This best maps to a traditional text operation. Your friends will use this specific number to text you like before rather than your phone number.
Communities with multiple members are handy to keep a bunch of people with phones in touch. It's a bit like a private facebook group or something but works with texting pretty seamlessly. Handy for lunch calls at the office and so on. A private twitter is comparable.
Your iPhone or iPod Touch receives notifications when someone in one of your communities sends a text. Thats basically all thats to it. The registration only has to be done once per phone so once someone registers with text plus then its very easy for them to join other communities.
People can find out about existing communities by texting the community name to 60611 and then it replies with options if any are available.
So far, it's ok. We made a group for family texting, one for myself and my friends and a couple of private ones for 1-1 texting with my wife and so on. I guess we'll see moving forward how it goes.
