When my husband and I decided to get cell phones, we couldn't afford the deposit so my mother added us to her plan. We upgraded the plan, since their were now five people on it, and conveniently got the mycircle plan.
How this works is you can add up to ten numbers, cell phone, home phone or office numbers. We all call at least three of the same numbers all the time so we added those. Then we split up the other seven between the most called by the rest of us. We also split the bill so it was even between everyone.
I talk on my cell phone a lot and always end up using the most minutes. If we didn't have the mycircle plan, I would run over my minutes every month. Last month, for example, I talked 2600 minutes on my cell phone, almost all of that was covered by mycircle and mobile-to-mobile, which are essentially free minutes. They don't count toward your allotted minutes of use each month. This plan is an essential if you are a talker! I would recommend this to everyone!
