Query: 9 months - many problems

We bought 2 phones on a family plan last October. We were looking for a very basic flip phone capability, no bells and whistles needed. Our major use was to communicate between each other. We were happy for for about 5 months. Since then we have experienced all the problems mentioned. Our phones were replaced during April. One sim card was replaced during June. Yesterday we again replaced our sim card on the same phone. Another replacement phone is on the way to us. The major problems have included "service not available" even though 4 bars are showing and the other phone works at the same location, "unable to read", "insert card", and of course dropped calls. Yesterday as I was talking to a warrantee agent trying to resolve our most recent problem my call was dropped in the middle of the call. At this point I have concluded that this model is extremely unreliable and am looking for an alternative solution. I can not depend on it. I would not recommend it to anyone.
