PLEASE HELP, Treo not connecting calls sometimes!

[gusanitoverde]

I just got a Cingular Treo 650 on ebay. The Phone is great, blameless, and worked great for a week. Well, I don't know if it has to do with this 4th of July weekend, but, I am trying to dial my phone and it reads: "Dialing" but never connects and ends up dropping the call. The only way I could dial is if I turn off and turn on the phone again, and while the phone is making the "network search" I am able to place the call. However, once I hang up, and try to make another call, the call won't connect. I have a good signal strenght. And by the way, I had the sim card replaced twice already just in case it was it. I am very irritated now and I don't know what to do. Is it my phone or is it Cingular? I may be still on time to cancel my 2 year contract and move to Sprint. (I would have to change my Treo for a Sprint one though)

Any ideas anyone? :( :(

Hmm, don't know, might be with your carrier. I have Sprint and thankfully never had that problem. :(.

You can also try out Verizon, No problems so far here either.

I went out to visit someone, and as soon as I came out of my house, the phone picked every call and so made it too. So the problem is isolated where I live... Why?
