Reception Poor signal in and out. Many dropped calls. Yet there advertisements can get through.

Currently I am using a Cingular prepaid sim card. I was recently upstate NY (in Delhi) and could not get a signal at all. When I called Cingular about this problem, I was told it was because I was using a prepaid sim and did not have a plan, therefore, I could not roam to different towers. I always have full bars on the Island but I want to be able to use the phone away from home. T-Mobile has a USA Max sim for $139.00 that can be used across the entire US and for International calls also. I'm thinking of switching to the T-Mobile sim card because I do not want to be locked into a plan. Does anyone think I'm making a mistake switching to T-Mobile?

I had this phone from when At&T was still a seperate entity. They were a godsend, Cingular is a nightmare. While the gsm service was wonderful. After the takeover by cingular, it seems that maintainence has fallen victim. My phone still gets better reception in buildings basements and out on the east end (the hamptons), than my friends with Verizon and sprint. but I often experience dropped calls or not being able to connect with no explination (my phone is reading full bars). But this is not the worst problem with cingular. almost every other month since they changed over I have had some kind of billing dispute with them. The contract I signed with AT&T said that I could change my plan at any time and have the changes appear on my next billing cycle. When I removed the wireless internet option they tried to tell me that it was going to take 3 months for the change to take effect. Just recently they turned off my service for a day because they had a check declined. the problem was with my banks check 21 system, but they never bothered to submit it a second time (working within a processing company I can tell you resubmitting is almost standard with the check 21 system). they just cancelled my service. once I got them on my landline my service was back on within an hour. But this month they tried to charge me a reconnection fee of 25 dollars (they did waive this fee once I contacted them about it). They also do not provide the numbers of incoming calls on your monthly statement, which has been an issude for me in legal matters. in short the gsm service is good, the company running it is not.
