I am writing on behalf of my poor daughter who decided to spend her $50 vacation shopping money on a Chinese made dual sim cell phone, with analog Tv & many other wonderful features. Brand name is M.REN, bought in the Philippines. We were assured by the salesclerk this would work in the U.S. Her Globe (local) Sim card worked fine in that country. Back in the U.S. now with prepaid AT&T sim card in 2nd slot, only to find " No service" on screen.. Tried to select EDGE and Cingular among the preferred networks shown on network setup list but it was not able to register a network. Can she ever use this phone here? Many thanks for any help
Answer I was not able to find any information on a phone called M. Ren. Is it possible that it called something else? Can you see if you can find a different name on the phone and I can tell you what I can find out? If it is a tri-band phone, then the reason it most likely won't work is because it doesn't transmit in your area on the band that AT&T is using. If it is quad band (i.e., works on 850 and 1900 in the US), it should be working with AT&T (i.e., either EDGE or Cingular). If it is quad band and doesn't work, then it is a defective phone, I'm afraid. Let me know more details and I will try to help. I'm very sorry that she spent her hard earned money on this junk, though. I try to caution people not to buy phones from Chinese manufacturers. They are very troublesome. Thanks. DebiN
