Can any one of you kindly suggest me which is the most lovable mobile phone?

I would most certainly suggest the Motorola. I am on only my second Motorola phone in 9 years of having my cell phone. The other one was the original Startek from many moons ago. The one I have now is the Motorola E815. It's probably old enough to where you might not be able to find it anymore. But I certainly would suggest a Motorola for you. My old boss and I both had the same cell phone carrier. I had my Motorola and she had a brand new LG. Guess what? When she didn't have a signal, I still had 2 or 3 bars. It gets great reception. Good luck to you! I hope you find a phone that you love and do not have to replace in a number of years, just like me. Have a great day!
