I have been using this phone from 5 years. Very good battery backup. Strong, easy to use, good sound clarity what not. I have compared my phone with many models and many brands.
But found my phone is strongest and reliable. I have not even changed the battery(it is the original came with the mobile) Till date I get battery back up for 3 days. Cool piece worth of money I have spend.
When compared to other model, I found people having many problems with sound clarity, battery, some had screen problem, bla bla.......But found many users of NOKIA 1100 with ZERO problems.....SUCH A GR8 piece.
The mobile so strong, I have dropped many time on the floor by mistake nothing happened. ……damage NIL. I am not giving any advertisement to NOKIA but this is from my HEART. Thanks to NOKIA to design such a strong model. Hope NOKIA keeps its quality for ever.
