Hi friends, I expressing my experience with airtel mobile network. I am living in a hilly place of Malappuram district of Kerala. When I passed my higher secondary examination I brought a new mobile phone there for I forced to take a sim card for that mobile. I bought a sim card of company but the range of that network is very poor in our locality. Thus I brought another sim card . First time there is no problems but latter problems arrived. In this time the port facility available in our markets and I ported my number to airtel mobile network now a experiencing good network when calling and browsing internet. thank you airtel.
