My handset server cant respond(repaired), is he lying?

My Alcatel 585D handset can't turn on, so l hard reset by pressing #, it came on but Opera mini browser "can't connect to internet"! The repairman is perplexed that my phone's server can't respond, l remembered my seller tells me to get a new model phone, my question is:Can the browser be ever reinstalled?
