Sony Ericsson K750i no network coverage solution

SOURCE: sony ericsson c905 no network coverage

Hi

Thanks for using FixYa. Please check the sim card first because it might not be making good contact to the prongs. It's not the phone causing the ‘no network coverage’ issue, it's either the sim needs to be removed and wiped off with a soft cotton material and then reinserted or it's the network having problems itself. Also try the sim card in another phone. If it works, then the problem is with the handset. If the sim doesn't work in another handset then contact your network provider to get the sim replaced. If it is still under warranty you'll need to take it back where you purchased it from to get it repaired or replaced.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

*#3370# - Enhanced Full Rate Codec (EFR) activation. Increase signal strength, better signal reception. It also help if u want to use GPRS and the service is not responding or too slow. Phone battery will drain faster though. (type this on the main screen)
