first i stuck on sad face while resetting my phone , then i took it to service center and they reset it, now in some place my mobile shows no service problem , other phone works fine but my phone doesnot shows service, again i reset and update to latest os windows 10, but that problem continues, does os or firmware effects in network, i know that network chip is fine because in some place it shows service. is there is any troubleshooting software?? suggestions please???
