I have bought a Simoco Mobile Handset with IMEI no: [protected]. But it started malfunctioning after working for only 6 months. (note:still 6 months of warranty period left). Apart from this problem, I am also facing a lot of problems regarding this mobile handset like charging problems, set hangs frequently etc! The most unfortunate problem is that the display is showing invalid SIM in case of only SIM 2.I have inserted SIM cards of almost every mobile operators, but the display is same i.e. "Invalid SIM". The company tagging "desh ki awaz ko sun" will certainly hear the "awaz" of the peoples if this kind of worst service continues!!!! Was this information helpful? |
