Xperia doesn't recognize the SIM card

[xiu17]

recently my Xperia was downloaded which only happened for about 30 minutes then I put it to charge but I left it until the next day and the morning I went to school I turned it on but no longer had a signal I thought it was a simple problem which I take it to restart it then to restore it from the factory but the problem persists I hope and somebody I have the solution sad

hace poco mi xperia se descargo lo cual solo paso durante unos 30 minutos luego lo puse a cargar pero lo deje hasta el dia siguiente y a la mañana que me iva a la escuela lo encendi pero ya no tenia señal pense q era un problema sencillo lo cual me llevo a reinicirlo luego a restaurarlo de frabrica pero el problema persiste espero y alguiwn tengo la solucion

I'm sorry to hear about your issue, could you test a different SIM card ?
