I'm away from home country so can't take my phone back to provider. Needed to charge battery. Plugged in as usual. Has been temperamental in the past but always got going in the end. Not sure if charge has worked as cannot re-boot. Just stays on Yoigo logo and seems not to switch on or off! makes no difference if battery and/or SIM card in or out! Will I have to wait until I get home or does anyone know a fix?
