My phone won't send and recieve message. I can't even call/get a call but I can use my mobile data, the signal in our area is pretty good. Idk.. Is this a problem with the phone or the network? I've already downloaded the setting for internet and MMS but nothing works. In terms of mobile data.. I still have to contact the network and do the top up for my number to use for my mobile data since I can't send messages
