This morning when I went to school my Samusng Galaxy S3 was working fine however after school i could not make outgoing calls but i could receive them, i could not send text messages but could receive them and anything that invovled the internet was not working. I have data network mode activated so there should be internet access. I am on a plan with 1 gb of internet if that helps. Has this happened to anyone else? If so can someone please tell me how to fix it.
