I have an older Black Berry Curve, straight talk. Internet connection has always been great. About a month ago I could no longer connect to internet (unless I was using wi-fi from home) The error says: Unable to connect to internet, if problem persist contact service provider. Straight talk has been NO help at all. Its appear I can no longer access Verizon? I have all the bars…The signal says No coverage IP address 0.0.0.0 Signal -103dBmM (Zero). Is there anywhere on the phone I can put Verizon as the carrier. Any help is much appreciated.
