My first guess is either a badly-seated or faulty SIM card. If it's a new SIM, it may not have been correctly activated by the network. In either case, try it with a known-good SIM - if it works then the issue is with the original SIM. If it doesn't then it's likely a faulty SIM reader on the phone itself.
And in all honesty I didnt have any trouble till put the lightware rom on
I have no phone number back tp saying tmobile network... gonna try putting stock mj4 back on see how that works.. bit straight talk is suppose be sending me new sim.
