Re: iPhone 4 dropping calls after 3-5 mins for about 2 days; Atlanta 30032
Thanks for posting. Are you still experiencing dropped calls? If so, have you tried any basic troubleshooting (i.e. a soft reset of the device)? To perform a soft reset, simply hold down the power button and the home button simultaneously. Once the screen goes dark, you should see the silver apple logo, and you can release the buttons.
If you've already attempted a soft reset, you may want to try a new SIM card. If you're the account holder, you should be able to visit any corporate store, and they'll activate a new SIM for your phone. If a new SIM doesn't fix the problem, let us know so we can get you in touch with our tech support specialists.
