Help Connection drops. Must reboot to get it back

[pstuverud]

My new Ace 2 running on AT&T network occasionally drops both data and voice connections, even in strong signal areas. When this happens it does not automatically re-connect. I have to manually power-off-on to get the connections back. Shouldn't the phone do this on its own? Could this be a defect in my phone?

Never had this issue. Try to do factory reset..

I've done a factory reset & still have the problem. Actually it's now worse. It now happens more than twice a day, making the phone almost useless. I tried moving the SIM card to another phone & it works fine there, so it must be the Ace 2 that has the problem.
