This has happened about 4 times now this month. My phone will have that circle with a slash showing no service. Its where I ALWAYS have service.  A restart of the phone seems to fix it. Is it something wrong with my sim card or is it an issue with my phone?

Try and resetting your network settings and restart the phone and see if that helps.

If you haven't already, try this


Press and hold Side key until you see Power Off - select it to power off the phone.

Now, off to the Maintenance (Recovery) screen:

Press and HOLD the Volume Up key, and while holding, press and HOLD the Side key.

When the Samsung splash screen appears, release both keys. Within a few seconds, you'll see the Maintenance screen, with a number of menu options.

Use the Volume Down key to highlight Wipe Cache Partition. Press Side key, select "Yes".

Now, Use Volume key to highlight "Repair Apps" (should be last menu option). Use Side key to select it.

The phone will automagically restart. Let the phone settle down for a couple of minutes.


... check and see how things work
