AT&T customers with iPhones may be experiencing problems with their smartphones, as thousands across the country say they are not being able to make or receive calls. 

Affected customers are reaching out to AT&T on social media, asking for a solution. 

The company is advising customers to turn their phones off and then back on. 

If you've experienced an issue when making wireless calls, please restart your device, this might be required multiple times- that should resolve the issue.

According to AT&T, the outage should be fixed by Thursday. 

Here is another temporary workaround: 

• Go to iPhone settings
• Cellular (4TH down)
• Cellular data options
• Enable LTE
• Choose 'Data' only
• Reboot

The way to figure out if the issue is fixed is to turn back to the “Voice&Data” step. 

If it is working, it's fixed. If not, turn back to "Data," only.
