Hi manishchib,

It appears you may have Airplane mode on. Here's how to turn that off if needed:

Use Airplane Mode on your iPhone, iPad, iPod touch, and Apple Watch

If that doesn't fix it, you may still want to try a different network like cellular data and reset your Apple ID password if you haven't done so. Also, if you have any VPN apps or profiles installed you may want to temporarily delete those to see if the issue persists.

Take care.

Hi manishchib,

A factory reset may solve the problem or it may not solve the problem. There may be something else wrong.
