Re: [apple-iphone] Switching from WiFi to cellular

 

This is not unusual and I would not consider it a problem. When you turn off data, your carrier no longer has contact with your phone. When you turn cell data back on, the carrier has to reestablish connection and verify your phone. The fix is to not turn cell data off.

When you turn off wifi on your iPhone, wifi no longer has contact with your iPhone, correct? When you turn wifi back on, your iPhone searches for a wifi signal, correct? Isn't it the same with a cell signal? iPhone cellular gets turned on and the iPhone searches for a cell signal. If, in fact, the iPhone doesn't work like that with a cell signal, is there a plausible reason why not?

Airplane Mode is different from turning Cellular Data off.

If all you do is turn off Cellular Data, your *telephone* still will maintain contact with cellular towers in your vicinity, because otherwise it cannot make voice calls.

Airplane Mode turns all of the device's radios off.

Wifi turns completely off or on, but only the Wifi radio.
