Although this sounds like a complete pain to complete, it’s actually very easy with only two steps…
- Put your iPhone into airplane mode… wait for the network to turn off
- Take your iPhone out of airplane more… success!
See I told you it was easy. You can also just power off your iPhone and reboot to achieve the same results how ever that takes much longer to do and if you’re in a hurry and just need to reset your DNS Cache then the airplane mode is a much better alternative.
